Climate risk to the financial system

I wrote a piece for Project Syndicate, here,  on climate financial risk.  (This resulted from a presentation on a panel at the NBER summer institute risks of financial institutions meeting, program here. There should be a video version on YouTube but I can't find it. The panel discussion was excellent. You will recognize ideas from my earlier climate finance testimony. I recycle and refine. ) I titled it "an answer in search of a question," but PS didn't like that so we have the "fallacy" title. 

The essay: 

In the United States, the Federal Reserve, the Securities and Exchange Commission, and the Department of the Treasury are gearing up to incorporate climate policy into US financial regulation, following even more audacious steps in Europe. The justification is that “climate risk” poses a danger to the financial system. But that statement is absurd. Financial regulation is being used to smuggle in climate policies that otherwise would be rejected as unpopular or ineffective.  

“Climate” means the probability distribution of the weather – the range of potential weather conditions and events, together with their associated probabilities. “Risk” means the unexpected, not changes that everyone knows are underway. And “systemic financial risk” means the possibility that the entire financial system will melt down, as nearly happened in 2008. It does not mean that someone somewhere might lose money because some asset price falls, though central bankers are swiftly enlarging their purview in that direction. 

In plain language, then, a “climate risk to the financial system” means a sudden, unexpected, large, and widespread change in the probability distribution of the weather, sufficient to cause losses that blow through equity and long-term debt cushions, provoking a system-wide run on short-term debt. This means the five- or at most ten-year horizon over which regulators can begin to assess the risks on financial institutions’ balance sheets. Loans for 2100 have not been made yet.

Such an event lies outside any climate science. Hurricanes, heat waves, droughts, and fires have never come close to causing systemic financial crises, and there is no scientifically validated possibility that their frequency and severity will change so drastically to alter this fact in the next ten years. Our modern, diversified, industrialized, service-oriented economy is not that affected by weather – even by headline-making events. Businesses and people are still moving from the cold Rust Belt to hot and hurricane-prone Texas and Florida. 

If regulators are worried even-handedly about out-of-the-box risks that endanger the financial system, the list should include wars, pandemics, cyberattacks, sovereign-debt crises, political meltdowns, and even asteroid strikes. All but the latter are more likely than climate risk. And if we are worried about flood and fire costs, perhaps we should stop subsidizing building and rebuilding in flood and fire-prone areas. 

Climate regulatory risk is slightly more plausible. Environmental regulators could turn out to be so incompetent that they damage the economy to the point of creating a systemic run. But that scenario seems far-fetched even to me. Again though, if the question is regulatory risk, then even-handed regulators should demand a wider recognition of all political and regulatory risks. Between the Biden administration’s novel interpretations of antitrust law, the previous administration’s trade policies, and the pervasive political desire to “break up big tech,” there is no shortage of regulatory danger.

To be sure, it is not impossible that some terrible climate-related event in the next ten years can provoke a systemic run, though nothing in current science or economics describes such an event. But if that is the fear, the only logical way to protect the financial system is by dramatically raising the amount of equity capital, which protects the financial system against any kind of risk. Risk measurement and technocratic regulation of climate investments, by definition, cannot protect against unknown unknowns or un-modeled “tipping points.” 

What about “transition risks” and “stranded assets?” Won’t oil and coal companies lose value in the shift to low-carbon energy? Indeed they will. But everyone already knows that. Oil and gas companies will lose more value only if the transition comes faster than expected. And legacy fossil-fuel assets are not funded by short-term debt, as mortgages were in 2008, so losses by their stockholders and bondholders do not imperil the financial system. “Financial stability” does not mean that no investor ever loses money.

Moreover, fossil fuels have always been risky. Oil prices turned negative last year, with no broader financial consequences. Coal and its stockholders have already been hammered by climate regulation, with not a hint of financial crisis.  

More broadly, in the history of technological transitions, financial problems have never come from declining industries. The stock-market crash of 2000 was not caused by losses in the typewriter, film, telegraph, and slide-rule industries. It was the slightly-ahead-of-their-time tech companies that went bust. Similarly, the stock-market crash of 1929 was not caused by plummeting demand for horse-drawn carriages. It was the new radio, movie, automobile, and electric appliance industries that collapsed.

If one is worried about the financial risks associated with the energy transition, new astronomically-valued darlings such as Tesla are the danger. The biggest financial danger is a green bubble, fueled as previous booms by government subsidies and central-bank encouragement. Today’s high-fliers are vulnerable to changing political whims and new and better technologies. If regulatory credits dry up or if hydrogen fuel cells displace batteries, Tesla is in trouble. Yet our regulators wish only to encourage investors to pile on. 

Climate financial regulation is an answer in search of a question. The point is to impose a specific set of policies that cannot pass via regular democratic lawmaking or regular environmental rulemaking, which requires at least a pretense of cost-benefit analysis.

