Key Discussion Points
- Maximizing Wealth Over a Lifetime
- Optimal Asset Allocation: Focus on maximizing lifetime expected utility, which translates to finding an expenditure stream that balances wealth and consumption while adjusting for risk.
- Dynamic Nature: Asset allocation should change throughout the life cycle as human capital diminishes with age.
- The Lifecycle Asset Allocation Changes
- Early life: High human capital allows for taking more investment risk.
- As individuals grow older and accumulate wealth, the allocation should become more conservative.
- Importance of building a buffer stock of wealth for unexpected expenses, especially in earlier life stages.
- Household Investment Patterns
- A significant gap exists between theoretical models and actual household behavior, particularly regarding stock market participation (with many households not investing in stocks).
- Common mistakes made by households when investing in stocks are tied to low financial literacy.
- Retirement Planning
- At retirement, the focus shifts to managing expenditures and longevity risk.
- Annuities: These are essential for hedging longevity risk but have low uptake due to costs and misconceptions.
- Impact of Automation on Wealth
- Automation in the workplace significantly impacts household wealth accumulation, with higher exposure leading to lower growth rates.
- Portfolio decisions are affected by job security and perceived risks, influencing investment behaviors.
- Education and Labor Supply
- Higher education levels correlate to better adaptation in the face of automation and more risk-taking in investment decisions.
- Households should diversify both their financial investments and their professional skills.
- Household Financial Behavior and Culture
- Peer effects and cultural influences significantly shape household financial decisions.
- Individuals often model their financial behavior based on the actions of those in their social circles.
- Financial Advice and Literacy
- Importance of financial literacy as a means to improve household financial outcomes.
- Advocating for personal finance education in schools to better prepare individuals for financial decision-making.
- Research Insights
- Professor Gomes highlights ongoing research that aims to simplify complex financial models into practical advice that households can employ.
---
Conclusion This episode emphasizes the need for informed financial decision-making and the potential for household finance to shape economic outcomes. Professor Gomes expresses a passion for improving financial literacy and making research accessible for practical application in everyday life.

Automatic transcript. May contain errors.0:03This is the Rational Reminder Podcast, a weekly reality check on sensible investing and financial decision-making from two Canadians. We're hosted by me, Benjamin Felix, and Cameron Passmore, portfolio managers at PWL Capital. Welcome to episode 262. This week, we welcome the professor Francisco Gomes, who is currently a professor of finance at London Business School, and he has his PhD in economics from Harvard. Ben, after we stopped recording with Francisco, you made a comment that is so true. There are so many brilliant people doing great work and there's so much information coming out of academia and today's conversation is an absolutely perfect example of that and it is so much fun to bring those findings to light.
0:51I mean, this is real practical findings that can impact anybody and as Francisco said, you know, households do care more. They need to have access to this information and it matters. This kind of information does matter. Yeah, he was talking about how there's less defined benefit pension plans now. Households are responsible for their own financial fates today more than in the past. A lot of this stuff is really important. My comment was that there's so much information like this, great information like this that gets stuck in academia. For the average person, it's just not accessible because the average person, even our average listener is probably not going to go and proactively read papers like this to help them make better decisions about the future.
1:33That's our objective with this podcast. We certainly accomplished that with Francisco today. Francisco's research has been published in top journals like the Journal of Finance, the Review of Financial Studies, the Journal of Financial Economics, and the American Economic Review. His main areas of expertise are household finance, capital markets, asset allocation, and macroeconomics. But he's got a practical bent to his research where it's like, how do you take this information and make it useful to households who are making real decisions with real information and real limitations and all that kind of stuff.
2:07And I think that's a lot of the takeaways that we got from this conversation were practical on that level. He's also a research affiliate for the Center for Economic Policy Research and one of the founding members of the CEPR Network on Household Finance. And household finance is what we focused on in this conversation. And as I've already mentioned, I think it was very valuable and again, very practically useful. He's such a clear communicator. This is just a fantastic conversation. So you're good to go, Ben, to our conversation with Professor Francisco Gomes. Let's go.
2:47Professor Francisco Gomes, welcome to the Rational Reminder podcast. Thank you, Ben. Thank you, Cameron. Francisco, when we talk about optimal asset allocation over the life cycle, what exactly is being optimized? Well, we're optimizing what academics call a lifetime expected utility. So think about maximizing wealth. So after all, who doesn't want to be rich? We can't want as much wealth as possible. But then we're going to convert that wealth into what we call a consumption or expenditure stream for our lives. So given that wealth, how much can we afford to spend every year of our lives? So that's kind of a first stage.
3:20And then the second part is that since the future is uncertain, we do the optimization based on what we expect our income to be or expect the returns on our assets to be. But at the same time, we do an optimization of a expenditure process that is going to be robust to that uncertainty so that we're prepared in case things don't go the right way. So instead of what we want to call risk adjusted. So in a nutshell, it's a bit like we want a high level, low risk expenditure pattern over our lives. That's the goal. Wow. That is a very, very clear explanation. Thank you. what are the determinants of optimal asset allocation for individuals?
3:55So just to first a brief disclaimer to say, you know, my research is mostly about investments in broad asset classes. So that's what I'm going to be talking about. So investment in risky assets, riskless assets is not about stock picking. It's not about investment in different asset styles, even along that I mentioned. So kind of sticking with those. So that being said, my research essentially has given that you're going to be investing in a broad asset index. So, you know, single bet of the S &P 500 index. So academics don't agree necessarily on many things, but they do agree that for most households, that's the best way you should invest in the stock market.
4:27Just take a low cost, broad stock market index. So no market timing of stock picking. So if you take that as one asset class and then they take, for example, you know, riskless asset, not asset class, so savings account, money market, mutual fund, whatever your favorite is, one area of research is essentially kind of how do you choose between those two asset classes and how does this change, particularly overall life? So how does this change over the life cycle? Why over the life cycle? What's so important about the life cycle is that a lot of our sources of income, sources of expenditure, our wealth accumulation, all of those change dramatically throughout our lives.
5:00And that matters brutally. So as we get older, our expected income path is changing. Now that income, if you think about it, the income that we earn for our lives is effectively an implicit holding of an asset. We call that human capital. So human capital is the present value of all our wages, all our future labor income, where the specific wages and labor income we earn every year, like the dividends that asset is paying. So like just when you have a stock, it pays dividends every year. This is kind of the same idea. So if you look at it from that perspective, you already have this asset and you want to think about how you're going to optimize your portfolio.
