The cancel culture twitter mob comes to economics

Published

on



Last week we learned  the twitter mob has taken over economics too.

In case you aren’t following, here is the short version of the story. Harald Uhlig, a distingushed macroeconomist at the University of Chicago,  sent out a few tweets questioning the wisdom of quickly “defunding the police.” The twitter mob, led by Paul Krugman and Justin Wolfers, swiftly attacked. A petition circulated, reportedly gaining 500 signatories, demanding his removal as editor of the Journal of Political Economy.  I saw an astonishing number of tweets from economists that I formerly respected and considered to be level headed, fact-and-logic, cause-and-effect analysts of public policies pile on.   The media piled on, with coverage at  New York TimesWall Street Journal Chicago Tribune and a bit of a counterpoint at Fox NewsBreitbart National Review and others. By Friday, the University of Chicago caved in and threw Harald under the bus.

Start by actually reading Harald’s tweets.

Harold criticizes  the “core organization @Blklivesmatter” — the political organization, not the self-evident proposition that Black Lives Matter — for  “#defundthepolice : ‘We call for a national defunding of police.’ ” Harald called for “sensible adults to enter back into the room and have serious, earnest, respectful conversations about it all: e.g. policy reform proposals by  @TheDemocrat and national healing.” And, yes, he made a little fun of protesters, some of whom might just be indulging in the usual habit of youth to disregard the full consequences of revolutionary ambitions.

Now, every sensible person here — including Harald — recognizes that we need fundamental reform of police, and well, “serious, earnest, respectful conversations” about why minority communities are doing so poorly, and better ways than police to address the high crime rates in those communities. As a long-run goal, I happen to think a lot less police is a good policy goal.

But that’s beside the point. Are Harald’s views here, or even his tone, so beyond the pale that he must be instantly shunned and de-frocked?  An immediate “defund the police” is one particular policy avenue advocated by one particular segment of our political debate to address what we all recognize as a pressing problem. Is the wisdom of “defund the police” no longer debateable?

The Chicago Sun-Times thinks it is, in a moving article documenting the first Sunday of protest, in which 85 people were shot, and 24 killed while the cops were busy. Eventually, perhaps, an army of social workers can remove root causes of crime, but if there are no police tomorrow, it seems at least worth discussing whether tomorrow will see another 24 people killed.

Chicago’s Mayor Lori Lightfoot commented on defunding the police:

“I don’t think that’s an appropriate action at this time. I think that the people in our neighborhoods want and have been begging for more police support,” she said. “In light of what’s happened over the last couple days, it would be irresponsible for me to even entertain any idea that we would cut back on our public safety resources at this time.“

The race was on to call Uhlig a racist. Per the Wall Street Journal Maximilian Auffhammer came close.

 a professor at the University of California, Berkeley, tweeted on Tuesday a link to a letter that called for Mr. Uhlig to step down from his post at the journal, with encouragement for others to sign it.

“Prof. Uhlig is welcome to say whatever he wants. But his comments hurt and marginalize people of color and their allies in the economics profession,”

And Lori Lightfoot’s comments do not?  But others soon filled in.  A twitter search for “Uhlig racist” turns up lots of tweets.

The pile-on moved past the usual suspects on twitter. The New York Times reports

Janet L. Yellen, the former Federal Reserve chair, said in an email on Wednesday that “the tweets and blog posts by Harald Uhlig are extremely troubling” and that “it would be appropriate for the University of Chicago, which is the publisher of the Journal of Political Economy, to review Uhlig’s performance and suitability to continue as editor.”

Janet Yellen is not just an accomplished economist, a former Federal Reserve Chair, and a very nice person, she is the sitting president of the American Economic Association.  She is entitled to her views as much as Harald is entitled to his. But here, as in a  letter sent to the membership instructing us how to think and behave on such matters (more later), she speaks on behalf of that association. As ex chair of the Federal Reserve, one can expect Janet to be savvy when talking to reporters about personal vs. institutional opinions.

This is to my knowledge the first and only pronouncement by a President of the AEA, without disclaiming official capacity, on whether tweets issued by members disqualify those members for employment. It is the first such pronouncement that anyone should be investigated for their speech.

