Gita Gopinath on Trade, Currencies, and Economic Transformation

Introduction of Gita Gopinath

0:00Hello, everyone, and welcome back to Conversations with Tyler. Today I'm honored to be speaking with Gita Gopanath, who is Professor of Economics at Harvard,

0:35formerly First Deputy Director at the International Monetary Fund, which is number two in that institution, formerly Chief Economist at the International Monetary Fund, and one of the leading figures in international trade and finance and economics more generally. Gita, welcome. Thank you, Tyler. Thanks so much for having me on your show. Today I have only easy questions. So we're economists, right? Relative prices matter, but it seems that trade balances are fairly weakly correlated with real exchange rates.

1:09How could you explain that?

Trade balances and real exchange rates

1:11Yes. So if you look at what goes into a trade balance equation, it depends upon the relative price of your goods in international markets, but it also depends upon the relative level of demand in the two different countries for just overall consumption. So for example, if in the US consumption is strong, while in China consumption is weak, even if relative prices were to favor, for example,

1:42US goods, just the overall level of demand being lower in China would reduce the overall level of exports from the US to China. So both those variables matter. It's not just the relative price, but also the relative levels of demand in countries. But why doesn't at some point the real exchange rate keep on adjusting so that the substitution effect finally has some importance relative to the income effect? There is this notion that if you were to write an economic model, that our models would predict necessarily

2:16that a country that's running a current account deficit, for instance, would experience a depreciation of their real exchange rate, and a country that's running a current account surplus would experience an appreciation of their real exchange rate. I think that's an incorrect statement. This is the formal statement. It's kind of partly correct, but here's the accurate statement. The only thing our models tell you is, as you know, we have what is a no Ponzi condition, which is some sort of an intertemporal budget constraint. And what it tells you is that a country

2:48that is, for example, running deficits and therefore accumulating a lot of liabilities to the rest of the world will have to repay those liabilities because we have a condition or either way is your default, one of the two. So how do you repay those liabilities? You repay those liabilities in the model. And the equation will tell you that at some point you have to start running trade surpluses to repay those liabilities. You know, assuming you don't have an exorbitant privilege in the sense that what you owe to the rest of the world in terms of interest payments is not always

3:19that much cheaper than what the rest of the world earns from you, right? There are periods in US history when that's been true. That's less true now, and I don't think we can assume that's going forward. So a country that's accumulating a lot of debt to the rest of the world or liabilities to the rest of the world, for instance, will the model will say at some point have to run trade balance surpluses. Now, there are two ways that those trade balance surpluses can come about. One is through a real exchange rate depreciation. So that is true. That could be one channel. But the other channel is if the

3:53country's overall level of demand were to collapse, then that would also mean that they would import less relative to the rest of the world whose demand is higher, and they would import more. So either of those channels or both of those can be in play. And if you look at the evidence in the data, and you try to do some kind of a decomposition of how much of it is, is real exchange rate versus demand, I mean, there is no clear mapping from the fact that if you're a country that's running current account deficits or

4:24running, you know, trade deficits for a long period of time, that you necessarily should see a weakening currency. That puzzles me all the more. So if we think of Australia, which does not have exorbitant privilege, as you know, they ran trade deficits for decades steadily. There was no reason to think Australian demand would suddenly collapse, right? Australia's done fine, has strong fundamentals. Yet the intertemporal constraint on that process, it never seems pushed into the present. Why is the intertemporal constraint so weak? And how should that shape how we think about how economies actually

4:58work? Is everything just flash period by period in like the very simple Keynesian models, or is it something else? Well, it is a constraint that says that if you have net foreign liabilities to the rest of the world, then in a present discounted sense, at some point, you have to be running surpluses to be able to pay that off. That's the only thing that that constraint says. And that can happen through a combination of things. It can happen, you know, either because you have a discovery of a resource that you then export to the rest of the world, and therefore your exports start booming

5:31because of that. Or you have a recession in your country and imports collapse. And the real exchange does play a role. I mean, to be clear, I am not saying that the real exchange rate never comes into play. It does. You have seen countries whose incomes have grown over time have had their real exchange rates appreciated. It just takes a long period of time. And to assume that on a year-to-year basis that if a country is running a trade balance deficit, it should necessarily have a weaker real

6:02exchange rate. I think that making that tight link would be problematic, not just from the theory, both from the theory side and from the empirical side. Now, when exchange rates move, as you well know and have written plenty about, there's very often not that much pass-through to the prices, you know, of imports and exports. And that seems to be another case where relative prices, at least superficially, are not mattering in the way we would expect them to. What's your best

The dominant currency paradigm and trade pass-through

6:28explanation for that? There are important distinctions here. So the question is, what relative prices are we talking about? So there is the question of imports and exports and their link to the relative price of exports and imports. And there you absolutely do have a pass-through and you do have a quantity response. But then when you go to the real exchange rate, which is the nominal exchange rate adjusted by the consumer price indices, those consumer price indices include a whole bunch of stuff that's non-traded, like healthcare, and that is less sensitive to,

7:05you know, an exchange rate movement or to the terms of trade itself. And so therefore, the pass-through to overall consumption from the dual exchange rate can be much more muted as compared to what we see in terms of imports and exports. Now, the work that I did on the dominant currency paradigm was to point out that unlike the typical assumption that was made, which was the Mandel-Fleming-Keynesian-Friedman assumption, that the relative price of your

