Lessons Learned I

I spent last week traveling and giving talks. I always learn a lot from this. One insight I got:  Real interest rates are really important in making sense of fiscal policy and inflation.

Harald Uhlig got me thinking again about fiscal policy and inflation, in his skeptical comments on the fiscal theory discussion, available here. At left, two of his graphs, asking pointedly one of the standard questions about the fiscal theory: Ok, then, what about Japan? (And Europe and the US, too, in similar situations. If you don't see the graphs or equations, come to the original.) This question came up several times and I had the benefit of several creative seminar participants views.

The fiscal theory says
 \[ \frac{B_{t-1}}{P_t} = E_t \sum_{j=0}^{\infty} \frac{1}{R_{t,t+j}} s_{t+j} \]
 where \(B\) is nominal debt, \(P\) is the price level, \(R_{t,t+j}\) is the discount rate or real return on government bonds between \( t\) and \(t+j\) and \(s\) are real primary (excluding interest payments) government surpluses. Nominal debt \(B_{t-1}\) is exploding. Surpluses \(s_{t+j}\) are nonexistent -- all our governments are running eternal deficits, and forecasts for long-term fiscal policy are equally dire, with aging populations, slow growth, and exploding social welfare promises. So, asks Harald, where is the huge inflation?

I've sputtered on this one before. Of course the equation holds in any model; it's an identity with \(R\) equal to the real return on government debt; fiscal theory is about the mechanism rather than the equation itself. Sure, markets seem to have faith that rather than a grand global sovereign default via inflation, bondholders seem to have faith that eventually governments will wake up and do the right thing about primary surpluses \(s\). And so forth. But that's not very convincing.

This all leaves out the remaining letter: \(R\). We live in a time of extraordinarily low real interest rates. Lower real rates raise the real value surpluses s. So in the fiscal theory, other things the same, lower real rates are a deflationary force.

Chari and Kehoe on Bailouts

V. V. Chari and Pat Kehoe have a very nice article on bank reform, "A Proposal to Eliminate the Distortions Caused by Bailouts," backed up by a serious academic paper.

Their bottom line proposal is a limit on debt to equity ratios, rising with size. This is, I think, a close cousin to my view that a Pigouvian tax on debt could substitute for much of our regulation.

Banks pose a classic moral hazard problem. In a financial crisis, governments are tempted to bail out bank creditors. Knowing they will do so, bankers take too much risk and people lend to too risky banks. The riskier the bank, the stronger the governments' temptation to bail it out ex-post.

Chari and Pat write with a beautifully disciplined economic perspective: Don't argue about transfers, as rhetorically and politically effective as that might be, but identify the distortion and the resulting inefficiency. Who cares about bailouts? Well, taxpayers obviously. But economists shouldn't worry primarily about this as a transfer. The economic problem is the distortion that higher tax rates impose on the economy. Second, there is a subsidy distortion that bailed out firms and creditors expand at the expense of other, more profitable activities. Third there is a debt and size distortion. Since debt is bailed out but not equity, we get more debt, and the banks who can get bailouts become inefficiently large.

A better living will

"US rejects 'living wills' of 5 banks," from FT. WSJ puts this event in the larger story of Dodd Frank unraveling. Juicy quotes:

WSJ: “living wills,” ... are supposed to show in detail how these banking titans, in the event of failure, could be placed into bankruptcy without wrecking the financial system.

FT:...the shortcomings varied by bank but included flawed computer models; inadequate estimates of liquidity needs; questionable assumptions about the capital required to be wound up; and unacceptable judgments on when to enter banktruptcy.

FT: David Hirschmann of the US Chamber of Commerce, the biggest business lobby, said the living wills process was “broken”. “When you can’t comply no matter how much money you put into legitimately trying to comply, maybe it’s time to ask: did we get the test wrong?” he said.

WSJ: Six years after the law was passed, and eight years since the financial crisis, regulators given broad authority to remake American finance, with thousands of regulatory officials on their payroll, cannot figure out a system to allow financial giants to fail, even in theory. What are we paying these people for?

It seems like a good moment to revisit an idea buried deep in "Toward a run-free financial system."  How could we structure banks to fail transparently?