The AEA has a “code of conduct,” which encourages

“perfect freedom of economic discussion.”  This goal requires an environment where all can freely participate and where each idea is considered on its own merits.  Economists have a professional obligation to conduct civil and respectful discourse in all forums

The Presidents of the AEA have been silent at, say, Paul Krugman’s history of tweets, columns and even books that violently contravene this code of conduct. Krugman, the King of ad hominem, violates the code in the third word of the title of his book, “Arguing with Zombies,” and over and over again in its pages.  Anyone who disagrees with Krugman is a Zombie? (An insult, by the way, with a dark racial history. Where are you, twitter mob?) He writes that other professional economists are “evil,” “stupid,” and accuses them of being bought.

One might with some justification complain about Uhlig’s tone, though Harald criticized protesters and a political organization, whose extreme language is common, not other economists or people engaged in “respectful discourse.”  Are all protesters beyond Harald’s criticism, even looters who destroyed many Chicago neighborhoods? (Mayor Lightfoot’s phone call with aldermen is a bit critical of some protesters too.)

But neither Krugman, nor most of the twitter mob, nor the AEA, who have been silent on tone so far, have a leg to stand on for a charge that Harald’s tone is way out of line.  Harald’s are the first tweets to receive public reprimand from the sitting president of the American Economic Association.

****

End of the first act, and I take a pause because nothing of what follows bears on the above.

The beginning of the end at Chicago came June 11 via this explosive tweet

June 12 The Chicago Fed fired Uhlig from his consulting arrangemen, and  the JPE suspended him.

Now, the JPE advisory board (Robert Shimer, Lars Hansen Steve Levitt and Philip J. Reny, all good friends and great economists, so my pain here is deep at having to criticize their action) carefully say nothing about the tweets, media coverage, and protest. They cite instead the accusation of discriminatory conduct in a classroom setting. Now, such conduct is a very serious charge.

Ba, now a professor at U C Irvine, was sitting in a class in 2014, six years ago. At the University of Chicago, there was always the issue for classes that meet on Mondays, how do you reschedule the class that would normally take place on Martin Luther King day? It was always a difficult problem, as you can’t find a time when everyone can attend a make-up class.  (Thanksgiving posed a similar scheduling problem.) In that discussion, Harald said something that Ba found offensive — that much is undeniable. What did Harald say about Dr. King? Precise words would help. Clearly in this interaction the tone mattered as much as what was actually said, particularly when Harald reportedly stopped to ask whether his comments had been offensive, a situation ripe for cross-cultural misinterpretation.

Yes, this incident merits investigation, to the extent that one can investigate  comments made in classes six years ago reported via tweet. (Update: Commenters report corroboration of the incident, which will help to have a serious investigation.)

But the JPE, on Friday, was clearly not just responding this accusation.  There is no way on this green earth that a tweet made on Thursday about a comment made in class six years ago leads to being suspended from the JPE on Friday, absent a mob demanding just that head for previous tweets about defunding the police.  And an allegation of misbehavior in class would justify suspending Harald from teaching classes, maybe.

I spent much of my last few years of teaching afraid that I would say something that could be misunderstood and thus be offensive to someone.  Many of my colleagues report the same worries.  It is not good for open and honest communication in the classroom if a tweet about a comment six years ago can instantly destroy you.

Moreover, this is an extremely unusual action. I have known the JPE for 35 years. Not once that I am aware in this time has a JPE editor been publicly suspended for anything. There have been good editors and bad editors. There have been editors who found, improved, and published great papers, and editors who did not perform as well. Most of all there have been periodic crises caused by editors who let dozens if not hundreds of papers pile up, leaving many unattended to for years. Yes, those were eased out, and new editors came in to clean up the mess.  Not one of these editors was ever publicly suspended. And no mention was made of any untoward action by Harald as editor — or even that there is or is contemplated any review of his performance as editor.

Why do I write? Sure, I’m just as afraid of  the Red Guards of our twitter mob as the rest of you, and reluctant to offer contrary opinions. The Krugmans, Wolfers, and other assorted Jacobins are waiting for me to write or tweet one sentence that can be taken out of context and demand my head. I doubt the upper levels of administration at Stanford have any more spine in defense of conservative and libertarian speech than do those of Chicago. But we must speak for free speech before it’s too late. If you donate money to a university, you have a special duty to speak up and let them know where you stand.  Chicago in particular has a courageous statement in favor of free speech.  Demand that they honor their fine words with courageous action.  Others, like my Stanford don’t even have the courage to state it. Demand that they do.