7:35imports to exports moves, you know, almost one-to-one with your nominal exchange rate. Because the idea is that, okay, I'm the U.S. When I sell to China, I'm pricing my goods in dollars and that dollar price is relatively sticky. When China sells to the U.S., it's pricing goods in the renminbi and that renminbi's price is relatively sticky. And so therefore, when the dollar renminbi price moves around, exchange rate moves around, that causes the relative price of my exports relative to my imports, which is the

8:06terms of trade, to move very much closely with the nominal exchange rate. But if you look at, you know, what the way the world works is that when the U.S. sells to China, it prices its goods in dollars and that dollar price is relatively stable. And when China sells its goods to the U.S., it also prices in dollars. I mean, close to 90 percent of China's exports to the U.S. are priced in dollars and is relatively stable in dollars. So when the renminbi U.S. exchange rate moves around, the relative price

8:37of the terms of trade doesn't move around that much. So that particular channel works differently from the standard theory. Now, I want to be clear that there is still expenditure switching here because unlike the Friedman hypothesis, what you do not have is that when the U.S. dollar, for example, depreciates, that means it's going to reduce imports from China. In the world, the dollar price hasn't changed. That doesn't have much of an effect on imports coming into the U.S. But on the other hand, U.S.'s exports do expand because it's priced in dollars. And in terms of

9:10Chinese renminbi, the costs or the price of that good has gone up. So you get like half of the channel, which is when the dollar depreciates, you don't get the import channel, but you get the export channel. And flipped around from the China perspective, because of this asymmetry, because of the dominance of the dollar, when the renminbi depreciates, they don't really get the big export kick, but they get the adjustment through imports. But say if I look at the Trump tariffs, which you've written on in Journal of Economic Perspectives, there seems to be almost complete pass-through.

9:44That's well described by a simple model of more or less perfect competition. But when we look at exchange rate movements, it's all of a sudden a different model, even though they're both changes in relative prices. And what's the meta model that explains how those two facts fit together? Yeah. So the meta model is, you know, if you look at kind of the simplest story, which I'm going to break down, if you were to think of truly prices are sticky, when China sells to the US, it sets a dollar price, and then the tariff is slapped onto it, then that's just mechanically full pass-through

10:17into the price US importers pay for it, inclusive of tariffs. Of course, that begs the question as to why is it that China is keeping that price in dollars relatively sticky? Sure. And so what we do know is in the case of many countries in the world and many exporters, they also tend to be importers. So the value-added component of trade has declined over time. And because of the dollar's dominant role in the trading system, everybody is pricing their goods to each other in dollars. So in a way, the way you want to think about it is that when China is exporting some

10:52certain goods to the rest of the world, if its imports are priced also in dollars, then those inputs that are going into its production function are priced in dollars and sticky in dollars, you have an incentive to just price in dollars and your dollar price is not going to move that much because the exchange rate adjustment is not doing much, because an important part of your cost of production is also in dollars. So that's the reason why we see a fair amount of dollar pricing in the world. So the sense that somehow China should be able to, or any other country should be able to

11:25cut their dollar prices by a lot when their currency depreciates, is not the case, is because they are also importing inputs from the rest of the world that are priced in dollars, and they don't have that much of margin to squeeze. Now, of course, there's variation across goods. Some goods rely more on inputs that are dollar priced, some depend less. And you do see in the data that that variation matters. So you do see that the pricing behavior is a function of how much do these firms rely on imported inputs. It does seem to me odd that simply the unit of account to some extent determines

11:59whether firms behave competitively or as if they have some market power, right? That goes against all my economic intuitions. And it puzzles me. No, this is not the unit of account, actually. Well, the invoice and currency. Ah, so no. So I would say there's a few things. One is there is the short term, right? I mean, there is the near term when the invoice and currency matters. But, you know, just example I just gave you tells you why people have chosen to invoice in one currency versus another. I mean, the way you think about it is that ideally, if you could flexibly adjust your

12:33price at every instant in time, then obviously an invoice in currency is irrelevant. But companies do sign longer term contracts. So one of the things I looked into when I was doing the research on this was to say, well, if companies are signing long term contracts, this is both about prices and about quantities, right? So it's not just that I sign a contract that says I'm going to sell to you at this per unit price, but it's also that I'm only going to sell X amount of quantity, in which case then these prices are not allocative. But if you look at the contracts, that's actually not the

13:03case. The way it works is that the companies say, we'll sell to you at this price. The quantities, you know, we have a range. Obviously, it's not like we can send you any amount. There was a range of quantities at which we will send to you. So there's that much more flexibility. So there is the short term. And then there is the medium term. But I think what's important to recognize is that the invoicing decision itself is not just some, you know, Calvo Ferry. It's not just some, you know, here we're going to assume we wake up and somebody's told me to price in dollars. There is a reason why

13:34the dollar is used as a pricing currency around the world. And from a pure first principle is kind of not a decision about which currency to invoice in. And there's evidence consistent with that. Now, as you know, the gravity equation is one of the most reliable regularities in international trade economics, that basically the quantity of trade is inversely proportional to distance of countries once you adjust for incomes and some other matters. That seems to be another case where the relative price doesn't matter that much, because few people think the gravity equation is about