These policies include defunding fossil fuels before replacements are in place, and subsidizing battery-powered electric cars, trains, windmills, and photovoltaics – but not nuclear, carbon capture, hydrogen, natural gas, geoengineering, or other promising technologies. But, because financial regulators are not allowed to decide where investment should go and what should be starved of funds, “climate risk to the financial system” is dreamed up and repeated until people believe it, in order to shoehorn these climate policies into financial regulators’ limited legal mandates.

Climate change and financial stability are pressing problems. They require coherent, intelligent, scientifically valid policy responses, and promptly. But climate financial regulation will not help the climate, will further politicize central banks, and will destroy their precious independence, while forcing financial companies to devise absurdly fictitious climate-risk assessments will ruin financial regulation. The next crisis will come from some other source. And our climate-obsessed regulators will once again fail utterly to anticipate it – just as a decade’s worth of stress testers never considered the possibility of a pandemic.

*****

In retrospect I should have emphasized one point more strongly. Suppose you do believe that there is a "climate risk" to the financial system, a "tipping point" that can happen in the next 5-10 years. Suppose you believe that all our forest fires and floods are the result only of climate change, and might engulf the economy in the next decades.  If so, none of the currently advocated policies will do anything about it, especially those implemented by financial regulation.  The best the most aggressive climate policies hope to do is to limit the further increase in temperature by 2100.  Cutting fossil fuels out of debt markets, printing money to buy windmill and electric car bonds, a full on ESG effort in money management ... none of this will lower carbon dioxide to pre-industrial levels in the next 10 years. None of this will stop wildfires and floods in your great-grandchildren's lifetimes. 

It follows, that if financial regulators accept even the most climate-alarmist position, and for the goal of protecting the financial system, the policy must be one of rapid adaptation. Spend billions to clear the brush that burns, to build dikes, and certainly not to rebuild crumbling condos on the sea shore.  The mantra (I listen to NPR) that each disaster is the result of climate change does not mean that any currently envisioned climate policy is the best, or even vaguely effective, way to combat the chance of such disasters in our lifetimes. Or those of our great-grandchildren. 

That simple fact does not mean we should ignore the climate, but it does mean that if you truly believe these scenarios, an immense adaptation effort must be undertaken right now. If you don't follow to that conclusion, perhaps you don't really believe that there is a climate financial risk, and this is just a subterfuge to pass policies actually aimed at year 2100 temperatures and having nothing to do with climate risks, by radically un-democratic means. Which is my point.

Rossi-Hansberg on the effects of a carbon tax

I was inspired to think again about climate economics from Esteban Rossi-Habnsberg's excellent presentation at the  Hoover Economic Policy Working Group. Link here in case the above embed does not work. Paper here, (with Jose Luis Cruz Alvarez), slides here. Previous introductory post here. 

There is a lot in this paper and presentation, and I'm going to try to stick to one topic per post. 

Like most economists, my knee jerk reaction to climate change is "carbon tax." In particular, a carbon tax instead of extensive regulation. Given that we're going to have a climate policy that discourages carbon emissions, a uniform price on carbon emissions is the only sensible and effective way to do it. (Whether tax, tradeable rights, or other mechanism doesn't matter for this purpose.) I would add remove barriers to alternatives, such as nuclear power, and a healthy expenditure on basic science of alternatives. 

With that in mind, I was stunned by these graphs:



Carbon taxes do not stop climate change. They just postpone it. They do postpone it substantially. In the bottom graph, we get 4 degrees rather than 6 by 2100. But still, we're at the same place by 2300.

How much does climate change actually affect GDP? Part I: An illogical question.

How much does climate change* actually affect GDP? How much will currently-envisioned climate policies reduce that damage, and thereby raise GDP? As we prepare to spend trillions and trillions of dollars on climate change, this certainly seems like the important question that economists should have good answers for. I'm looking in to what anyone actually knows about these questions. The answer is surprisingly little, and it seems a ripe area for research. This post begins a series.  

I haven't gotten deep in this issue before, because of a set of overriding facts and logical problems. I don't see how these will change, but the question frames my investigation. 

An illogical question

The economic effects of climate change are dwarfed by growth

Take even worst-case estimates that climate change will lower GDP by 5-10% in the year 2100. Compared to growth, that's couch change. At our current tragically low 2% per year, without even compounding (or in logs), GDP in 2100 will be 160% greater than now. Climate change will make 2100 be as terrible as... 2095 would otherwise be.  If we could boost growth to 3% per year, GDP in 2100 will be 240% greater than now, an extra 80 percentage points.  8% in 80 years is one tenth of a percent per year growth. That's tiny.  

In the 72 years since 1947, US GDP per capita grew from $14,000 to $57,000 in real terms, a 400% increase, and real GDP itself grew from $2,027 T to $19,086 T, a 900% increase. Just returning to the 1945-2000 growth rate would dwarf the effects of climate change and the GDP-increasing effects of climate policy. 

Comparing the US and Europe, Europe is about 40% below the US in GDP Per Capita, and the the US is about 60% above Europe. So Europe's institutions do on the order of 5-10 times more damage to GDP than climate change.    