Update: And to the many colleagues who have written to say they feel this way too but don’t dare say anything, you need to speak up too. At a minimum others need to know they are also not alone.

Update: The Economics department at the University of Chicago has issued a statement,

The University is currently reviewing claims that a faculty member engaged in discriminatory conduct on the basis of race in a University classroom.  The Journal of Political Economy has also placed the faculty member on leave from his role as a journal editor.  

Update: Yes, I have updated this post a few times, as some colleagues and friends have kindly emailed to report errors.

Update: To a swath of twitter commenters, who seem willfully to misunderstand everthing, laced with profanities. No, this is not about Harold’s suffering, which does not indeed compare to that of African Americans shot by police. This is about Harold’s ideas, and all of our ideas. If, just perhaps, “defund the police” is a bad policy idea that will reduce inner city minority neighborhoods to the sort of economic depression and wanton gang violence they experienced in the 1970s, then voices that question this orthodoxy must be allowed to speak. The suffering of the 85 people shot in the first weekend of Chicago’s protests is real. The suffering of thousands more who will be shot, and denied lives of peace and opportunity if your ideas turn out wrong, is real. Real progress on these issues will demand changes uncomfortable to all sides of the political and policy debate, not just canceling anyone who dares speak out against a certain left-wing orthodoxy.

Update: June 22 statement from the Economics department.

The University has completed a review of claims that a faculty member engaged in discriminatory conduct on the basis of race in a University classroom.  The review concluded that at this time there is not a basis for a further investigation or disciplinary proceeding.  The University’s policy on harassment, discrimination, and sexual misconduct is posted here.  In light of this outcome, the Journal of Political Economy has returned the faculty member to his role as journal editor.

Update: Will this pacify the twitter mob? Justin Wolfers already chimes in, completely disregarding the facts at hand.

Reclaiming freedom

Published

on


We might be seeing a significant political change, with the left reclaiming freedom and anti-statism from the right.

I'm prompted to say this by the Black Lives Matter slogan, "defund the police" which invites us to see the state as an oppressor. As Grace Blakeley recently tweeted:

People know that the state is fucking them over just as much as their boss or landlord – in fact, it’s helping their boss and landlord fuck them over even more…Rather than saying ‘just give more state power to the goodies (us)’ we need to start saying ‘put power where it belongs – in the hands of working people’.

If we read this alongside the disappearance of right-libertarians (some of whom discovered that they like racism and inequality more than small government) and emergence of big government Toryism, we see a big change from a few years ago. Back then, it was the right who called for a smaller state and much of the left that wanted a bigger one. Now it is, if anything, the opposite*.

In one sense this is a return to normality. Historically, advocates of freedom were opponents of the existing order, such as Tom Paine, John Stuart Mill and – yes – Adam Smith**. And, of course, Marxists have long regarded the state as "a committee for managing the common affairs of the whole bourgeoisie" and looked forward to it withering away.

Which poses the question: why are things now changing (back)?

One reason is that the left has learned that states are indeed often repressive. I'm thinking here not just of police killings but of the social murder that is austerity and tough benefit sanctions, and the forced deportations of black Britons (something still going on).

Secondly, they've learned that, as Grace says, it is not good enough to "give more state power to the goodies". Yes, New Labour did make significant achievements in tax credits, Sure Start and better funding of schools and the NHS. But many of these have been reversed by the Tories in the subsequent decade. The left cannot pin its hopes merely on winning temporary (and partial) control of the state.

Thirdly, changes within capitalism have changed the state. Of course, capital (pdf) has always wielded power over governments. But there was a time when this was relatively benign. In the post-war war mass production Fordist capitalists needed a mass market and hence an affluent working class. Extractive finance capital, though, doesn't. It needs cheap and plentiful money which fiscal austerity helps provide. General Motors needed a large well-paid working class; Goldman Sachs, not so much. This means there is now more tension between the needs of working people and the function of the state than there used to be.

All of which poses the question. What would anti-statist leftism look like?

Many of you might think the slogan "defund the police" goes too far. No matter: we don't know what's right unless we know what's too much. And what is right – as Elinor Ostrom showed – is that the police should be small and locally accountable. Also, there's a strong case for decriminalizing drugs, in part because it removes a pretext for the police to harass black people.

