Bond Swap

The U.S. Treasury debates new-for-old bond swap, reports FT. The Treasury will issue more of the popular 10 year bonds, and then buy them back at some point before they mature.

The idea is to make treasury markets more uniform and liquid. Once bonds get several years old, they tend to sit in proverbial sock drawers, and they're harder to buy and sell (they are "off the run.") To the extent that this illiquidity lowers their value, the Treasury can buy them back cheaper.

“By buying cheap issues and funding the buybacks with issuance of rich on-the-run securities, the Treasury could enhance liquidity in these issues, while decreasing its borrowing costs,”

There is a lot of writing about "safe" and "liquid" asset shortages, so issuing more of a few popular issues and leaving less outstanding otherwise is beneficial to markets.

Comment.  I like the idea, but I think the Treasury should go further. Coincidentally, I just happen to have recently written an article called "A new structure for U.S. Federal Debt" that explains it all in detail.

When you think about it, the treasury ends up in a strange place. Why would you constantly issue 10 year debt, and then buy it all back when it's (say) 8 year debt? What is the question that this structure solves? (Other than the desire of dealer banks to double their earnings on buying and selling treasury securities!)  

My proposal is simpler: Issue perpetuities. These securities pay $1 coupon forever. Buy these back, not on a regular schedule, but when (!) the day of surpluses comes that the government wants to pay down the debt. Then there is one issue, with market depth in the trillions, and the whole on the run vs. off the run phenomenon disappears. I hope the Treasury will someday at least try selling some perpetuities.

Sally Fama Cochrane on Painting Allegories of the Body By Milene Fernandez, Epoch Times | May 5, 2016

Sally Fama Cochrane paints at Grand Central Atelier in New York on April 8, 2016. (Benjamin Chasteen/Epoch Times)

NEW YORK—When she paints, Sally Fama Cochrane dives into the chasm between invisible and visible worlds—between the inside and the outside of the body, between numbers and emotions, between cold analysis and comforting storytelling. While some old masters painted allegories of time, wisdom, faith, and themes imbued with Greek mythology or religious morals, Cochrane creates her own allegories inspired by a predominant paradigm of this century—science and medicine....

Ok, this has nothing to do with economics, and it's blatant nepotism from a proud dad. But it's fun, you need something to avoid getting to work on a Monday morning,  and the art is really cool.

Global Imbalances

I gave some comments on “Global Imbalances and Currency Wars at the ZLB,” by Ricardo J. Caballero, Emmanuel Farhi, and Pierre-Olivier Gourinchas at the conference, “International Monetary Stability: Past, Present and Future”, Hoover Institution, May 5 2016. My comments are here, the paper is here 

The paper is a very clever and detailed model of "Global Imbalances," "Safe asset shortages" and the zero bound. A country's inability to "produce safe assets" spills, at the zero bound, across to output fluctuations around the world. I disagree with just about everything, and outline an alternative world view.

A quick overview:

Why are interest rates so low? Pierre-Olivier & Co.: countries can't  “produce safe stores of value”
This is entirely a financial friction. Real investment opportunities are unchanged. Economies can’t “produce” enough pieces of paper. Me: Productivity is low, so marginal product of capital is low.

Why is growth so low? Pierre-Olivier: The Zero Lower Bound is a "tipping point." Above the ZLB, things are fine. Below ZLB, the extra saving from above drives output gaps. It's all gaps, demand. Me: Productivity is low, interest rates are low, so output and output growth are low.

Data: I Don't see a big change in dynamics at and before the ZLB. If anything, things are more stable now that central banks are stuck at zero. Too slow, but stable.  Gaps and unemployment are down. It's not "demand" anymore.


Exchange rates. Pierre-Olivier  "indeterminacy when at the ZLB” induces extra volatility. Central banks can try to "coordinate expectations." Me: FTPL gives determinacy, but volatility in exchange rates. There is no big difference at the ZLB.

Safe asset Shortages. Pierre-Olivier: driven by a large mass of infinitely risk averse agents. Risk premia are therefore just as high as in the crisis. Me: Risk premia seem low. And doesn't everyone complain about "reach for yield" and low risk premia?

Observation. These ingredients are plausible about fall 2008. But that's nearly 8 years ago! At some point we have to get past financial crisis theory to not-enough-growth theory.

But, finally, praise. This is a great paper. It clearly articulates a world view, and you can look at the assumptions and mechanisms and decide if you think they make sense. I am in awe that Pierre-Olivier & Co. were able to make a coherent model of these buzzwords.

But great theory is great theory. To a critic, the assumptions are necessary as well as sufficient. I  read it as a brilliant negative paper, almost a parody: Here are the extreme assumptions that it takes to justify all the policy blather about "savings gluts" "global imbalances" "safe asset shortages" and so on. To me, it shows just how empty the idea is, that our policy-makers understand any of this stuff at a scientific, empirically-tested level, and should take strong actions to offset the supposed problems these buzzwords allude to.

