### Transitory Inflation: A Fisherian Fed?

Should the Fed raise interest rates fast? Or should it leave them alone, figuring inflation will be "transitory?"

Lots of models, including ones I play with, predict that a constant unchanging interest-rate peg leads to stable inflation. If there is a fiscal shock, it leads to a one-period price-level jump, but no further inflation, so long as the interest rate stays where it is. The models in the first few chapters of The Fiscal Theory of the Price Level have this feature, also "Michelson Morley, Fisher and Occam.'' Martin Uribe has also written about this issue, here for example.

The simplest example is $i_t = E_t \pi_{t+1}$ $(E_{t+1}-E_t) \pi_{t+1} = -(E_{t+1}-E_t) \sum_{j=0}^{\infty} \rho^j \tilde{s}_{t+j}$ where $$\tilde{s}$$ denotes real primary surpluses scaled by the value of debt. If the interest rate $$i_t$$ does not move, expected inflation does not move. A fiscal shock (negative $$\tilde{s}$$ ) gives a one-period unexpected inflation, devaluing outstanding debt; essentially a Lucas-Stokey state-contingent default. Sticky prices smooth all this out over a year or two.

You can replace the latter with standard new-Keynesian equilibrium-selection rules if you want. This isn't really about fiscal theory; the key is rational forward-looking expectations in the first equation, which also hold in the standard sticky-price extensions. This "Fisherian" property is a common though widely ignored prediction of most new-Keynesian models.

It certainly seems plausible that we are seeing an inflationary fiscal shock, from trillions of money printed up and sent to consumers, while interest rates stay fixed. These models predict that such inflation will indeed be transitory if the Fed does not raise interest rates, and will rise if it does!

However, like all lower-rates-to-lower-inflation arguments, there are lots of warnings here. In particular, the "transitory" inflation could last a long time once we put in sticky prices. The trick only works if the Fed is completely committed to not raising rates, to waiting as long as it takes for inflation to settle back down on its own.  If people suspect the Fed will raise rates, inflation rises. There are lots of temporary forces that go in the other direction. And there may be more fiscal shocks -- I sort of see one brewing in Congress -- so we may not be done with the unexpected inflation term.

FTPL section 5.3 has a long discussion of all the preconditions for lower interest rates to bring down inflation, which still obtain. But we haven't been talking about this issue much since the low-inflation zero-bound era ended, and the discussion that maybe determined, permanent, pre-announced interest rate rises could eventually bring up inflation. The opposite sign works as well.

In these models, with a few more ingredients than I show above, the Fed can also lower inflation by raising rates. Raising rates gives a temporary inflation decline before going the other way. So, the Fed has to raise rates, push inflation down, then quickly get on the other side. That's the historical pattern, and what it will likely do.  But it's only honest, and fun, to remember the prediction of the opposite possibility and to think about how it might work out.