A high universal basic income would also expand freedom, not just by removing the harsh conditionality of Universal Credit, but also by giving us the freedom to reject exploitative labour or to drop out of the labour market to care for others or to train for better work. As Guy Standing says (pdf), "basic Income’s emancipatory value exceeds its monetary value."

Also, left-libertarianism must empower local communities, and embrace the community wealth-building advocated by Martin O'Neil and Joe Guinan and pioneered by Preston council. In weakening the power of central government, localization mitigates the damage done by Tory austerity. And it also gives local people more republican freedom – the freedom to collectively control more of their own lives.

There's something else, which the Black Lives Matter movement is also highlighting. It's that slavery teaches us something about economics. As Peter Doyle shows in a brilliant paper (pdf), markets produce incentives to undermine others' agency. Although slavery is the most extreme example of this we also see it in everyday capitalist labour markets. As Marx said, when we they start work workers leave behind the realm of equality and freedom and become mere factors of production. Left-libertarianism would put in place institutions to resist this and expand the realm of genuine agency. This would comprise worker coops and more local say over public services.

I say all this not to offer detailed blueprints: Marx was right to be sceptical of these. Instead, the point is that the left can and should pick up the cause of freedom now that the right has abandoned it.

* We mustn't be misled by the right's loud assertion of a right to free speech. What they are really proclaiming is the "right" to spout rubbish without any comeback, which is an altogether different matter.

** If you think the Adam Smith Institute is a representative guide to Smith's thinking, the wallet inspectors would like to meet you.

The Surplus Process

Published

on



How should we model surpluses and deficits? In finishing up a recent articleand chapter 5 and 6 of a Fiscal Theory of the Price Level update, a bunch of observations coalesced that are worth passing on in blog post form.

Background: The real value of nominal government debt equals the present value of real primary surpluses, [ frac{B_{t-1}}{P_{t}}=b_{t}=E_{t}sum_{j=0}^{infty}beta^{j}s_{t+j}. ] I ‘m going to use one-period nominal debt and a constant discount rate for simplicity. In the fiscal theory of the price level, the (B) and (s) decisions cause inflation (P). In other theories, the Fed is in charge of (P), and (s) adjusts passively. This distinction does not matter for this discussion. This equation and all the issues in this blog post hold in both fiscal and standard theories.

The question is, what is a reasonable time-series process for (left{s_{t}right} ) consistent with the debt valuation formula? Here are surpluses

The blue line is the NIPA surplus/GDP ratio. The red line is my preferred measure of primary surplus/GDP, and the green line is the NIPA primary surplus/GDP.

The surplus process is persistent and strongly procyclical, strongly correlated with the unemployment rate.  (The picture is debt to GDP and surplus to GDP ratios, but the same present value identity holds with small modifications so for a blog post I won’t add extra notation.)

Something like an AR(1) quickly springs to mind, [ s_{t+1}=rho_{s}s_{t}+varepsilon_{t+1}. ] The main point of this blog post is that this is a terrible, though common, specification.

Write a general MA process, [ s_{t}=a(L)varepsilon_{t}. ] The question is, what’s a reasonable (a(L)?) To that end, look at the innovation version of the present value equation, [ frac{B_{t-1}}{P_{t-1}}Delta E_{t}left( frac{P_{t-1}}{P_{t}}right) =Delta E_{t}sum_{j=0}^{infty}beta^{j}s_{t+j}=sum_{j=0}^{infty}beta ^{j}a_{j}varepsilon_{t}=a(beta)varepsilon_{t}% ] where [ Delta E_{t}=E_{t}-E_{t-1}. ] The weighted some of moving average coefficients (a(beta)) controls the relationship between unexpected inflation and surplus shocks. If (a(beta)) is large, then small surplus shocks correspond to a lot of inflation and vice versa. For the AR(1), (a(beta)=1/(1-rho_{s}beta)approx 2.) Unexpected inflation is twice as volatile as unexpected surplus/deficits.

(a(beta)) captures how much of a deficit is repaid. Consider (a(beta)=0). Since (a_{0}=1), this means that the moving average is s-shaped. For any (a(beta)lt 1), the moving average coefficients must eventually change sign. (a(beta)=0) is the case that all debts are repaid. If (varepsilon_{t}=-1), then eventually surpluses rise to pay off the initial debt, and there is no change to the discounted sum of surpluses. Your debt obeys (a(beta)=0) if you do not default. If you borrow money to buy a house, you have deficits today, but then a string of positive surpluses which pay off the debt with interest.