Residential zoning alone costs something like 10-20% of GDP, by keeping people away from high productivity jobs. Abandoning migration restrictions could as much as double world GDP (also here). 

It is often said that climate change will hit different countries differentially, and poor countries more, so it's an "equity" issue as much as a rich-country GDP issue. Yet just since 1990, China's GDP Per Capita has grown 1,100%, from $729 to $8405 (World bank). As the world got hotter. 1,100% is a lot more than 10%. We'll look at poor country GDP climate effects, but from what I've seen so far, reducing carbon doesn't get 1,100% gains.

Lessons learned? Review of a great review.

After great events, will the US government and political system learn from mistakes? Or will we raise the bridges and enshrine whatever was done last time as holy writ, to be repeated again? Reputations of people in power push for the latter. But learning from mistakes is the only way to get ahead. 

Bailouts and stimulus from 2008 seem to have followed the latter possibility. Will the lesson from covid look skeptically on the disastrous performance of CDC and FDA, evaluate whether lockdowns did good commensurate with cost, question the need to spread trillions of newly printed money around, measure the  effectiveness of masks that have now become political symbols? Or will this simply be enshrined as the playbook? Do we twist every event to push our partisan narratives, facts be damned? A blame-Trump-for-everything camp offers some hope, but they're not clear what they would do differently as most of the world's response was the same or less effective than our own. 

This big question frames a must-read Alex Tabarrok Marginal Revolution review of Andy Slavitt’s Preventable. The review doesn't just destroy an otherwise forgettable book, but it really raises these larger questions whether we are so politically polarized that we can no longer learn from mistakes. 

In contemporary discussion, people can just say things that are blatantly untrue, and it all washes over us. 

The standard narrative ... leads Slavitt to make blanket assertions—the kind that everyone of a certain type knows to be true–but in fact are false. He writes, for example:

In comparison to most of these other countries, the American public was impatient, untrusting, and unaccustomed to sacrificing individual rights for the public good. (p. 65)

Data from the Oxford Coronavirus Government Response Tracker (OxCGRT) show that the US “sacrifice” as measured by the stringency of the COVID policy response–school closures; workplace closures; restrictions on public gatherings; restrictions on internal movements; mask requirements; testing requirements and so forth–was well within the European and Canadian average.

The pandemic and the lockdowns split Americans from their friends and families. Birthdays, anniversaries, even funerals were relegated to Zoom. Jobs and businesses were lost in the millions. Children couldn’t see their friends or even play in the park. Churches and bars were shuttered. Music was silenced. Americans sacrificed plenty.

... Some of Slavitt’s assertions are absurd.

The U.S. response to the pandemic differed from the response in other parts of the world largely in the degree to which the government was reluctant to interfere with our system of laissez-faire capitalism…

Laissez-faire capitalism??! Political hyperbole paired with lazy writing. It would be laughable except for the fact that such hyperbole biases our thinking. 

I think the problem is deeper. It's not that this is "hyperbole." It's that this is the sort of mushy sentiment that one can pass around at Washington cocktail parties as easily as write on the front pages of all major media these days, and everyone says yes, sure, without batting an eyelash. It's not hyperbole, it is the unquestioned narrative, it's an inshallah people can add to any statement without question. That's the true danger.

Fast grants and the economics of subsidizing science

One of the great insights of modern growth theory -- Paul Romer's Nobel Prize -- is that ideas are the foundation of economic growth. Ideas are also "nonrivial." If you use my car, I can't use it, but if you use our family recipe for road-oil chocolate cake (yum), we can still enjoy it as much as ever. Once an idea has been had, economics says it should be used as widely as possible as soon as possible  

But coming up with ideas is expensive. And aside patent protections, I can't charge for the benefit to you of my new ideas.  So, economists naturally notice the mother of all public goods. Research -- finding new ideas --  has enormous benefits, and people will not naturally devote enough resources to finding, refining, implementing new ideas. So, economists conclude,  the government should subsidize idea-production. 

But which ideas?  Now we face the conundrum. It's just as easy to subsidize bad idea production as good idea production, and it's even easier to waste money and produce no new ideas at all. How to subsidize actual productive ideas is a hard question of bureaucratic structure. The economics of science is, I think, vastly understudied. How can government agencies or philanthropies give away money and actually do good? This topic is especially relevant as we contemplate a big ramp-up in federal spending. 

Enter today's topic, a fascinating review of Fast Grants by Patrick Collison, Tyler Cowen, and Patrick Hsu.  Read first the Marginal Revolution summary, then the full article

I found it as interesting for its insights into the pathologies of our current system for subsidizing research as for its summary of how well fast grants worked. 

They survey fast grant recipients. Despite being in an evident crisis, and $5 trillion being shoveled out the door... 

64% of respondents told us that the work in question wouldn’t have happened without receiving a Fast Grant.

