Technology and the decline in the U.S. labor share of income

A well-known “stylized fact” in economics holds that the distribution of income between labor (wages and salaries) and capital (stocks and bonds) is fairly stable over time. Yet quite a number of researchers find that the share of income going to labor has been on the decline over the past several decades—the most famous, of course, being Thomas Piketty in his book “Capital in the 21st Century.”

Whether this change is as a result of changes in technology is hotly debated in economic circles. Last week, Dylan Matthews at Vox reviewed the research on the question of the labor share, noting that researchers posit a variety of hypotheses, among them the financialization of the U.S. economy, which benefits the owners of capital over wage earners, the downward pressure in U.S. wage brought about by globalization, the decline of labor unions, and the growing accumulation of capital.

But one hypothesis—what Matthews calls “robots”—now garners the most attention. Research by the University of Chicago’s Loukas Karabarbounis and Brent Neiman finds that the decline in the price of investment goods, such as computers or industrial robots, has led to the decline in the labor share of income. Firms have responded to this price decline by substituting capital for labor, meaning firms are investing more in technology and less in the size and remuneration of their workforces.

This result implies a high level of “elasticity of substitution,” or the ability to substitute one type of input for another in the making of a good or the delivery of a service. The two researchers calculate this elasticity between capital and labor at approximately 1.25, which is high compared to previous estimates of the elasticity. To put this number in context, when the elasticity is higher than 1, a decrease in the price of capital would reduce the labor share of income. And if it’s below one, the labor share would increase after a decrease in the price. The authors find that the elasticity results also hold after accounting for the depreciation of capital goods, which is important because the rate of depreciation has accelerated in recent years.

But labor’s share of income can decline without the elasticity of substitution being so high. Research by economists Ezra Oberfield of Princeton University and Devesh Raval at the Federal Trade Commission take a different approach and find a much smaller elasticity while still seeing a decline in labor’s share of income. In Oberfield and Raval’s model, there are two ways for labor’s share to decline. The first is for the price of a factor of production (labor or capital) to decline.  Karabarbounis and Neiman’s research finds that the price of capital has declined and that explains the decline in the labor share.

The other option is that technology has changed so much that capital is more productive now when invested in new technology so more firms are investing in technology at the expense of labor. Oberfield and Raval’s research finds this second option is more important. Whereas Karabarbounis and Neiman look at changes in labor’s share of income across the United States to find their elasticity of 1.25, Oberfield and Raval use data from individual firms to estimate an elasticity for the entire economy. They find a far lower elasticity of about 0.7.

So Oberfield and Ravel argue that what’s causing the decline in labor’s share of income isn’t cheaper capital or more capital accumulation but rather a technological shift toward using capital more. What’s interesting is they say the cause is technology, which they broadly define to include the offshoring of jobs. For these two authors, the technology required to offshore production is a form of capital substitution for labor in the United States, yet they also point out their results don’t point toward a simple offshoring story. What’s happening is quite nuanced, they argue, involving investments in new technology and new workers overseas.

Is this new research just a distinction without a difference? Not at all. Our understanding of how technology is changing our economy, the causes of rising inequality, and the proper policy responses are all influenced by the outcomes of this kind of research. So believe it or not, whether one economic variable is larger or smaller than 1 has quite a bit of impact.

A welcome jolt to the labor market

The U.S. Bureau of Labor Statistics yesterday released the Job Openings and Labor Turnover Survey data for November 2014. This most recent set of data contains information on labor market dynamics, including data on hires, quits, layoffs, and job openings. While the data lag behind the well-covered jobs report by a month, the JOLTS report is another piece of evidence that the U.S. labor market recovery is continuing apace. And while several weaknesses are evident in the data, the overall picture is encouraging.

The new JOLTS data contain several good signs for the labor market. One is that labor market slack is on the decline. According to the data, the ratio of unemployed workers to job openings fell to 1.8 to 1. That means for every job opening, there are 1.8 unemployed workers potentially available to fill it. This ratio was fallen dramatically since the depths of the recession in July 2009 when the ratio was 6.8. Some of this decline is due to discouraged workers leaving the labor force and therefore not counting as unemployed, but the number of openings has also significantly increased recently.

At the same time, the hiring rate and the opening rate for the labor market are near their pre-recession levels. Employers are posting jobs at about the same rate they were before the Great Recession began in December 2007.

But the report isn’t all sunshine. Some shadows are still hanging over the labor market.

