Segregated Cash Accounts

An important little item from the just released minutes of the October Federal Open Market Committee meeting will be interesting to people who follow monetary policy and financial reform issues.
Finally, the manager reported on potential arrangements that would allow depository institutions to pledge funds held in a segregated account at the Federal Reserve as collateral in borrowing transactions with private creditors and would provide an additional supplementary tool during policy normalization; the manager noted possible next steps that the staff could potentially undertake to investigate the issues related to such arrangements.
A slide presentation by the New York Fed's Jamie McAndrews explains it.

The simple version, as I understand it, seems like great news. Basically, a company can deposit money at a bank, and the bank turns around and invests that money in interest-paying reserves at the Fed. Unlike regular deposits, which you lose if the bank goes under, (these deposits are much bigger than the insured limit) the depositor has a collateral claim to the reserves at the Fed.

This is then exactly 100% reserve, bankruptcy-remote, "narrow banking" deposits.  I argued for these in "toward a run-free financial system" as a substitute for all the run-prone shadow-banking that fell apart in the financial crisis. (No, this isn't going to siphon money away from bank lending, as the Fed buys Treasuries to issue reserves. The volume of bank lending stays the same.)

Dusty corners of the market

Thursday and Friday I attended the NBER Asset Pricing conference. As usual it was full of interesting papers and sharp discussion. Program here.

A bloggable insight: Itamar Drechsler, and Qingyi F. Drechsler "The Shorting Premium and Asset Pricing Anomalies." They carefully found the cost to short-sell stocks.

Here's their Table 5. F0 are all the easy to short stocks. F3 are the hardest to short stocks. They construct long-short anomaly portfolios in each group. "F 0 Mom" for example is the average monthly return of past winners minus that of past losers, among the easy to short stocks. Now compare the F0 row to the F3 row. The anomaly returns only work in the hard-to-short portfolios.

The second panel shows  Fama-French alphas, which are better measured. The sample is alas small. But the result is cool.

The implication is that a lot of anomalies exist only in hard to trade stocks. There is a lot more in the paper, of course.


Table 5: Anomaly Returns Conditional on Shorting Fees

We divide the short-fee deciles from Table 2 into four buckets. Deciles 1-8, the low-fee stocks, are placed into the F0 bucket. Deciles 9 and 10, the intermediate- and high-fee stocks, are divided into three equal-sized buckets, F1 to F3, based on shorting fee, with F3 containing the highest fee stocks. We then sort the stocks within each bucket into portfolios based on the anomaly characteristic and let the bucket's long-short anomaly return be given by the di erence between the returns of the extreme portfolios. Due to the larger number of stocks in the F0 bucket, we sort it into deciles based on the anomaly characteristic, while F1 to F3 are sorted into terciles. Panel A reports the monthly anomaly long-short returns for each anomaly and bucket. Panel B reports the corresponding FF4 alphas. Panel C reports the FF4 + CME alphas. The sample period is January 2004 to December 2013.

(From Table 4 caption) The anomalies are: value-growth (B=M), momentum (mom), idiosyncratic volatility (ivol), composite equity issuance (cei), nancial distress (distress), max return (maxret), net share issuance (nsi), and gross pro tability (gprof). The sample is January 2004 to December 2013.

Inequality at WSJ

"What the Inequality Warriors Really Want" a Wall Street Journal oped on inequality. It's a much edited version of my evolving "Why and How we Care About Inequality" essay. Any writers will appreciate the pain that cutting so much caused.

As usual I can't post the whole thing for 30 days, but you might find the WSJ short version interesting, especially if you couldn't slog through the whole thing. Their comments might be fun too.

Guilds

The Syndics of the Drapers' Guild by Rembrandt, 1662.

I enjoyed Sheilagh Ogilvie's The Economics of Guilds in the latest Journal of Economic Perspectives. Bottom line:
..the behavior of guilds can best be understood as being aimed at securing rents for guild members; guilds then transferred a share of these rents to political elites in return for granting and enforcing the legal privileges that enabled guilds to engage in rent extraction. 
The paper nicely works through all the standard pro-guild and pro-regulation arguments. If you just replace "Guild" with "regulatory agency" it sounds pretty fresh.

Did guilds provide contract enforcement, security in weak states, property right protections not otherwise available? No.

Who is afraid of a little deflation?