14:07transportation costs. Why is it in your view that the gravity equation holds so reliably and so consistently? I'm not an expert on the gravity equation. But I mean, what we do see is, it is the case that physical distance does matter. I mean, there's a reason why trade between the US and Mexico and Canada should be as close as it should be. I mean, setting aside the tariffs that are happening right now. But there's a reason why it makes a lot of sense for countries that are physically closer that this should be the case. Distance does matter. And then over time, obviously, once you build up these

14:42networks and you've built up these relationships, they can persist over time. There are, of course, depending upon the, you can, of course, build pipelines and you can build other kinds of logistical networks to get goods around. But distance does matter. And we also do know that the relative incomes of the countries do matter, too. I mean, there's more trade happening between countries that are large, and that also plays a role. So distance matters because of networks. So if we take US and India, which have pretty strong networks, right? Indians in the United States have earned very

15:13well, started lots of businesses, have tech ties with back home. That then should violate the gravity equation if we consider the networks being strong? I mean, the biggest exports in terms of what it does to the US are service exports, right? Which is the business process outsourcing. I mean, that's the main form of export that happens. And that, of course, is less constrained by physical distance in terms of literally shipping a product across the seas. So again, depending upon the nature of the product that you're exporting, the physical distance may or may not matter that much. I have some Argentina

15:48questions for you. Now, you've worked on Argentina. This is late August 2026. Why is it that right now inflation in Argentina is still so hard to bring down? It seems stuck, right? It's gone down a lot, but it's not obvious there's a lot more further progress to be had easily.

Disinflation and economic policy in Argentina

16:04Yes. I mean, that's actually a lesson we learn every time with countries that are in this disinflation process where you're starting off with inflations of three-digit numbers. Two years ago, I think Argentina's inflation was around 150%. So coming down to 30% is always, I mean, that was tough. Bringing it down is impressive, but it's always the last mile going from here to anything like a single-digit number always takes much, much longer. So this is nothing special about Argentina. Now, in the case of Argentina, what would it take to bring it down

16:39much faster? Firstly, I think there's got to be a lot more confidence in policy continuity. I think what the Millie administration has done very well compared to the previous administrations is recognize that the problem was fiscal, that as long as Argentina was running the kinds of deficits that they were doing and using monetary financing, basically money printing to pay for it, there was no possibility of getting out of this trap. And so he has been running primary supplices since he came

17:10to power. He's absolutely completely committed to it. I mean, I remember our conversations with him when I was at the IMF. This is something he absolutely will not budge from. But Argentina's, you know, there are questions whether the rest of the political class has signed on to this. There's question marks around that. And there are elections coming around. So there was a midterm last year. There is a national election in 2027, October. And it's very reasonable for everybody to pause and

17:42ask the question whether the reforms will continue or will there be a relapse, as we have seen many, many times in the past in Argentina. But say we knew that either he would be reelected or someone similar would be reelected. Would then simple crude monetarism solve the inflation problem if backed by enough will? Or is there still some other thing that makes it hard to bring down the inflation? There is inertia in this process. The good news is that inflation expectations have been trending down in Argentina. So that's great. It's a very high level. I mean, Argentina's inflation was completely

18:16de-anchored at the time when he took over. Any news of the possibility of, you know, the exchange were depreciating even by 1% or 2% would immediately show up in prices. I mean, this was an example of a case where just simply doing a nominal depreciation is not enough. I mean, there were previous governments who were doing nominal depreciations. And in three months, the real exchange was basically back up to where it was before. So there was nothing, nothing changed because it just got priced into goods. So that takes time. How do you, I mean, anchoring inflation expectations is part science, but also

18:51part art. Sticking the course and just showing you're committed to keeping fiscal deficits low, having the central bank be independent, which is another step he's taking right now, which is to have his central bank independence so that there is no monetization of deficits. Argentina will also have to build up foreign exchange reserves, even though the goal is obviously to have a floating exchange rates, but we know that every country pretty much, with the rare exceptions, can have disorderly market conditions. And given Argentina's history with the currency, it will need to build up reserves much

19:27faster than it's doing foreign exchange reserves and what it's doing right now. Also keeping in mind the elections that are coming around next year. In some recent times, it's been quite expensive to fly down to Buenos Aires and buy a good stake because the real exchange rate was kept high. Now that may be a signal of credibility, but many economists criticized that decision, that simply trying to peg exchange rates high has a pretty bad record historically. Was that the correct decision? And has reality vindicated it? Because that semi-peg hasn't really been broken. Besant backed it. At the time, I thought, well, that was

20:01a big American mistake. But that too seems to have worked out okay. What's your view on all of that? So, I mean, I do believe the Argentinian peso needs to adjust more and needs to be allowed to depreciate more than it is doing right now. They have a framework where they moved from an exchange rate, what looked like an exchange rate, peg in previous regimes, to kind of a crawling exchange rate, to now a crawling band. And that band has gotten pretty wide. So, in a sense, their framework should

20:32allow for more movement in the exchange rate. I think they're being far too hesitant in buying dollars to build up their foreign exchange reserves than they should. I mean, I think that's something that they could do much faster because if they did that, yes, they would get some more depreciation, but it would be still, you know, well within the crawling band. So, short answer, I do think that they need to let the nominal exchange rate move. That combined with fiscal policy and monetary policy that doesn't have that depreciation feed directly into prices, that combination will generate some

21:07real exchange rate depreciation. And I think that is valuable for them to do. Now, the thinking behind why do you not want to leave the exchange rate to depreciate more comes from, could make an economic case for that when you say, well, you worry about de-anchored inflation expectations. And so, this is not the world where, you know, our models work. It's kind of a world where when people wake up in the morning, see the newspaper, see that the peso is depreciated, they immediately go on post higher prices, which are even higher than what the depreciation is, because they think this is going

21:41to feed into all the prices that they have to deal with too. So, when you have de-anchored inflation expectations, there is this argument about, okay, we don't want the nominal exchange rate to move around too much. But I think over the past couple of years, thanks to the other policies, inflation expectations have come down, and that should give them some more confidence in letting the exchange rate move around. But a further depreciation is required, and indeed, good. Why isn't the crawling peg just broken now?