MetLife

What does "systemically important" mean? How can an institution, per se, be "systemically important?"  The WSJ coverage of Judge Rosemary Collyer’s decision rescinding MetLife’s designation as a "systemically important financial institution:" gives an interesting clue to how our regulators' thinking is evolving on this issue:

The [Financial Stability Oversight] council argued — bromide alert — that “contagion can result when relatively modest direct, individual losses cause financial institutions with widely dispersed exposures to actively manage their balance sheets in a way that destabilizes markets.”

It's not a bromide. It is a revealing capsule of how the FSOC headed by Treasury thinks about this issue.

NBER AP

On Friday I attended the NBER Asset Pricing meeting (program here) in Chicago, organized by Adrien Verdelhan and Debby Lucas. The papers were unusually interesting, even by the high standards of this meeting. Alas the NBER doesn't post slides so I don't have great visuals to show you.

Next Steps for FTPL

Last Friday April 1, Eric Leeper Tom Coleman and I organized a conference at the Becker-Friedman Institute,  "Next Steps for the Fiscal Theory of the Price Level." Follow the link for the whole agenda, slides, and papers.

The theoretical controversies are behind us. But how do we use the fiscal theory, to understand historical episodes, data, policy, and policy regimes? The idea of the conference was to get together and help each other to map out this the agenda. The day started with history, moved on to monetary policy, and then to international issues.

A common theme was various forms of price-related fiscal rules, fiscal analogues to the Taylor rule of monetary policy. In a simple form, suppose primary surpluses rise with the price level, as
\[ b_t = \sum_{j=0}^{\infty} \beta^j \left( s_{0,t+j} + s_1 (P_{t+j} - P^\ast) \right) \]
where \(b_t\) is the real value of debt, \(s_{0,t}\) is a sequence of primary surpluses budgeted to pay off that debt, \(P^\ast\) is a price-level target and \(P_t\) is the price level. \(b_t\) can be real or nominal debt \( b_{t}= B_{t-1}/P_t\), but I write it as real debt to emphasize the point: This equation too can determine price levels \(P_t\). If inflation rises, the government raises taxes or cuts spending to soak up extra money. If inflation declines, the government does the opposite, putting extra money and debt in the economy but in a way that does not trigger higher future surpluses, so it does push up prices.

(Note: this post has embedded figures and mathjax equations. If the last paragraph is garbled or you don't see graphs below, go here.)

That idea surfaced in many of the papers.

Neo-Fisherian caveats

Raise interest rates to raise inflation? Lower interest rates to lower inflation? It's not that simple.

A correspondent from an emerging market wrote enthusiastically. His country has somewhat too high inflation, currency depreciation and slightly negative real rates. A discussion is going on about raising rates to combat inflation. Do I think that lowering rates in this circumstance is instead the way to go about it?

As you can tell, posing the question this way makes me very uncomfortable! So, thinking out loud, why might one pause at jumping this far, this fast?

Fiscal policy.  Fiscal policy deeply underlies monetary policy. In my own "Fisherian" explorations, the fiscal theory of price level is a deep foundation. If the government is printing up money to pay its bills, the central bank can do what it wants with interest rates, inflation is coming anyway.

A very simple neo-Fisherian model

A sharp colleague recently pushed me to write down a really simple model that can clarify the intuition of how raising interest rates might raise, rather than lower, inflation. Here is an answer.

(This follows the last post on the question, which links to a paper. Warning: this post uses mathjax and has graphs. If you don't see them, come back to the original. I have to hit shift-reload twice to see math in Safari. )

I'll use the standard intertemporal-substitution relation, that higher real interest rates induce you to postpone consumption, \[ c_t = E_t c_{t+1} - \sigma(i_t - E_t \pi_{t+1}) \] I'll pair it here with the simplest possible Phillips curve, that inflation is higher when output is higher. \[ \pi_t = \kappa c_t \] I'll also assume that people know about the interest rate rise ahead of time, so \(\pi_{t+1}=E_t\pi_{t+1}\).

Now substitute \(\pi_t\) for \(c_t\), \[ \pi_t = \pi_{t+1} - \sigma \kappa(i_t - \pi_{t+1})\] So the solution is \[ E_t \pi_{t+1} = \frac{1}{1+\sigma\kappa} \pi_t + \frac{\sigma \kappa}{1+\sigma\kappa}i_t \]

Inflation is stable. You can solve this backwards to \[ \pi_{t} = \frac{\sigma \kappa}{1+\sigma\kappa} \sum_{j=0}^\infty \left( \frac{1}{1+\sigma\kappa}\right)^j i_{t-j} \]

Here is a plot of what happens when the Fed raises nominal interest rates, using \(\sigma=1, \kappa=1\):

When interest rates rise, inflation rises steadily.