The MA(1) is a good simple example, [ s_{t}=varepsilon_{t}+thetavarepsilon_{t-1}% ] Here (a(beta)=1+thetabeta). For (a(beta)=0), you need (theta=-beta ^{-1}=-R). The debt -(varepsilon_{t}) is repaid with interest (R).

Let’s look at an estimate. I ran a VAR of surplus and value of debt (v), and I also ran an AR(1).

Here are the response functions to a deficit shock:

The blue solid line with (s=-0.31) comes from a larger VAR, not shown here. The dashed line comes from the two variable VAR, and the line with triangles comes from the AR(1).

The VAR (dashed line) shows a slight s shape. The moving average coefficients gently turn positive. But when you add it up, those overshootings bring us back to (a(beta)=0.26) despite 5 years of negative responses. (I use (beta=1)). The AR(1) version without debt has (a(beta)=2.21), a factor of 10 larger!

Clearly, whether you include debt in a VAR and find a slightly overshooting moving average, or leave debt out of the VAR and find something like an AR(1) makes a major difference. Which is right? Just as obviously, looking at (R^2)   and t-statistics of the one-step ahead regressions is not going to sort this out.

I now get to the point.

Here are 7 related observations that I think collectively push us to the view that (a(beta)) should be a quite small number. The observations use this very simple model with one period debt and a constant discount rate, but the size and magnitude of the puzzles are so strong that even I don’t think time-varying discount rates can overturn them. If so, well, all the more power to the time-varying discount rate! Again, these observations hold equally for active or passive fiscal policy. This is not about FTPL, at least directly.

1) The correlation of deficits and inflation. Reminder, [ frac{B_{t-1}}{P_{t-1}}Delta E_{t}left( frac{P_{t-1}}{P_{t}}right) =a(beta)varepsilon_{t}. ] If we have an AR(1), (a(beta)=1/(1-rho_{s}beta)approx2), and with (sigma(varepsilon)approx5%) in my little VAR, the AR(1) produces 10% inflation in response to a 1 standard deviation deficit shock. We should see 10% unanticipated inflation in recessions! We see if anything slightly less inflation in recessions, and little correlation of inflation with deficits overall. (a(beta)) near zero solves that puzzle.

2) Inflation volatility. The AR(1) likewise predicts that unexpected inflation has about 10% volatility. Unexpected inflation has about 1% volatility. This observation on its own suggests (a(beta)) no larger than 0.2.

3) Bond return volatility and cyclical correlation. The one-year treasury bill is (so far) completely safe in nominal terms. Thus the volatility and cyclical correlation of unexpected inflation is also the volatility and cyclical correlation of real treasury bill returns. The AR(1) predicts that one-year bonds have a standard deviation of returns around 10%, and they lose in recessions, when the AR(1) predicts a big inflation. In fact one-year treasury bills have no more than 1% standard deviation, and do better in recessions.

4) Mean bond returns. In the AR(1) model, bonds have a stock-like volatility and move procyclically. They should have a stock-like mean return and risk premium. In fact, bonds have low volatility and have if anything a negative cyclical beta so yield if anything less than the risk free rate. A small  (a(beta)) generates low bond mean returns as well.

Jiang, Lustig, Van Nieuwerburgh and Xiaolan recently raised this puzzle, using a VAR estimate of the surplus process that generates a high (a(beta)). Looking at the valuation formula [ frac{B_{t-1}}{P_{t}}=E_{t}sum_{j=0}^{infty}beta^{j}s_{t+j}, ] since surpluses are procyclical, volatile, and serially correlated like dividends, shouldn’t surpluses generate a stock-like mean return? But surpluses are crucially different from dividends because debt is not equity. A low surplus (s_{t}) raises  our estimate of subsequent surpluses (s_{t+j}). If we separate out
 [b_{t}=s_{t}+E_{t}sum_{j=1}^{infty}beta^{j}s_{t+j}=s_{t}+beta E_{t}b_{t+1}  ] a decline in the “cashflow” (s_{t}) raises the “price” term (b_{t+1}), so the overall return is risk free. Bad cashflow news lowers stock pries, so both cashflow and price terms move in the same direction. In sum a small (a(beta)lt 1) resolves the Jiang et. al. puzzle. (Disclosure, I wrote them about this months ago, so this view is not a surprise. They disagree.)