5:34I think the kind of this implicit asset is already there, basically. So that's one important factor. Another important factor is that you have your liability side. Of course, you have your expenditures, and those expenditures are not guaranteed. Those expenditures are not given. You have mortgage payments, interest rates go up, your mortgage go up. Late in life, you face medical expenditures. Those are very uncertain. It can be very high in certain countries. So it's a bit of this asset liability matching, essentially, that you want to do. And then you kind of combine this with how much wealth ultimately you have to invest.
6:06So, for example, suppose you have 100K of wealth and your target was, I'm going to want to have 50-50 in stocks and bonds. So, if I have 100K in wealth, I want 50-50, I put 50 in stocks, I put 50 in the bank, I'm done. But when you think about what I said before, you think about this human capital that you have, this implicit asset that you have. Well, then you already have some other asset out there and you should take that into account when you think about how to invest your financial assets. So for example, suppose the value of your human capital is also 100. What is this human capital? Is this a particularly risky asset?
6:42Is it a particularly safe asset? Well, for most people, it's a particularly safe asset. It just doesn't change that much from year to year. Our salary changes a little bit. There's a little bit of volatility. There might sometimes be big shocks, like we get unemployed, of course. But for most people, it doesn't change that much. The first approximation, and I'm obviously going to be more precise later, but the first approximation is very safe. It's like a safe asset already. So if we have a lot of this out there, when we're young, for example, we have a lot of this coming through the rest of our lives, we have this steady income that's going to come anyway, so we can afford to take much more risk with our financial wealth.
7:15So if I have 100 of financial wealth, but I have, say, 100 of human capital, then it's like those 100 of human capital is already an investment in the safe asset. It's going to pay this regular dividend that doesn't change very much. So what should I do with those 100 of financial wealth? Well, I should invest it all in stocks. And then I have my 50-50 again. If human capital is only 50, then what I do? Well, I invest 75 in stocks. So I have 75 in stocks plus 25 plus 50 gives me 75. So again, 50-50. So the crucial ratio that determines this allocation is basically this ratio of how much human capital I have relative to my financial wealth.
7:51If human capital is very large relative to my financial wealth, then I have a lot of this implicit riskless asset. I can afford to take much more risk in my portfolio. If this human capital is not very high relative to financial wealth, then I have to be a bit more conservative in my allocation, essentially. Can you expand on that a bit? How does optimal asset allocation change over the life cycle? So building on this, so when we're young, we still have kind of our whole trajectory of income, of wages coming up for the rest of our lives, right? So this human capital is gigantic. It's huge. It's maximum.
8:23We still have all our human capital ahead of us, and we haven't accumulated that much wealth. So therefore, this ratio I was just talking about is very, very large, a lot of human capital, very little financial wealth. So we can afford to take significant risk in our financial wealth because if things don't go well, we have kind of this human capital fall back on. As we get older and we start having less and less years remaining in which we're going to earn our wages. At the same time, if we're being prudent, we're saving for retirement. So our wealth is growing and growing. So this ratio is actually falling significantly because the numerator is falling and the denominator is increasing.
8:58So the ratio is just falling, falling very rapidly, which means we now should be converging to a more and more conservative portfolio. So this kind of gives rise to sort of these standard target date fund predictions or recommendations, right? If you invest in a target date fund, which these days is default option in many retirement DC retirement plans, they have this decreasing profile. And it's kind of based on this intuition that you kind of early in life, you can afford to take more risks. As you approach retirement, you can afford to take less risk because it depleted more and more of your human capital.
9:25So you have sort of this glide path until retirement. Now, this is a good rule of thumb for retirement allocation. But of course, when we think about our whole portfolio, it has to be a bit more complicated than that, because now we have to think about the expenditure side. We have to think about those income shocks. So early in life, you know, since I don't have much wealth, if I have an unemployment spell, or I have some major expenditure, or my car breaks down, or some major house repair, or medical bills, those can happen even early in life. If I haven't saved enough in liquid safe assets, then I might not have enough to cover those bills.
10:03So first, we want to make sure we build what is called a buffer stock of wealth. We have like a pot of wealth we can fall back on if things go bad, in terms of the income side or in terms of the expenditure side. So first, we want to build that buffer stock. And that buffer stock, since it has to be available there as sort of an emergency fund, it has to be invested in relatively safe assets and relatively liquid assets. and it should be about six months to a year and a half of our wealth basically depending on how large these risks are as we accumulate more and more wealth then we should just start putting more and more in stocks because we can afford take risk and also at some point we have enough wealth this buffer stock becomes less relevant because if i have significant amount of wealth even if i lose 10 15 on the stock market you know i still have enough and if i invest in that low cost broad index fund losing more than 15 in a year in the stock market is very very rare so if i kind of following that trajectory then i'm just going to be investing a lot in stocks so if you want to think about a simple rule is if you have like a graph where you plot sort of on the horizontal axis your age and on the vertical axis you have your allocation to stocks or risk assets in general it should be kind of like a hump shape so you start more or less moderate early in life because you want to have that buffer stock in a relatively safe facet to a large extent.
11:20Then you increase sort of towards 35, 40 years old. You kind of max out over there. And then you kind of sort of gradually decrease towards retirement. So that's kind of the standard profile or standard prediction that most of these early models would predict. More recently, I've kind of deviated a little bit from that, I must say, to the extent that we're on the last part, you know, that glide path towards retirement. So there's a bit of dispute among academics about how much more comfortable people are in taking risks as they get richer or not. So some academics think that there's not much evidence that people become more risk lovers as they get richer.
12:03I think that by now, especially in this context, the evidence is overwhelming that they do, that people feel more comfortable taking more risks as they have more wealth. and so that kind of counteracts this idea to decrease significantly your allocations as you get older because you're becoming richer and richer so now my recommendation is more kind of a mild decreasing path or even a flat one so for example myself i'm calling a flat one i'm not decreasing my allocation and i have no plans to decrease it as i approach retirement so that's kind of in a broad sense the light path of allocation over life that's really interesting You mentioned, so clearly, human capital was important or labor income was important, everything we just talked about.
12:43How important, though, is pinpointing the exact riskiness of labor income in making asset allocation decisions? The risk itself is actually not super important for the asset allocation. So the risk matters quite a bit early in life for that buffer stock that I was talking about. So that's why I said it can vary between, say, six months, 18 months. If income is very risky, we have a lot of risk in terms of expenditure side, you want a bigger buffer stock. If it's smaller, you need a smaller buffer stock. but that's mostly it the risk of labor income matters more is actually for determining your savings so when you think about saving for retirement then you want to think about more sort of this more persistent this career uncertainty and you want to think about how much do i need to save for retirement i need to have a sense of kind of what's going to happen to the growth rate of my income over over life and what's the trajectory i need to have in terms of savings for that is extremely important for determining savings for determining the asset allocation is less important understanding that it is labor income and how much we have is crucial well, the risk itself matters a bit, but it's not.