22:11It's not that thick and liquid a market, right? There is a wide band right now. So, actually, because the crawl is now tied to inflation from two months ago, it's actually opening and it's getting fairly wide. So, you'd have to do quite a bit of intervention to do something for it to happen. But at the same time, there is a lot of positive about the country. So, you know, there's a lot of reasons to actually want to invest in Argentina and to have a positive view of the country. So, the rest of the fundamentals would be consistent with, you know, attracting money into the country.

22:47And how should they deal with debt deflation issues? So, people in Argentina took out plenty of loans under the expectation inflation would remain pretty high. Now, inflation is much lower. They feel quite pinched. There are also people who vote. What should Malay do? So, yes, the non-performing loans have gone up. What Malay should do is put in place rapidly, you know, a resolution process for these loans, a market-driven resolution process. And as I see it, Argentina is going through a major structural transformation, major one. These will take years,

23:19not months. We would expect to see non-performing loans also because sectors that were previously very protected have now been exposed to much more competition. So, putting in place a resolution process that is market-driven, it's not bailing out banks. I think that would be a mistake. I think that would be helpful. I mean, you do need to deal with it. The idea that somehow you want to prevent this from happening, I think would be problematic. What is needed, and that's the challenge right now for Argentina, is that while inflation has come down to 30 percent, and, you know, it's kind of

23:50interesting. It's one of those countries that understands the second and the third derivative of the price levels very well. And so, they look at what's happening with inflation, and they think, okay, this is pretty good. But what's less good, of course, is what's happening with jobs. And, you know, growth is there, but it's coming mainly from mining and agriculture, and much less from the job-intensive sectors, manufacturing, because they've also been open to competition now. So, there is going to be a difficult transition, and I don't think the government should ignore that.

24:21The idea is to help workers and not necessarily protect the industry. And the more it can do on that front, the better. Should we, as economists, be happy to see stable coins introduced into

Stable coins and the future of currency

24:32Argentina becoming significant, possibly over the longer run, supplementing or even replacing the peso? Is that good, or is it bad? It harms their state capacity too much, or what do you think? So, you know, the way I think about it is that, I mean, some of these innovations serve as a bit of a disciplining device, right? The fact that a country, people in the country have an option to hold their money in more stable forms of currency is a disciplining device on the government and what it can do, and therefore puts pressure on having good policies in the country. Right now,

25:07we know, but do we want to move to a situation where Argentina is dollarized? By the way, that was Millet initially, actually, I mean, he campaigned on the grounds that he was going to have a move to dollarized economy, and he hasn't done that. I would say that I think that's good. I mean, because first of all, there is no panacea in terms of saying this, because you're dollarized, you are safe, or you're a well-managed country. I mean, the two main dollarized economies of the world, Ecuador, El Salvador, are all in programs with the IMF, because ultimately, if you don't have

25:41the right fiscal policies, you're going to end up needing a bailout in any case. So that's not a panacea. And of course, I am of the view that monetary policy is still very valuable for stabilizing economies. And so if you can get the credibility and the central bank independence, then having your own currency gives you much more ability to stabilize your economy. But take, say, the euro area. Both Milton Friedman and Paul Krugman thought the euro was a mistake.

26:12They disagree on many other things. There was a major euro crisis. What did Friedman and Krugman get wrong? If fixed exchange rates aren't so great, why not just let the different European nations have floating rates to some extent? You know, maybe Benelux would be a fixed rate, but the others let them float. Same argument. You know, the origins, as you know this, the origins of the formation of the European Union and then the euro was a political contract. Sure, but we as economists, should we be happy about the euro or regret it? If we say we could ask ourselves the same question

26:44about saying, well, in the U.S., let's take the United States. It's a large country. There's states like California, very, very high income and states that are much less high income. We are part of a currency union. You know, is there an argument to be made that it would be better if everybody didn't have? No. So there is, again, this optimal currency area argument. In the case of Europe, the way I think about it is if they can get increasingly to the goal of actually being truly integrated in terms of their product markets, you know, have much less regulation that

27:18prevents trade across the borders of countries, you know, then in that case, these are the benefits from having that. So at this point, I don't think the debate of whether the euro is useful is really not that important anymore. I think that we are here and there is a lot that can be gained if the European Union and the euro countries were to be truly integrated in the sense of having a lot more trade across the waters, a lot less restrictions. Right now, as we know that there is an issue with

27:49not having enough scale in their companies, all of that can be fixed. So I think that's the more interesting question than whether the euro makes sense. But there's countries that are not on the euro, right? And they face decisions. So Denmark has had a very strict peg, but they don't actually formally use the euro. And that's a choice they face. Iceland faces this choice, Armenia. And we as economists, I would be inclined to tell them, you know, not to enter the euro zone and to stay put. That seems like a pretty important choice. And what would you tell them?