5) Surpluses and debt. Looking at that last equation, with a positively correlated surplus process (a(beta)>1), as in the AR(1), a surplus today leads to  larger value of the debt tomorrow. A deficit today leads to lower value of the debt tomorrow. The data scream the opposite pattern. Higher deficits raise the value of debt, higher surpluses pay down that debt. Cumby_Canzoneri_Diba (AER 2001) pointed this out 20 years ago and how it indicates an s-shaped surplus process.  An (a(beta)lt 1) solves their puzzle as well. (They viewed (a(beta)lt 1) as inconsistent with fiscal theory which is not the case.)

6) Financing deficits. With (a(beta)geq1), the government finances all of each deficit by inflating away outstanding debt, and more. With (a(beta)=0), the government finances deficits by selling debt. This statement just adds up what’s missing from the last one. If a deficit leads to lower value of the subsequent debt, how did the government finance the deficit? It has to be by inflating away outstanding debt. To see this, look again at inflation, which I write [ frac{B_{t-1}}{P_{t-1}}Delta E_{t}left( frac{P_{t-1}}{P_{t}}right) =Delta E_{t}s_{t}+Delta E_{t}sum_{j=1}^{infty}beta^{j}s_{t+j}=Delta E_{t}s_{t}+Delta E_{t}beta b_{t+1}=1+left[ a(beta)-1right] varepsilon_{t}. ] If (Delta E_{t}s_{t}=varepsilon_{t}) is negative — a deficit — where does that come from? With (a(beta)>1), the second term is also negative. So the deficit, and more, comes from a big inflation on the left hand side, inflating away outstanding debt. If (a(beta)=0), there is no inflation, and the second term on the right side is positive — the deficit is financed by selling additional debt. The data scream this pattern as well.

7) And, perhaps most of all, when the government sells debt, it raises revenue by so doing. How is that possible? Only if investors think that higher surpluses will eventually pay off that debt. Investors think the surplus process is s-shaped.

All of these phenomena are tied together.  You can’t fix one without the others. If you want to fix the mean government bond return by, say, alluding to a liquidity premium for government bonds, you still have a model that predicts tremendously volatile and procyclical bond returns, volatile and countercyclical inflation, deficits financed by inflating away debt, and deficits that lead to lower values of subsequent debt.

So, I think the VAR gives the right sort of estimate. You can quibble with any estimate, but the overall view of the world required for any estimate that produces a large (a(beta)) seems so thoroughly counterfactual it’s beyond rescue. The US has persuaded investors, so far, that when it issues debt it will mostly repay that debt and not inflate it all away.

Yes, a moving average that overshoots is a little unusual. But that’s what we should expect from debt. Borrow today, pay back tomorrow. Finding the opposite, something like the AR(1), would be truly amazing. And in retrospect, amazing that so many papers (including my own) write this down. Well, clarity only comes in hindsight after a lot of hard work and puzzles.

In more general settings (a(beta)) above zero gives a little bit of inflation from fiscal shocks, but there are also time-varying discount rates and long term debt in the present value formula. I leave all that to the book and papers.

(Jiang et al say they tried it with debt in the VAR and claim it doesn’t make much difference.  But their response functions with debt in the VAR, at left,  show even more overshooting than in my example, so I don’t see how they avoid all the predictions of a small (a(beta)), including a low bond premium.)

A lot of literature on fiscal theory and fiscal sustainability, including my own past papers, used AR(1) or similar surplus processes that don’t allow (a(beta)) near zero. I think a lot of the puzzles that literature encountered comes out of this auxiliary specification. Nothing in fiscal theory prohibits a surplus process with (a(beta)=0) and certainly not (0 lt a(beta)lt 1).

Update

Jiang et al. also claim that it is impossible for any government with a unit root in GDP to issue risk free debt. The hidden assumption is easy to root out. Consider the permanent income model, [ c_t = rk_t + r beta sum beta^j y_{t+j}] Consumption is cointegrated with income and the value of debt. Similarly, we would normally write the surplus process [ s_t = alpha b_t + gamma y_t. ] responding to both debt and GDP. If surplus is only cointegrated with GDP, one imposes ( alpha = 0), which amounts to assuming that governments do not repay debts. The surplus should be cointegrated with GDP and with the value of debt.  Governments with unit roots in GDP can indeed promise to repay their debts.