13:38To a first order, we can kind of leave it out, which is why I kind of started with this idea. Suppose labor income is safe. Try and keep a kind of a simple method, a simple rule, because to a first approximation, it's not a huge deal if we kind of leave that out. What effect does flexible labor supply have on optimal portfolio allocations? So it's actually kind of a similar story. So for portfolio allocation, not too much, but it matters a lot is for the savings decision. So when I think about saving for retirement, I don't know what my future income is going to be. I don't know what future returns are going to be.
14:07So if I start the savings path and then I approach retirement and I haven't saved enough, I'm in trouble. If I have flexible labor supply, if I can adjust my retirement date, if I can work a few years longer, if that happens, then I need to have that much pressure on my early savings. I need to over save if you want, because I can sort of adjust gradually. That's extremely important. For asset allocation, on the same logic, I don't need to be as conservative. I can be a little bit more aggressive because I know I have that extra margin to adjust. But in most calibrated models, the difference is not huge.
14:35The big difference is essentially the savings dimension. That can be very, very important. Okay, this is really interesting. So labor income, the relative safety of labor income affects how much you need to save. How does level of education affect the riskiness of labor income? That's very interesting because it operates actually in different ways at different levels of education. So for the less educated households, they face a lot more of what we call these transitory income shocks, meaning they have higher probability of being unemployed, they have less steady jobs, so more fluctuation of their earnings from year to year, which means they exactly have a higher demand for these precautionary savings, for this buffer stock.
15:13They really need to have a bigger pot to insure against all these things. They need more conservative portfolio locations, more liquid assets because they need to insure against these. Higher educated people, people with college degrees and so on, what they typically have is more what we call career uncertainty. So their income is higher, but the difference between income of college graduate and say high school graduate is particularly noticeable from age, say, 35, 40 onwards. It starts being kind of similar and then it just grows fast typically. And so they become very, very different over time.
15:42But what we don't know what there's a lot of uncertainty is exactly how fast it's going to grow. There's a lot of variability there. And so it kind of goes back to this notion about optimal savings for retirement that for more educated households, they can be more aggressive in your allocation. but you have in a sense you have more uncertainty about how the optimal savings because you have a lot of uncertainty about exactly what trajectory it's going to be if your income grows a lot then ideally i wouldn't save too much now i'd save more when i can afford to save later in the future but if later on it doesn't grow as much as i thought well then all of a sudden i have to catch up in a few remaining years so for more educated people is more an issue in terms of the savings for less educated people it's definitely an issue you really need to ensure against these shocks, you need to have a big buffer stock and a more conservative portfolio, essentially.
16:27How can households practically use a life cycle asset allocation model to make asset allocation decisions? So the models can be as complex as one wants almost because there's so many things you can fit into them, mortgages, rentals, medical shocks, expenditure shocks, income shocks, and we're talking about transit or permanent retirement account, non-retirement account, tax incentives, et cetera. That's why it's important to focus on sort of simplified the kind of takeaways from those models. And so that's why, for example, talking about human capital being kind of riskless, even though it's not 100 % riskless, that's kind of an approximate insight.
17:01But, you know, some main takeaways you take from those models are these ideas of, you know, build that buffer stock early in life. It's very important. We don't have much wealth when we start off, so we can't afford to take much more risks. We need to make sure we kind of are insured before we kind of get on to investing in Bitcoin or whatever it is we want to do. So we need to make sure we have that pot there. and then the second takeaway is that retirement investing for retirement you can start by investing significantly in stocks because you have this labor income coming in and then you can i don't know decrease gradually if you want to trust initial advice so if you feel confident taking more risk as your wealth grows you probably can even remain more or less flat this other takeaway know that the safer your labor income is the more aggressive you can invest in your portfolio the more uncertain in general, in your expenditures and everything else, the more conservative your portfolio should be.
17:50So basically, it's takeaways about risk and the human capital, essentially. These are the main lessons I would want to express. Yeah, interesting. So people don't have to necessarily compute, run the model. They can just use the intuition to think about their asset allocation decisions. Yes, that's absolutely important because there's, well, in many things, people are not specialists in these issues. So if you're going to try and give very complex messages and very complex rules, people either won't understand them or just won't follow up. So even though as an academic, you have my exact rule goes here and goes down there and whatever, I mean, that just doesn't fly.
18:26You know, as much as kind of pains after you saw a complicated model to kind of strip it down and simplify it. If you want your research to be useful for anything, you have to do it. Otherwise, it's not going to have an impact on people. And ultimately, that's what you're doing research for. How does owned housing affect optimal portfolio allocations? Housing affects mostly sort of two channels. One is kind of an indirect one, which is that when we buy a house, we typically spend a lot of our money buying that house. So our wealth falls significantly. So if you think about that ratio I was talking about as being crucial, human capital to financial wealth, all of a sudden we just depleted a lot of our financial wealth.
19:02So that ratio just jumped a lot. So you have that kind of indirect channel there. And the second one is basically the fact that when we buy a house, all of a sudden, we typically increase our background risks and expenditure commitments. What do we mean by this? Expenditure commitment is basically sort of some expenditure that we sort of kind of committed to, and it will be unbelievably costly to cut. What is one of those things? Well, this example is a mortgage. Typically, if we buy a house, we buy it with a mortgage. If we don't pay the mortgage, that's going to be extremely painful for us. So all of a sudden, we have that commitment.
19:33So we need to make sure that, you know, that buffer stock of wealth that we talked about kind of covers that commitment as well, because it has to, basically. And the other thing is, once we have a house, in the West, a little bit less because, you know, you guys, not you guys, sorry, it's Canada. I don't think Canada has the same. This idea of, you know, very long mortgage, fixed rate mortgages are possible in most other countries. They're not. And so households, when they buy a house, they're typically exposed to a lot of interest rate risk. and so that's a significant background risk if interest rates go up tomorrow then mortgage rates are going to go up and then you're stuck okay so you need to kind of insure against those risks households when they buy a house and a mortgage in most countries that's variable rate mortgage are only fixed for a few years which means you're going to be exposed to a lot of interest rate risk so if interest rates go up in the future then well all of a sudden that commitment just went up just went up significantly so for that reason again you need to have a much more conservative portfolio when you're stuck with this risk.