******

Update. A second try, with more English. The government, Fed and Treasury, basically printed up about $5 trillion of new cash and treasury debt -- these are largely perfect substitutes so the composition doesn't really matter -- with no change at all in plans to repay debt. By simple FTPL, a 25% increase in debt with no increase in expected future surpluses generates a 25% rise in the price level, 25% cumulative inflation. It basically defaults on outstanding debt and transfers that value to the recipients of stimulus. But then it ends. If there is no more issue of nominal debt, without additional surpluses, then there is no more inflation. Additional issues of nominal debt can come from more unbacked fiscal expansion, or it can come from monetary policy. Monetary policy also puts extra government debt (same thing as interest-paying reserves) out there, with (of course) no change in fiscal policy. So there is the FTPL case for "transitory."In the long run, no change in interest rate puts no extra government debt in the system, and higher nominal interest rates must mean eventually higher inflation and hence more unbacked government debt in the system. ## Tuesday, October 26, 2021 ### Central bank expansionism A keynote talk at the FGV EPGE (Brazilian School of Economics and Finance) 60th anniversary conference, program here. Direct link to my talk here (YouTube). (I start at about 4:00 if you're impatient). I plan to turn these thoughts in to an essay at some point. All the conference videos here The theme: Central banks, and especially the US Fed, are spinning out of control. I trace the history of this expansion, and how little steps taken here and there mushroomed. The decision in 2008 to regulate assets rather than pursue equity-financed banking, and buying huge amounts of assets, are small steps that mushroomed. They are the moment that central banks became the proverbial two year old with a hammer. The end, the natural meaning of "whole of government" approaches, must be the end of central bank independence and their complete politicization. ## Monday, October 25, 2021 ### Supply The Revenge of Supply, at Project Syndicate Surging inflation, skyrocketing energy prices, production bottlenecks, shortages, plumbers who won’t return your calls – economic orthodoxy has just run smack into a wall of reality called “supply.” Demand matters too, of course. If people wanted to buy half as much as they do, today’s bottlenecks and shortages would not be happening. But the US Federal Reserve and Treasury have printed trillions of new dollars and sent checks to just about every American. Inflation should not have been terribly hard to foresee; and yet it has caught the Fed completely by surprise. The Fed’s excuse is that the supply shocks are transient symptoms of pent-up demand. But the Fed’s job is – or at least should be – to calibrate how much supply the economy can offer, and then adjust demand to that level and no more. Being surprised by a supply issue is like the Army being surprised by an invasion. The current crunch should change ideas. Renewed respect may come to the real-business-cycle school, which focuses precisely on supply constraints and warns against death by a thousand cuts from supply inefficiencies. Arthur Laffer, whose eponymous curve announced that lower marginal tax rates stimulate growth, ought to be chuckling at the record-breaking revenues that corporate taxes are bringing in this year. Equally, one hopes that we will hear no more from Modern Monetary Theory, whose proponents advocate that the government print money and send it to people. They proclaimed that inflation would not follow, because, as Stephanie Kelton puts it in The Deficit Myth, “there is always slack” in our economy. It is hard to ask for a clearer test. But the US shouldn’t be in a supply crunch. Real (inflation-adjusted) per capita US GDP just barely passed its pre-pandemic level this last quarter, and overall employment is still five million below its previous peak. Why is the supply capacity of the US economy so low? Evidently, there is a lot of sand in the gears. Consequently, the economic-policy task has been upended – or, rather, reoriented to where it should have been all along: focused on reducing supply-side inefficiencies. One underlying problem today is the intersection of labor shortages and Americans who are not even looking for jobs. Although there are more than ten million listed job openings – three million more than the pre-pandemic peak – only six million people are looking for work. All told, the number of people working or looking for work has fallen by three million, from a steady 63% of the working-age population to just 61.6%. We know two things about human behavior: First, if people have more money, they work less. Lottery winners tend to quit their jobs. Second, if the rewards of working are greater, people work more. Our current policies offer a double whammy: more money, but much of it will be taken away if one works. Last summer, it became clear to everyone that people receiving more benefits while unemployed than they would earn from working would not return to the labor market. That problem remains with us and is getting worse. Remember when commentators warned a few years ago that we would need to send basic-income checks to truck drivers whose jobs would soon be eliminated by artificial intelligence? Well, we started sending people checks, and now we are surprised to find that there is a truck driver shortage. Practically every policy