Now, intuition. (In economics intuition describes equations. If you have intuition but can't quite come up with the equations, you have a hunch not a result.) During the time of high real interest rates -- when the nominal rate has risen, but inflation has not yet caught up -- consumption must grow faster.

People consume less ahead of the time of high real interest rates, so they have more savings, and earn more interest on those savings. Afterwards, they can consume more. Since more consumption pushes up prices, giving more inflation, inflation must also rise during the period of high consumption growth.

One way to look at this is that consumption and inflation was depressed before the rise, because people knew the rise was going to happen. In that sense, higher interest rates do lower consumption, but rational expectations reverses the arrow of time: higher future interest rates lower consumption and inflation today.

(The case of a surprise rise in interest rates is a bit more subtle. It's possible in that case that \(\pi_t\) and \(c_t\) jump down unexpectedly at time \(t\) when \(i_t\) jumps up. Analyzing that case, like all the other complications, takes a paper not a blog post. The point here was to show a simple model that illustrates the possibility of a neo-Fisherian result, not to argue that the result is general. My skeptical colleauge wanted to see how it's even possible.)

I really like that the Phillips curve here is so completely old fashioned. This is Phillips' Phillips curve, with a permanent inflation-output tradeoff. That fact shows squarely where the neo-Fisherian result comes from. The forward-looking intertemporal-substitution IS equation is the central ingredient.

Model 2:

You might object that with this static Phillips curve, there is a permanent inflation-output tradeoff. Maybe we're getting the permanent rise in inflation from the permanent rise in output? No, but let's see it. Here's the same model with an accelerationist Phillips curve, with slowly adaptive expectations. Change the Phillips curve to \[ c_{t} = \kappa(\pi_{t}-\pi_{t-1}^{e}) \] \[ \pi_{t}^{e} = \lambda\pi_{t-1}^{e}+(1-\lambda)\pi_{t} \] or, equivalently, \[ \pi_{t}^{e}=(1-\lambda)\sum_{j=0}^{\infty}\lambda^{j}\pi_{t-j}. \]

Substituting out consumption again, \[ (\pi_{t}-\pi_{t-1}^{e})=(\pi_{t+1}-\pi_{t}^{e})-\sigma\kappa(i_{t}-\pi_{t+1}) \] \[ (1+\sigma\kappa)\pi_{t+1}=\pi_{t}+\pi_{t}^{e}-\pi_{t-1}^{e}+\sigma\kappa i_{t} \] \[ \pi_{t+1}=\frac{1}{1+\sigma\kappa}\left( \pi_{t}+\pi_{t}^{e}-\pi_{t-1} ^{e}\right) +\frac{\sigma\kappa}{1+\sigma\kappa}i_{t}. \] Explicitly, \[ (1+\sigma\kappa)\pi_{t+1}=\pi_{t}+\gamma(1-\lambda)\left[ \sum_{j=0}^{\infty }\lambda^{j}\Delta\pi_{t-j}\right] +\sigma\kappa i_{t} \]

Simulating this model, with \(\lambda=0.9\).

As you can see, we still have a completely positive response. Inflation ends up moving one for one with the rate change. Consumption booms and then slowly reverts to zero. The words are really about the same.

The positive consumption response does not survive with more realistic or better grounded Phillips curves. With the standard forward looking new Keynesian Phillips curve inflation looks about the same, but output goes down throughout the episode: you get stagflation.

The absolutely simplest model is, of course, just \[i_t = r + E_t \pi_{t+1}\]. Then if the Fed raises
the nominal interest rate, inflation must follow. But my challenge was to spell out the market forces
that push inflation up. I'm less able to tell the corresponding story in very simple terms.

Central banks as central planners

Two news items cropped up this week on the general topic of central banks as emergent central planers.: a nice WSJ editorial by James Mackintosh on QE extended to buying corporate debt, and the Fed's proposed rule governing "Macroprudential" countercyclical capital buffers. The ECB also has a new Macroprudential Bulletin with similar ideas that I will not cover because the post is already too long. (Some earlier thoughts on the issue here. As usual, if the quotes aren't showing right, come back to the original of this post here.)

