Productivity Dispersion and Structural Change in Retail Trade
December 2023
Working Paper Number:
CES-23-60R
The retail sector has changed from a sector full of small firms to one dominated by large, national firms. We study how this transformation has impacted productivity levels, growth, and dispersion between 1987 and 2017. We describe this transformation using three overlapping phases: expansion (1980s and 1990s), consolidation (2000s), and stagnation (2010s). We document five findings that help us understand these phases. First, productivity growth was high during the consolidation phase but has fallen more recently. Second, entering establishments drove productivity growth during the expansion phase, but continuing establishments have increased in importance more recently. Third, national chains have more productive establishments than single-unit firms on average, but some single-unit establishments are highly productive. Fourth, productivity dispersion is significant and increasing over time. Finally, more productive firms pay higher wages and grow more quickly. Together, these results suggest that the increasing importance of large national retail firms has been an important driver of productivity and wage growth in the retail sector.

Developing a Residence Candidate File for Use With Employer-Employee Matched Data
January 2017
Working Paper Number:
CES-17-40
This paper describes the Longitudinal Employer-Household Dynamics (LEHD) program's ongoing efforts to use administrative records in a predictive model that describes residence locations for workers. This project was motivated by the discontinuation of a residence file produced elsewhere at the U.S. Census Bureau. The goal of the Residence Candidate File (RCF) process is to provide the LEHD Infrastructure Files with residence information that maintains currency with the changing state of administrative sources and represents uncertainty in location as a probability distribution. The discontinued file provided only a single residence per person/year, even when contributing administrative data may have contained multiple residences. This paper describes the motivation for the project, our methodology, the administrative data sources, the model estimation and validation results, and the file specifications. We find that the best prediction of the person-place model provides similar, but superior, accuracy compared with previous methods and performs well for workers in the LEHD jobs frame. We outline possibilities for further improvement in sources and modeling as well as recommendations on how to use the preference weights in downstream processing.

Bankruptcy Spillovers
January 2017
Working Paper Number:
CES-17-16
How do different bankruptcy approaches affect the local economy? Using U.S. Census microdata at the establishment level, we explore the spillover effects of reorganization and liquidation on geographically proximate firms. We exploit the random assignment of bankruptcy judges as a source of exogenous variation in the probability of liquidation. We find that within a five year period, employment declines substantially in the immediate neighborhood of the liquidated establishments, relative to reorganized establishments. Most of the decline is due to lower growth of existing establishments and, to a lesser extent, reduced entry into the area. The spillover effects are highly localized and concentrate in the non-tradable and service sectors, particularly when the bankrupt firm operates in the same sector. These results suggest that liquidation leads to a reduction in consumer traffic to the local area and to a decline in knowledge spillovers between firms. The evidence is inconsistent with the notion that liquidation leads to creative destruction, as the removal of bankrupt businesses does not lead to increased entry nor the revitalization of the area.

Evidence for the Effects of Mergers on Market Power and Efficiency
January 2016
Working Paper Number:
CES-16-43
Study of the impact of mergers and acquisitions (M&As) on productivity and market power has been complicated by the difficulty of separating these two effects. We use newly-developed techniques to separately estimate productivity and markups across a wide range of industries using confidential data from the U.S. Census Bureau. Employing a difference-in-differences framework, we find that M&As are associated with increases in average markups, but find little evidence for effects on plant-level productivity. We also examine whether M&As increase efficiency through reallocation of production to more efficient plants or through reductions in administrative operations, but again find little evidence for these channels, on average. The results are robust to a range of approaches to
address the endogeneity of firms' merger decisions.

Agglomerative Forces and Cluster Shapes
June 2012
Working Paper Number:
CES-12-09
We model spatial clusters of similar firms. Our model highlights how agglomerative forces lead to localized, individual connections among firms, while interaction costs generate a defined distance over which attraction forces operate. Overlapping firm interactions yield agglomeration clusters that are much larger than the underlying agglomerative forces themselves. Empirically, we demonstrate that our model's assumptions are present in the structure of technology and labor flows within Silicon Valley and its surrounding areas. Our model further identifies how the lengths over which agglomerative forces operate influence the shapes and sizes of industrial clusters; we confirm these predictions using variations across both technology clusters and industry agglomeration.