20:28So it kind of goes back to this background risk channel again. How did the empirical lifestyle asset allocations of households compare to theoretical predictions? So if you take this simple model, and I'll explain in a moment what I mean by the simple model, the major gap between theory and what households do is the fact that about half of households, even in most developed countries like the US, for example, just don't invest in stocks at all okay so that's like the biggest gap people don't even invest in stocks at all uh if you go to several other countries you know it's even less than that you have many western countries where it's 10 15 percent of people invest in stocks and that's by far the biggest gap and the most costly gap the relative theory is not not invest in stocks and i have this very simple example that i have in my personal finance class and i kind of have the numbers here i don't remember the exact numbers obviously it's take somebody who invest who started investing for retirement in 1981 so 1981 he puts say a thousand dollars aside to invest retirement and then 40 years later you collect that money so 40 years later you retire 2021 you collect that money if you invested in t-bills or a savings account then inflation adjusted those one thousand dollars would have become 1 284 so that's a 28.4 cumulative return if you invest in the diversified stock market index, and my example is the MSCI World Index, those same$1 ,000 would have become$12 ,410.
21:56Again, inflation adjusted. So that's a staggering difference. That's nine and a half times more wealth that you have here. And I didn't pick any particularly nice Peter for the stock market. This period includes the dot-com bubble crashing, includes the financial crisis. So that's the worst decade in the history of the stock market period. So that's just a massive return you know if the first person saved enough for one nice vacation a year the other person has enough for nine nice vacations a year and some money to spare okay that's basically what we're talking about okay so of course i know i'm exaggerating a little bit because you know you'll be saving every year so not all money will accumulate over the whole 40 years but that's kind of the idea and the thing is most people just have no sense of these numbers actually if you don't have a finance background you know if you were to just go on the street and pose this as a question to individuals, to random individuals, you know, put the money in a savings account, put the money in a stock market, how much did you get 40 years later?
22:51Most people probably give very similar numbers. They're not aware of kind of this massive return that the stock market offers. And that's one of the reasons, you know, one of the reasons why people don't invest so much in stocks or don't invest at all in stocks. And that is basically the biggest deviation from what I call the simple model, the most costly one. Why do I say simple model? because, of course, that simple model assumes that people know those returns, right? And that's why they should invest, right? So if you have a model where you assume executive people need to collect that information about those returns, that not everybody is a finance specialist, just like everybody is a specialist in law or in medicine or in engineering.
23:27You know, we know what we know, right? And the world is becoming more and more specialized and becoming harder to know many things. So those who know finance know this. Those others who have a hobby like finance and research this stuff, they will know this. Others don't need to know it, just like those are not interested in law, don't know law. And so that is basically kind of, once you incorporate that in the model, then you can sort of match that. Now, for those who actually invest in stocks, then we have a lot of other things, such a lot of people don't invest in those low-cost, broad-index funds that I was talking about.
23:59So they pay high fees, and they face unnecessary risks because they don't have a classified portfolio. Some people trade too much. So they trade frequently because of an overconfidence or other reasons. And so that means they end up paying a lot of fees. Even if you invest in a broker that has zero trading costs, you're still paying bid-ask spreads and other things. So you're still going to be paying. People tend to be return chasers. That's another thing that we see. So, for example, if you observe a mutual fund that does well two or three years, people just slow money into it. even though academic research overwhelmingly shows that there's absolutely no performance persistence or close to non-performance persistence there.
24:36So there's those sets of mistakes, even for people investing in stocks. Those outside are kind of the biggest sort of deviations from what the model would recommend, basically. Do you think a lot of that ties back to financial literacy? Oh yeah, absolutely. I mean, a lot of it is financial literacy. Some of it is behavioral biases, right? I was saying like the overconfidence, you know, the trading too much, you know especially you trade once you made money all of a sudden you think oh i'm a great investor i'm going to keep on trading and trading and trading so some of it is some of those behavioral biases that we have but a lot of it is lack of financial it is a big big big problem and again it goes back to it's getting harder and harder to be a specialist in everything everything is getting more complex if we want to know want to be good at our job we have to focus more and more and more and more on it it's harder to know anything else and a lot of people are just not interested in it anymore, right?
25:23You know, just like some people are not interested in learning medicine. The doctor would tell me something, you know, I'm not interested in learning how to fix the plumbing and I'll hire a plumber. I know the same thing for finance, you know, people are not interested in learning that, but then of course that can come with a big cost in terms of financial decisions. Back to asset allocation, how does the process of optimizing asset allocation change at retirement? So there's no more human capital. How does that process change? So yeah, so at retirement, our sources of income are pretty much set exactly.
25:51You know, we have social security we have you know defined benefit pension plan if we were lucky enough to have been enrolled in one and still have one of those so it's basically about two things it's basically about managing our expenditures that's where a lot of the uncertainty is going to come now particularly if you're in some countries which might not have you know a great social welfare system in particular great public health care system you know then things like medical expenditure bills can be huge plain life care can be very expensive as well and the second thing is about managing longevity risk, making sure that your money lasts for as long as you need it.

26:24And if you time it right, not too long. Okay. So we don't know how long we're going to live for. And that's a big thing. I can save gradually to make sure money lasts for a long time. But then if I die early, that money went unused. And if I run out quickly and I live longer, then it's great. I'm living longer, but I'm really suffering in those last years. So those are two important things. And then, of course, there's another maybe more complex part or more tricky part. If we think about leaving bequests for our loved ones or someone else, we have to think about what are the best vehicles for doing that in terms of tax reasons and when they're going to get access to funds and all that.
27:04That's a different type of optimization there, essentially. How important is hedging longevity risk to retirement portfolios? Very, very important. This is what we're talking about. I mean, if we just don't know how long we're going to live, if we end up thinking we're going to live until age 85, time to run everything down until age 85. Then if I live until age 90, I mean, that's five years. That's a lot to finance at a time in my life where it's very hard for me to earn any extra income. When I'm 85, I'm not going to find a job. I'm not going to be able to just earn new income. So in that sense, I want to be cautious.
27:37But if we're too cautious, again, if suppose I save, okay, let me then plan for 90. and then I end up dying at 75. You know, hey, I could have had twice as many vacations or whatever. And the money goes unused. So longevity risk is a big problem. And hedging is important. There's this financial instrument exactly designed for that, which are annuities, right? So annuities is a financial product that is exactly designed to hedge longevity risk. Annuity is a financial product that you buy it and then it pays you a regular payment every year as long as you're alive. So you exactly converted your money into a stream of payments, pays exactly while you're alive.
