  The Evolution of U.S. Retail Concentration
  

  March 2022

  Authors: Dominic A. Smith, Sergio Ocampo

  Working Paper Number:

  CES-22-07

  Increases in national concentration have been a salient feature of industry dynamics in the U.S. and have contributed to concerns about increasing market power. Yet, local trends may be more informative about market power, particularly in the retail sector where consumers have traditionally shopped at nearby stores. We find that local concentration has increased almost in parallel with national concentration using novel Census data on product-level revenue for all U.S. retail stores. The increases in concentration are broad based, affecting most markets, products, and retail industries. We implement a new decomposition of the national Herfindahl Hirschman Index and show that despite similar trends, national and local concentration reflect different changes in the retail sector. The increase in national concentration comes from consumers in different markets increasingly buying from the same firms and does not reflect changes in local market power. We estimate a model of retail competition which links local concentration to markups. The model implies that the increase in local concentration explains one-third of the observed increase in markups.

  The China Shock Revisited: Job Reallocation and Industry Switching in U.S. Labor Markets
  

  October 2024

  Authors: Nicholas Bloom, André Kurmann, Kyle Handley, Philip A. Luck

  Working Paper Number:

  CES-24-65

  Using confidential administrative data from the U.S. Census Bureau we revisit how the rise in Chinese import penetration has reshaped U.S. local labor markets. Local labor markets more exposed to the China shock experienced larger reallocation from manufacturing to services jobs. Most of this reallocation occurred within firms that simultaneously contracted manufacturing operations while expanding employment in services. Notably, about 40% of the manufacturing job loss effect is due to continuing establishments switching their primary activity from manufacturing to trade-related services such as research, management, and wholesale. The effects of Chinese import penetration vary by local labor market characteristics. In areas with high human capital, including much of the West Coast and large cities, job reallocation from manufacturing to services has been substantial. In areas with low human capital and a high initial manufacturing share, including much of the Midwest and the South, we find limited job reallocation. We estimate this differential response to the China shock accounts for half of the 1997-2007 job growth gap between these regions.

  The Rise of Specialized Firms
  

  February 2024

  Authors: Lorenz K.F. Ekerdt, Kai-Jie Wu

  Working Paper Number:

  CES-24-06

  This paper studies firm diversification over 6-digit NAICS industries in U.S. manufacturing. We find that firms specializing in fewer industries now account for a substantially greater share of production than 40 years ago. This reallocation is a key driver of rising industry concentration. Specialized firms have displaced diversified firms among industry leaders'absent this reallocation concentration would have decreased. We then provide evidence that specialized firms produce higher-quality goods: specialized firms tend to charge higher unit prices and are more insulated against Chinese import competition. Based on our empirical findings, we propose a theory in which growth shifts demand toward specialized, high-quality firms, which eventually increases concentration. We conclude that one should expect rising industry concentration in a growing economy.

  What Drives Stagnation: Monopsony or Monopoly?
  

  October 2022

  Authors: Lawrence Warren, Shubhdeep Deb, Jan Eeckhout, Aseem Patel

  Working Paper Number:

  CES-22-45

  Wages for the vast majority of workers have stagnated since the 1980s while productivity has grown. We investigate two coexisting explanations based on rising market power: 1. Monopsony, where dominant firms exploit the limited mobility of their own workers to pay lower wages; and 2. Monopoly, where dominant firms charge too high prices for what they sell, which lowers production and the demand for labor, and hence equilibrium wages economy-wide. Using establishment data from the US Census Bureau between 1997 and 2016, we find evidence of both monopoly and monopsony, where the former is rising over this period and the latter is stable. Both contribute to the decoupling of productivity and wage growth, with monopoly being the primary determinant: in 2016 monopoly accounts for 75% of wage stagnation, monopsony for 25%.

  How Firms Respond to Business Cycles: The Role of Firm Age and Firm Size
  

  June 2013

  Authors: John Haltiwanger, Ron Jarmin, Javier Miranda, Teresa C. Fort

  Working Paper Number:

  CES-13-30

  There remains considerable debate in the theoretical and empirical literature about the differences in the cyclical dynamics of firms by firm size. This paper contributes to the debate in two ways. First, the key distinction between firm size and firm age is introduced. The evidence presented in this paper shows that young businesses (that are typically small) exhibit very different cyclical dynamics than small/older businesses. The second contribution is to present evidence and explore explanations for the finding that young/small businesses were hit especially hard in the Great Recession. The collapse in housing prices accounts for a significant part of the large decline of young/small businesses in the Great Recession.

  Labor Market Concentration, Earnings Inequality, and Earnings Mobility
  

  September 2018

  Authors: Kevin Rinz

  Working Paper Number:

  carra-2018-10

  Using data from the Longitudinal Business Database and Form W-2, I document trends in local industrial concentration from 1976 through 2015 and estimate the effects of that concentration on earnings outcomes within and across demographic groups. Local industrial concentration has generally been declining throughout its distribution over that period, unlike national industrial concentration, which declined sharply in the early 1980s before increasing steadily to nearly its original level beginning around 1990. Estimates indicate that increased local concentration reduces earnings and increases inequality, but observed changes in concentration have been in the opposite direction, and the magnitude of these effects has been modest relative to broader trends; back-of-the-envelope calculations suggest that the 90/10 earnings ratio was about six percent lower and earnings were about one percent higher in 2015 than they would have been if local concentration were at its 1976 level. Within demographic subgroups, most experience mean earnings reductions and all experience increases in inequality. Estimates of the effects of concentration on earnings mobility are sensitive to specification.