Who is afraid of a little deflation? Wall Street Journal Op-Ed.

Fears of "tipping" into deflation are overblown. I poke a little fun at sticky wages, Fed headroom, deflation-induced defaults and the long-predicted Keynesian deflationary spiral that never seems to happen, and the doom and gloom language from the ECB, IMF and other worriers who just happen to (of course) want to spend trillions to fix this latest "biggest economic problem."

One point that went by a little too quickly in the interest of space: Deflation can be a symptom of bad things. The issue is whether deflation is by itself a bad thing, and causes further damage.

Also, I should have been clearer on a big bottom line: we don't need huge "infrastructure" projects just to save us from deflation.  

They ask me not to post the whole thing for 30 days, so those of you without WSJ access will just have to google or wait breathlessly.

Update: Ed Leamer wrote a great similar piece for Economists' Voice a while back "Deflation Dread Disorder; 'The CPI is Falling!'"  In addition to a better title, he's got a cool Godzilla reference and picture.

Reason for big Government: The Firm

I enjoyed John Goodman's essay at Forbes.com, "Reason for big Government: The Firm"
California has a new law that requires all eggs sold in the state to come from chickens that are housed in roomier cages. Specifically, the hens “must be able to lie down, stand up and fully spread their wings.” 
So how many Californians have been arrested for eating the wrong kind of egg? Zero. Not even one? Not one. Actually, the law doesn’t take effect until January, but even then egg eaters will have nothing to fear. The reason: the law doesn’t apply to people who eat eggs. It only applies to people who sell eggs.

The Neo-Fisherian Question

On the "Neo-Fisherian" idea that maybe raising interest rates raises inflation, Nick Rowe asks an important question. What about the impression, most recently in a host of countries that seemed to raise rates "too early" and then backed off, that raising interest rates lowers inflation? (And thanks to commenter Edward for the pointer.)

Partly in answer, and partly just in mulling it over, I think I can boil down the issue to this question:

If the central bank pegs the nominal rate at a fixed value, is the economy eventually stable, converging to the interest rate peg minus the real rate? Or is it unstable, careening off to hyperinflation or deflationary spiral?

Here are some possibilities to consider. At left is what we might call the pure neo-Fisherian view. Raise interest rates, and inflation will come.

I guess there is a super-pure view which would say that expected inflation rises right away. But that's not necessary. The plot in Monetary Policy with Interest on Reserves worked out a simple sticky price model. In that model, dynamics were pretty much as I have graphed to the left: real rates rise for the period of price stickiness, then inflation sets in.

Now,  here is a possibility that I think might satisfy  Neo-Fisherism, Nick, and a lot of people's intuition:

In response to the interest rate rise, indeed in the short run inflation declines. But if the central bank were to persist, and just leave the target alone, the economy really is stable, and eventually inflation would give up and return to the Fisher relation fold. (I was trying to get the model of "Interest on Reserves" to produce this result, but couldn't do it. Maybe fancier price stickiness, habits, adjustment costs...?)

This view would account for the Swedish and other experience.

We don't see the Fisher prediction because central banks never leave interest rates resolutely pegged. Instead, they pursue short-run pushing inflation around.

Across the Great Divide

Across the Great Divide: New Perspectives on the Financial Crisis is published. This is the book form of the joint Brookings-Hoover conference on the financial crisis, organized by Martin Baily and John Taylor.  The link allows you to download the whole thing as pdf for free, or buy the book.

There will be a webcast book event on Wed Nov 5, from the Hoover Institution's Washington D. C. offices, also available after the fact at that link.

My "Toward a Run-Free Financial System" is in it, in published form, also available on my webpage.

Larry Summers' Low Equilibrium Real Rates,  Financial Crisis, and Secular Stagnation is an interesting read in his evolving case for "secular stagnation," which I'm sure will get a lot of attention.

But lots of the other papers are really interesting as well.
Previous posts on this interesting conference here and on the Summers speech here.

Monetary Policy with Interest On Reserves

Or, Heretics Part II

I just finished a big update of a working paper, "Monetary Policy with Interest on Reserves." It also sheds light on the question, what is the sign of monetary policy? (Previous posts herehere and here).

Again, the big issue is whether the "Fisherian" (Shall we call it "Neo-Fisherian?") possibility works. The Fisher equation says nominal interest rate = real interest rate plus expected inflation. So by raising nominal interest rates, maybe expected inflation rises?