28:19I mean, again, this is very country specific, because there are countries that could gain the credibility by actually tying their hands with their currencies and they get the access to the markets and they get better terms for it. And they get funding from the union. That's been very helpful for a lot of countries to get transfers that helps from their own personal perspective that can be helpful. But if you're a country otherwise that's, you know, well managed, no need for resources from other countries or anything of that kind, then in that case, your flexible exchange rates are helpful.

28:52Now, Scott Sumner argues we shouldn't be worried about trade imbalances at all. We don't worry about them across American states. A lot of the EU has a pretty big current account surplus. Not many people are worried about that. Yet when it comes to China, the talk is all about trade imbalances. And Scott argues that's more of a political project than an actual economic argument. Do you agree with Scott or not?

Evaluating trade imbalances and sector concerns

29:15I would agree with Scott along the following lines, which is that the trade imbalance in and of itself is not something that we should be focused on. I think what we care about is welfare and involves jobs and consumption, what's inflation, purchasing power, and so on. People even wake up in the morning saying, okay, my current account deficit is too big or my current account surplus is too big. I mean, if all of your policies that were delivering good outcomes for your country were to bring along a deficit or a surplus, that's perfectly fine. There are lots of good reasons to be running

29:49deficits and surplus, as we know. There's nothing that tells you that you shouldn't. The problem arises when you have policies that countries have in place that are inconsistent with any kind of a balanced growth model, and they manifest themselves in these trade deficits and surplus. So this is what I'm saying as an economist. Now, of course, from a politician's perspective, there are other arguments for why they would point to it. So what we have seen historically over and over again is that whenever you had these increases in these deficits and

30:24supplices, you've had, you know, trade wars or protectionism, calls for protectionism. That's what happened during Reagan's time, 1980s. That's what led to the Plaza Accord, and then all the adjustments that followed after that. Then you also do worry about the possibility of crises. The great financial crisis was preceded by growing imbalances. And there was a sense in which all these big savings glut, all this money flushing around, all these large surpluses and deficits were part of the problem.

30:55I would say we are now in this third wave of concern about imbalances. So to be clear, it's not the imbalance itself. As an economist, I would say that it's not the imbalance itself. You don't wake up and say, this is what I'm trying to prevent. I'm trying to prevent us from having a deficit. I want us to have balanced trade. I think that's bad economics. But say China is channeling what would have been wage income into investment, and that's plausibly the case. Now, it may be politically unstable in the sense that we Americans object to it. But that's not an argument per se, right? We have a choice as to

31:30whether or not we should object to it. It doesn't seem that rigorous to say, well, this will cause another financial crisis like 2008. There's just not real evidence for that. So Scott Sumner would say, let's just be happy. We have cheaper goods. We send them paper. We get back stuff and go our merry way. And why is that wrong? Okay. So then I would, a few things. So can go into these differences between trade deficits and supplices versus what I would call sectoral imbalances, right? The fact that manufacturing is, China's running a big manufacturing surplus, which is different from

32:04a trade surplus itself, or that it has big EBI production. What we do recognize, again, is that we do a pretty bad job in moving or helping workers that have lost out, have lost their jobs in certain sectors, right? But we're at full employment now. We're very close to it. Yeah. But it's, again, we're at full employment right now, but we've had this period of time when we had communities that were deeply affected by, and not just trade, I mean, automation was a big part of it too. But we don't do

32:38a great job in terms of getting people back into jobs. And that can affect, I mean, depending upon your ideal welfare function for the country, if you care a lot about those people, then obviously in that case, that's something that should matter in your policy decisions. But in the case of China, I mean, I would say firstly, that we are very far in both the case of the US and China, we're very far from the world where countries are doing good policies. And this is all about comparative advantage. And this is all about, this would be the outcome we would have in a world where every country

33:09was doing the right policy. We're very far from that. China's surpluses are a reflection of things going wrong in China. It's not a reflection of strength in China. It's a reflection of weak consumption. It's a reflection of misallocated resources going into different sectors. They did that with their property markets. Now they have a huge property market problem that they haven't been able to fix in five years. They have this now with other markets, including the EVs and other sectors. They have the problem with inflation being too low. You know, they're trying to do so-called

33:41anti-involution policies, bringing companies together and telling them you've got to keep prices higher than what you're doing right now. So this is not the world where we have, you know, the plain good policies. And this is all comparative advantage. And this is the outcome that we see. So I wouldn't push the argument that this is, you know, we should be just happier with cheaper goods from China. Should there be a digital euro? And if so, how do we control or regulate access so there's not too much disintermediation of private sector banking? It seems the more people can use the digital euro,

34:16the more disintermediation you get. If only a few parties can use it, maybe that's fine, but there's hardly any advantage to a digital euro. How do you think about those trade-offs?

Digital money and central bank perspectives

34:25I mean, I have a particular view on the whole discussion on digital money broadly. I mean, in this space, stable coins comes in too, which is the closest to digital money because it's basically backed one-to-one by a fiat currency and can be used for payments, unlike the others. There is the question, do we need this technology? The best argument I've heard from it is that, okay, well, it's going to help cross-border payments because that's where the true frictions are.