  The Evolution of National Retail Chains: How We Got Here
  

  March 2015

  Authors: John Haltiwanger, C.J. Krizan, Lucia Foster, Shawn Klimek, Scott Ohlmacher

  Working Paper Number:

  CES-15-10

  The growth and dominance of large, national chains is a ubiquitous feature of the US retail sector. The recent literature has documented the rise of these chains and the contribution of this structural change to productivity growth in the retail trade sector. Recent studies have also shown that the establishments of large, national chains are both more productive and more stable than the establishments of single-unit firms they are displacing. We build on this literature by following the paths of retail firms and establishments from 1977 to 2007 using establishment- and firm-level data from the Census of Retail Trade and the Longitudinal Business Database. We dissect the shift towards large, national chains on several margins. We explore the differences in entry and exit as well as job creation and destruction patterns at the establishment and firm level. We find that over this period there are consistently high rates of entry and job creation by the establishments of single-unit firms and large, national firms, but net growth is much higher for the large, national firms. Underlying this difference is far lower exit and job destruction rates of establishments from national chains. Thus, the story of the increased dominance of national chains is not so much due to a declining entry rate of new single-unit firms but rather the much greater stability of the new establishments belonging to national chains relative to their single-unit counterparts. Given the increasing dominant role of these chains, we dissect the paths to success of national chains, including an analysis of four key industries in retail trade. We find dramatically different patterns across industries. In General Merchandise, the rise in national chains is dominated by slow but gradual growth of firms into national chain status. In contrast, in Apparel, which has become much more dominated by national chains in recent years, firms that quickly became national chains play a much greater role.

  Shareholder Power and the Decline of Labor
  

  May 2022

  Authors: Till von Wachter, Hyunseob Kim, Antonio Falato

  Working Paper Number:

  CES-22-17

  Shareholder power in the US grew over recent decades due to a steep rise in concentrated institutional ownership. Using establishment-level data from the US Census Bureau's Longitudinal Business Database for 1982-2015, this paper examines the impact of increases in concentrated institutional ownership on employment, wages, shareholder returns, and labor productivity. Consistent with theory of the firm based on conflicts of interests between shareholders and stakeholders, we find that establishments of firms that experience an increase in ownership by larger and more concentrated institutional shareholders have lower employment and wages. This result holds in both panel regressions with establishment fixed effects and a difference-in-differences design that exploits large increases in concentrated institutional ownership, and is robust to controls for industry and local shocks. The result is more pronounced in industries where labor is relatively less unionized, in more monopsonistic local labor markets, and for dedicated and activist institutional shareholders. The labor losses are accompanied by higher shareholder returns but no improvements in labor productivity, suggesting that shareholder power mainly reallocates rents away from workers. Our results imply that the rise in concentrated institutional ownership could explain about a quarter of the secular decline in the aggregate labor share.

  Aggregate Productivity Growth: Lessons From Microeconomic Evidence
  

  September 1998

  Authors: John Haltiwanger, C.J. Krizan, Lucia Foster

  Working Paper Number:

  CES-98-12

  In this study we focus on the role of the reallocation of activity across individual producers for aggregate productivity growth. A growing body of empirical analysis yields striking patterns in the behavior of establishment-level reallocation and productivity. Nevertheless, a review of existing studies yields a wide range of findings regarding the contribution of reallocation to aggregate productivity growth. Through our review of existing studies and our own sensitivity analysis, we find that reallocation plays a significant role in the changes in productivity growth at the industry level and that the impact of net entry is disproportionate since entering plants tend to displace less productive exiting plants, even after controlling for overall average growth in productivity. However, an important conclusion of our sensitivity analysis is that the quantitative contribution of reallocation to the aggregate change in productivity is sensitive to the decomposition methodology employed. Our findings also confirm and extend others in the literature that indicate that both learning and selection effects are important in this context. A novel aspect of our analysis is that we have examined the role of reallocation for aggregate productivity growth to a selected set of service sector industries. Our analysis considers the 4-digit industries that form the 3-digit industry automobile repair shops. We found tremendous churning in this industry with extremely large rates of entry and exit. Moreover, we found that productivity growth in the industry is dominated establishment data at Census, the results are quite striking and clearly call for further analysis.

  The Business Dynamics Statistics: Describing the Evolution of the U.S. Economy from 1978-2019
  

  October 2021

  Authors: Martha Stinson, Christopher Goetz

  Working Paper Number:

  CES-21-33

  The U.S. Census Bureau's Business Dynamics Statistics (BDS) provide annual measures of how many businesses begin, end, or continue their operations and the associated job creation and destruction. The BDS is a valuable resource for information on the U.S. economy because of its long time series (1978-2019), its complete coverage (all private sector, non-farm U.S. businesses), and its tabulations for both individual establishments and the firms that own and control them. In this paper, we use the publicly available BDS data to describe the dynamics of the economy over the past 40 years. We highlight the increasing concentration of employment at old and large firms and describe net job creation trends in the manufacturing, retail, information, food/accommodations, and healthcare industry sectors. We show how the spatial distribution of employment has changed, first moving away from the largest cities and then back again. Finally, we show long-run trends for a group of industries we classify as high-tech and explore how the share of employment at small and young firms has changed for this part of the economy.