For example, SalivaDirect, the highly successful spit test from Yale University, was not able to get timely funding from its own School of Public Health, even though Yale has an endowment of over $30 billion. Fast Grants also made numerous grants to UC Berkeley researchers, and the UC Berkeley press office itself reported in May 2020: “One notably absent funder, however, is the federal government. While federal agencies have announced that researchers can apply to repurpose existing funds toward Covid-19 research and have promised new emergency funds to projects focused on the pandemic, disbursement has been painfully slow. …Despite many UC Berkeley proposals submitted to the National Institutes of Health since the pandemic began, none have been granted.” [Emphasis ours.]

Even Finance Professors Lean Left

You may have thought of finance professors at business schools as likely to be a fairly conservative lot, or at least to include a good number of them. You might think finance would be an exception to the growing political monoculture in US academia. You would be mostly wrong.  

Emre Kuvvet tracked down the party affiliation of finance professors in the top 20 US departments, and wrote up the results in "Even Finance Professors Lean Left


Berkeley has more Republicans than Chicago? I think numbers are low because so many faculty are not US citizens. It's initially striking  how many finance faculty are not even registered to vote, but I suspect that this reflects the large number of non-US citizens in finance departments. 


Here come the millennials... Or, maybe Churchill was right about hearts and brains. 

Journal editors: 

Not even the JFE can manifest many Republicans! 

Of course this is a striking amount of political diversity by the standards of the rest of most universities.

Garicano's conversations with economists


Luis Garicano has just posted a very interesting free e-book, "Capitalism after covid: Conversations with 21 economists." I was honored to be one of his interviewees, video here. Luis has a VoxEU column summarizing conversations, and twitter thread if you like reading such things. Luis is a great interviewer. 

This is not an endorsement of all the ideas! Luis found a wide spectrum of ideas, and I think that is the strong thing about the project. You can see how really smart people, on top of the latest academic research, come to still widely different conclusions about the current state of affairs and directions we should go. Though Luis is a pretty free-market Chicago guy, he did not impose that view which I find admirable. 

In particular, referring to the VoxEU column, I would take issue with 

The bulk of the shock was absorbed by the public sector budget. 

That the world could produce such a massive, coherent, and rapid economic response to the pandemic had a lot to do with the consensus that quickly emerged among economists on how best to respond to the unprecedented shock...

Unlike during the Great Financial Crisis, when there was an often-acrimonious debate between economists arguing for austerity and those arguing for stimulus, the priorities were clear: 

Central banks should be concerned with maintaining financial stability and providing limitless liquidity to debt markets. 

Governments should prioritise the maintenance of household incomes through generous support for workers’ incomes, albeit with different approaches in the US and Europe: significant expansions of unemployment insurance in the US and the general deployment of ‘Kurzarbeit’ in Europe.  

Governments should provide ample liquidity facilities to firms, making it possible for them to emerge as undamaged as possible by the lockdowns. 

Finally, large, debt-financed public investments would be needed to support the recovery. 

I  disagree loudly with just about all of this, and thereby especially enshrining these expedients as "consensus" ready to be deployed at even larger scale in the next pandemic. 

If there is consensus on anything it is that our governments completely bungled the public health aspect of this crisis, with the exception of a few countries like South Korea and Taiwan. The FDA and CDC are particularly at fault for blocking testing and vaccines. 

Why did covid produce an unprecedented economic collapse, while the 1958 and 1918 flus produced nary a blip of GDP? Because of the completely overdone business lockdowns. The economic shock was caused by the government not by the virus. What good did it do to run up government debts by trillions in order to send checks to retirees and people who were happily working? I'm sure everyone likes more money, but that has nothing to do with covid. Apparently half of expanded unemployment was stolen (I even got notice someone trying to file in my name). " large, debt-financed public investments would be needed to support the recovery." Consensus on that please? Not from here. The recovery is doing fine on its own, and adding more to the abstract sculpture taking place in the Central Valley under the auspices of a high speed train from Bakersfield to Modesto is not going to help. And why is nobody even thinking moral hazard? We now have enshrined a system in which nobody may lose money in a recession, asset prices will be propped up by central banks. Why not lever to the hilt? Why keep some cash around, as there will be no more buying opportunities? 

But that Luis interviews such good and prominent economists and finds support for this sort of boondoggle policy is interesting. 

Tackling inequality. Over the last few decades, inequality in household income and wealth has increased dramatically in the West.  

This is simply not a fact. (See Grumpy coverage of Austen and Spinter here.) Inequality in pre-tax pre-transfer income has increased. Who cares about that? Inequality of mark-to-market wealth has increased as founders stock values have risen. Who cares about that? 

Several interviewees explain the progress economists are making in tackling these problems. Atif Mian argues that to reduce inequality, policies must focus on achieving more equitable growth through a significant increase in public investment, and second, on addressing some of the legacies of the imbalances, particularly through an increase in the progressivity of taxation. 

Well, if you are a grumpy follower you will find there a well articulated points to disagree with. The US already has the most progressive tax system in the world BTW. And back to more high speed trains to nowhere.. 