The usual answer is "no, because prices are sticky." So, I worked out a very simple new-Keynesian sticky price model in which prices are set 4 periods in advance.

The top left panel of the graph shows the heretical result. I suppose the Fed raises interest rates by 1 percentage point for two periods, then brings interest rates back down (blue line). Prices are stuck for 4 periods (red line) so don't move. After 4 periods prices fully absorb the repressed inflation -- the Fisher equation works great, only waiting for prices to be able to move.

In the meantime the higher real interest rates (green) induce a little boom in consumption. So, raising rates not only raises inflation, it gives you a little output boost along the way! Raising rates forever does the same thing, but sets off a permanent inflation once price stickiness ends.  

Why do conventional models give a different result?

Heretics

Low inflation is back in the news.  The Wall Street Journal covers the latest decline in European inflation. Peter Schiff has a nice article explaining that inflation is not such a great thing, unless of course you're a government that wants to pay back debt with cheap money. I dipped into this heresy in an earlier post, explaining that maybe zero rates and slight deflation just represent the arrival of Milton Friedman's optimal quantity of money.

But this news also brings to mind some thoughts on the second heresy -- maybe we have the sign wrong, and we're getting low inflation or deflation because interest rates are pegged at zero, and maybe the way to raise inflation (if you want to) is for the Fed to raise interest rates, and leave them there. (Earlier posts on this question  here and here)

Back in 2010, Narayana Kocherlakota explained the basic idea
Long-run monetary neutrality is an uncontroversial, simple, but nonetheless profound proposition. In particular, it implies that if the FOMC maintains the fed funds rate at its current level of 0-25 basis points for too long, both anticipated and actual inflation have to become negative. Why? It’s simple arithmetic. Let’s say that the real rate of return on safe investments is 1 percent and we need to add an amount of anticipated inflation that will result in a fed funds rate of 0.25 percent. The only way to get that is to add a negative number—in this case, –0.75 percent.
To sum up, over the long run, a low fed funds rate must lead to consistent, but low, levels of deflation.”
It's really simple. One of the most fundamental relations in economics is the Fisher equation, nominal interest rate = real interest rate plus expected inflation. Real interest rates can be affected by monetary policy in the short run. But not forever. So if the Fed raises the nominal interest rate and leaves it there, expected inflation should eventually rise to meed that nominal rate.

Chicken and Egg Inequality

The FT's Martin Wolf weighs in on "Why inequality is such a drag on economies"

This is the question that was bugging me last week. Why is inequality a problem in and of itself, rather representing a symptom of problems that should be fixed for their own sake?

Since last week's review of these ideas was rather scathing, I hoped Wolf would offer some new, and better tested ideas.

Alas, and interestingly, no.

Envy and excess

In the inequality post, I puzzled over the following conundrum:
Why does it matter at all to a vegetable picker in Fresno, or an unemployed teenager on the south side of Chicago, whether 10 or 100 hedge fund managers in Greenwich have private jets? How do they even know how many hedge fund managers fly private? They have hard lives, and a lot of problems. But just what problem does top 1% inequality really represent to them? 
I emphasized the quantity issue here. His grandfather in the 1930s watched movies and saw glamorous lifestyles way beyond what he could achieve. Increasing inequality is about larger numbers who live a lavish lifestyle. And the claim is that increasing inequality is changing behavior.

There is a view motivating the left that inequality is just unjust so we - the federal government is always "we" -- have to stop it. If they'd say that, fine, we could have  productive discussion.

But they say, and I was going after in the post, all sorts of other things. That inequality will cause poor people to spend too much, that it will cause them to rise in political rebellion, for example. For that to happen, for the presence of the rich to affect their behavior in any way, they have to know about how the exploding 1/10 of 1% live, and how many of them there are. Which just doesn't make any sense.

Paul Krugman had a few revealing columns over the weekend. (No, not the endlessly repeated Say's Law calumny. I trust you all understand how empty that is.)