34:56And, you know, but if you look at the data in terms of the actual cost of doing a transfer using stable coins, when you include the on-ramping and the off-ramping into fiat currency, it's not clear at all that this is a cheaper way of doing it. Then there is the argument that we need to be able to do 24 hours of banking and we need to tokenize all the assets so that we can move them at fractional amounts at infinite speed. Again, what's the true value of that? It's somewhat

35:27unclear. But there is somehow this sense that we are in this equilibrium. There is private money in the form of private stable coins being coming out. And by the way, one thing I do like about stable coins is that they're finally putting pressure on the banks, on the traditional banks, to actually pay attention to the prices that they charge for their services, especially cross-border. So I love that. That's a good competitive fringe argument for them. But over and above that, what is the benefit of all of this? But it would be weird if money stopped evolving, right? Money evolves over centuries, millennia.

36:01To think that we'll never have digital monies seems highly counterintuitive. And if we're going to have them, shouldn't we have quality ones through central banks, like the European Central Bank, which at least talks about doing it? And thus, we should do it because the alternative is worse. We'll get a worse digital money. Okay. So firstly, Tyler, we have digital money. We're not... All of the banking that happens is based on ledgers and it's all digital. But truly digital programmable money, right? You could do that with the ledgers that exist too. It's not as if the technology doesn't exist. This is

36:32about whether you want to use blockchain technology versus another technology. There are many... We've come so far from using any kind of physical cash. It's all digital right now. But it's also about giving more people direct access to central bank payment systems, right? That's where the disintermediation would come in. Yeah. But the question is that, I'm not sure. I mean, what is the need for that, right? Why do they need to have accounts with the central bank? So if you want to go along and say, okay, well, now it exists, this exists, and should there be central bank digital currencies? I think the concern there is that if you are in a world where it's all privately issued stable coins, and for some

37:09reason, we all gravitate to that world. And at some point, one of the stable coin issuers decides that, well, we're going to not be linked to the dollar, but linked to something else. That's the kind of difficult scenario that one would need to worry about. And then you're saying, okay, well, again, the central bank digital currency works like a competitive fringe and says that we're there, we can step in when there's any misuse of this kind of power that the private firms may have. Again, I mean, there's a reason why central banks everywhere are still scratching their head about

37:41what exactly they should do about this. If you think of the countries that have introduced central bank digital currencies, you think of China, Nigeria has experimented with it. There hasn't been much take up at all. Again, this is August 2026. Some of my friends are quite worried, whether correctly or not, that possibly the marginal buyer for US treasuries today is both private and with some leverage. Some people say, oh, this is UK hedge funds. I don't know if that's true or not. But if I want to set their minds at ease and tell them the treasury market

38:12is going just fine, what argument should I make back to them? Alternatively, you might agree with them. But what's your view? Well, I guess if I were truly trying to be the advocate for saying, don't worry as much about treasuries, I would just say that the alternatives could look worse. I mean, the question is, if you want safe assets, and where would you put it? There is the US, which has the most liquid, largest treasury market. But then if you look outside and you say, you know, one country that looks very, very good is Switzerland, but it is so tiny in terms of

38:42relative scale of its market that you're not going to, you're going to lose money when you put your money in there. The markets are very small. If you get France or Germany or, you know, any other country, Japan, it's not as if you would look around and you'd say that there are great alternatives. But that said, that's if I was trying to make an advocate for the treasury versus others. But I do think there is a problem. We have a problem in America with our fiscal situation, with what's happening with debt, with treasuries. I suspect more and more people are going to go into the short

39:12end in terms of what they hold as opposed to the long end. And you can see that with yield curves going up because it is the case that this isn't, you know, if you look at debt trajectories compared to other countries, including France or Germany or Japan and the others, it's the US debt trajectory going forward that is particularly concerning in addition to what the levels that we're seeing right now. I have another group of friends and they say that AI or artificial general intelligence, it will raise US productivity maybe by half a percentage point a year. This will be like 1995 to 1998.

39:48And the budget won't balance, but debt to GDP will converge at a ratio at something like 100, 120 percent and things will just be fine. Do you agree?

Productivity, AGI, and fiscal trajectories

39:58I mean, if indeed, I think I guess what I would say is that if what you said is true and we do get growth going up persistently by half a percent or so, I mean, yeah, that would absolutely help in terms of the debt to GDP trajectory, just in terms of the math. I think that's very helpful. But do you think it will? At this point, I cannot say that that will necessarily be the case for the following reasons, because even if the technology seems wonderful, I used it a lot, impressed with it. But as you can see, there's a lot of pushback against the use of AI. There's whether there will be widespread adoption

40:30is to be seen. How much more can this technology penetrate, you know, the way it gets used? I think there's question marks around that. And also, we could have a financial market correction that could have, even if the technology is wonderful, as we know that, you could have a correction, which then later on, you could have something better. But you could go through a correction. And in this difficult time, given everything else that's happening in the world economy, I don't know whether we are going to be on this glide path to just having half a percent higher

41:02growth. Now, I have yet another group of friends who think that as AGI approaches, you probably end up with stagflation, because real interest rates are quite high, because the private demand for capital is so extreme. And that may even crowd out government borrowing to some extent. And some people will be losing their jobs. And you end up with pretty high inflation and some degree of unemployment. And that's an altogether new problem for central bankers. Agree or disagree? I don't know. That seems a bit odd. I mean, I would think that if this is going to deliver the