I hope this taste gets you to read  my comments and the paper. 

Delong and Logarithms

Brad Delong posted a response to my oped on growth  in the Wall Street Journal. He took issue with my graph, reproduced here,

by making his own graph, here

He characterizes the difference between our graphs with his usual gentlemanly restraint,

"Extraordinarily Unprofessional!!:" "total idiocy" The University of Chicago and the Wall Street Journal Have Very Serious Intellectual Quality Control Problems

and so forth.

If you read Brad, you may wonder what skulduggery I used to make the plot. I will now reveal the dark secret. It's a clever Chicago-school mathematical trick:

Logarithms.

Yes, I plotted log income vs. ease of doing business index.

Now just how much of a sin is this? Well, growth theory is about growth, so it's pretty hard to do without logarithms. If thinking about percentage growth and running regressions with log income on the left hand side is a devious right-wing trick, I'm afraid we're going to have to throw out about 99% of growth theory and empirical economics, including much done by Brad's colleagues at Berkeley.

Furthermore, just look at the graph.  I invite anybody who has sat through a first-year econometrics class where they teach this devious technique to ponder my and Brad's plot, and think whether a level or a log fit is appropriate.

Brad raises one valid concern with all of empirical economics: Endogeneity. The graph is a correlation. How do we know that better ease of doing business causes better business, and not the other way around? In Brad's view, it is equally likely, I guess, that first a contry gets rich, and then it improves its laws and regulations.

I didn't mention this in the Journal, simply for lack of space (try to write anything in 950 words). In a previous blog post, here, I wrote a little bit about it.

One might dismiss the correlation a bit as reverse causation. But look at North vs. South Korea, East vs. West Germany, and the rise of China and India. It seems bad policies really can do a lot of damage. And the US and UK had pretty good institutions when their GDPs were much lower. (Hall and Jones 1999 control for endogeneity in this sort of regression by using instrumental variables.)

(This post isn't hard to find. I linked to from my growth oped post. And if one is curious about "what does John have to say about endogeneity?" -- a rather obvious question, which I ask about twice at every seminar -- it is also possible to email me. )

That post goes on to survey a lot of academic literature on just how important good institutions are to economic growth.

But just think about it. Did North Korea or East Germany first get poor and then get bad institutions? Did the UK and US first get rich, and then develop our rule-of-law and property rights traditions? Is reverse causality at all a plausible explanation for the correlation? Just about every historical episode you can think of goes the other way.

Endogeneity is always an issue in economics, but Brad's case that I am too dumb to have even thought about it, or that this correlation obviously goes the other way,  does not hold up.

But apparently, Brad doesn't know about google, fact checking, or emailing for simple clarifications either. Otherwise he would know that I don't work at Chicago anymore, hardly a secret.

The notion that universities should practice "intellectual quality control" is interesting in this era of declining free speech. Brad, be careful what you wish for.  "Controlling" basic professional ethics may come first.

If anyone is still curious, I posted my data and program to my website, and this post describes it some more. I didn't clean it up well, as I never thought this would be controversial, but at least it documents what I did. Feel free to play with it as you wish.

Update: It's clear from many comments and the twitter storm that many readers, even trained economists, missed this basic point. My graph is an illustration of a conclusion reached by hundreds, if not more, papers in the academic literature. It is not The Evidence, or even particularly novel evidence. Were it so, standard errors, specification search, endogeneity, much better measures of institutions, etc. would be appropriate, as many suggest. My graph is just a quick graphical illustration of the conclusions of much growth economics, including much work by Jones, Acemoglu, Barro, Klenow, and many many others. Institutions matter to economic growth; bad governments have amazing power to ruin economies.  As always in writing, I should have made that clearer; but I thought this literature was familiar to the average economist-blogger.

Update 2: There is, I think, an important mis-specification in a regression of log income on the ease-of-doing business index, which Evan Soltas implicitly points out.  I referred to the index as "simple" and "crude" for this reason, but again it looks like this seemingly obvious point needs expanding.

The World bank's measure is mostly focused on the ease of starting small businesses. When we look at the regulatory sclerosis in the US, it is a much wider phenomenon, encompassing the tax code, social program disincentives, the  recent huge expansion of federal involvement in health and finance, general spread of cronyism, reduction in rule of law, and so forth. These affect large businesses as much or more than small businesses.

Clearly, as we look across countries, the ease of doing business is correlated with these wider legal and regulatory problems. Countries with bad institutions overall also have bad ease of doing business scores. But just as obviously, only fixing the ease of doing business indicators without fixing the larger legal and institutional failures that correlate with those indicators, won't do a whole lot of good, which is what Evan seems to find.

The regulatory program I outlined there and in the longer essay on growth (blog post here, html here,   pdf here) went far beyond ease of doing business indicators, for just this reason.