on the current agenda compounds this disincentive, adding to the supply constraints. Consider childcare as one tiny example among thousands. Childcare costs have been proclaimed the latest “crisis,” and the “Build Back Better” bill proposes a new open-ended entitlement. Yes, entitlement: “every family who applies for assistance … shall be offered child care assistance” no matter the cost. The bill explodes costs and disincentives. It stipulates that childcare workers must be paid at least as much as elementary school teachers ($63,930), rather than the current average ($25,510). Providers must be licensed. Families pay a fixed and rising fraction of family income. If families earn more money, benefits are reduced. If a couple marries, they pay a higher rate, based on combined income. With payments proclaimed as a fraction of income and the government picking up the rest, either prices will explode or price controls must swiftly follow. Adding to the absurdity, the proposed legislation requires states to implement a “tiered system” of “quality,” but grants everyone the right to a top-tier placement. And this is just one tiny element of a huge bill. Or consider climate policy, which is heading for a rude awakening this winter. This, too, was foreseeable. The current policy focus is on killing off fossil-fuel supply before reliable alternatives are ready at scale. Quiz: If you reduce supply, do prices go up or go down? Europeans facing surging energy prices this fall have just found out. In the United States, policymakers have devised a “whole-of-government” approach to strangle fossil fuels, while repeating the mantra that “climate risk” is threatening fossil-fuel companies with bankruptcy due to low prices. We shall see if the facts shame anyone here. Pleading for OPEC and Russia to open the spigots that we have closed will only go so far. Last week, the International Energy Agency declared that current climate pledges will “create” 13 million new jobs, and that this figure would double in a “Net-Zero Scenario.” But we’re in a labor shortage. If you can’t hire truckers to unload ships, where are these 13 million new workers going to come from, and who is going to do the jobs that they were previously doing? Sooner or later, we have to realize it’s not 1933 anymore, and using more workers to provide the same energy is a cost, not a benefit. It is time to unlock the supply shackles that our governments have created. Government policy prevents people from building more housing. Occupational licenses reduce supply. Labor legislation reduces supply and opportunity, for example, laws requiring that Uber drivers be categorized as employees rather than independent contractors. The infrastructure problem is not money, it is that law and regulation have made infrastructure absurdly expensive, if it can be built at all. Subways now cost more than a billion dollars per mile. Contracting rules, mandates to pay union wages, “buy American” provisions, and suits filed under environmental pretexts gum up the works and reduce supply. We bemoan a labor shortage, yet thousands of would-be immigrants are desperate to come to our shores to work, pay taxes, and get our economy going. A supply crunch with inflation is a great wake-up call. Supply, and efficiency, must now top our economic-policy priorities. ********* Update: I am vaguely aware of many regulations causing port bottlenecks, including union work rules, rules against trucks parking and idling, overtime rules, and so on. But it turns out a crucial bottleneck in the port of LA is... Zoning laws! By zoning law you're not allowed to stack empty containers more than two high, so there is nowhere to leave them but on the truck, which then can't take a full container. The tweet thread is really interesting for suggesting the ports are at a standstill, bottled up FUBARed and SNAFUed, not running full steam but just can't handle the goods. Disclaimer: To my economist friends, yes, using the word "supply" here is not really accurate. "Aggregate supply" is different from the supply of an individual good. Supply of one good increases when its price rises relative to other prices. "Aggregate supply" is the supply of all goods when prices and wages rise together, a much trickier and different concept. What I mean, of course, is something like "the amount produced by the general equilibrium functioning of the economy, supply and demand, in the absence of whatever frictions we call low 'aggregate demand', but as reduced by taxes, regulations, and other market distortions." That being too much of a mouthful, and popular writing using the word "supply" and "supply-side" for this concept, I did not try to bend language towards something more accurate. ## Saturday, October 16, 2021 ### Build back sausage Inspired by Casey Mulligan's blog post, I went to read some of the "Build Back Better" bill. (Is it just me, or doesn't "Build Back Better" sound a lot like "Make America Great Again?") Heavens, not the whole thing -- that's way beyond me. I just read the first half of the child care tax credit, starting on p. 241. I was also inspired by PBS, which, coincidentally, I'm sure, announced last week a Child Care Crisis. Well, what is the federal government going to do about this "crisis?" Following media coverage, I thought this was mostly a line on your income taxes. I was wrong. p. 251 (d) ESTABLISHMENT OF BIRTH THROUGH FIVE CHILD CARE AND EARLY LEARNING ENTITLEMENT PROGRAM.— (1) IN GENERAL.