41:33productivity boom... But there's an intermediate period where you get the demand for capital, which right now is very high. But the productivity gains from AI in this moment, we would agree, are quite small. So for a while, you have stagflation, and then a radical deflation later on. So we're talking about now where we could have this period where, with the build-out of all the AI infrastructure, we would get the demand-side effect. And I believe that is correct. I mean, I think that as of now, we are seeing the effect of the build-out of AI, which is more of a demand

42:06story, affecting prices and inflation. And there is. It's not a huge amount, but you're certainly seeing that show up. But you're going to see it increasingly. If the scales of investment that are projected actually materialize, there are some question marks around that too. But yes, in that case, the concern for... If it's a purely demand-driven shock, of course, for central banks, that tends to be an easier problem to manage in the following sense, which is, you know, worse is that there's no trade-off between inflation and output gaps or

42:40inflation and employment. That is true when you have a demand-driven increase in inflation. The concern is if you have a supply shock, then obviously you do have a trade-off in that case. But if it's a demand-driven inflation shock, then, you know, the right thing to do is to tame demand. But we shouldn't see. But it's private sector stimulus, right? It's hard to tame that demand. People want to build all these data centers and compute. And real interest rates are high, and maybe that's bad for borrowing economies. We all know what the Volcker disinflation did to make the third world

43:11debt crisis worse back in the 80s, right? Are we going to see a rerun of that? And then the IMF will just be super busy over the next 10 years? No. So firstly, I think, I mean, I do hear about this fact that AI spend is insensitive to interest rates. I think that is a, you know, on the margin argument. If it turns out, if Kevin Warsh at Jackson Hole were to say that we are going to now start raising interest rates going forward, and that's because we're in an inflationary environment, I bet that that will change if there

43:41will be an effect on AI spend. So I don't think that that's the case. It's a matter of degree of shift that's going to happen. Debt crises and so on. So that's a good question. You know, it's been very interesting because, you know, when I was at the IMF, I spent a lot of time on debt restructuring. You know, the G20 created the common framework, which is basically how do we restructure a country's debt and do that with a platform that brings in official creditors and multilaterals and the private sector and so on together. So, I mean, that seems like an efficient

44:13way to do it. So, yes, so that platform was created, the G20 was created. And I think what has been, you know, very surprising is that we haven't had that many, those many debt crises, despite everything we've seen up and down and sideways in terms of shocks. That does not mean it won't happen. With interest rates going up even more than we've seen, we could see more countries in debt crises. Though I think the new question right now is what is the framework in a world where developed country bond markets are in trouble, real trouble? And I don't think we have

44:48that. And when I see what Secretary Besant is doing, it clearly seems like there's not that framework, but that could be an important area maybe in terms of thinking about, well, what would that look like?

Academic economics and the AI job market

44:59What do you think the future of academic economics looks like if, say, an advanced AI could write a top five paper within two years with maybe modest human assistance, but nonetheless could do most of the hard work? That seems quite plausible today. Have I seen such a paper? I have not. But certainly you can write for third-tier journals today. It's probably doing a lot of that. And again, two years, progress is extremely rapid. Two years ago, you know, it didn't know how many R's were in strawberry, and now they prove math theorems or disprove them. And things like differences and

45:32differences, they're quite automatable. And have the human work for a week and set the agents on the problem and come back with a review of economic studies piece. In fact, do 30 of those a year. Yeah, well, review of economic studies is a top five. But in this case, what I would say is that, you know, as economists, we're a social science. And we've always, for decades, wanted to be associated with the science part of it, because that makes us look more impressive, maybe. But maybe what's going to happen now is that we're going to be associated more with the social side

46:03of the social science. And I see that, I mean, again, we'll see what happens in two years and what the technology can do. But as of now, it's very good at coding. It's very good at once you set up a problem and ask you to solve it. It'll do it very well. But it doesn't have a good sense of what are the right ingredients to throw into the model, because there's no, there's an art to it. And so therefore, I'm waiting to see whether that's the case, whether there is good new insights that can come out of just an AI written paper.

46:38Quite a few of the graduate students, especially from MIT, seem to be taking jobs at Anthropic or maybe OpenAI. What does this tell us about the future of the academic job market? Will there be an increasing brain drain of the smartest people into the private sector, which of course does pay a lot more? Well, I think there are actually two things that are also encouraging that shift, which is the other factor is, you know, what's happening with the funding, what's happening with the National Science Foundation grants, what's happening with the tax on endowments, what's happened, right? And so

47:12that is leading us everywhere, including at Harvard, to hire fewer faculty. So there is less demand, there's going to be less academic positions available because of what we're seeing right now in terms of the policies coming out of this administration. Maybe that's a good thing, who knows? But that's what the facts are. And so that's what the market is. And then on the other hand, you have where the jobs are and where the money is much higher in AI. So I think we're going through this period where, I mean, I can see why more good students and more PhD students and

47:45someone would be looking for jobs in the private sector. And immigration is tougher also, as you must know. But does that mean there's a kind of golden age of academic economics that lies immediately behind us? And now, more or less, for at least for humans, it's just going to get worse? I mean, I think that maybe is my own prognosis. But do you agree? There's one sense in which this feels a bit like the golden age of economics because of the big transformations that are taking place. You know, there's AI, but there's what we just talked about,

48:16the debt markets. There's what's happening with demographics. There's numerous areas where it seems like the whole global economy is churning and shifting. And therefore, I think we all wake up, in a sense, you know, very curious and excited about what we should be trying to help answer. Yes. So it's not, this is not the great moderation period when we were, you know, I think, writing papers on the derivatives. But this is the period where we have big structural changes. So this is a good period. And I think it's the responsibility of everybody, including economists, to engage on

48:50these big, what we're going through in terms of major transformation.

