The changing calculus of labor market churn

The Wall Street Journal’s Josh Zumbrun today highlights the decline in labor market churn, or the amount of movement in the labor market as workers quit jobs, get laid off and are hired for new jobs in the United States. Zumbrun points out that the decline in churn can be particularly damaging for young workers. Moving from job to job is a large driver of wage growth for young workers. But given the long-term trends in labor market churn, perhaps this new level of churn is the new normal.

With the onset of the Great Recession, labor market churn declined quite a bit. According to data from Bureau of Labor Statistics’s Job Openings and Labor Turnover Survey, the jobs-hire rate and the quits rate—both signs of positive job churn—are below their pre-recession levels. But the decline in job churn started long-before December 2007, the official start of the recession.

The decline in mobility between jobs has puzzled economists and continues to do so. But one recent paper offers an interesting and simple explanation for the decline in churn—the benefits of getting a new job might have gone down.

The working paper by economist Raven Molloy and Christopher Smith of the Federal Reserve Board of Governors and Abigail Wozniak of the University of Notre Dame actually seeks to understand the decline in inter-state mobility as it relates to the decline in churn. They found that the decline in Americans moving across state borders is due to the decline in workers switching jobs. So understanding the decline in job switching will explain the decline in moving to a new state.

The authors look at several explanations for why job movement might have declined, such as changes in where jobs are located across the country, increasing job polarization and difficulty in switching jobs because of having two working parents. But they find all of these explanations lacking. The hypothesis that they do come up with is that the return to switching jobs appears to have declined. The gains to staying at one employer hasn’t changed over time, but something has changed that makes moving to a new employer less attractive.

Molloy, Smith, and Wozniak speculate that the decline in this value has to do with two trends. First, the inequality of pay across business establishments has increased. Secondly, some evidence shows that increasingly high-skilled workers are employed by high-pay establishments and lower-skilled workers by lower-pay establishments. If these workers are already “well-matched” then there could be a risk of moving to a new employer.

The authors, however, are very clear that their hypothesis and dual explanation are speculative. And of course, the research is only at the working paper stage. But if this explanation holds up then our understanding of the labor market might need some updating. Our economy may be just as dynamic as in the past, but without the labor market churn we’ve seen in the past. Horace Greeley may have been right in the past, but in the future economists and policymakers need to better understand this new job-churn situation.

Morning Must-Read: Simon Wren-Lewis: Macroeconomists, Not Bankers, Should Set Interest Rates

Simon Wren-Lewis: Why macroeconomists, not bankers, should set interest rates: “[The] interest rate… which closes the output gap…

[maintains] the level of output and unemployment that will keep underlying inflation constant… [is] the Wicksellian natural rate…. But, respond[s]… the BIS… monetary policy cannot afford to ignore the financial sector, and the risk of excessive lending and bubbles…. The implication is that a financial crisis only happens because interest rates are set at the wrong level…. The… deregulation of the financial sector in the decades before?–not an issue. The widespread misselling of subprime mortgages?–these things happen. All the other examples of misselling and fraud?–boys will be boys. An industry that profits from a massive implicit public subsidy?–we see no subsidy. Classifying subprime products as AAA? Massive increases in bank leverage in the 00s?–all the result of keeping interest rates too low. When those putting the BIS case tell you that macroprudential controls (a.k.a. financial regulations) are ‘untested’ and ‘uncertain in their impact’, what they are really saying is that the financial system cannot be regulated to make it safe when interest rates are low….

I like to praise the current UK government when I can. In setting up a Financial Policy Committee that is separate from the Monetary Policy Committee they did exactly the right thing. This formalises an assignment: macro prudential policy to control financial sector excess, and interest rates to control demand and inflation. Most macroeconomists know this makes sense. But the financial sector has a pecuniary interest in pretending otherwise. Those that get too close to that sector should be kept well away from setting interest rates.

Morning Must-Read: Noah Smith: Should the Fed Crash Now to Prevent a Crash Later?