One problem is that workers aren’t quitting their jobs at a high rate. Large numbers of workers quitting their jobs can be a very good sign for the labor market. For the most part, workers do not quit their jobs unless they think they can get another job fairly quickly. So an increase in the number of workers quitting is a sign of confidence in the overall labor market. The quits rate in November was 1.9 percent, according to the JOLTS data, below the pre-recession level of about 2.2 percent. Yet the rate has been increasing recently and is up significantly from its recession-level low of 1.3 percent during 2009.

Given the new data, the other issue is movement in the so-called Beveridge Curve. This curve depicts the relationship between the job opening rate and the unemployment rate. After a recession, the labor market is supposed to move along the curve as more jobs are offered and the unemployment rate declines. But during this recovery the unemployed rate is still quite high given the jobs opening rate.

This lack of movement is most likely due to the historically high levels of long-term unemployment, as research by economists Rand Ghayad and William Dickens of Northeastern University shows. This is a problem in one of two ways: Either people are trapped out of the labor force forever or growth isn’t strong enough to get them back in just yet.

Of course, these JOLTS data only go up to November of last year. The December jobs data shows a fall in the unemployment rate so we may see some movement when the JOLTS data for December are released next month.

As these two issues show, problems still abound in the U.S. labor market. But looking at this data release in conjunction with other data, the labor market is healing. A year or so ago, anyone looking at the labor market couldn’t say that confidently. Now, while the labor market seems to have decidedly left that very shaky period, the next test will be to see if the pace of healing can actually accelerate.

    “The Calvo Phillips Curve has a very special property: the subset of firms that change their prices in any period is a perfectly representative sample of all firms… [that] makes the Calvo Phillips Curve very easy to use, which is why macro modellers like to use it. But that property stacks the modeller’s deck in favour of inflation targeting and against NGDP targeting. Because it makes deviations of inflation from target a perfect signal of monetary disequilibrium…. Inflation targeting has such desirable welfare properties… [because] the firms that can change prices do exactly what the firms that cannot change prices would like to do…. Real world central banks know… some prices are stickier… pay more attention to core inflation… ‘target the stickiest price’ is the slogan that captures this idea…. Fluctuations in inflation are a noisy signal of monetary disequilibrium, because the firms that do change prices are not always representative of the firms that don’t. And by targeting inflation the central bank makes inflation stickier, and this reduces inflation’s signal/noise ratio. Fluctuations in output are also a noisy signal…. NGDP targeting is unlikely to be exactly optimal, but may well be better than inflation targeting, which puts all the weight on one noisy signal and ignores the other…. The big puzzle of the recent recession is why the inflation guard dogs failed to bark…. The NGDP guard dogs barked loud and clear, giving a consistent and correct signal. That is what we need to model. And if we can model that, we may also have a model in which targeting NGDP can do better than targeting inflation. But we will need to move away from the Calvo Phillips Curve to build that model. Which is going to make it harder.”

    Why Women Stay Quiet at Work:
    “YEARS ago, while producing the hit TV series ‘The Shield,’ Glen Mazzara noticed that two young female writers were quiet during story meetings. He pulled them aside and encouraged them to speak up more. Watch what happens when we do, they replied. Almost every time they started to speak, they were interrupted or shot down before finishing their pitch. When one had a good idea, a male writer would jump in and run with it before she could complete her thought…. We’ve both seen it happen again and again. When a woman speaks in a professional setting, she walks a tightrope. Either she’s barely heard or she’s judged as too aggressive. When a man says virtually the same thing, heads nod in appreciation for his fine idea. As a result, women often decide that saying less is more…. This speaking-up double bind harms organizations by depriving them of valuable ideas…. The long-term solution to the double bind of speaking while female is to increase the number of women in leadership roles…. When President Obama held his last news conference of 2014, he called on eight reporters — all women. It made headlines worldwide. Had a politician given only men a chance to ask questions, it would not have been news; it would have been a regular day. As 2015 starts, we wonder what would happen if we all held Obama-style meetings…. Doing this for even a day or two might be a powerful bias interrupter…. We’re going to try it to see what we learn…”

In this place, men and women from all times and places set to making a place for the children whom they will raise to be philosopher kings…. The children of the Just City are then inducted into the Platonic system of education and indoctrination. And here is where Walton shines… the small and hurtful and glorious business of interpersonal relationships… the incredible beauty and the cruelty of utopian projects. Nobody writes like Walton. The Just City manages to both sympathize with social engineering at the same time as it demolishes paternalistic solutions to human problems.