28:11It doesn't stop before, it doesn't stop any longer. So if you live longer, the payments continue perfectly, essentially. So annuities should be an important part of the portfolio of all retirees. And in fact, if you want to be even more financially sophisticated, I would say you probably might even want to start thinking about deferred annuities even during working life. So annuities allow you to hedge this longevity risk when you retire. So I have a pot of money. I don't know how long I'm going to live. I'm going to convert a fraction of that into an annuity. So I'm guaranteed I have that payment during retirement.
28:40So I kind of manage this allocation of wealth over retirement. But when I'm saving, when I'm 30, 40, whatever, and I need to think about how much do I need to save for retirement, I have the same problem back then. I do think how much do I need to save for retirement depends on how many years I think I'm going to live in retirement, right? So I haven't kind of hedged longevity risk yet. I can sort of do it by what is called a deferred annuity, which is basically an annuity that starts paying off at a deferred date, say the retirement date. So if I want to be even more sophisticated, I can already start investing some of my money in these deferred annuities and start kind of already hedging a little bit of that risk early in life and making financial planning easier even before retirement, essentially.
29:20We agree that all makes sense. But we have this thing, of course, that you know about called the annuity puzzle. Why do you think annuity uptake is low? A lot of reasons there. So for low-income households, it's not so much an issue because low-income households have social security. So we all have social security. Social Security is an annuity, right? Social Security is exactly that way I described it. It pays us money every year as long as we're alive. So we already have that annuity. For low-income households, Social Security has a high replacement rate relative to your previous income, meaning you get a very high fraction of your pre-retirement income.
29:50So you already have a high level of annuitization there. So you don't need necessarily more. Historically, a lot of people are also enrolled in defined benefit pension funds in most countries. In several countries, they still are, right? So that's also an annuity because that's also going to give you a payment when you're retired. So for historically and in several countries for middle income households, you're also kind of largely covered with annuities to some extent. Now, of course, again, countries are moved to defined contribution. That's no longer the case. And as you move beyond that, it's no longer the case as well.
30:21So the issue, a lot of issues, you know, relates to fees. For example, annuities are expensive and particularly variable annuities are expensive. So what do we mean by this? I can buy an annuity that is called a fixed annuity, a fixed payment annuity, which means it's just going to give me a fixed payment every year. But what gives me a fixed payment every year? Well, it's investing in a riskless bond, right? That's what gives me a fixed payment every year. So effective variable annuity is like a position in a fixed bond. It's going to give me kind of that return in a sense. That's how the annuity provider is going to price it to me.
30:51So that's effectively the return I'm getting. So if I put everything in this fixed payment annuities, I'm basically going to the equivalent of having like this low return on the riskless asset, which is, we already said, is very suboptimal and puts this huge pressure on my savings if I'm owning that low return. So ideally, when I'm retired, I want to continue having exposure to the stock market. For that, I can buy a variable annuity, variable annuities in which payments are, say, linked to a basket of stocks, for example, the S &P 500 or something like that. And it pays related to that and continues to give me that exposure.
31:22That's great. Those, unfortunately, have fees. And actually, often have fees unnecessarily or kind of prying a little bit on or high fees and necessarily kind of taking advantage a little bit of some of our behavioral biases or fears because a lot of these annuities, for example, what they have is something like a minimum return guarantee. Say, okay, you're retired, so we're going to give you the S &P 500, but we give you a floor of, say, zero, for example. So you can't lose. The return can be less than zero. Now, return for giving you a floor, of course, we have to take a fee. That's like giving you the index plus a put option, right?
31:55So we have to charge you for that put option. which you can't have yourself because you can't manage that position. You can't buy a long day to put option anyway. So we're going to charge you a fee. And those fees, every time you kind of go and price these things, you see that the implicit value of that put option is just gigantic, basically. So to have kind of that open portfolio, continue to have that equity exposure at retirement, you typically have to pay a lot for it, essentially. So you kind of have that trade-off. Do I want to kind of annuitize more or do I want to kind of pay these fees?
32:24And then the other issue, of course, is if I annuitize everything and then something happens and I have a big expenditure shock, then I don't have money for that. So there's only so much we kind of want to annuitize. So there's a combination of these factors, but as you pointed out, it's called annuity puzzle for a reason. So when we put all these things into models, we can't fully explain it yet. So there's certainly more to it than what I'm saying. Absolutely. Interesting. I like those comments on the variable annuities with the floors and stuff like that. We did an episode not too long ago on structured products and I think made a lot of the same points.
32:56Okay. Yeah, absolutely. Who was it, by the way? That was just us. We alternate between guests and just us talking about stuff. Okay. Cool, cool, cool. So Francisco, you mentioned limited stock market participation. Can you talk about how stock market participation changes over the life cycle? Yeah. So it starts by being relatively moderate because early in life, we just don't have that much wealth. So we're not going to invest too much into the stock market just yet. Then it increases sort of rapidly until age like 40 as people start accumulating wealth and start saving for retirement. And that is even more the case if you start focusing on people who actually have defined contribution pension plans, because obviously there you typically automatically become enrolled in a pension plan that these days, most cases, the default has some equity exposure.
33:41And then it pretty much stays flat until sort of retirement. And after retirement, then it starts dropping. As people start using up their wealth or people kind of converts, are too worried about the risk of retirement and become good, more conservative portfolios, starting with people kind of decreasing their participation in the stock market. So related, how do wealth and human capital affect stock market participation? Both positively. So the more human capital we have, the more risks we can afford to take. So you find an uptick in participation when you have more human capital. But the bigger one is by far wealth.
34:16I mean, if you want to think about what's the biggest thing that explains participation in any cross-section, in any data you look at, it's just wealth. That's a variable that just jumps 100 times more than anything else. So the more wealth we have, the more incentive we have to learn about different investments or learn how to allocate that wealth, the more cost-effective it is to hire financial advisors or wealth managers or things like that. So wealth has a strong, strong positive impact on participation. Interesting. Okay. So that would support the comments you made earlier about the costs of participation being what prohibits people with lower wealth from participating.
34:51Exactly. Exactly. Interesting. Okay. I want to move on to an incredible paper that you did on automation and wealth dispersion that I think touches on a lot of the points that we've been covering. So what effect does automation at the workplace have on household wealth accumulation? So in that paper, we find that exposure to automation. So if you look at workers in industries, they have higher exposure to automation, lower exposure to automation, kind of compare differential. We find that if you say group one third highest exposure, one third lowest exposure, the difference in the growth rate of wealth is about 2.5 % per year.