Kerala, politics, and unisex education

48:54Now, you're from a family from Kerala. Why does Kerala keep on electing communists? And how communist are they, really, at this point? It's been a long time, right? Are they just another party, in essence? Or is there something still communistic about them? Yes. So as you know, in every part of the world, what is, you know, whether you're a liberal or not liberal, or whether you're a Democrat or Republican, I mean, that definition of that just adjusts over time. So first of all, in the case of Kerala, with the exception of one election, the government in Kerala has always switched between being communist for one term, and then it goes to

49:30the Congress Party for another term, right? So the label of the Congress Party is, you know, it's Congress Party. It doesn't say it's communist. But if you look at the policies of Congress, they have quite a lot to the left in the state of Kerala. So just to clarify what you said, which is that we do have in Kerala, it switches between the Communist Party and Congress Party, the exception of one election since independence. Why do they tend to be very left leaning? I mean, this goes to the history of Kerala also, in terms of the Maharajas and the way things were done, and the communist levels of education were highest in Kerala for a long period of time. So there are

50:00many factors behind it. And Kerala does benefit from repatriated income from the Middle East, and they get a lot of it, that also helps. But they are moving. I mean, Kerala is actually moving towards doing more and more, you know, encouraging businesses and the private sector and so on. I think they are also moving in that direction. But what they do have is a very large social safety net. And both Kerala and many parts of Sri Lanka, they seem to have much higher social indicators than many other parts of South Asia. There's better rights for women, however imperfect that may be. There's

50:34higher literacy. Public health indicators are much better. Why is that? And since it's Sri Lanka and Kerala, which are, at least in parts, ethnically or culturally similar, it doesn't seem it would be the communist party or some very particular concrete explanation. It seems more general. Oh, that's a good question. And I can tell you what I think, but the honest truth is I haven't exactly investigated this particular question. I just know that in the case of the, you know, the Maharajas of Kerala were very big on educating women. And there's some reason to think that

51:08that filtered through. There's also important large communities in Kerala, which were what I come from, which is matriarchal and not patriarchal, not the head of the family, but in terms of who gets the property, the women and not the men. And I suspect that that plays a role. I mean, because in all of India, it's a patriarchy, except in, you know, some of these communities in Kerala. Though, like you, I would say that it's an imperfect matriarchy. There is still a lot that doesn't really seem

51:40fair to women, but there are some of these unique characteristics about it. And I think, you know, when I was growing up in India, I do remember having a lot of friends who made the point that their parents tried very hard to have a son, while I always grew up with the sense that girls were very important because, again, the matriarchy kind of lineage. And so maybe that plays role too. But I am at this point way outside my area of expertise. But you grew up in Calcutta with a Carolyn family. Is that correct?

52:11I was born there. I was very young when we moved out. What was I? Maybe three years old or four years old or something. And you went to an all-girls Catholic school? Yes. What's your view of unisex education? Do you have one? It worked for you, right? I'm in favor of it. You know, my poor son, I know, I don't know if he was poor, but I was very excited to send him to Roxbury Latin School because it's an all-boys school. And I thought that it was great as an education. But my take on the single-sex one was, it was great because we did everything. Like, there was no roles defined in what girls can do and boys do. You know, when we

52:46put up a play, the girls were in the play, they acted, but they also built the stage. They did it all. And I don't know. I think that's cool. Very last question. Now, your IMF tenure ended in 2025. You're back at Harvard, presumably recovering to some extent. And for your future, what do you plan on doing next, working on next, writing next, researching next? What for you is coming up?

Current research projects and the global economics lab

53:11Thank you. Yeah. No, first of all, I'm really excited to be back and in the thick of all the discussions here. And, you know, given the times that we live in, I think these are very interesting times to be an academic too. And so, yeah, I mean, you know, I'm working on digital money, stable coins, because of my work on dollar dominance. I'm curious to know how this can affect dollar dominance or not. I mean, that's one big area, but also working on a project on AI. What's your AI project? The AI project is, which I've just kickstarted, is actually looking at the impact of AI

53:46on job. Everybody else is doing that. But there is one difference, I think, that's not coming up in the conversations, which is people are tracking what the effect is on what's happening to jobs right now with the advent of AI. But what we've seen through past cycles of automation is that something like 85% of automation-related job losses happen in the first year of recessions. So there's a sense in which there's like a latent buildup of the fact that a pool of workers who,

54:17when there's a recession and you're in cost-cutting mode, companies lay off and then you have jobless recoveries. We saw that after the great financial crisis. So with my co-authors, I am working on trying to understand, to see what we can do right now in terms of tracking what that latent pool could look like. But I'm also interested in AI and financial markets and frictions and so on. And the last thing that I'm doing is I'm launching a global economics lab at Harvard with the mission to help advance an international economic order that benefits people everywhere. I mean, the way I

54:48see it is that we're at obviously a historic time in terms of the global economy, big transformations, shifts of protectionism, geopolitics, AI. And because now economics and politics are kind of getting a bit intertwined, I think it's harder for other institutions and multilateral institutions to be able to do full justice to the big questions that we face. And I think independent researchers have a role to play here. And so that's what I am investing in.