Stefanie Stantcheva discusses how to design better taxes and how to improve people´s understanding of those issues. Oriana Bandiera highlights a significant shift in our understanding of poverty that implies that social assistance programmes, that traditionally were designed to subsidise consumption, should shift to being geared towards investment. Esteban Rossi-Hansberg discusses the concentration of talent and economic activity in cities and the extent to which the ‘Zoom revolution’ will upend this concentration and wonders whether that would be desirable, given the potential loss of positive externalities of physical proximity.

But here are some good-sounding innovative ideas, to give you a sense that economists don't just line up on typical left-right spectrum. I need to read those. 

Containing the new leviathan.  It is quite likely that, after the unprecedented policy response to the pandemic, governments will grow permanently larger, leading to an increase in interventionism and, potentially, crony capitalism, as Daron Acemoglu argues. Different countries will sharply diverge in their response to this “critical juncture”. The ones who better succeed will introduce stronger democratic institutions to keep governments in check, as both Acemoglu and Lucrezia Reichlin argue. We also need to improve the way public organisations are managed, a focus of the interviews with Raffaela Sadun and Carol Propper.  Wendy Carlin explains how balancing this larger role for the state requires building a stronger and more resilient civil society – strengthening the ‘third pole’.

This all sounds really interesting. Economics and economists are most interesting when out of the political boxes! 

Tackling climate change. ... Reducing carbon emissions, as Michael Greenstone explains in his interview, must be the only priority – not to be confused with delivering the goodies to voters. 

Voters and interest groups. Mother Gaia does not care if the electric car charging stations and solar panels are made in the US by union members or made in China at a tenth of the cost. 

Yet, after the pandemic, as Nick Stern argues, investing in tackling climate change is the best way to invest for the post-pandemic recovery. 

I will not pre-judge, but if this is more broken windows fallacies and create more jobs by using spoons not shovels, I will be skeptical. 

In sum, this looks interesting throughout and a good view into the spectrum of analysis that economists are bringing to contemporary issues.

Meritocracy

Adrian Woolridge wrote a thought-provoking essay titled "Meritocracy, Not Democracy, Is the Golden Ticket to Growth," advertising a forthcoming book. 

Meritocracy, the secret sauce of growth?  

To Woolridge, meritocracy is the secret sauce of prosperity: 

The surest sign that a country will be economically successful is not the health of its democracy, as some liberals like to think, or the leanness of its government, as some free-marketers imagine, but its commitment to meritocracy. Singapore is a soft authoritarian power. But it has transformed itself in a few decades from a poverty-stricken swamp into one of the world’s most prosperous countries, with a higher standard of living and a longer life expectancy than its old colonial master, because it is perhaps the world’s leading practitioner of meritocracy. The Scandinavian countries have some of the world’s largest governments and most generous welfare states. But they retain their positions at the top of international league tables of prosperity and productivity in large part because they are committed to high-quality education, good government and, beneath their communitarian veneer, competition; in other words — meritocracy.

By contrast, countries that have resisted meritocracy have either stagnated or hit their growth limits. Greece, a byword for nepotism and “clientelism” (using public-sector jobs to reward partisan cronies), has struggled for decades. Italy, the homeland of nepotismo, enjoyed a postwar boom like France and Germany but has been stagnating since the mid-1990s....

Democracy alone does not lead to growth, and likewise growth does not swiftly lead to democracy. Look at China vs. India, and many democratic, at least in the sense of leaders chosen by fairly free elections,  but poor countries around the world.

For a generation, political economists have been looking more deeply at institutions -- rule of law, property rights, etc. -- as a secret sauce. "Meritocracy" is a good buzzword for a different idea of what is centrally important. 

...countries that favor recruiting professional managers through open competition have higher growth rates than those that favor recruiting amateur managers through personal connections. America has the highest overall management score, followed by Germany and Japan. Rich-world laggards such as Portugal and Greece, and big emerging-market countries such as India, have a long tail of un-meritocratic and therefore badly managed firms.

The essay goes on, condensing much more evidence. 

It is plausible that meritocracy is especially important now, as businesses globalize and incorporate IT. The rising skill premium and larger reach of global corporations means that it is ever more important to match skilled people with the positions that require skill.

 His bottom line 

... The idea that there is a necessary relationship between democracy and growth rests on a false positive. The really robust relationship is between meritocracy and growth. ..

the evidence of economics is overwhelming: Meritocracy promotes prosperity, and dismantling meritocracy will reduce it. Those who support the current campaign against merit need to admit that they are opting for lower growth. 

I am not an expert on the huge political/economic literature on the correlates of growth. This sounds reasonable, but the Acemoglus, Barros, etc. of the world may have important things to say on the evidence. Still, it's a novel idea and let's follow it.

Vaccine slowdown?

 


Source. Everyone seems tired of covid. And sure, inflation, debts, "infrastructure," competing voting narratives and so on are more fun. But covid is still with us. 