Update 3: Or, seemingly obvious point #3 that seems to need an answer. A few commenters have questioned  how far "out of sample" one can go. At some point, yes, institutions are perfect and more income will not result from improving them. Where is that? 90? 100? 110? I don't know. But the local derivative is still high, no matter how you fit the "out of sample" points. If you don't think you can draw the line out to 100, going from 82 to 83 still has very large effects.

Central Bank Governance and Oversight Reform

The Hoover Institution Press just published "Central Bank Governance and Oversight Reform," the collected volume of papers, comments, and discussion from last May's conference here by the same name. You can get the  book or e-book here at the Hoover press or here at amazon.com. The individual chapter pdfs are available here.  Press release here.

(My modest contributions are in the preface and a discussion of Paul Tucker's Chapter 1. I agree it would be nice to have a more rule-based approach to lender of last resort and bailout functions, but wouldn't lots of equity so you don't have to mop up so often be even better?)

This is part of an emerging series of monetary policy conferences at Hoover. Tomorrow we will have a conference on international monetary policy. Stay tuned...

The blurb:

How can we balance the central bank’s authority, including independence, with accountability and constraints? Drawn from a 2015 Hoover Institution conference, this book features distinguished scholars and policy makers’ discussing this and other key questions about the Fed. Going beyond the simple decision of whether to raise interest rates, they focus on a deeper set of questions, including, among others, How should the Fed make decisions? How should the Fed govern its internal decision-making processes? What is the trade-off between greater Fed power and less Fed independence? And how should Congress, from which the Fed ultimately receives its authority, oversee the Fed?

The contributors discuss, for instance, whether central banks can both follow rule-based policy in normal times but then take a discretionary, do-what-it-takes approach to stopping financial crises. They evaluate legislation, recently proposed in the U.S. House and Senate, that would require the Fed to describe its monetary policy rule and, if and when the Fed changed or deviated from its rule, explain the reasons. And they discuss to best ways to structure a committee—like the Federal Open Market Committee, which sets interest rates—to make good decisions, as well as offer historical reflections on the governance of the Fed and much more. They conclude with an important reminder: how important it is to have a “healthy separation between government officials who are in charge of spending and those who are in charge of printing money,” the most essential part of good governance.

Growth Interview

I did a short interview with the WSJ's Mary Kissel about my growth oped. If you can't see the embed above, try this direct link or this one. 

WSJ Growth Oped

I did an oped on growth in the Wall Street Journal, titled "Ending America’s Slow-Growth Tailspin." I'll post the full thing here in 30 days.

Blog readers will recognize a distilled version of my longer essay on growth (blog post here, html here,   pdf here), and the graph from Smith v. Jones blog post. I think out loud. The growth essay is much more detailed on diagnosis and especially on policy.

There are three basic ideas (two too many for a good oped).

1) Growth is everything. Increasing growth will do way more for every problem you can name than anything else on the economic agenda. Even if workers in 1910 could have taken all of Rockefeller's wealth, they would have been disastrously poor compared to today.

2) Can policies actually improve growth? The tut-tutters mocked Jeb Bush's 4% aspiration. I outline the "we've run out of ideas" school of thought, most recently in Bob Gordon's thoughtful book; the "everything is right but the zero bound" secular-staglation school, and the view that the growth giant is being held back by a liliputian army of politicized regulators.

As evidence,  I improved on the graph from an earlier post of the World Bank's ease of doing business score vs. GDP per capita,

(if you can't see the graph, click here)

This graph adds a few things relative to the one in WSJ. I added some outliers. Libya and Venzuela seem like countries with good reasons to have temporarily more GDP than their institutions can long support, Rwanda and Georgia the opposite. So the correlation is even better than it looks. Given how crude the world bank measure is, it's surprising it works so well. It's mostly about the difficulties of starting small businesses. I added Greece too to gives some sense of variation within the Euro-US world.

The point: Bad policies can do dramatic harm. Ipso facto, good policies must be able to do a lot of good. The US is not perfect!

A famous economist challenged my view that regulation is causing a lot of problems, noting that all of the big business types he talks to don't complain that much. But I think that's a horrendous selection bias. If you talk to the people still in business, you are talking to the ones that have figured out the political and regulatory game. Go talk to the ones whose businesses are closed, or not even started.

Another point, regulation has been getting worse for decades. Why the slump now? I think that a lot of the government onslaught's effect has been to make the economy less resilient. For example, social security disability is not a problem as long as you have a job. When you lose a job, and go on disability, now the huge disincentive to work, study, move, kicks in.  Recovering from a recession needs new jobs, new businesses, new innovations.

3) A very brief outline of policies to get growth going again. I think the key is to move past the standard rhetoric that defines our current partisan bickering. It's not how much we spend, really, it's how we spend it. Free market economics is not "trickle-down" economics, it's about incentives, simplicity, rule of law, and so forth.