35:26So that's huge. That's a very, very large difference in wealth accumulation over time for the ones who have more and lower exposure to automation. So it's a very big impact. How do you measure exposure to automation? So we have the data set that kind of sees the number of robots that get added and we kind of figure out exactly how much each industry has. So it's industry by industry, basically. So we don't have exactly kind of this occupation that's replaced versus that occupation that's replaced. But you see in this industry, more automation came in, more jobs got displaced versus that industry, which is why we're talking about grouping workers.
36:01They're working in industries with higher displacement versus workers that work in industries with lower displacement, basically. Through what channels does automation affect wealth accumulation? So the main one is income, right? As we get displaced and we end up losing jobs. But the thing we bring up, the point we bring up in this paper is sort of a novel channel people haven't looked at, which is a portfolio relocation channel, which is the idea that workers who are in industries with higher displacement risk due to automation, they're actually going to change their portfolio location. They become more conservative.
36:32They're more likely to exit the stock market. They are more likely to move to more conservative portfolios. and that means a lower return on their wealth. That lower return on their wealth means, well, less wealth going forward and it's a non-trivial component of the differences in wealth and inflation that you actually find. That's incredible. That's like the buffer stock conversation we had earlier, whether human capital gets riskier because of displacement of risk and that's why they changed their portfolio. Is that kind of the idea? Yeah, absolutely. That's why it's kind of a nice application of what we've discussed before into this context.
37:01It's kind of sort of a nice, okay, let's bring this to this channel. I think it's going to be operative here and we think can be a significant channel. And it was there in the data, we found that it was, and we're happy to discover that. So in one sense, it makes a contribution to this particular study, this particular literature, and it also goes back to kind of making a contribution in terms of kind of providing evidence of these background risks in this context. So it kind of, you know, sort of if you want, sheds light on both literatures. So how much of the effect is explained by changes in household portfolios in response to the automation?
37:32We find it's about one sixth of the fact, which is big enough to be important. And of course, you'd expect income to be the major one. So if it was more than that, we would probably look at it for much more than that. We'd certainly look many, many times at the data and see, okay, we must be missing something. But yeah, it's large enough to be quite important. That's incredible. So people more exposed to automation, they're going to be affected by their income being reduced or lost. But one sixth of the difference in wealth accumulation is explained by changes in portfolio allocation as opposed to changes in income.
38:04Exactly. Exactly. That's incredible. That's an incredible finding. Thank you. Really interesting and surprising. How does education level affect the interaction between automation and wealth? So we talked before about how this is a world where it's becoming harder and harder to know about a lot of things, where if we want to be good at our job, we have to keep specializing and specialize because every task, everything just becomes more and more complex. So workers are becoming more and more specialized. And unfortunately, that means we're becoming more and more vulnerable to displacement shocks.
38:36You know, some new technology comes, automation affects a particular industry or a particular job, and suddenly some tasks become obsolete, or sometimes even the whole sectors can become obsolete. And so that's a bigger risk that we're facing these days, essentially, as we become much more and more specialized. And so that's exactly what we find, that workers that have human capital is less transferable across industries as proxied by having education is above the average within your industry. And those are less affected because they can sort of reallocate more easily to another job, to another industry when automation comes.
39:10Those that have less transferability of human capital, those that get hit the most, essentially. So education makes human capital more transferable. What makes it less transferable? Is it just lack of education or are there other factors there? Lack of education. I mean, I guess the type of industry that you're in, you know, the certain industries by the way have knowledge that is more transferable than others. So in that sense, I mean, it depends on the tasks and depends on the industries. And if you're a secretary, you can be a secretary in many different industries. You know, if you're a secretary in IT, IT disappears, fine.
39:43You can only be a secretary in a bank. So it depends a little bit on the tasks, basically, that you're on. Given this information, how should households respond to automation at work? So we talked before about investing in a broad, diversified stock market index, diversifying financial wealth. Well, this says that we should diversify our professional skills as well. Try not to have all our eggs in one basket. You know, it's great to be coming better and better and better at our job, but it's always good to broaden our skills, to keep refreshing our skills and to keep our options open, to keep our human capital valuable and resilient to these shocks.
40:17So, you know, if it's too costly to continue taking, you know, courses, of course, in terms of either money or time or whatever, just read books, tutorials, listen to fantastic podcasts like the one you guys have. Just try and get knowledge on different areas more and more and get ourselves more resilient to all these shocks. I'd say that's a strong message that comes across. That's a huge takeaway and having empirical support. That's kind of a thing that I think a lot of people recognize that is probably a good thing to do, but having this type of empirical support for it. I find this paper to be mind-blowing personally.
40:51Thank you. I appreciate it. This next paper is actually also mind-blowing. This one, you looked at how household expectations change based on changes to finance. How do changes in someone's financial situation affect their expectations about the future? We have evidence in many different concepts. People tend to be what we call extrapolators. If you see too much of something, you think that that's going to continue. I mentioned before the mutual fund case. You know, people see mutual fund doing well for two, three years, then the money pours into it because they think it's going to continue doing well.
41:21So that's what we call kind of extrapolation. It doesn't happen in all settings. Actually, in our setting, it doesn't happen always. But it's sort of fairly common in our general rule. Here, we look at individuals' expectations of their financial situation. And we find that although individuals extrapolate when income increases, so they expect it to increase again, or extrapolate when the expenditures increase, they expect it to tend to increase again or the expenditures decreased expect them to decrease again when it comes to income drops when the income falls is the opposite people actually expect a reversal expect income to recover which to some extent is fine because that's typically the nature of things you know we get unemployed can't get any lower typically so income should rebound the problem that we find is that people expect it to happen too quickly and too much so So people expect that recovery to take place too quickly relative to what it's observed in the data.
42:15Essentially, that's the concern. So what characteristics affect how an individual responds to a change in their finances? So basically, it's the type of shock and the nature of the shock. So if you think about this two-by-two matrix, it's like income expenditure and an increase decrease. So we find extrapolation across all except in that box of income and decrease. There, we find this expectation of reversal, basically. How accurate are the expectations that individuals form based on their current experience? Well, unfortunately, they're all exaggerated. Take any point on this box, and it's all too much.
42:49When they expect extrapolation, they expect it too much. If your income increases, people tend to expect to increase too much relative to, again, in the future, relative to what we're actually observing the data. As I mentioned, when the income drops and people expect to revert, they expect to revert too quickly or too much relative to what is in the data. They exaggerate in all dimensions, basically. And how do personal experiences affect optimism or pessimism about the future? There's this strand of research that shows that kind of suffering or going through some real salient events kind of stays with us and sort of shapes our beliefs going forward.