Returns to unwanted education

In my inequality post, I wrote, somewhat speculatively,
The returns to education chosen and worked hard for are not necessarily replicated in education subsidized or forced.
Marginal Revolution points to a nice new paper by Pierre Mouganie making this point. From the abstract:
In 1997, the French government put into effect a law that permanently exempted young French male citizens born after Jan 1, 1979 from mandatory military service while still requiring those born before that cutoff date to serve. ... conscription eligibility induces a significant increase in years of education, which is consistent with conscription avoidance behavior. However, this increased education does not result in either an increase in graduation rates, or in employment and wages. Additional evidence shows conscription has no direct effect on earnings, suggesting that the returns to education induced by this policy was zero.

Why and how we care about inequality

Note: These are remarks I gave in a concluding panel at the Conference on Inequality in Memory of Gary Becker, Hoover Institution, September 26 2014. The conference program here, and John Taylor's summary here, where you can see the great papers I allude to. I'll probably rework this to a more general essay, so I reserve the right to recycle some points later.

Why and How We Care About Inequality

Wrapping up a wonderful conference about facts, our panel is supposed to talk about “solutions” to the “problem” of inequality.

We have before us one “solution,” the demand from the left for confiscatory income and wealth taxation, and a substantial enlargement of the control of economic activity by the State.

Note I don’t say “redistribution” though some academics dream about it. We all know there isn’t enough money, especially to address real global poverty, and the sad fact is that government checks don’t cure poverty. President Obama was refreshingly clear, calling for confiscatory taxation even if it raised no income. “Off with their heads” solves inequality, in a French-Revolution sort of way, and not by using the hair to make wigs for the poor. The agenda includes a big expansion of spending on government programs, minimum wages, “living wages,” government control of wages, especially by minutely divided groups, CEO pay regulation, unions, “regulation” of banks, central direction of all finance, and so on. The logic is inescapable. To “solve inequality,” don’t just take money from the rich. Stop people, and especially the “wrong” people, from getting rich in the first place.

In this context, I think it is a mistake to accept the premise that inequality, per se, is a “problem” needing to be “solved,” and to craft “alternative solutions.”

Just why is inequality, per se, a problem?

Suppose a sack of money blows in the room. Some of you get $100, some get $10. Are we collectively better off? If you think “inequality” is a problem, no. We should decline the gift. We should, in fact, take something from people who got nothing, to keep the lucky ones from their $100. This is a hard case to make.

One sensible response is to acknowledge that inequality, by itself, is not a problem. Inequality is a symptom of other problems. I think this is exactly the constructive tone that this conference has taken.

But there are lots of different kinds of inequality, and an enormous variety of different mechanisms at work. Lumping them all together, and attacking the symptom, “inequality,” without attacking the problems is a mistake. It’s like saying “fever is a problem. So medicine shall consist of reducing fevers.”

A few things the Fed has done right -- the oped

Now that 30 days have passed, I can post the whole oped from the Wall Street Journal. See previous post for additional commentary

A Few Things the Fed Has Done Right

The Fed's plan to maintain a large balance sheet and pay interest on bank reserves is good for financial stability.

As Federal Reserve officials lay the groundwork for raising interest rates, they are doing a few things right. They need a little cheering, and a bit more courage of their convictions.

The Fed now has a huge balance sheet. It owns about $4 trillion of Treasury bonds and mortgage-backed securities. It owes about $2.7 trillion of reserves (accounts banks have at the Fed), and $1.3 trillion of currency. When it is time to raise interest rates, the Fed will simply raise the interest it pays on reserves. It does not need to soak up those trillions of dollars of reserves by selling trillions of dollars of assets.

The Fed's plan to maintain a large balance sheet and pay interest on bank reserves, begun under former Chairman Ben Bernanke and continued under current Chair Janet Yellen, is highly desirable for a number of reasons—the most important of which is financial stability. Short version: Banks holding lots of reserves don't go under.

This policy is new and controversial. However, many arguments against it are based on fallacies.

Yellen on the poverty of the poor.

I ran across this interesting speech by Fed Chair Janet Yellen, "The importance of asset building for low and middle income households."
The median net worth reported by the bottom fifth of households by income was only $6,400 in 2013. Among this group, representing about 25 million American households, many families had no wealth or had negative net worth. The next fifth of households by income had median net worth of just $27,900.
But even these numbers are in a sense overstated, since much of the "net worth" is in home equity, thus not easily available
Home equity accounts for the lion's share of wealth... for lower and middle income families, financial assets, including 401 (k) plans and pensions, are still a very small share of their assets. 
This matters because,
for many lower-income families without assets, the definition of a financial crisis is a month or two without a paycheck, or the advent of a sudden illness or some other unexpected expense. .... According to the Board's recent Survey of Household Economics and Decisionmaking, an unexpected expense of just $400 would prompt the majority [!] of households to borrow money, sell something, or simply not pay at all. 
["Majority" meaning 51% of all households seems like a lot, if the bottom 2/5 has $27,500. But I didn't look it up.]

