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, 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.

Capital and Language

The Fed Scrutinizes Bank Capital, in the Popular Imagination
Fed Governor Dan Tarullo gave important testimony on financial regulation September 9. It got widespread media coverage, for example Wall Street Journal and Bloomberg View.

The good news. The Fed wants more capital. Banks should absorb their own risks, rather than all of us to count on the Fed to stand over their shoulders and make sure they never lose money again.

Confusing language has long been a roadblock in this effort, along with red herrings passed along thoughtlessly.



"Costly"

The WSJ writes
The Federal Reserve plans to hit the biggest U.S. banks with a costly new requirement 
Mr. Tarullo's testimony does not contain any mention of the idea that higher capital requirements will be "costly."  My view, expressed nicely by Admanti and Hellwig's book, is that there is zero social cost to lots more bank equity.  Disagree if you will, but source it please, don't just pass it on as if the source said it or as if this is a fact like the sun coming up tomorrow.

"Hold"

The $20,000 bruise

The $20,000 bruise story in the Wall Street Journal makes good reading. All of these health care disasters make good reading.
 I let the billing supervisor speak for a moment, and then cut him off using the ammo I had acquired from billing-coders' blogs. "You billed a G0390 for trauma-team activation. But chapters 4 and 25 of the MCPM require there be EMS or outside hospital activation if you are billing a G0390. There was no such activation here. So here is what I need you to do: Remove that $10,000 charge and reissue the bill."
He was silent for a moment. And then he said, " Let me talk to my supervisor."
...To the hospital's immense credit, they sent a refund to our insurance company and reissued the bill without the $10,000 trauma activation. They could have refused. What would my recourse have been? To hire a lawyer? Try to interest my insurer in fighting over a measly $10,000 charge? That is a tiny line item in their book of business.
All of us have experienced or know people who have experienced similar nightmares.

A question for any experts who read this blog. Surely there is a business opportunity here, no? "We negotiate your medical bill."  It is a huge waste of resources for Mr. David a "co-founder and chief strategy officer of Organovo Inc., a biotech company in California" to spend hours on the phone and more hours on the internet learning about medicare coding procedures. And all his acquired knowledge  is now wasted. Surely such a business could operate, like many lawyers, on a contingency fee basis, and take a fraction of money saved.

Yes, as Mr. David points out, this is what insurance companies are supposed to do. But copays are going up, and more people are gong to be paying out of pocket anyway.

Are there businesses like this that I, and Mr. David, simply don't know about?

Update: I knew that were there is demand there must be supply! A correspondent sends me a link to copatient.com, which looks like this:


Promotion


Once upon a time, in the Krugman pantheon, I was only "stupid." Then I made it to "mendacious idiot." I've been promoted again, to "Evil!"  And, better, corrupt, since "vested interests can buy the ideas they want to hear," and I am listed a seller.

All under the once-authoritative imprimatur of that impressive logo, reproduced above.  All the news that's fit to print. And then some.

Break out the champagne.  I wonder what I can aspire to next. I do have a Ph.D. Perhaps, dare I hope,...



Actually, I am flattered to be listed in the company of Alesina, Ardagna, Reinhart, Rogoff, and Lucas.  In other contexts, Fama, Prescott, Ferguson.

OK, enough Krugman blogging. It's just gotten to the point of humorous, in a pathetic sort of way.

Cool video



Nightingale and Canary from Andy Thomas on Vimeo.
Using 3D visualization software and other programs, Thomas breaks down photos of insects, orchids, and birds into their composite parts. He then reassembles the images in a sort of collage and builds trippy animations that react, based on rules he's set, to sound – in this case, archival bird song.

This has absolutely nothing to do with economics, or grumpiness. I just thought it was cool.

Krugman on the attack

In the New York Times, rehashing ancient calumnies. It must be a slow day.

Dear Paul, let me introduce you to parts of the distribution other than the mean. Inflation risk is a tail event.  I am in California now. There is a danger of big earthquakes. That the big one has not happened in the last 5 years does not mean the ground will be still forever, nor that geologists are mendacious idiots ignorant of Bayes' theorem.

My worries about inflation do not come from monetary policy. I've been as outspoken on the view that monetary policy is ineffective at the zero bound as the most solid Keynesian.  In the WSJ,  "Reserves that pay market interest are not inflationary. Period." If you bothered to read anything before venting, you'd know that.

My worries stem from the western world at 100% debt to GDP ratio, larger unfunded commitments to ageing populations, slow growth, and no solid plan to pay it back. I've been pretty clear that this is a self inflicted wound -- our governments can let economies grow and pay it back, but may choose not to.  If bond investors decide they don't want to be the ones holding the bag, inflation will come no matter what central banks do about it.

This mechanism remains a proper fault sitting underneath us. But one that can sit a long time. Just like, I hope, the San Andreas.  But the fact that sovereign debt must eventually be repaid, defaulted on, or inflated away, remains an accounting identity valid even in the most rabid Keynesian worldview.

For fun, I spent a few minutes googling Krugman and deflation (sometimes "spiral", sometimes "vortex"), which also did not happen, and in my view cannot happen.  But I will resist. It's just too easy to play this game. Economics is not soothsaying, and descending further into the pit dignifies it unneccessarily.

Italian deflation?

Giulio Zanella has a nice post on noisefromamerika, dissecting the sources of Italian deflation. (In Italian, but Google translate does a pretty good job.)  Deflation can come from lack of "demand," or from technical innovation and increases in supply. What do the data suggest?