The graph summarizes what I've read in lots of news stories: vaccination is slowing down. There is plenty of supply, but we are running in to people who do not go get the vaccine. 

This strikes me as a tragedy. (Disclaimer: this is an exploratory post, and I'm anxious to hear about it from more knowledgeable people). It means covid will remain with us as an endemic disease, occasionally breaking out as immunity fades and covid evolves. We're on the 20 yard line, folks, it's not time to punt.

I'm pretty darn libertarian, but not about vaccinations. The US should be pushing for near universal vaccination. This is like finishing your dose of antibiotics. 

We do not have to jump to compulsion. Can we at least allow incentives? Vaccine passports sound like a no-brainer even to a libertarian. Allow me to disclose that I am vaccinated, and allow owners of private property like restaurants, bars, airlines, and so forth to demand proof of vaccination. That provides a nice incentive for people to get vaccinated. 

Our policy makers seem so completely deranged by the tiniest "equity" concerns that even this simple step is off the table. On NPR the fact that some disadvantaged groups refuse the vaccine means the rest of us can't have passports. Republicans are also refusing the vaccine, and nobody cares about that! Yes, some immunocompromised people can't get vaccines. Well, on that altar are we going to allow everyone else off the hook, or push to get others vaccinated so they don't infect immunocompromised people -- who shouldn't be going to bars anyway. This debate goes on and on, and time is wasting. 

Even the public messaging has faded away. Our nudgers in chief should be nudging like crazy -- go get vaccinated, people! 

 


I think my best moment as a blogger last year may have been my SIR model with behavior  that predicted the reproduction rate would settle down near one. When it's larger than one, people are more careful, including getting the vaccine. When it's less than one, people slack off. We are seeing a massive case of people, and politicians, slacking off of the one most important step, full vaccination. 

Eurosclerosis update

 


All pre-covid. European GDP per capita fell in the decade following the financial crisis. US growth was nothing to write home about, but things could be worse. The we-should-be-more-like-Europe crowd has some explaining to do. (The Word Bank's software misplaced the UK label; it is the red line on the top of the European group.) From the World Bank, HT Marginal Revolution.

The graph is in dollars, so part of the effect is that the dollar got more valuable relative to the euro. (Thanks to the commenters who noticed that I misread the graph caption. Blog post now fixed to reflect that.) 

Update

A correspondent sends along the following graph from IMF data. IMF data uses PPP adjustments, not straight conversion to dollars. So the exchange rate really is an issue in comparing US to EU growth.  


Relative inflation has not been that different between the two countries. 


At least by these measures, EU inflation has been only very slightly less than US inflation 

So indeed, the exchange rate is the major part of the difference between the two graphs. Whether PPP or actual exchange rates are "right" for this purpose I leave for another day. Certainly the average American's ability to buy European goods has risen relative to the average European's ability to buy American goods. Why exchange rates diverge so long from PPP measures remains, I think, a central puzzle. But thanks to blog readers for quickly pointing out that the Marginal Revolution graph isn't as immediately relevant as it seemed.

Whither the Fed

I gave the UCSD economic roundtable lecture Friday June 11 on inflation and the future of the Fed. It summarizes quickly a number of themes from previous Grumpy writings, and if you enjoy videos you might find it fun. Youtube link in case the above embed does not work. 

I happened on the New York Fed website, proclaiming on its landing page that it is now

"...dedicated to understanding and finding solutions to the numerous forms of inequality that communities of color experience and working with communities in our District to address deep-seated inequities," 

in case you want documentation that the Federal Reserve is taking on inequality and racial issues.

The end of "the end of inflation"

This spring's spurt of inflation clearly already means one thing: The end of "the end of inflation." 

For 25 years inflation has seemed stuck on a downward trend. Those of us who worry about it seemed like end-of-the-world sign-holders that couldn't leave the 1970s behind. It's hard to buck the trend. A famous economist advised me to give up studying inflation -- inflation is 2%, he said, that's all you need to know. Apparently a new constant of nature. 

Well, apparently not. Inflation can happen, and there is an economics of inflation. Right now it's pretty obvious -- supply constraints both natural and artificial, coupled with rampant demand. 

Nobody is really sure where it will go. See the IGM survey for a good indication of how wide sensible consensus is on the issue. Maybe these are just temporary shocks, supply bottlenecks, a one-time price level rise from stimulus. Maybe it is the beginning of the 1970s, when exactly the same excuses were offered. 

I'll summarize my bottom line in thinking about this issue. 

1) The dynamics of inflation are roughly     

    inflation = expected inflation + inflation pressure   (*)

If people expect higher inflation next year, then sellers will be quicker to raise prices, and buyers quicker to pay higher prices.  The right measure of inflation pressure is more contentious. The unemployment rate or GDP gap (you will recognize a Phillips curve here) has been a pretty terrible measure. Take your pick of too-low interest rates set by the Fed, too much money, or too much debt and deficit. Whichever it is, if expected inflation remains "anchored," inflation comes back quickly once the pressure is off. If not, we're  in trouble as we have to bottle the expected inflation genie. 