Noah Smith: Should the Fed crash the economy now to prevent a crash later?: “To many, the implication is clear: The Fed needs to raise interest rates in order to prevent a destabilizing market crash. That isn’t a good idea…. Higher asset prices due to lower safe interest rates aren’t some kind of nefarious plot–this is just Finance 101…. That’s rational price appreciation, not a bubble…. When practically everyone is convinced that asset prices are relatively high, like now, it’s pretty obvious that there aren’t many greater fools out there. If you look at past bubbles, such as the late-’90s tech bubble or the mid-2000s housing bubble, you see that there was always a large contingent of society that thought it wasn’t a bubble at all…. Who nowadays thinks that there’s some special Big New Thing that’s going to push stocks and bonds and commodities all to stratospheric heights forever?…. I say we hold off on our calls for anti-bubble rate hikes.

Evening Must-Read: Nick Rowe: Siimple Arithmetic for John Taylor’s Mistaken Legislated Rule

Nick Rowe: Some simple arithmetic for mistakes with Taylor Rules: “If you see your neighbour thinking of doing something daft…

…apparently unaware of one of the problems, you ought to speak up. Especially if it will affect you too, because you do a lot of trade with your neighbour. A fixed Taylor Rule… makes the danger of hitting the ZLB bigger than you think it is. And Taylor Rules don’t work at the ZLB…. What happens if you are wrong about the natural rate of interest, or wrong about potential output?… If actual potential output is one percentage higher than you think it is, that makes you set the nominal rate 0.5 percentage points too high, and so inflation would need to be 0.33 percentage points too low on average to have a big enough offsetting effect to cancel out your mistake…. For a normal central bank, that is a problem, but it is not a big problem…. They fix mistakes in their Taylor Rule as they go along…. That’s probably the main reason why we always observe a lagged interest rate in the equation when we estimate a central bank’s reaction function…. But if the parameter values of the Taylor Rule are fixed by law, central banks are not allowed to learn from their mistakes…. If you really really want to legislate a Taylor Rule, OK. But there’s a price you must pay, if you want to maintain the same margin of safety against hitting the ZLB. That price is a higher average rate of inflation built right into that legislated Taylor Rule. Your choice: legislated Taylor Rules; hitting the ZLB more frequently; a higher rate of inflation. Pick any two…”

  1. Kevin Drum: Economic Growth Looks Pretty Grim These Days: “The glass-half-full view is: Whew! That huge GDP drop in Q1 really was a bit of a blip, not an omen of a coming recession. The economy isn’t setting records or anything, but it’s back on track. The glass-half-empty view is: Yikes! If the dismal Q1 number had really been a blip, perhaps caused by bad weather, we’d expect to see makeup growth in Q2. But we’re seeing nothing of the sort. We lost a huge chunk of productive capacity in Q1 and apparently we’re not getting it back…. I am, by nature, a glass-half-empty kind of person, so feel free to write off my pessimism about this.

The challenge Clinton faces in channeling the current populist mood without alienating her longtime Wall Street benefactors…. A nugget that brought that ‘consensus’ line immediately back to mind… ‘We’re all in this mess together’, the mess being taxes, financial regulation, and economic growth…. This is apparently how Clinton frames the discussion these days. It is, to say the least, discouraging. The only other time I’ve heard people use words like ‘consensus’ and ‘in this together’ during conversations about financial regulation was while talking to Wall Street executives…. Has Hillary picked up this line because she’s spent too much time in the company of well-heeled corporate types?…”

The following statement was adopted unanimously by the editorial board of the journal, and reproduced here in full: “We wish to endorse, in its entirety and without reservation, the recent essay ‘On the Emptiness of Failed Replications’ by Jason Mitchell. In Prof. Mitchell’s field, scientists attempt to detect subtle patterns of association between faint environmental cues and measured behaviors, or to relate remote proxies for neural activity to differences in stimuli or psychological constructs. We are entirely persuaded by his arguments that the experimental procedures needed in these fields are so delicate and so tacit that failures to replicate published findings must indicate incompetence on the part of the replicators, rather than the original report being due to improper experimental technique or statistical fluctuations. While the specific obstacles to transmitting experimental procedures for social priming or functional magnetic resonance imaging are not the same as those for reading the future from the conformation and coloration of the liver of a sacrificed sheep, goat, or other bovid, we see no reason why Prof. Mitchell’s arguments are not at least as applicable to the latter as to the former. Instructions to referees for JEBH will accordingly be modified to enjoin them to treat reports of failures to replicate published findings as ‘without scientific value’, starting immediately. We hope by these means to ensure that the field of haruspicy, and perhaps even all of the mantic sciences, is spared the painful and unprofitable controversies over replication which have so distracted our colleagues in psychology.’ Questions about this policy should be directed to the editors; I’m just the messenger here…”