43:23So for example, if you live through a big recession and you tend to be more pessimistic about employment outcomes, if you live through a period of high inflation, you tend to be more worried about hedging increase in inflation. If you live through a stock market crash, you're less likely to participate in the stock market. And here we find the same. We find people who lived through long recessions, periods in the past, and they're more pessimistic about changes in income going forward, essentially. Beliefs kind of run employment spells and so on. They tend to on average, compared with everybody else, they tend to have more pessimistic beliefs, essentially.
43:54Interesting. So households have these expectation errors. What are the impacts on their future finances? So that's basically where we kind of take the second part of the paper, because focusing on this idea that if your income drops you expect to revert too quickly how bad is that well when if our income drops what are supposed to do what a normal optimization model say well that's why we save that buffer stock of wealth that's why you had it to ensure this drops in income so tap onto it use that money to kind of smooth your consumption so you don't have a big drop in consumption or maybe in some extreme cases you know even borrow a little bit and then repay that later on on your income rebounds but how much should you borrow and how quickly should you deplete that buffer stock depends of course on how long your income is going to stay low for if it's a small period then you can deplete a lot because you're going to be back or you can borrow and you're going to pay quickly if that's what households think that's what they do and that's what we observe basically them decreasing their savings and increasing their borrowing but since income doesn't rebound that quickly then you might easily find yourself in a situation next year again you need to deplete your savings but you don't have them anymore, or you need to repay your loan, but you can't afford it.
45:06And in worst cases, that can lead to the usual concerns of debt spirals, or now you have to repay your debt plus the interest and just get in a really bad situation there. What are the lessons from this research for households thinking about the future after a change in their financial situation? Well, the main lesson I'd say is don't take the future for granted. That's basically, don't think income is going to grow until it actually grows. Don't take that promotion, that new job, coming out of the unemployment spell, the reduction in mortgage payments, whatever it is. To use the old expression, don't count your chickens before the eggs are hatched.
45:40Be prudent before you got thinking about how the future is going to be great and so on. Incredible. All this stuff is so relevant to financial planning. Although in finance, you call it household finance, we call it financial planning, but they're the same thing in a lot of ways. Why is it important to the study of finance to understand all the stuff we're talking about, how households make financial decisions? So households are key to any economy. We can think of economies where banks don't really matter. We can think of economies where capital markets don't really matter. We can think of economies where pension funds don't really matter.
46:15But you can think of an economy where households are not there and they're not key. So they're not the lifeblood of any economy. You know, two-thirds of GDP is private consumption. So households save more or less or consume more or less. Recession, expansion, follow. So, you know, how households allocate their savings determines who gets capital, who gets funding in the economy. So it determines the cost of borrowing for governments, determines the cost of capital for firms. So all of that comes from that's a supply of funds for anybody in the economy. So understanding that is obviously very important.
46:44That's kind of from a macro side. But then, of course, you can think of, you know, micro side and like what determines wealth inequality? How much risk sharing is there? We talked about retirement savings. Are households saving for retirement? which percentage is saving well, which percentage is not saving enough. If not, should we do something about it? And what's the best way of changing that? Are households prepared in case interest rates go up or have they borrowed too much and borrowed too much at floating rates? Are households prepared if a recession hits or have they have enough buffer stock that we talked about?
47:13So that's going to determine what happens if we change taxes, if we change government expenditures. So for all of those things, you know, households are crucial. You know, and understanding households is, I would say, the number one thing we should do as economists, of course, I'm biased. But that's my take, basically. Yeah. So why has household finance taken off as a field of study in relative recent history? So I'd say a combination of three reasons. One is data. We can write models, whatever we want. But if we really don't have data, we're writing models mostly for the sake of writing models.
47:48So now we have a lot of data. We're studying more and more and more and more data that allows us to look at a lot of issues we couldn't look at before, allows us to learn new things that we hadn't learned before. So that's been a major revolution in household finance, the amount of data available in the last couple of decades or so. The second is the fact that households have become more and more important in the economy. Talking about this transition from defined benefit to defined contribution links exactly to what I was talking about before. Now households are much more directly responsible through their decisions about how capital gets allocated in the economy.
48:20and so the cost of capital companies boring for governments etc and the third one is kind of related to that you know now households care more you know if i have a social security if i benefit pension fund then 80 of people don't need to think about how to save just a little buffer stock of wealth that's how much you're going to have throughout your life that's it you know just rich people need a wealth manager and that's it now all of us need to think about oh my god how much do i need to save for retirement where do i put my money in addition to of course other things We always had thought about how to get a mortgage and things like that, but there's just more and more financial decisions that we have to do as individuals.
48:55In a way, houses are now more important, both for policymakers and for regulators. There's just a lot of data out there, basically. This combination just made the field explode, and that's fantastic. We talked earlier about simplifying down the lifecycle model to make it more practically useful for people. How do you think that the study of household finance more generally is best applied to improving outcomes for households? Oh, I think kind of exactly what you touched. So on one hand, we're going to need to be solving more and more complex models all the time because we want to incorporate all the different things.
49:25But we have to translate them into these simple rules of thumb that people can understand and people can follow. Otherwise, it's just not going to work. Otherwise, we're just writing these models. I know maybe they can get published, but it's not going to have an impact. So I have to understand most people know a little about finance, just like most people know a little about law, about engineering, about plumbing, about whatever it is. So we have to be able to convey these messages in a way that they're simple rules, simple guidelines that one can understand. And I think we haven't – some people are amazing at that.
49:59There are several academies I totally admire because they're really amazing at that and they've been doing a fantastic job in that. But in general as a profession, I think we're lagging. I think we're not doing a good job of that. And I think we need to do better. That's so interesting. So it's like, there are a ton of bad rules of thumb out there made by non-economists, I guess, but now economists have to make some good rules of thumb that are actually useful for people. We talked to James Choi recently and he called this - Oh, he's one of those I was thinking when I was thinking that I admire.
50:26James, James is amazing. James is fantastic. We had a great conversation with him, but he called this practical finance. He wants to make that into a field. Yeah, absolutely. I mean, James, yeah, I always love reading James's papers and seeing what he's doing. He's now started teaching this amazing personal finance course at Yale that he's a fantastic guy. Yeah, absolutely. How do peer effects influence household financial behavior? So peer effects, that's one of the great things that we can now study with all this data. Now we have data, no one tells us how people are connected on Facebook and neighbors and coworkers and so on.