The WSJ editorial:

..as the central banks become more desperate to boost inflation and growth, they are starting to break one of the modern tenets of the profession by funneling that cash directly to what they regard as “good” uses.

The Bank of Japan’s conditions for companies to qualify for central bank funding include

offering an "improving working environment, providing child-care support, or expanding employee-training programs".... increasing capital spending, expanding spending on research and development or boosting what the Bank of Japan calls “human capital.” The latter means pay raises for staff, taking on more people or improving human resources.

The Habit Habit

The Habit Habit. This is an essay expanding slightly on a talk I gave at the University of Melbourne's excellent "Finance Down Under" conference. The slides

(Note: This post uses mathjax for equations and has embedded graphs. Some places that pick up the post don't show these elements. If you can't see them or links come back to the original. Two shift-refreshes seem to cure Safari showing "math processing error".)

Habit past: I start with a quick review of the habit model. I highlight some successes as well as areas where the model needs improvement, that I think would be productive to address.

Habit present: I survey of many current parallel approaches including long run risks, idiosyncratic risks, heterogenous preferences, rare disasters, probability mistakes -- both behavioral and from ambiguity aversion -- and debt or institutional finance. I stress how all these approaches produce quite similar results and mechanisms. They all introduce a business-cycle state variable into the discount factor, so they all give rise to more risk aversion in bad times. The habit model, though less popular than some alternatives, is at least still a contender, and more parsimonious in many ways,

Habits future: I speculate with some simple models that time-varying risk premiums as captured by the habit model can produce a theory of risk-averse recessions, produced by varying risk aversion and precautionary saving, as an alternative to  Keynesian flow constraints or new Keynesian intertemporal substitution. People stopped consuming and investing in 2008 because they were scared to death, not because they wanted less consumption today in return for more consumption tomorrow.

Throughout, the essay focuses on challenges for future research, in many cases that seem like low hanging fruit. PhD students seeking advice on thesis topics: I'll tell you to read this. It also may be useful to colleagues as a teaching note on macro-asset pricing models. (Note, the parallel sections of my coursera class "Asset Pricing" cover some of the same material.)

I'll tempt you with one little exercise taken from late in the essay.

Deflation Puzzle

Larry Summers writes an eloquent FT column "A world stumped by stubbornly low inflation"

Market measures of inflation expectations have been collapsing and on the Fed’s preferred inflation measure are now in the range of 1-1.25 per cent over the next decade.

Inflation expectations are even lower in Europe and Japan. Survey measures have shown sharp declines in recent months. Commodity prices are at multi-decade lows and the dollar has only risen as rapidly as in the past 18 months twice during the past 40 years when it has fluctuated widely

And the Fed is forecasting a return to its 2 per cent inflation target on the basis of models that are not convincing to most outside observers. 

Central bankers [at the G20 meeting] communicated a sense that there was relatively little left that they can do to strengthen growth or even to raise inflation. This message was reinforced by the highly negative market reaction to Japan’s move to negative interest rates.

So why is inflation slowly declining despite our central banks' best efforts? Here is a stab at an answer. I emphasize the central logical points with bullets.

• Interest rates have two effects on inflation: a short-run "liquidity" effect, and a long-run "expected inflation" or "Fisher" effect.  

Premium increase insurance

Marginal Revolution and the Wall Street Journal both pass on a great quote from Warren Buffett:

It’s understandable that the sponsor of the proxy proposal believes Berkshire is especially threatened by climate change because we are a huge insurer, covering all sorts of risks. The sponsor may worry that property losses will skyrocket because of weather changes. And such worries might, in fact, be warranted if we wrote ten- or twenty-year policies at fixed prices. But insurance policies are customarily written for one year and repriced annually to reflect changing exposures. Increased possibilities of loss translate promptly into increased premiums. . . .

Up to now, climate change has not produced more frequent nor more costly hurricanes nor other weather-related events covered by insurance. As a consequence, U.S. super-cat rates have fallen steadily in recent years, which is why we have backed away from that business. If super-cats become costlier and more frequent, the likely—though far from certain—effect on Berkshire’s insurance business would be to make it larger and more profitable.

As a citizen, you may understandably find climate change keeping you up nights. As a homeowner in a low-lying area, you may wish to consider moving. But when you are thinking only as a shareholder of a major insurer, climate change should not be on your list of worries.