Oversharing About Money: An International Financial Wire Transfer from Lafayette, California, USA to Ahero, Nyando District, Nyanza Province, Kenya

J. Bradford DeLong

As I finish the story, the hedge-fund mogul smiles, as he says: “Always watch the bottom tail of what might happen…” And it reminds me of things about myself and the world that make me uneasy…

A few short years ago we lived, for the school district, in Lafayette. Lafayette is close to here in space and time, but distant in attitude. Lafayette is a place an unkind observer based in and comfortable in San Francisco might describe as an unholy mix of the worst parts of northern and southern California. There we had a neighbor, Bie Bostrom. She had been the oldest Peace Corps volunteer in East Africa. She kept in touch with what had been her town: Ahero, population 10K, in Nyando District, Nyanza Province, Kenya. And there she funds and runs a one-elderly-woman one-town NGO with zero administrative overhead: Grandmothers Raising Grandchildren. That’s http://grgahero.org: godzilla-rath of Khan (with an r)-godzilla-alien-hitchhiker-empire strikes back-rath of Khan-omen-dot-omen-rath of Khan-godzilla. No, I’m not going to hit you up–you’ve been hit up already coming here, at the door.

But when we think about HIV and AIDS here in San Franciso, we tend to think locally–and we should think globally as well. HIV and AIDS continues to be the grim reaper of Africa, and it cut an enormous generational swath. Ahero, total population 10K, has orphans in the three figures who had not been adopted by aunts and uncles–if there were any aunts and uncles left alive–but rather left to be raised by their grandmothers. And that is the target population of Bie Bostrom’s one-elderly-woman one-town zero-overhead NGO:

  • The grandmothers weave baskets.
  • Bie carries the baskets back to San Francisco Bay and sells them for $40 each.
  • Bie carries the money back to Ahero, Kenya.
  • Bie hires Moses to oversee what is going on on site.

Moses distributes rice and beans to the grandmothers; disburses school and scholarship money; buys very cute goats–alas! meat goats, for this is not a lactose-tolerant population–and gives them to the families; takes the billy goat–who must think that he has lucked into a very good life indeed–around on a rope from house to house so that there can be more goats; finds proxy cutouts to buy the goats because by now the local goat-dealers rub their hands with glee whenever they see Moses coming. You get the picture. Total monthly expenditure? The very low four figures.

We agree to sponsor a 24-hour basket sale on my website, and to match whatever money is raised. There are at most 50 baskets on hand, after all. But what if websurfing people want to give in addition to the cost of the basket? What if they wish to give without buying a basket? What if weblog commenters begin writing: “This is our opportunity to bankrupt Brad DeLong!!” We, remember, promise to match not basket sales but money raised.

24 hours later we do not–as I thought we would–face a commitment in the low four figures. Rather, we face a commitment in the low five figures. Taking what we had promised and the spike produced by the websurfers, Bie has an extra year’s worth of money, or more, to spend in Ahero to support the grandmothers trying to raise their AIDS-orphaned grandchildren and great-grandchildren.

The thing I discover about myself that I do not like: I find myself writing a check in the low five rather than in the low four figures with a surprisingly bad heart. Given the amount of money that flows through the household, this is really not a big deal at all–less than one-quarter’s college for one child, less than a 1% impact on our current net worth, less than an 0.5% downward move in the Berkeley housing market. Yeshua bar Yusuf would definitely raise an eyebrow, for we are well into “giving of our surplus, not our substance” territory here.

Moreover, the money has the potential to do a lot of good: it is a big deal for Ahero. We are perhaps eight times as well-off as the American median; grandmothers raising AIDS-orphaned grandchildren are less than one-half as well-off as the Kenyan median; the United States is perhaps 100 times as well-off as Kenya; and by the time you multiply those numbers together you conclude that $10K in grassroots contributions plus a $10K match has a relative salience for those to whom it is going in Kenya that is the same as $5M would have for us. And if I cannot set that in motion with a genuinely good heart, what does that say about me?