This all brings to mind several thoughts.

Capital Language

Sometimes the press deserves a little applause. Peter Coy at Business Week and Pat Regnier at Time both wrote articles very nicely explaining bank capital and many fallacies around it.

Both articles also have nice graphics, but I give Coy and BusinessWeek the A+, because it also explains that banks can build capital without cutting lending.


A few select quotes. From Coy at Business Week, two fallacies skewered:
So what exactly is capital? Sometimes it’s described as a rainy-day fund, which is wrong. More often it’s characterized as something banks “hold,” which can make it sound like a pile of money that has to be set aside so it can’t be lent out for a profit. That’s not right either.
The American Bankers Association says that higher capital requirements for big banks “reduce economic and job growth.” But banks can meet capital requirements without cutting back lending. They just have to sell more shares (cutting down on buybacks also works) or reduce cash-draining dividends (refraining from raising them also helps).  
Regnier at Time too, and passes on the useful housing analogy.
...As Admati frequently points out, banks have benefited from the misconception that higher capital requirements means banks would have to keep 20% or 30% of their money locked up in a vault, instead of lending it out to businesses or homeowners.
In fact, making banks “hold more capital” actually means they have to borrow less. In their book, Admati and Hellwig show that this is almost exactly like a homeowner making sure to build up equity in her house. 
To raise more capital, banks wouldn’t hold back lending. Rather, they’d tap their shareholders, either by issuing new stock or just by cutting the dividends they pay out of earnings, letting profits build up on the balance sheet. 
It's refreshing when professional writers explain things a lot more clearly and succinctly than us academics seem to do, and get the economics spot on.  Yes, words, stories, and ideas do matter, and the change in attitude about bank capital is a great example.

HT to Anat Admati who sent me the links.

The case for open borders

Alex Tabarrok has a splendid post "the case for open borders" on Marginal Revolution.

Along the way he points to "Economics and Immigration: Trillion Dollar Bills on the Sidewalk?" by Michael Clemens and forthcoming Journal of Economic Perspectives, "The Domestic Economic Impacts of Immigration" by David Roodman and "The case for Open Borders" by Dylan Matthews, a Bryan Caplan interview and story on vox. All are worth reading.

1) Women

Anecdotes and analogies are important for how we understand events, beyond equations and tables. Bryan makes this point, with a lovely "elevator pitch" metaphor. Bryan comes up with a good story as well, that I hadn't thought of:

How much has the entry of women to the labor force lowered men's jobs and wages? (I was tempted to write "access to jobs," but someone might take it seriously!)  Should the US government have prohibited women from entering the labor force, in order to shore up the wages of men?

The increase in women's labor force participation was huge -- from 32% to 60%, resulting in an increase in overall labor force participation from 59% to 67% of the population from 1960 to 2000. 8% of 320 million is 26 million, so we're talking about a lot of extra people working.

The answer to the first question is surely yes, but not a lot. 26 million men did not lose their jobs so women could work.  And the answer to the second question is surely no.

FOMC statement and the new normal.

The Sept 17 FOMC statement made the usual waves in the when-will-they-raise-rates commentary. But the separate "policy normalization principles and plans" document is, I think, more interesting. And since  the Wall Street Journal called it "a new technical plan for how it will raise short-term interest rates" and then moved on, it is I think worth a bit of examination.

It confirms the previous plan:
During normalization, the Federal Reserve intends to move the federal funds rate into the target range set by the FOMC primarily by adjusting the interest rate it pays on excess reserve balances. 
What does this mean? The Fed has about $3 trillion of reserves outstanding, and required reserves are about $80 billion. The old way of raising rates would require that they sell off $2.9 trillion of assets, soaking up $2.9 trillion of reserves, so that interest rates will go up without paying interest on reserves. I illustrated this in the graph on the left.

Optimal quantity of money, achieved?

Here are three graphs, presenting inflation, long-term interest rates and short-term interest rates in the US, Germany and Japan.