The puzzle to me is, why doesn't Berkshire Hathaway write ten- or twenty-year policies at fixed prices? Or, better, why does it not offer a second contract, that ensures you against the event that your regular insurance will be repriced every six months? If people are worried about it, and nobody else is doing it, it would seem they could charge a huge premium.

You may say BH doesn't want the risk, but in a previous letter Buffett explained that BH was selling 99 year put options. And being hugely diversified is precisely what allows a company like this to take some risk.

If it doesn't want to hold the risk it could sell it. Surely there are lots of investors who are  skeptics of climate change -- not warming, but the claim that warming will give rise to more extreme weather and higher insurance payouts; people who cheered at that quote in the WSG -- and would be happy to put their money where their mouths are in the reinsurance market.  

(These thoughts are obviously related to health insurance,  premium increase insurance and long-term guaranteed renewable contracts that solve the preexisting conditions problem.)

Sanders multiplier magic

The critiques of Gerald Friedman's analysis of the Sanders economic plan  continue. The latest and most detailed and careful so far is by David and Christina Romer.

Bottom line:

1. The central idea in Friedman's analysis is that taking $1 from Peter to give to Paul raises overall income by 55 cents.  From this, you get multipliers from raising taxes and spending, from higher minimum wages, more unions, and so forth. 
2. I chuckle a little bit that so many economists who previously liked multipliers now don't like their logical conclusions. 
3. The Romers charge a serious, elementary arithmetic mistake in treating levels vs. growth rates. If they're right Friedman's whole analysis is just wrong on arithmetic.

The analysis

One might have expected that a sympathetic analysis of the Sanders plan would say, look, this is going to cost us a bit of growth, but the fairness and (claimed) better treatment of disadvantaged people are worth it.

Friedman's having none of that. In his analysis, the Sanders plan will also unleash a burst of growth, claims for which would make a fervent supply-sider like Art Laffer blush.

"The Sanders program... will raise the gross domestic product by 37% and per capita income by 33% in 2026; the growth rate of per capita GDP will increase from 1.7% a year to 4.5% a year." And, apparently, raise the growth rate permanently.

Negative rates and FTPL

I've devoted most of my monetary economics research agenda to the Fiscal Theory of the Price Level in the last two decades (collection here). This theory says, fundamentally, that money has value because the government accepts it for taxes, and inflation is fundamentally a fiscal phenomenon over which central banks' conventional tools -- open market operations trading money for government bonds -- have limited power.

Since I grew up in the 1970s, I figured the FTPL would have its day when inflation unexpectedly broke out, again, and central banks were powerless to stop it. I figured that the spread of interest-paying electronic money would so clearly undermine the foundations of MV=PY that its pleasant stories would be quickly abandoned as no longer relevant.

I may have been  exactly wrong on both points: It seems that uncontrolled disinflation or deflation will be the spark for adoption of FTPL ideas; that the equivalence of money and bonds at zero interest rates,  and central banks powerless to create inflation will be the trigger.

These thoughts are prodded by two pieces in the Economist, "Out of Ammo:" and "Unfamiliar Ways Forward" (HT and interesting discussion by Miles Kimball)

If you want inflation (a big if -- I don't, but let's go with the if) how do you get it? Ultra-low rates, huge bond purchases, and lots of talk (forward guidance, higher inflation targets) seem to have no effect. What can governments actually do?

Greece and Taxes

An interview for the Greek Reporter, in English, perhaps cheering the like-minded and sure to infuriate some conventional wisdom.

I agree with the "anti-austerians" on one point: Raising taxes was a bad idea. In my emphasis what counts are marginal tax rates on growth-producing activities, rather than Keynesian pump-priming, however, which is an important distinction.

The article says "A recently released study by the Economics Department at the National Kapodistrian University of Athens revealed that Greece has the third highest taxation rate among 21 European countries." If anyone has a link, especially if it's in English, send it in the comments.

Right Wing NPR

I was listening to NPR this morning over coffee, and nearly spilled it. Host Steve Inskeep was interviewing Mark Surman, Mozilla founder, on the topic of Apple refusing to hand over the keys to the Iphone to the Federal Government (and anyone who might be able to hack the Federal Government. Oh, right, that's never happened!)

INSKEEP: One last thing, coming back to this San Bernardino case, we don't know what's in that iPhone. We don't even know if it's important. But let's spin out the worst case scenario as a prosecutor might. Suppose your side wins, that phone is never opened, and as a result, the government misses a chance to find some other suspect and disrupt some attack. The attack goes forward, and people are killed. Will that have been worth it in order to protect encryption?