    Robert Samuelson Credits Reagan for the Volcker Disinflation:
    “We can go back to a 1986 discussion from Tom Redburn: ‘President Reagan’s four appointees as governors of the Federal Reserve Board prodded Fed Chairman Paul A. Volcker toward a less restrictive monetary policy when they outvoted him last month on a cut in a key interest rate charged to financial institutions, sources said Tuesday.’ The people that President Reagan was appointing to the Federal Reserve did not agree with the Volcker majority and eventually garnered enough influence to force a less restrictive monetary policy. I offer this not as a criticism of President Reagan as some of us loathed the severity of Volcker’s tight monetary policy. But people like Samuelson heart both Reagan and tight monetary policies. Faced with the inconsistency of these two positions–they decide to rewrite history. Update: Dean Baker has more on this including a nice graph of inflation that undermines this line from Samuelson: ‘Worse, government seemed powerless to defeat it.’ Never mind that Dean’s graph shows inflation fell when the FED did tight money under Nixon and again fell after Gerald Ford started up with those damn WIN buttons.”

Bernie Sanders (I-VT) is poised to break dramatically from traditional Democratic views on budgeting, from Obama to Clinton to Walter Mondale and beyond. His big move: naming University of Missouri – Kansas City professor Stephanie Kelton as his chief economist. Kelton is not exactly a household name, but to those who follow economic policy debates closely, tapping her is a dramatic sign. For years, the main disagreement between Democratic and Republican budget negotiators was about how to balance the budget — what to cut, what to tax, how fast to implement it — but not whether to balance it. Even most liberal economists agree that, in the medium-run, it’s better to have less government debt rather than more. Kelton denies that premise…”

Second, welfare economics needs to be toughened up for the rugged landscape revealed by peering into people’s minds. Third, the statement ‘The data are endogenous’ needs to become not only an econometrician’s warning but also a motto reminding economists that new surveys can be designed and new data of many kinds can be collected to answer pressing questions.”

Afternoon Must-Read: John Plender: Bewitched by Mandarins of Central Banking

Graph 10 Year Treasury Constant Maturity Rate FRED St Louis Fed

The very sharp John Plender makes what is now the standard–but I believe incoherent–argument that central banks are doing bad things with quantitative easing and need to reverse it and raise interest rates. They need to do so, Plender thinks, even though doing so will reduce spending, raise unemployment, put downward pressure on wages and prices, and increase risk in a world that still appears to be grossly short of risk bearing capacity. So it is natural to ask: “Why?” What is the upside supposed to be? Is there an upside aside from believing that this will make it easier for investment managers to report black rather than red numbers to their clients while still holding safe Treasury bond-based portfolios?

That Plender’s argument is incoherent is, I think, demonstrated by the fact that markets do not respond as he thinks he should–he saw the end of large-scale US QE coming at the start of 2013, and confidently predicted a fall in US Treasury bond prices that simply has not happened.

The way I see it is this: The root problem is an inability of financial intermediaries to stand behind or to credibly assess risks, and so a reluctance on the part of investors to provide the factor of production of risk-bearing to the marketplace. Pushing safe interest rates way, way, way down and then pushing the supply of risk-free assets that the private sector can hold way, way, way down provides a form of Dutch courage to otherwise reluctant investors: even though they don’t trust financial intermediaries’ risk assessments, the low rates on and low volumes of safe assets give them no alternative. The long-run problems are twofold: First, safe interest rates expected to be very low for a long time artificially boost the value of long-duration assets–so capital is misallocated and we wind up with a capital structure that has in it too many long-duration relatively-safe projects that make at best very small contributions to societal well-being. Second, the demand for risky assets just generated is not a well-based demand for soundly-analyzed risks but rather for any priced risk at all–so the market becomes vulnerable to Ponzi and near-Ponzi finance.

From my point of view, however, the proposed cure of higher unemployment, lower demand, and greater fundamental risk from continued and deeper depression is worse than the disease. First best would be fixing the credit channel so that financial intermediaries would be able to stand behind risks they have credibly assessed. Second best is having the government take over and be a financial intermediary–have it borrow and spend, accepting that its spending will to a certain degree follow a political logic of greasing powerful and squeaky wheels more than amplifying wealth. Third best is continuing QE. Worst is attempting to revert to normal interest rates without financial policy to fix the credit channel or fiscal policy to maintain demand near normal-employment levels.