The Fed seems to think that "anchoring" expectations comes from soothing speeches about how anchored expectations are. At worst they may say they have "the tools" to contain inflation should it break out, but they seldom say just what those tools are. I believe that expectations come from expected actions, not speeches, and better from robust institutional rules and commitments that force necessary but unpleasant actions when needed. At least, people must believe that the Fed is willing to repeat 1980 if it comes to that.  And raising interest rates will be much harder now, with a) 100% debt / GDP not 25%, so higher interest rates immediately hurt the budget b) huge reserves so the Fed will be seen to pay a windfall to big banks not to lend out money c) the too-big-to-fail banks will all lose a bundle if interest rates rise d) the current emphasis on inequality, as a recession will hurt the most vulnerable the most. 

2) In today's economy, in the end, inflation comes when people do not believe the government will repay debt. Beyond interest rates, the Fed changes the composition of government debt -- reserves vs. treasurys -- but not the amount of debt. Whether we hold treasurys via the world's largest money market fund (that's what the Fed is) or directly really does not matter. 

Inflation does not come from debt alone, but from debt relative to a credible plan and expectation that debt will be repaid. Expected inflation is anchored by the belief that  if inflation gets out of control our government will promptly put its fiscal as well as monetary house in order. Moreover, since our government has tragically borrowed short term, inflation comes when people believe that other people will lose this faith. Putting the fiscal house in order is not hard as a matter of economics -- a straightforward pro-growth reform of the tax code and entitlements. But our government has kicked that can down the road for nearly 40 years, and absolutely nobody wants to do it. It may have to come after the crisis, which will be much harder. 

None of this is very useful as a short-term forecast, which I do not offer. Both fiscal and monetary policy expectations, in this "regime-switching" moment, are volatile, not well anchored by decades of experience with a "regime," in the rational expectations tradition. I can offer then a summary of the forces at work, but those forces only emphasize how hard forecasting will be. If anyone could tell you for sure we would have inflation next year, we would already have inflation today. The logic of (*) is like the logic of a bank run or a stock market crash. That nobody can predict inflation well is proof of the theory. 

This spurt may pass, and expected inflation, reflecting faith in the ultimate sanity of US fiscal and monetary policy, remain anchored. This spurt may lead to a quick undermining of that faith. 

But at least the question is alive again, and a matter of useful economic analysis and debate. This for sure: The end of "the end of inflation" is at hand. 

Update: There is a slightly condensed and cleaned up version of this post at the Chicago Booth Review




Why won't banks take your money?

 Banks to Companies: No More Deposits, Please, says the puzzling headline at WSJ. 

Why would bankers not want to take any amount of deposits, park them in reserves at the Fed or short term Treasury bills, charge fees and a slight interest spread, and sign up for an early tee-time at the local golf club? Sure "net interest margin" or other metrics might not look good, but money is money and more money is more money. 

The answer: 

Top of mind for many big banks is a rule requiring them to hold [sic] capital equivalent to at least 3% of all assets. Worried about the rule’s impact during the pandemic, the Fed changed the calculation in 2020 to ignore deposits the banks held at the central bank, but ended that break this March. Since then, some banks have warned the growing deposits could force them to raise more capital, or say no to deposits.

This is a fascinating little insight into the crazy world of our Fed's risk regulation. 

Three inflations

 The latest inflation numbers are out, up 0.64% from April to May (7.7% annualized), on top of 0.77% (9.2% annualized) from March to April. . To get around the base controversy, I like to plot the level of the CPI: 


The graph suggests that  "reflation" from the pandemic recession was over last year, we had been back to the usual growth, and now we're embarked on something new. 

Inflation is not the same everywhere. For another purpose I broke inflation down to durable goods and services. 


Until about 1985, the three categories moved together. After that we saw a sharp divergence. Inflation depends on what you buy. Services got much more expensive, while durable goods actually saw deflation. The forces are familiar. The rise in skill premium has meant that people got more expensive, and some of that reflects also the rise in cost of businesses such as health care and universities which may have more to do with government payment. Durable goods got cheaper, thank you China, but also they got a lot better and the CPI decline reflects quality adjustments rather than lower sticker prices. (Nondurables and housing behave a lot like the average, so I don't show them.) 

Not all inflation is the same, and what you experience depends on what you buy and where you buy it. 


Now to the point: Where is the current surge in inflation coming from? I rebased the CPIs to 2018, and here they are. No surprise, the current surge of inflation is concentrated in durables.  Durables went up 3% April to May, a 36% annualized rate, on top of 3.52% March to April!  The others are rising too, interestingly, but not as spectacularly. It's also interesting that the big decline in the pandemic was among nondurables. This is all common sense. Bar and restaurant prices went down in the pandemic, less so TVs and gym equipment, and "stuff" is now really getting hard to find and to produce. 