Acquiring Labor
October 2011
Working Paper Number:
CES-11-32
We present evidence that some firms pursue M&A activity with the objective of obtaining a larger workforce. Firms most likely to be acquired for their large labor force, firms with the largest ex ante employment, are associated with more positive post-merger employment outcomes. Moreover, we find this relation is strongest when acquiring labor outside of an M&A is likely to be most difficult, due to tight labor conditions, or most valuable, in high human capital industries. We further find that high employment target firms are associated with relatively greater post-merger wage increases and lower post-merger employee turnover. We find no evidence that the positive relation between target ex ante employment and ex post employment change is driven by target asset size, market capitalization, industry, profitability or acquirer characteristics. Our findings do not exclude the possibility that a different subset of M&A activity may be motivated to penalize managers who have tolerated over-employment. Indeed, we find evidence consistent with this disciplinary motivation when considering acquisitions of targets in declining industries.

Competition and Productivity: Evidence from the Post WWII U.S. Cement Industry
September 2010
Working Paper Number:
CES-10-29
In the mid 1980s, the U.S. cement industry faced a large increase in foreign competition. Foreign cement producers began offering cement at very large discounts on U.S. prices. We show that productivity (measured by TFP) in the industry was falling during the 1960s and 1970s, but that following the increase in competition, productivity has reversed course and is growing strongly. When foreign competition was weak, productivity fell. When it was strong, productivity grew robustly. We explore the reasons for the large productivity increase. We argue that a large share of the productivity gains resulted from significant changes in management practices at plants.

Discretionary Disclosure in Financial Reporting: An Examination Comparing Internal Firm Data to Externally Reported Segment Data
September 2009
Working Paper Number:
CES-09-28
We use confidential, U.S. Census Bureau, plant-level data to investigate aggregation in external reporting. We compare firms' plant-level data to their published segment reports, conducting our tests by grouping a firm's plants that share the same four-digit SIC code into a 'pseudo-segment.' We then determine whether that pseudo-segment is disclosed as an external segment, or whether it is subsumed into a different business unit for external reporting purposes. We find pseudo-segments are more likely to be aggregated within a line-of-business segment when the agency and proprietary costs of separately reporting the pseudo-segment are higher and when firm and pseudo-segment characteristics allow for more discretion in the application of segment reporting rules. For firms reporting multiple external segments, aggregation of pseudo-segments is driven by both agency and proprietary costs. However, for firms reporting a single external segment, we find no evidence of an agency cost motive for aggregation.

The Efficiency of Internal Capital Markets: Evidence from the Annual Capital Expenditure Survey
April 2008
Working Paper Number:
CES-08-08
We empirically examine whether greater firm diversity results in the inefficient allocation of capital. Using both COMPUSTAT and the Annual Capital Expenditure Survey (ACES) we find firm diversity to be negatively related to the efficiency of investment. However once we distinguish between capital expenditure for structures and equipment, we find that while firms do inefficiently allocate capital for equipment, they efficiently allocate capital for structures. These results suggest that when the decision will have long-lasting repercussions, headquarters will, more often than not, make the correct choice.

Democratizing Entry: Banking Deregulations, Financing Constraints, and Entrepreneurship
December 2007
Working Paper Number:
CES-07-33
We study how US branch-banking deregulations affected the entry and exit of firms in the non-financial sector using establishment-level data from the US Census Bureau's Longitudinal Business Database. The comprehensive micro-data allow us to study how the entry rate, the distribution of entry sizes, and survival rates for firms responded to changes in banking competition. We also distinguish the relative effect of the policy reforms on the entry of startups versus facility expansions by existing firms. We find that the deregulations reduced financing constraints, particularly among small startups, and improved ex ante allocative efficiency across the entire firm-size distribution. However, the US deregulations also led to a dramatic increase in 'churning' at the lower end of the size distribution, where new startups fail within the first three years following entry. This churning emphasizes a new mechanism through which financial sector reforms impact product markets. It is not exclusively better ex ante allocation of capital to qualified projects that causes creative destruction; rather banking deregulations can also 'democratize' entry by allowing many more startups to be founded. The vast majority of these new entrants fail along the way, but a few survive ex post to displace incumbents.