—The Secretary is authorized to administer a child care and early learning entitlement program under which families, ... shall be provided an opportunity to obtain high-quality child care services... (2) ASSISTANCE FOR EVERY ELIGIBLE CHILD.—Beginning on October 1, 2024, every family who applies for assistance under this section...shall be offered child care assistance... A new entitlement. Forever. How much is this going to cost, I wonder? Oh, good, p. 249 ## Wednesday, October 6, 2021 ### Sowell Nobel? There is less than a week to go before the Economics Nobel Prize. Dear Nobel Committee: How can you not give the prize to Tom Sowell this year? Tom's work evidently merits a Nobel purely as a contribution to economics, covering many issues. But we can't ignore what year it is, and what's going on in the world. Indeed, in the Physics and Chemistry prizes this year, as well as Nordhaus' climate-economics Nobel, the Prize committees show they care about research that applies to hot-button problems. Race is a screaming issue of our time. How can you not give the prize to the living economist who has written the most penetrating economic analysis of race? Oh, yes, he's free-market, and thus characterized as conservative. His deeply fact-based research is uncomfortable to The Narrative. For example, groups that white people cannot tell apart have profoundly different outcomes in the US. Nigerian immigrants are among the highest achieving ethnic groups in the US. West Indians do well. Asians of different waves of immigration and different countries -- Chinese, Laotians, Vietnamese -- show profound differences. Tom has thousands of such facts, impeccably documented. But you're the Nobel Committee. You care about Science, not about cheers from the Davos crowd. You care about issues that are important, as you should, but you do not care about embracing one or the other political narrative's answers to those questions. You care about the reputation of your Prize, for courageously recognizing great research, even if its surprising conclusions upset established orders. And, to your credit, you have given the prize to economists of widely different political enthusiasms through the years. You're not, say, the American Economics Association, whose statement from the American Economic Association Executive Committee, still up on its website, and referenced in mandatory DEI training, reads We encourage all economists to seek out existing scholarship on race, stratification economics, and related topics. To get us started, our AEASP and CSMGEP colleagues and students are compiling a reading list on racism and the experience of Black Americans. Members of the AEA Executive Committee have pledged to continue to educate themselves in part by reading works from the list and to seek to integrate work by diverse authors in course syllabi, and we ask all economists to make the same pledge. The officially-endorsed reading list, though updated, to this day brazenly omits Sowell. Or Walter Williams. Or Glenn Loury. Or Roland Fryer. (Committee, if you're looking for others to share the prize, here are some suggestions!) If you must, as you sometimes do, you may shrink from controversy by pairing the prize, Hayek and Myrdal; Fama and Shiller. But give Tom the prize. Yes, Tom's work is empirical, neither full of equations of theory or econometrics. (Though Knowledge and Decisions is an excellent pice of theory.) Tom writes books. Well, maybe it's time to celebrate persuasive fact-based books as well as the more standard approaches, as you also have done in the past. While Tom is hardy, he is 91. None of us last forever. Nor does your opportunity to recognize one of the most important economists of our time. This is the year. ******** Update: If you don't know Tom, and don't want to face an overwhelming volume of primary sources, his Wikipedia page is not bad. Twitter commenters complain that he appears on Fox News. Well, Paul Krugman appears in the New York Times. Within a respectable range, really, we need to start keeping political commentary separate from scientific contribution, like other hobbies. ## Tuesday, October 5, 2021 ### What's in the reconciliation bill? A conversation with Casey Mulligan. A podcast discussion with Casey Mulligan. What's in the reconciliation bill? How will it work? Link to the podcast page, with lots of other formats. Yesterday Casey tweeted that he had read the entire 2,400 page bill. Casey does this sort of thing, as explained in his book "Your'e hired." I have been trying to figure out what's in it for a while. The media coverage is basically absent. (See this great Marginal Revolution post and Bloomberg column (gated, sadly) by Tyler Cowen.) I tried downloading the actual bill too, but promptly fell asleep. (Casey has some good hints on how to read it.) But here we are, about to embark on a huge set of new federal programs, really larger than anything since the Johnson Administration, and there is essentially no description of what they are, no debate on how they will work, and especially (my hobby horse) what incentives and disincentives they provide. Many of the previous welfare-state programs were disastrous for the supposed beneficiaries. How are we going to avoid that again? At most we talk about top line numbers. I'm a debt hawk, but if we could heal the planet, end all inequity, bring full social racial and gender justice, wipe out poverty, give every American a life of dignity, prosperity, and opportunity for a mere$3.5 trillion, I'm in. Double it. The real question is whether any of this will happen.