Surman, probably flabbergasted that anyone should ask such a question, changed the subject

SURMAN: We need to find ways to really be able to seek communications before they're sent or after they're sent and actually work with law enforcement on doing this well. There are alternative ways to get information, getting access to it before or after it's encrypted. What we want to avoid is creating a precedent where encryption can be broken by an arbitrary third party.

But Inskeep kept at it

INSKEEP: So you're saying, in essence, it may well be harder to catch terrorists, but you can still work at it, and the extra difficulty is worth it.

Remember, this is cloyingly liberal NPR, not some foaming at the mouth right wing program!

Like Surman, I often am too polite to give the right answer to such shocking questions in real time. But with the benefit of hindsight, here's a better answer

COCHRANE: Well, come to think of it, you're right there Steve. And while you're at it, let's keep going. These pesky first and fourth amendments sure get in the way of law enforcement, don't they? I mean all this business about going out and getting warrants, and waiting for a judge is so time consuming. If a terrorist gets away while you're busy getting a warrant, and people are killed, will that really have been worth it to protect some sort of centuries old procedures? If someone stirs up trouble on a Jihadi website, why do we have to allow that? And this annoying business about grand juries, and presenting evidence, and discovery, and Miranda warnings, it's so burdensome. What if some terrorist gets away and kills someone?  The police surely should be allowed to just throw anyone suspicious in jail, to make sure they don't do anything bad. Heck, while you're at it, what's with these prohibitions against torture? Bring back the rack, or start chopping people's fingers off until they talk. If you hold back, and some terrorist kills someone, was your little sense of ethics really worth it?  

There is a reason we have all these protections. There is a reason we need to defend them even in times of turmoil.

Perhaps a President Hillary Clinton will bring a sympathetic ear to the right to digital privacy. She undoubtedly wishes her email had been bullet-proof encrypted, not just from the FBI and NSA, but from the Chinese and Russian hackers likely reading every line.

Update: I realize from some of the comments that the point may not have been clear. This isn't about the Apple decision. It's moot, really, anyway, as even Apple can't open the new Iphones. And one can make cost/benefit arguments either way. My point was about the argument: We will hear quite often in coming years and decades, the argument that even one terrorist caught is worth sacrificing privacy and civil liberty. Be prepared to answer, to point out there are costs as well as benefits, and to list what they are. And, finally, I sound more critical of Inskeep than I should. In fairness, he does not offer an opinion. He asks a question, one commonly asked, and may well have been floating a t-ball in the hope Surman would smash it out of the park as I attempted to do.  Many people will ask that question. It's worth asking, over and over, and rehearsing the answer.

Kashkari on TBTF

Neel Kashkari, the new president of the Minneapolis Fed, is making a splash with a speech about too big to fail, and the need for a deeper and more fundamental reform than Dodd Frank.  I am delighted to hear a Federal Reserve official offering, in public, some of the kinds of thoughts that I and like-minded radicals have been offering for the last few years.

I believe the biggest banks are still too big to fail and continue to pose a significant, ongoing risk to our economy.

Now is the right time for Congress to consider going further than Dodd-Frank with bold, transformational solutions to solve this problem once and for all.

From an economic point of view, now is indeed the right time -- calm before the storm. I'm not so sure now is a great time from a political view! But perhaps anti-Wall Street feelings from both parties can be harnessed to good use.

...When the technology bubble burst in 2000, it was very painful for Silicon Valley and for technology investors, but it did not represent a systemic risk to our economy. Large banks must similarly be able to make mistakes—even very big mistakes—without requiring taxpayer bailouts and without triggering widespread economic damage.

This is a key lesson. As Dodd-Frank spreads to insurance companies, equity mutual funds, and asset managers, we're losing sight of the idea that trying to stop anyone from ever losing money again is not a wise way to prevent a panic. It's the nature of bank liabilities, not their assets, that is the problem.

I learned in the crisis that determining which firms are systemically important—which are TBTF—depends on economic and financial conditions. In a strong, stable economy, the failure of a given bank might not be systemic. The economy and financial firms and markets might be able to withstand a shock from such a failure without much harm to other institutions or to families and businesses. But in a weak economy with skittish markets, policymakers will be very worried about such a bank failure.

In other words, the whole idea of designating an institution that is per se "systemic" is silly.