There remains the question: What to do with the extra money? Bie decides to build a well–and to build a well not out in the fields where it would be useful for irrigating the rice but near the houses. Bie’s view: the girls of Ahero need to go to school–and if you spend up to three hours a day carrying water back to the house, your school attendance is going to be spotty. The local powerbrokers have a different view. Their view: Ahero runs on rice. If there is enough water to grow the rice (and beans), then lots of things are possible. Then everyone can be fed. Then there will be enough labor to grow and process coffee and oilseeds. Then there will be money for teachers. Then there will be time for students to attend school. If there is not enough water…

In the end we play the heavies: the weirdos from Greater San Francisco who believe in education and quality-of-life for girls, rather than investment in productive and badly needed agricultural infrastructure. Is this the right thing to do with the money? We have no idea. Bie strongly thinks it is, but her values are not necessarily their values. And who are the “they” whose values should count anyway?

Thus symbols that were once claims on resources that clients of Fidelity Investor Services once owned have been transferred to us in return for my informing people of my view of likely future Federal Reserve policy, and we now offer to let people in Ahero if they do what we say control those symbols so that internationally-traded goods and services that would otherwise flow around Ahero as if it were not there flow into it, and can be utilized there. This is not economic democracy–the people of Kenya do not decide collectively what to invest in. This is not even local autonomous oligarchy–the power brokers who have successfuly obtained or maintained status in Ahero deciding what to do. This is neo-neo-colonalism: it is (or some of it is) our money, and we decide how it is to be spent.

Once the money is earmarked and sitting in the bank account, how do you get a well dug in western Kenya? We investigate well-digging machines. Ahero is ten miles outside of Kisumu, population 500K, on the road to Nairobi. Ahero is 100 miles from Nairobi, population 3.5M. How costly can it be to get a well-digging machine from Kisumu–or Nairobi–to Ahero along the road and use it to dig the well?

Too costly.

When Bie costs it out, it turns out that we could dig two wells by hand for the cost of hiring one better-funded and larger NGO to dig the well by machine. We can send purchasing power halfway around the globe in less than a second. Once you pack your commodities–durable, non-spoilable–in the container, you can ship them halfway around the world for less than $1/cubic foot. But actually exercising control and getting value-for-money 8K miles away is much more difficult.

I am a neoclassical economist–in fact, I am a card-carrying neoliberal. In my lectures at Berkeley I stress what a marvelous, miraculous, and effective mechanism for coordinating our societal division of labor is our property, contract, exchange, and money-based market economy. I point out that in the 20th century we ran a gigantic natural experiment in which those peoples trapped by politics and the result of war behind the Iron Curtain experimented with eliminating the market economy of self-adjusting equilibrating prices via supply and demand. The consequence was that the really-existing socialist economies threw away 80% of their potential economic productivity by banning the market economy. Even they, however, relied heavily on money and the promise of differential rewards and promotions to positions that offered more money as major incentivizing devices. Those who tried to go beyond Lenin in the direction of “Full Communism”–say, Che Guevara in Cuba and his Ten Million Ton Sugar Harvest campaign and his attempt to divide societies into a vanguard of new men motivated by moral incentives, a mass who were to be educated into being motivated by moral incentives, and los gusanos to be motivated not by carrots but by sticks–either quickly abandoned their dreams or found themselves abandoned by their comrades.

But.

Waving money in people’s faces to try to get them to do what you want is a very narrow-bandwidth communications channel. Even to implement our desire to get goats to the grandmothers, we would be largely out of luck–we would be taken to the cleaners by the local goat-dealers–if we did not have Moses, and if Moses did not have the ability to hire local proxy cutouts to buy the goats for him, and if Moses were not committed enough to the mission to actually care about getting good value for the grandmothers from Bie’s money. If Moses sought, say, to boost his local standing by overpaying people who he thought it would be useful to him to have them owing him favors in the future, we would be in big trouble.

If the well is going to be useful we think we need much more bandwidth and, thus, control over what will actually happen on the ground. This is not uncommon: I remember a conversation I had once with one person active in African development. He told me that he would never in a thousand years have thought that he would find himself spending his time writing policies to prohibit the transport of smoked monkey meat in backseats occupied by visiting foreign dignitaries–no matter how high a price smoked monkey would bring.