Well, Casey read the bill and knows what's in it! Tune in to find out..

PS, I hope to get the podcast going more regularly this fall,

Update:

A summary and review from David Henderson.

Casey writes a detailed blog post on BBB disincentives.

### "Non-profit" housing at NYT

Every now and then the old New York Times resurfaces, with detailed reporting, actual facts, whether or not they support The Narrative. Such is the case with an article I recommend, Housing Boss Earns $1 Million to Run Shelters Despite a Troubled Past, by Amy Julia Harris Since 2017, ... the city has awarded more than$352 million to a nonprofit run by Mr. [Jack A.] Brown to operate shelters. The money is meant to help homeless people regain their footing in life, but it has benefited Mr. Brown, too.

The nonprofit has channeled contracts worth at least $32 million into for-profit companies tied to Mr. Brown, allowing him to earn more than$1 million a year, The New York Times found. Millions more have gone to real estate companies in which he has an ownership interest.

...In addition to serving as the chief executive of the nonprofit he founded, CORE Services Group, Mr. Brown started a security guard company that polices his shelters, a maintenance company that makes repairs in them and a catering company that feeds the residents, records showed. Mr. Brown heads each of them, collecting total compensation that tops $1 million. He is the highest-paid shelter operator in New York, according to a review of available records. Mr. Brown, 53, has profited in other ways: Along with partners, he owns two companies that have rented buildings to CORE, and his mother, sister, aunt and niece have all worked at the nonprofit, in addition to his brother, who has collected a six-figure salary. At the same time, residents at one of the largest shelters in Mr. Brown’s operation, Beach House in Queens, said they lived with vermin infestations, creeping mold and violent fights in the hallways. The last part of the article goes on about Mr. Brown. I have to say I admire the man's cleverness. He starts and closes companies with alacrity, always one step ahead. I am reminded of the famous railroad robber barons, like the one whose name adorns my university, who ran railroads that received massive federal subsidies, but also ran construction companies hired by the railroads to do the work. That's where they made their money, and economic historians still haven't untangled the web. But Mr. Brown is not a lone individual, he's just the human face of the story. As the article makes clear, this is the systematic pattern in the business: An investigation by The Times, based on hundreds of pages of legal filings, business records and tax documents, as well as interviews with homeless people, city officials and shelter employees, found that under the cloak of charity, executives at nonprofits have collected large salaries, spent their budgets on companies that they or their families controlled and installed relatives in high-paying jobs. One landlord started a nonprofit that handed out millions of dollars to real estate and maintenance companies that he and his family owned. A Bronx shelter operator was charged earlier this year with laundering kickbacks through a consulting company run by his family. A former board member of another homelessness organization is under criminal investigation after the city said the group paid millions of dollars to a web of for-profit entities he secretly oversaw. Now, perhaps the gloss of blaming problems in well-meaning programs on malfeasant individuals got this past the the Times' editors. But ponder just how much this story undermines the Standard Progressive Narrative. Most of all, it is these days fashionable to view "for profit" companies as evil, and "non-profits" as morally and ethically superior. For example, When Mayor Bill de Blasio came into office, he criticized a small group of landlords for charging the city exorbitant rates to house people in squalid rooms while doing little to curb homelessness. In 2017, the mayor pledged to open dozens of new shelters that would be managed by nonprofit groups. Their mission, he said, would be altruistic rather than driven by financial gain. You only have to read a little between the lines that the whole system of city grants to "non-profits" is completely and inherently corrupt. Non-profit means a) tax exemption b) no pesky shareholders to ask questions and unseat bad management. Alas, the desire for gain remains in the human spirit. The war on for-profit universities has a similar tone. ...This year, the city has directed$2.6 billion to nonprofits to operate homeless shelters, and officials already know they have a problem with some of them.

...About 77,000 homeless people live in New York City,

$2.6b/77k =$34,000. (The right number should be the number in this housing, which the article does not give.) Well, that's better than San Francisco, where we add a zero.

### Portfolio podcast

I did a Rational Reminder podcast and video, focusing on portfolio theory, but also a tour through asset pricing. My hosts Benjamin Felix and Cameron Passmore were unusually well prepared and asked great questions! Video below, or go here for video, podcast, and transcript for people (like me) who read more than listen.