...there is no simple formula that defines what is systemic. I wish there were. It requires judgment from policymakers to assess conditions at the time.

Here I think Kashkari isn't really learning the lesson. If it's undefinable, even in words, and needs "judgment," then perhaps the idea really is empty.

More deeply, I think we need to apply much the same thinking to regulation that we do to monetary policy. At least in principle, most analysts think some sort of rule is a good idea for monetary policy. Pure discretion leads to volatility, moral hazard, time-inconsistency and so on. We should start talking about good rules for financial crisis management, not just ever greater power and discretion to follow whatever the "judgment" (whim?) of the moment says.

A second lesson for me from the 2008 crisis is that almost by definition, we won’t see the next crisis coming, and it won’t look like what we might be expecting. If we, or markets, recognized an imbalance in the economy, market participants would likely take action to protect themselves. When I first went to Treasury in 2006, Treasury Secretary Henry Paulson directed his staff to work with financial regulators at the Federal Reserve and the Securities and Exchange Commission to look for what might trigger the next crisis... We looked at a number of scenarios, including an individual large bank running into trouble or a hedge fund suffering large losses, among others. We didn’t consider a nationwide housing downturn. It seems so obvious now, but we didn’t see it, and we were looking. We must assume that policymakers will not foresee future crises, either.

This is an unusual and worthy expression of humility. Others advocate loading up the Fed with "macroprudential" regulation and "bubble pricking" tools, on the faith that this time, yes this time, they really will see it coming, and really will do something about it.  Regulators are not wiser, smarter, less behavioral, etc. than traders.

Speaking of the "resolution authority,"

Unfortunately, I am far more skeptical that these tools will be useful to policymakers in the second scenario of a stressed economic environment. Given the massive externalities on Main Street of large bank failures in terms of lost jobs, lost income and lost wealth, no rational policymaker would risk restructuring large firms and forcing losses on creditors and counterparties using the new tools in a risky environment, let alone in a crisis environment like we experienced in 2008. They will be forced to bail out failing institutions—as we were. We were even forced to support large bank mergers, which helped stabilize the immediate crisis, but that we knew would make TBTF worse in the long term.

There are no atheists in foxholes, the saying goes.  Notice "forcing losses on creditors and counterparties." This is exactly right. "Bailouts" are not about saving the institution, they are about saving its creditors. We should always call them "creditor bailouts." And a run is in full swing, and when the hotlines to the Treasury are buzzing "if we lose money on this, then the world will end," anyone in charge will guarantee the debts.

I believe we must begin this work now and give serious consideration to a range of options, including the following:

• Breaking up large banks into smaller, less connected, less important entities.

Here, Kashkari caused a stir in the press. Bernie Sanders voiced approval. Since "breaking up" has no subject -- who is to do this and how? -- and no mechanism, I'll give Kashkari the benefit of the doubt that he had something more sophisticated in mind than brute force.

• Turning large banks into public utilities by forcing them to hold so much capital that they virtually can’t fail (with regulation akin to that of a nuclear power plant).

Aha! My favorite simple solution, more capital!  I'm delighted to hear it. Of course (to whine a bit), banks don't "hold" capital, they "issue" capital -- it's a liability not an asset. And if they have so much capital that they virtually can't fail, what is this business about public utilities? And why in the world do they need regulation akin to that of a nuclear power plant? Given how regulation has spiraled costs, stultified innovation, and stopped expansion of the one scalable carbon-free energy source we have, that's a particularly unfortunate analogy. Or maybe it's an incredibly accurate analogy for just where Dodd-Frank style regulation will lead. The point is the opposite: with "so much capital that they virtually can't fail" they don't need the hopeless project of "systemic" designation, intensive asset risk regulation, and so forth.

• Taxing leverage throughout the financial system to reduce systemic risks wherever they lie.

A Pigouvian tax on short term debt -- after we get rid of all the subsidies for it -- is my other favorite answer.

The financial sector has lobbied hard to preserve its current structure and thrown up endless objections to fundamental change.

Many of the arguments against adoption of a more transformational solution to the problem of TBTF are that the societal benefits of such financial giants somehow justify the exposure to another financial crisis. I find such arguments unpersuasive.

This needs some explanation. Banks produce studies claiming that higher capital requirements or reduced amounts of run-prone short-term funding will cause them to charge more for loans and reduce economic growth. Kashkari is pointing out that these arguments are pretty thin, because the cost of not doing it is immense -- 10 percent or so of GDP lost for nearly a decade and counting is plausible.

