Clusters of Entrepreneurship
October 2009
Working Paper Number:
CES-09-36
Employment growth is strongly predicted by smaller average establishment size, both across cities and across industries within cities, but there is little consensus on why this relationship exists. Traditional economic explanations emphasize factors that reduce entry costs or raise entrepreneurial returns, thereby increasing net returns and attracting entrepreneurs. A second class of theories hypothesizes that some places are endowed with a greater supply of entrepreneurship. Evidence on sales per worker does not support the higher returns for entrepreneurship rationale. Our evidence suggests that entrepreneurship is higher when fixed costs are lower and when there are more entrepreneurial people.

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.

Concentration Levels in the U.S. Advertising and Marketing Services Industry: Myth vs. Reality
August 2009
Working Paper Number:
CES-09-16
We analyze changes in concentration levels in the U.S. Advertising and Marketing Services industry using data from the U.S. Census Bureau's quinquennial Economic Census and the Service Annual Survey. Heretofore largely ignored, these data allow us to redress some of the measurement problems surrounding estimates found in the existing literature Firm level concentration as measured by the Herfindahl-Hirschman Index varies across the sectors comprising the industry, but all are within the range generally considered as indicative of a competitive industry. At the holding company level, the four largest organizations account for about a quarter of the industry's total revenue, a share lower by an order of magnitude than that frequently cited in the trade press.

Computer Network Use and Firms' Productivity Performance: The United States vs. Japan
September 2008
Working Paper Number:
CES-08-30
This paper examines the relationship between computer network use and firms' productivity performance, using micro-data of the United States and Japan. To our knowledge, this is the first comparative analysis using firm-level data for the manufacturing sector of both countries. We find that the links between IT and productivity differ between U.S. and Japanese manufacturing. Computer networks have positive and significant links with labor productivity in both countries. However, that link is roughly twice as large in the U.S. as in Japan. Differences in how businesses use computers have clear links with productivity for U.S. manufacturing, but not in Japan. For the United States, the coefficients of the intensity of network use are positive and increase with the number of processes. Coefficients of specific uses of those networks are positive and significant. None of these coefficients are significant for Japan. Our findings are robust to alternative econometric specifications. They also are robust to expanding our sample from single-unit manufacturing firms, which are comparable in the two data sets, to the entire manufacturing sector in each country, as well as to the wholesale and retail sector of Japan.

Transfer Pricing by U.S.-Based Multinational Firms
September 2008
Working Paper Number:
CES-08-29
This paper examines how prices set by multinational firms vary across arm's-length and related party customers. Comparing prices within firms, products, destination countries, modes of transport and month, we find that the prices U.S. exporters set for their arm's-length customers are substantially larger than the prices recorded for related-parties. This price wedge is smaller for commodities than for differentiated goods, is increasing in firm size and firm export share, and is greater for goods sent to countries with lower corporate tax rates and higher tariffs. We also find that changes in exchange rates have differential effects on arm's-length and related-party prices; an appreciation of the dollar reduces the difference between the prices.

Multi-Product Firms and Product Switching
August 2008
Working Paper Number:
CES-08-24
This paper examines the frequency, pervasiveness and determinants of product switching by U.S. manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and that product adding and dropping induce large changes in firm scope. The behavior we observe is consistent with a natural generalization of existing theories of industry dynamics that incorporates endogenous product selection within firms. Our findings suggest that product switching contributes to a reallocation of resources within firms towards their most efficient use.

Supersize It: The Growth of Retail Chains and the Rise of the "Big Box" Retail Format
August 2008
Working Paper Number:
CES-08-23R
This paper documents and explains the recent rise of "big-box" general merchandisers. Data from the Census of Retail Trade for 1977-2007 show that general-merchandise chains grew much faster than specialist retail chains, and that general merchandisers that added the most stores also made the biggest increases to their product offerings. We explain these facts with a stylized model in which a retailer's scale economies interact with consumer gains from one-stop shopping to generate a complementarity between a retailer's scale and scope.

The Going Public Decision and the Product Market
July 2008
Working Paper Number:
CES-08-20
At what point in a firm's life should it go public? How do a firm's ex ante product market characteristics relate to its going public decision? Further, what are the implications of a firm going public on its post-IPO operating and product market performance? In this paper, we answer the above questions by conducting the first large sample study of the going public decisions of U.S. firms in the literature. We use the Longitudinal Research Database (LRD) of the U.S. Census Bureau, which covers the entire universe of private and public U.S. manufacturing firms. Our findings can be summarized as follows. First, a private firm's product market characteristics (market share, competition, capital intensity, cash flow riskiness) significantly affect its likelihood of going public. Second, private firms facing less information asymmetry and those with projects that are cheaper for outsiders to evaluate are more likely to go public (consistent with Chemmanur and Fulghieri (1999)). Third, IPOs of firms occur at the peak of their productivity cycle (consistent with Clementi (2002)): the dynamics of total factor productivity (TFP) and sales growth exhibit an inverted U-shaped pattern. Finally, sales, capital expenditures, and other performance variables exhibit a consistently increasing pattern over the years before and after the IPO. The last two findings are consistent with the widely documented post-IPO operating underperformance of firms being due to the real investment effects of a firm going public, and inconsistent with underperformance being solely due to earnings management immediately prior to the IPO.

Analysis of Young Neighborhood Firms Serving Urban Minority Clients
May 2008
Working Paper Number:
CES-08-11
This study empirically investigates Michael Porter's hypothesis that urban minority neighborhoods offer attractive opportunities to household-oriented businesses, such as retail firms (1995). Our analysis compares the traits and performance of firms serving predominantly minority clients to those selling their products largely to clients who are nonminority whites. Controlling statistically for applicable firm and owner characteristics, our findings indicate that the minority neighborhood niche does not offer young firms an attractive set of opportunities. Relative to opportunities in the corresponding nonminority household niche and the broader regional marketplace, the neighborhood minority household market is associated with reduced business viability.

Private Equity and Employment
March 2008
Working Paper Number:
CES-08-07R
Private equity critics claim that leveraged buyouts bring huge job losses. To investigate this claim, we construct and analyze a new dataset that covers U.S. private equity transactions from 1980 to 2005. We track 3,200 target firms and their 150,000 establishments before and after acquisition, comparing outcomes to controls similar in terms of industry, size, age, and prior growth. Relative to controls, employment at target establishments declines 3 percent over two years post buyout and 6 percent over five years. The job losses are concentrated among public-to-private buyouts, and transactions involving firms in the service and retail sectors. But target firms also create more new jobs at new establishments, and they acquire and divest establishments more rapidly. When we consider these additional adjustment margins, net relative job losses at target firms are less than 1 percent of initial employment. In contrast, the sum of gross job creation and destruction at target firms exceeds that of controls by 13 percent of employment over two years. In short, private equity buyouts catalyze the creative destruction process in the labor market, with only a modest net impact on employment. The creative destruction response mainly involves a more rapid reallocation of jobs across establishments within target firms.