As Tyler Goodspeed points out, this inflation has wiped out the real value of recent nominal wage gains.

(For analysis, the "inflation" tag has several recent posts on the topic.)

What about Japan?

What about Japan? It's a question I often hear from advocates of fiscal expansion. Japan has huge debts and no crisis or inflation (so far). Doesn't that prove the US can borrow a ton more money painlessly? 

I offer two new points today: 1) Not every high debt country is so happy. 2) Just what did Japan get for all its fiscal stimulus? Indeed, I will start asking "What about Japan?" Japan seems a tough case for those who advocate that fiscal stimulus will save us from secular stagnation, or that huge spending programs bring prosperity in other dimensions.   

1. Picking and choosing

Here, fresh from the April IMF Fiscal Monitor  is the list of top 30 countries sorted by debt to GDP ratios. I boldfaced larger countries. 


Yes, Japan is up there at 256% of GDP. The champion is Venezuela however. Sudan and Eritrea are not particularly known for economic prosperity. Greece and Italy are not held up as examples to follow either. Serial defaulter Argentina is behind the US already. 

If Japan is sustainable, that doesn't mean all large debts are sustainable. It means there's something different about Japan than the other countries on the list -- or ones now lower down on the list because they already defaulted or had crises. 

2. So what did Japan get for all that debt anyway? 


It was not always thus. Japan started borrowing heavily in the 1990s from a debt/GDP ratio of 63%. (For some reason the IMF does not have US data before 2002.) 



Those debts come from deficits, of 5-10% of GDP every year. Since 2006, the US has been behaving a lot like Japan, or more so. We only have less debt because the US ran surpluses through the 1990s. 

Japan has had perpetually low GDP growth, low inflation and zero interest rates since the 1990s. I view it as low "supply" growth, but it ought to be the poster child for "secular stagnation" fans. 

So I turn the question around: If massive deficits, including lots of "infrastructure"  are going to boost the US economy, why did they not do so for Japan? 

Update

In response to tweets about why is Japan different from the US,  

I did not want to repeat old points. Japan's debt is long-term, held by domestic people, pensions and central bank. US debt is short-term, held by foreign central banks and financial institutions. Our debt is much more prone to run, and a rise in interest rates will feed quickly into the budget. Japan also has accumulated assets from trade surpluses; we have the opposite. Japan's debt is held by old people and subject to estate tax. A lot of Japanese hold bank accounts, as mutual funds and similar investment vehicles familiar in the US are less prevalent. Bank accounts flow in to reserves, backed by Treasury debt. 

More importantly, Japan  does not have looming unfunded Social Security and Medicare, underfunded pensions, contingent liabilities (Fannie and Freddy guarantee most home mortgages, who is going to pay student loans?) bailout guarantees and more.

 Sustainability is about debt vs. ability to repay; about future deficits;  not debt alone.

Japan's slow growth for three decades comes from microeconomics, taxes, regulations, demographics, slow productivity, not money, stimulus, "aggregate demand."

Proxies

A correspondent asked for comment on the new ESG trend among asset managers. For example, BlackRock, and the recent Exxon upheaval with two new green directors (here, but cautionary WSJ coverage here, pointing out how empty the whole Exxon affair really is).  I'm sad to see even Vanguard (which has a lot of my money) going along on this...trend. 

Could you offer some thoughts about the trend of asset managers voting more critically this year? Are the big fund firms like BlackRock getting too far removed from the wishes of their customers? Other analysts say that BlackRock and other ESG-minded fund firms are only following the wishes of their younger investors who care more about those themes, maybe that makes it all ok?

My answer: 

As a private property fan, if the owners of a company want to spend its money on pointless virtue signaling, or important but unprofitable save-the-planet and cure-racial-injustice initiatives (depending on your point of view),  that’s up to them. I would rather get rid of the whole corrupt non-profit status anyway and see lots of organizations organized as corporations devoted to causes right and left. 

The issue here is representation. A very small minority is making these decisions on the behalf of a large and unrepresented majority. For example, if you have a company 401(k) managed by a plan, invested in a mutual fund, who hires out their proxy voting to a service, the decision to trade money for social good, and just what constitutes social good, is a long way removed from your preferences. (Me and Vanguard, for example.)

Brazilian Inflation

This marvelous plot comes from an interesting article, The Monetary and Fiscal History of Brazil, 1960-2016 by Joao Ayres, Marcio Garcia, Diogo A. Guillén, and Patrick J. Kehoe. The article is part of the Becker-Friedman Institute Project, complete with a big and now easily available data collection effort, and forthcoming book

If you want a deep historical and economic analysis of fiscal and monetary interactions, this is an amazing resource. And it summarizes historical episodes that North Americans just might want to know more about soon! 

(HT Ricardo Reis who pointed it out in a great discussion last week, that I will post as soon as it's available.)

NBER monetary economics is up to date

I just got the program for the upcoming NBER summer institute monetary economics conference program.  Who says academics aren't up to the minute on policy issues? This will be interesting.