But we have Moses on the scene. Thus it turns out to be much more cost-effective to dig the well by hand. Moses hires men with shovels. We find that it is the case that here–or, rather, not here but there–and now, in the twenty-first century, we find that the best way to deploy our intercontinental social power to make this happen is to induce young men with testosterone-fueled muscles and iron shovels–technologies that hit the shores of Lake Victoria 3000 years ago–to dig the well by hand.

In my lectures at Berkeley I talk about how the iron-and-steam technologies of the Industrial Revolution 200 years ago meant that humans could and would no longer add much value by using their large muscles to move heavy things. William Gibson’s famous line is: “the future is here–it is just not evenly distributed”. But he does not say that the present is not evenly distributed here. And even what we regard here as the past of centuries ago is not evenly distributed enough to have made it to rural East Africa, at least not when we try to figure out how to get the best well dug at the lowest cost.

Now when we look at the totals on our quarterly index-fund statements, there is perhaps a difference in the third significant figure. Now if you were to go to Ahero, Nyando District, Nyanza Province, Kenya, you would find an extra well–one located not near the rice fields but in among the houses, with an elderly woman charging pennies for you to fill a bucket. And perhaps you would find a substantial number of additional girls sitting in school rooms rather than walking extra miles with buckets on their heads. And perhaps a substantial number of men and their relatives are grateful to Moses for getting them some money by giving them the opportunity to work on the well.

So a feel-good story, no? But telling it again reminds me that I ought to set this process in motion with a better heart. Telling it again reminds me that we ought not to live in a world in which $20K distributed among AIDS-survivors in Ahero, Kenya has the same salience that $5M has for people like me in Greater San Francisco. And telling it again reminds me that we ought not to live in a world in which we lack the organizational competence to use productive modern rather than less-productive 3000-year-old technologies to dig wells near the shores of Lake Victoria.

Department of “WTF?!” Chris House on Traditional Macroeconomic Models and the Great Recession

Can anyone put forward a credible explanation for this?

Chris House (July 13, 2014): Traditional Macroeconomic Models and the Great Recession: “Commentators like Paul Krugman…

…should also own up to the mounting evidence that the older models (even the paleo-Keynesian models that some prefer) clearly failed…. They made clear predictions about inflation that were supposedly at the center of the New Keynesian mechanism–predictions that never materialized.

Paul Krugman (April 13, 2013): The Missing Deflation: “Keynesians…. One area where things haven’t worked out as [we] expected…

…however, is on the deflation front. Inflation has stayed very subdued; but coming in to the crisis I certainly thought that actual Japanese-style deflation was a real possibility. That hasn’t materialized (and for that matter, even Japan never had more than very gradual deflation). Why?

One possibility was that there wasn’t as much slack in the economy as we thought, that a lot of the problem was structural rather than cyclical.

Another possibility, however, which I at least noted fairly early on, was that downward nominal wage rigidity could explain why the fairly rapid falls in inflation seen in previous slumps weren’t happening this time; if wages are “reluctant” to actually fall, inflation becomes “sticky” at low levels even with a very depressed economy.

So now we have two new analyses, by Hobijn and Daly at a Boston Fed conference, and in the IMF’s new World Economic Outlook, both of which strongly suggest that the issue isn’t structural unemployment, it’s low responsiveness of inflation to unemployment when inflation is low to begin with.

Three points here:

  1. This does say that there is little risk of accelerating inflation. Indeed, Hobijn and Daly suggest that there’s a “pent-up demand for wage cuts” that will probably push inflation lower even if the economy is recovering.

  2. Central banks and other policy makers will be making a terrible mistake if they look at low, stable inflation and pat themselves on the back for a job well done. Low, stable inflation, it turns out, is entirely consistent with catastrophic economic mismanagement.

  3. Notice how Keynesians responded to the partial failure of a prediction: by asking what they got wrong, and how their model of the world needed to be adjusted. This, of course, shows what fools we are: everyone on the other side of these debates knows that you respond to mistakes by never acknowledging them, and doubling down on whatever you originally claimed.