"The Market Was Made for Man, Not Man for the Market": Time to Ramp Up Direct Cash Payments

Published

on


The need for large redirections of financial flows to avoid large increase in poverty during this coronavirus plague is large. The need for substantial top-ups to spending flows in view of the large jump in savings rates triggered by the arrival of coronavirus is large. The U.S. government continues to be able to borrow at unbelievable terms—terms so unbelievable that, when the accounting is done correctly, a larger national debt is not a drag on the funds the government has available for its other missions but rather a source of current cash flow.

(Why? Because in real population-adjusted terms, people are not charging the government interest on its debt but are instead paying the government to keep their money safe, but that is a discussion for another time.)

Moreover, a plan to have the government top off spending flows by whatever large amount is necessary to immediately return to full employment is moderately conservative, and the only effective way to give American businesses their proper chance to adjust and survive the coronavirus plague. It is, as John Maynard Keynes wrote back in 1936:

moderately conservative… [to] enlarge… the functions of government… [to include] the task of adjusting to one another the propensity to consume and the inducement to invest…. [It is] the condition of the successful functioning of individual [entrepreneurial] initiative. For if effective demand is deficient, not only is the public scandal of wasted resources intolerable, but the individual enterpriser who seeks to bring these resources into action is operating with the odds loaded against him. The game of hazard which he plays is furnished with many zeros, so that the players as a whole will lose if they have the energy and hope to deal all the cards…. [Success then requires] courage and initiative… supplemented by exceptional skill or unusual good fortune. But if effective demand is adequate, average skill and average good fortune will be enough… [thus] preserving [both] efficiency and freedom…

Our financial flows and property orders are a societal accounting system to guide and manage our collective societal division of labor. If dotting the i’s and crossing the t’s in this societal accounting system produces mass unemployment, the right response is to adjust it to produce full employment and then reconcile the accounting entries, not to watch employment fall and then sit around with our thumbs up our butts wondering what to do.

After all, the market was made for man, not man for the market—wasn’t it?:

The unemployment rate is already ​dwarfing​ peak levels from the Great Recession, with ​higher levels​ of unemployment for Black and Latinx workers; GDP is expected to shrink by ​11 percent​ during the second quarter of this year; and ​27 million​ Americans have likely lost their health insurance along with their jobs. Much is still unknown, but it is clear at this point this recession will require significant and sustained stimulus policies that are responsive to the health of the economy. We agree with economists from ​across​ the ​political spectrum​ that concerns about debt and deficit should not get in the way​ of taking appropriately strong measures to stem the downturn now.

Regular, lasting direct stimulus payments will boost consumer spending, driving the economic recovery and shortening the recession. ​Right now, most Americans are just trying to keep their heads above water. The first round of economic impact payments were a lifeline that helped some get by for a few weeks—​early research​ shows that people are spending the stimulus checks quickly and on essentials—but the worst is not over. Consumer spending accounts for about two-thirds of GDP, so reviving the economy will require sustained efforts to strengthen it. Even after businesses start to re-open and jobs begin to come back, there will be ​significant economic fallout​, and demand will continue to lag if people don’t have money to spend. Regular direct stimulus payments tied to economic indicators will help families stay afloat and drive economic activity.

Automatic stabilizers ensure relief for as long as it is needed, promoting a strong recovery and efficient government. ​Many economists believe our response to the Great Recession was ​too small​ and ​too brief​, slowing the recovery and causing preventable harm particularly to low-income people. Cash assistance is an important element of economic aid, injecting resources through direct stimulus payments and ​refundable tax credits​ into low- and middle-income households that need help and are ​likely​ to spend it. That will start a chain reaction to boost local businesses and increase economic activity. Continuing recurring payments until there is reliable evidence of an economic recovery—such as low and declining unemployment—will promote certainty for all sectors of the economy and for state and local governments and federal agencies.
With many unknowns, it is critical to enact policies that will help promote a robust, sustained, racially equitable recovery and will stay in place until Americans are back on their feet.