After Dodd-Frank



(Youtube link) A talk given at the Mercatus Center / CATO conference "After Dodd-Frank: The Future of Financial Markets." (The link has videos of the whole conference.) The talk is taken from the paper "Towards a Run-Free Financial System," which answers many objections you may have to claims in the talk. (Yes, I have plugged it before on the blog and will likely do again.)

The more I read about it, the more I think it's important to define what is not a problem, and can be left alone. If we have to solve housing subsidies, Fannie and Freddie, global imbalances, Wall Street greed, compensation, inequality, savings gluts, predatory lending, financial utilities, bankruptcy law, behavioral biases of equity managers, living wills, stress tests, capital ratios, Basel regulation, macroprudential bubble-detection and pricking, complexity of derivatives, exchange vs. otc trading, and so on and so on just to save ourselves from the next crisis, we might as well give up now.

Liquidity and IOR

Re: the big balance sheet and how it improves financial stability.

Rodney Garratt, Antoine Martin, and James McAndrews at the New York Fed have a very nice post, Turnover in Fedwire Funds Has Dropped Considerably since the Crisis, but It’s Okay.

Before the crisis, banks held about $50 billion of reserves at the Fed. That's not a lot of money. When banks want to pay each other -- say you write a check to me, so my bank has to get money from your bank -- they do it by transferring reserves through the Fedwire.  So, that's why banks keep some reserves there.

But $50 billion is tiny compared to $10 trillion of M2, and banks use reserves to clear financial transactions too. A huge amount must flow by passing around these tiny reserves. How did banks do it? What happens if bank B says to bank A, "send us $10 million" and bank A didn't have $10 million left at that second in reserves?

Answer: "intraday overdrafts." The Fed would lend bank A the $10 million -- just flip a switch and put $10 million in their reserve account, and call the loan an asset corresponding to this liability. A then pays B, and works hard to make sure that it collects $10 million from C and D by the end of the day.

Krugman on housing

I generally don't read Paul Krugman -- bad for the blood pressure -- and I even less often respond -- don't dignify the insults or feed the trolls. But I took a long plane flight yesterday, and the Times was all I had to read, so I stumbled across his column on housing.

After getting through the customary political barbs at Republicans (Rick Perry in this case), and snarky insults ("the habit economists pushing this line have of getting their facts wrong"), I found something almost sensible.

People, especially "middle class" people,  are moving away from New York and to California, and to Texas and Georgia. Nominal wages in Texas and Georgia are not higher. So why do they move? Answer: Real wages are a lot higher, because the cost of living is so much less. It's practically like moving to a foreign country (in  many ways!). You are earning $100,000 in the un-hip part of Brooklyn, they offer you 80,000 zingbats to move to Truckgunistan. Is it a good deal? Well, you get two dollars per zingbat, so sure!

IOR caused the recession!

Apparently saying something nice about the Fed last week stepped over some bright line somewhere.
Lois Woodhill, writing at Forbes.com, wrote one of the most unintentionally hilarious rebukes here.

Source: Louis Woodhill at Forbes.com


The above chart
...shows what happened the last time the Fed raised the IOR rate [to 0.25%] (remember, it was zero for 95 years). 
The plunge in velocity overwhelmed the Fed’s frantic money creation during the period immediately after it started paying IOR.  NGDP tanked, taking RGDP and employment with it. 
Look, something caused the economic collapse of 2008-2009.  Given the evidence, IOR looks a lot like a man caught at a murder scene with a smoking gun in his hand.
Interesting.  Interest on reserves caused the recession!

Musgrave on 100% reserves

In a comment on an earlier post, Ralph Musgrave pointed to his interesting new paper on 100% reserve banking.

I haven't read the paper yet, but I love the Table of contents, reproduced partially below.

The name "narrow Banking" or "full reserve banking" needs improvement. It's really very wide banking -- so long as the banking is funded by equity or long-term debt. To say "narrow" is almost a fallacy in itself, and perpetuates the fallacy that bank lending will dry up. Maybe "Equity financed banking" or "full reserve deposit taking" would be better. Can anyone think of a name that is both sexy and accurate?

Musgrave's Fourty-four fallacies regarding full reserves:

Section 2: Flawed arguments against FR. .............................. 36
1. FR limits the availability of credit? ................................................................. 36
2. Central bank money is not debt free?............................................................ 38
3. Bank capital is expensive for tax reasons?.................................................... 38

A Few Things the Fed Has Done Right

WSJ Oped, here.
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  ...
I like the large balance sheet and market interest on reserves. I just want them to be permanent, not additional tools for Fed discretionary policy.

I'll post the whole thing in 30 days.

The Oped builds on a new paper, Monetary Policy with Interest on Reserves, and on Toward a Run-Free Financial System. In the latter, I advance the idea that the Fed and Treasury should first offer interest-paying money, and then stamp out private substitutes, just as the US first offered banknotes and then stamped out run-prone substitutes in the 19th century. Interest on reserves, a big balance sheet,  and opening reserves to all are a first step.

Lazear on Labor

Ed Lazear has a very nice short column, Job Turnover Data Show Lots Of Churning, Little Job Creation on Investor's Business Daily.

Modern labor economists see employment and unemployment as a search and matching process with a lot of churn. The popular impression, echoed in most media discussion, is that there is a fixed number of jobs, and people just wait around for more jobs to be "created." That's what it may feel like to an individual, but that's not how the economy works. Lazear's column puts in one very short space some of the better ways to think about unemployment.

The central fact of labor markets is huge churn, not a fixed number of lifelong jobs:
