What Determines Productivity?

By Chad Syverson

Economists have shown that large and persistent differences in productivity levels across businesses are ubiquitous. This finding has shaped research agendas in a number of fields, including (but not limited to) macroeconomics, industrial organization, labor, and trade. This paper surveys and evaluates recent empirical work addressing the question of why businesses differ in their measured productivity levels. The causes are manifold, and differ depending on the particular setting. They include elements sourced in production practices—and therefore over which producers have some direct control, at least in theory—as well as from producers’ external operating environments. After evaluating the current state of knowledge, I lay out what I see are the major questions that research in the area should address going forward.

Job Loss in the Great Recession: Historial Perspective from the Displaced Workers Survey, 1984-2010

by Henry S. Farber  -  #17040 (LS)

The Great Recession from December 2007 to June 2009 is associated with a dramatic weakening of the labor market from which the labor market is now only slowly recovering.  The unemployment rate remains stubbornly high and durations of unemployment are unprecedentedly long.  I use data from the Displaced Workers Survey (DWS) from 1984-2010 to investigate the incidence and consequences of job loss from 1981-2009.  In particular, the January 2010 DWS, which captures job loss during the 2007-2009 period, provides a window through which to examine the experience of job losers in the Great Recession and to compare their experience to that of earlier job losers.  These data show a record high rate of job loss, with almost one in six workers reporting having lost a job in the 2007-2009 period.  The consequences of job loss are also very serious during this period with very low rates of reemployment, difficulty finding full-time employment, and substantial earnings losses.

Policies to Encourage Job Creation: Hiring Credits vs. Worker Subsidies

by David Neumark – #16866 (LS)

The Great Recession has spurred interest in policy efforts to spur job creation. This article surveys existing research on two “direct” job creation policies: subsidies to employers to hire workers (“hiring credits”); and subsidies to individuals to enter the labor market (“worker subsidies”). The research suggests that in the short-term, when recovery from the recession is a priority, hiring credits are likely a more effective policy response. First, hiring credits are likely more cost effective, as long as they focus on the recently unemployed and create incentives for new job creation. Second, in general, worker subsidies better target benefits to low-income families and especially single mothers. At this juncture, however, because the recession fell so heavily on men, a hiring credit focused on the unemployed may target low-income families well, and the usual distributional concern with low-income female-headed households may be less paramount. And third, employment subsidies may not be as effective when there is high cyclical unemployment. In the longer-term, however, when the labor market has recovered more from the recession and the focus can shift to longer-standing employment problems and distributional concerns, greater reliance on worker subsidies may do more to increase employment while shifting the distribution of benefits more toward lower-income households.

The Capital Structure Decisions of New Firms

This paper finds that startups rely heavily on external debt sources such as bank financing, and less extensively on friends and family-based funding sources. I’m curious whether the latter includes loans collateralized by real estate.

NBER Digest:

In The Capital Structure Decisions of New Firms (NBER Working Paper No. 16272), co-authors Alicia Robb and David Robinson investigate the capitalization choices that firms make in their initial year of operation. Using a novel dataset that tracks firms’ funding decisions through their early years of operation, they find that these firms rely heavily on external debt sources such as bank financing and less extensively on friends and family-based funding sources.

There is a widely held view that frictions in capital markets prevent startup firms from achieving their optimal size, or indeed, from starting up at all. That view implies that startups are likely to pursue financing from informal channels. But Robb and Robinson find that funding through the use of formal debt dwarfs funding from friends and family: the average amount of bank financing is seven times greater than the average amount of insider-financed debt. Moreover, three times as many firms rely on outside debt as inside debt. This reliance on formal credit channels as opposed to personal credit cards and informal lending even holds true for the smallest firms in the sample at the earliest stages of their founding.

These findings are robust to controls for credit quality, industry, and characteristics of the business owner. Nonetheless, the authors do find that women are somewhat less likely to acquire outside debt. Also, black-owned businesses have a lower ratio of outside-to-inside financing. Businesses started by individuals without a high school degree also rely more on inside financing than others.

Extending their analysis, the authors find that a capital structure that is more heavily tilted towards formal credit channels is associated with a greater likelihood of success for the new firm. Firms that ceased operations within three years not only began smaller but also had considerably smaller proportions of outside debt-to-total capital. Moreover, capital structure decisions are especially important in the initial years: firms that accessed more external debt in the initial stages were nearly 10 percent more likely to be in the top revenue group. Even if credit conditions in 2004 — the first year of the data set — were unique, credit market access appears to have had an important impact on firm success.

The authors conclude that the heavy reliance on external debt underscores the importance of well functioning credit markets for the success of nascent business activity. Because startups rely so extensively on outside debt as a source of startup capital, they are especially sensitive to changes in bank lending conditions.

On the Persistent Financial Losses of U.S. Airlines: A Preliminary Exploration

by Severin Borenstein  -  #16744 (IO EFG)

U.S. airlines have lost nearly $60 billion (2009 dollars) in domestic markets since deregulation, most of it in the last decade.  More than 30 years after domestic airline markets were deregulated, the dismal financial record is a puzzle that challenges the economics of deregulation.  I examine some of the most common explanations among industry participants, analysts, and researchers — including high taxes and fuel costs, weak demand, and competition from lower-cost airlines.  Descriptive statistics suggest that high taxes have been at most a minor factor and fuel costs shocks played a role only in the last few years.  Major drivers seem to be the severe demand downturn after 9/11 — demand remained much weaker in 2009 than it was in 2000 — and the large cost differential between legacy airlines and the low-cost carriers, which has persisted even as their price differentials have greatly declined.

Calorie Posting in Chain Restaurants

by Bryan Bollinger, Phillip Leslie, and Alan Sorensen

We study the impact of mandatory calorie posting on consumers’ purchase decisions using detailed data from Starbucks. We find that average calories per transaction fall by 6 percent. The effect is almost entirely related to changes in consumers’ food choices—there is almost no change in purchases of beverage calories. There is no impact on Starbucks profit on average, and for the subset of stores located close to their competitor Dunkin Donuts, the effect of calorie posting is actually to increase Starbucks revenue. Survey evidence and analysis of commuters suggests the mechanism for the effect is a combination of learning and salience. (JEL D12, D18, D83, L83)

Updated drafts of markup and industry papers

We have posted updated drafts of our markup paper and our industry evidence paper.

In our markup paper, “The Cyclical Behavior of the Price-Cost Markup,” we re-estimated our marginal change in overtime hours using microdata from my Londitudinal Population Databse (LPD). We still find that markups are procyclical or acyclical, both unconditionally and conditional on demand shocks.

In our industry paper, “Industry Evidence on the Effects of Government Spending,” we significantly updated the theory and discussion, explored other industry characteristics associated such as unionization and concentration, and added analysis of the dynamic interactions. We now discuss how the growth of government spending across industries is correlated with technology and show how accounting for this correlation is essential for constructing a proper instrument for government demand.

Copies of either paper can be downloaded from my research page.

Updated version of markup paper

We have updated our working paper, “The Cyclical Behavior of the Price-Cost Markup.” This version will presented at the 2010 International Research Forum on Monetary Policy on March 26-27, 2010.

Updated version of industry evidence paper

We have updated our working paper, “Industry Evidence on the Effects of Government Spending.” Using a slightly different instrument for government demand, we now find that an increase in government demand raises output and hours but lowers real product wages and productivity, consistent with the neoclassical model of government spending.

Industry Evidence on the Effects of Government Spending

Valerie Ramey and I have posted a draft of our new working paper, “Industry Evidence on the Effects of Government Spending,” which we will be presenting at the AEA meetings this weekend. In it we study how industry-level government spending effects output, hours, wages, and productivity.

This paper investigates industry-level effects of government purchases in order to shed light on the transmission mechanism for government spending on the aggregate economy. We begin by highlighting the different theoretical predictions concerning the effects of government spending on industry labor market equilibrium. We then create a panel data set that matches output and labor variables to shifts in industry-specific government demand. The empirical results indicate that increases in government demand raise output and hours, but have no effect on real product wages, even over a five-year horizon. Government demand also appears to raise productivity and markups when they are measured using gross output. These results are inconsistent with standard neoclassical and New Keynesian models of government spending.