Obviously, I don't agree with everything in the speech. Kashkari is a bit too vague about "contagion" "linkages" and so fort for my taste. But the good news is to have this conversation, and not settle in to implementing page 35,427 of Dodd Frank regulations, head in the sand, while we wait for the next crisis.

The rest of the speech outlines his plans to get the Minneapolis Fed working hard on these issues, and to push for them at the larger Fed. This is a project worth watching.

In case I haven't plugged it about 10 times, my agenda for these issues is in Toward a Run-Free Financial System and the many blog posts under the "banking" "financial reform" and "regulation" labels.

Sad CEA Letter

And just as I was getting all weepy about how great and a-political, obejective, non-partisan and all that the CEA is, along comes an open letter from past CEA chairs Alan Krueger, Austan Goolsbee, Chirstina Romer, and Laura D'Andrea Tyson to Senator Sanders, to restore my cynicism.

The heart of the letter is worthy, and commendable: to call out the fact that Senator Sander's campaign is making promises that don't add up, beyond even the usual stretches of campaign rhetoric from both sides.

But read

 When Republicans have proposed large tax cuts for the wealthy..

Hmm. I wonder if Republicans would characterize their proposals that way? How many speeches have you heard saying "we want  large tax cuts for the wealthy!" No, they say they want tax reform to reduce distorting marginal rates and rampant cronyism.

Really, dear colleagues and friends, how would you respond if Republican CEA chairs were to write a similar letter addressing the shortcomings of Trump's plan that started,

When Democrats have proposed incentive-killing growth-killing marginal tax rate increases with lots of exemptions for their donors... 

and goes on to trumpet their sober-minded analysis of the plans, would you be inspired to plaud their "reputation" for objective evidence-based analysis?

So this is just a poke in the eye, a repetition of partisan Democratic campaign rhetoric, stirring up the base by bulverizing the other party.

Why is Washington so polarized? Because even once-respectable academic economists, transported to Washington, cannot stop themselves from this sort of schoolyard taunting, tribalistic attacks, and repetition of their bosses' propaganda.

CEA History

The Council of Economic Advisers has released a history of the CEA on its' 70th anniversary, as  Chapter 7 of the  Economic Report of the President. This piece is very interesting for economists interested in policy.

It's a nice reminder on how much economic policy ideas have changed. In the late 1940s, when the CEA was set up, fiscal policy was everything. Solow's growth model had not been invented, let alone Romer's. Monetary policy was a twinkle in Milton Friedman's eye. Adam Smith had more or less been forgotten. Economic policy was widely thought to consist of just setting the right level of fiscal stimulus, let multipliers work their magic, to achieve "full employment" and economic growth. The piece tracks well the rediscovery of microeconomics and regulation, as well as the shifts in macroeconomic thinking.

It reminds us how much the stage has changed. In the early years there were really no economists working elsewhere in government, and there were no think tanks. Now every agency has a chief economist and a staff, and the CEA isn't (!) the only game in town for producing policy-oriented research. Its role has changed as a consequence.

The CEA has long had many roles,  adviser, calculator of numbers, cheerleader for the Administration's policies, spinner for the Sunday talk shows, and interagency warrior.

One of its most important and least appreciated roles is just to stop silly stuff.

Brooks v. Krugman

I usually try to steer away from Presidential politics, and especially from commentators' habit of analyzing character. But last week's New York Times had two particularly interesting columns that invite breaking the rule: "I Miss Barack Obama" by David Brooks and "How America Was Lost" by Paul Krugman.

As we contemplate a Clinton, Sanders, Trump, or Cruz presidency, we may well continue the pattern that each president's main accomplishment is to burnish nostalgia for his (so far) predecessor. Brooks is feeling that.

And he's right. Say what you will about policy, the Obama Administration has, as Brooks points out,  been staffed by people of basic personal integrity and remarkably scandal-free. (In the conventional sense of "scandal." I'm sure some commenters will contend that the bailouts, Lois Lerner, the EPA, and Dodd-Frank and Obamacare are "scandals," but that's not what we're talking about here.) On economic issues, his main advisers have been thoughtful, credentialed, mainstream Democrats. Obama's speeches on many topics have, as David says, been full of "basic humanity," even if one disagrees with his solutions.