51:00And we found strong evidence that peer effects matter quite a bit, that people learn a lot or copy a lot in their peers. So if your co-workers are more likely to take on that default 401k allocation, you're more likely to do the same. If your neighbors are more likely to invest in the stock market, you're more likely to invest in the stock market as well. So we see copying kind of from all these channels, neighbors, co-workers, social connections, and just explains a lot of effects. It's not second order. Which comes in line with this idea that people are not experts in all these things. So you kind of follow different rules, you know, and okay, these people are doing this and it seems to make sense for them.
51:39And of course, sometimes in the right way, sometimes in the wrong way, sometimes, you know, this person is not saving for retirement. It seems happy. Let me do the same. Well, of course you haven't seen what's going on when that person retires. So sometimes the copying is good. Sometimes it's bad. So I'm not saying it's good, but it's in line with this idea that people are kind of grasping at getting information from anywhere pretty much. What about culture? How does that affect behavior? It also matters. So naturally, we kind of carry our culture with us in many settings. And now we have evidence that financial decisions are also impacted by our culture.
52:11So if you look at sort of immigrants from countries with high savings culture, they'll typically save more than the locals. If you look at immigrants from countries which have a bigger trust in the financial system, they're more likely to invest in the stock market. So we find that actually this cultural phenomenon actually matter also in the financial domain, which is sort of another cool set of results that people have been able to kind of identify with this in more recent times. That is very cool. What role do you see for financial advice in improving the finances of households? So the potential is huge for the reasons we discussed before.
52:43So, you know, we don't fix our plumbing. We have the plumber. We don't learn medicine. We have the doctor. So a lot of people don't know about finance or don't care or don't want to learn about finance. They want to be able to delegate to somebody. So the financial advisors can have an important role. Traditionally, of course, problems there is, you know, a lot of them are not independent financial advisors. There's issues of conflict of interest. Those things have been improved in terms of what they have to disclose and the fees they have to charge. So things are getting better. But the potential in general for advising individuals is huge.
53:12But in fact, I'll go even one step further. I would say, you know, we should even start at even an earlier stage. which one thing I've always argued is that we should be teaching personal finance at high school. You know, high school is the point where everybody can learn about these things very easily. I mean, these are not complicated things if you explain them in a course, these simple rules. And just think about what it means if you teach people already when they start their life about the importance of saving for retirement, how much is to save for retirement, what's a mortgage and how you handle a mortgage, how you manage your credit card debt, the different types of insurance.
53:48I mean, the difference that it can make to people's lives is just huge. I think everybody should be learning these things in high school. That's one thing that I know I've been arguing for a long time, basically. Interesting. When did you start teaching a personal finance course? The personal finance course actually is something I only started teaching about five years ago because I'm in a business school where we don't have an undergraduate degree. So we only have MBAs in business education courses. So personal finance traditionally was not part of that curriculum in pretty much any business school.
54:17but actually now even in business schools you actually start having more and more business schools or personal finance courses are actually part of the curriculum there as well so and at lbs we also started having one so yeah so that's been a good development interesting yeah we've talked to a lot of john campbell's doing one at harvard james choy at yale anna maria lusardi has one this seems like a lot of people we're talking to are teaching these courses now really interesting what are you most excited about in your research right now everything just kidding but you know so one of the advantages of being an academic is that you know we choose what we work on so we better be excited about it otherwise we chose something wrong so i'm excited about different things so and so for example i have this project that i think is quite cool with pgc of mine oxana smirnova where we we address actually a long-standing problem in household finance which is an empirical problem in household finance which is basically finding out what's kind of the shape of stock market participation over the life cycle or risky share of the life cycle which we would think is kind of one of the basic things we need to kind of get right to get to calibrate the models and figure out what things do but there's some technical problems in estimating these things and so therefore people have struggled with kind of coming up with precise answers and we have sort of a somewhat technical contribution there to kind of address this question that has been there kind of since i started getting interested in this topic so that's quite something quite excited about another one that it's actually quite excited about because maps into this idea we talked about having impact and talking about things that actually matter to people's real lives is not a project with a former phd student of mine nuno clara who's at at Duke University and Michael Botros is actually at Bank of Canada, where we look at simple modifications to student debt contracts and that you can implement, which we find generate welfare gains that are pretty much on par with the welfare gains that you get from the current debt forgiveness proposed by the Biden administration without having any fiscal implication at all, and while actually also reducing default rates on student loans.
56:09So a simple set of modifications that we just proposed, run for the models, look at all the simulation outcomes, do the whole evaluations and come up with that. So that's another one that I'm quite excited about. A few others now. I have two others which are now at the NBR meetings are like the main meetings. So actually right now I have a bunch of stuff going on, which is cool, but it's a little bit overwhelming, but good. Our final question for you, Francisco, how do you define success in your own life? Success in my own life? i guess the same as everybody else you know like being happy whatever whatever happy means you know you kind of have you know family love have great friends have a job that you like and do that i mean that's those are i guess the things you know it's too late to ask for hair so you know so the rest i guess those are i guess it's probably the same for everybody i'd imagine oh it's always a different answer i think that was a good answer though what's the most unusual answer you've gotten?
57:02Oh, geez. The most unusual. One that stood out, I can't remember who gave it to us, but they said that they take stock every day of whether they were happy. So they have like an empirical approach to their own success. I was like, wow, that's impressive. Every day. Wow. Okay. Yeah. That was good. All right. Well, Francisco, this has been a fantastic conversation. We really appreciate you joining us. Thank you very much, guys. I really appreciate the opportunity. This has been great. Really appreciate it.
57:32Thank you.

Household finance has grown considerably as a field of study in recent years. And with the decrease in defined benefits pension plans, households are increasingly needing to take more responsibility for their own financial fates (much more so than they needed to in the past). Joining us today to discuss household finance and the growing importance of households in the economy, is Professor Francisco Gomes. Francisco is a Professor of Finance at London Business School and earned his PhD in economics at Harvard with his main areas of expertise being household finance, capital markets, asset allocation, and macroeconomics. In our expansive conversation with Francisco, we discuss the increasingly important role of households in the economy, how this has contributed to household finance becoming a more prominent field of study, and what can be done to make sure that academic findings reach, and positively impact, households. Francisco shares a detailed outline of what he's learned from his research, covering topics like level of education, automation at work, peer effects, and culture, with explanations of how these elements can impact household financial decisions. We also learn about his passion for financial literacy, why he is such a big proponent of ensuring that everyone has access to a quality personal finance education, and the personal finance course he currently teaches at London Business School. To learn more from Francisco about the study of household finance and how to improve outcomes for households, be sure to tune in today!
