Information Technology, Capabilities and Asset Ownership: Evidence from Taxicab Fleets
Evan Rawley, Tim Simcoe
November 01, 2009
We examine how information technology (IT) influences asset ownership through its
impact on firms’ and agents’ capabilities. In particular, we propose that when IT is a substitute for
agents’ industry-specific human capital, IT adoption leads to increased vertical integration. We
test this prediction using micro data on vehicle ownership patterns from the Economic Census
during a period when computerized dispatching systems were first adopted by taxicab firms. The
empirical tests exploit exogenous variation in local market conditions, to identify the impact of
dispatching technology on firm asset ownership. The results show that firms increase the
proportion of taxicabs owned by 12% when they adopt new computerized dispatching systems.
The findings suggest that firms increasingly vertically integrate when they acquire resources that
substitute for their agents’ capabilities.

Plant-Level Responses to Antidumping Duties: Evidence from U.S. Manufacturers
Justin Pierce
October 01, 2009
This paper describes the effects of a temporary increase in tariffs on the performance and
behavior of U.S. manufacturers. Using antidumping duties as an example of temporary
protection, I compare the responses of protected manufacturers to those predicted by models of
trade with heterogeneous firms. I find that apparent increases in revenue productivity associated
with antidumping duties are primarily due to increases in prices and mark-ups, as physical
productivity falls among protected plants. Moreover, antidumping duties slow the reallocation of
resources from less productive to more productive uses by reducing product-switching behavior
among protected plants.

The Effect of Wage Insurance on Labor Supply: A Test for Income Effects
Henry Hyatt
October 01, 2009
Studies of moral hazard in wage insurance programs such as Unemployment Insurance
(UI) or Workers Compensation (WC) have demonstrated that higher benefits discourage work,
emphasizing the price distortion inherent in benefit provision. Utilizing administrative data
linking WC claim records to wage records from a UI payroll tax database, I find that the effect of
WC benefits on the duration of benefit receipt cannot fully account for the effect of these
benefits on post-injury unemployment. This indicates that a significant fraction of the effect of
WC benefits on employment is due to an income effect rather than a price distortion.

Clusters of Entrepreneurship
Edward Glaeser, William Kerr, Giacomo Ponzetto
October 01, 2009
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.

The Center for Economic Studies 1982-2007: A Brief History
B.K. Atrostic
October 01, 2009
More than half a century ago, visionaries representing both the Census Bureau and the external research community laid the foundation for the Center for Economic Studies (CES) and the Research Data Center (RDC) system. They saw a clear need for a system meeting the inextricably related requirements of providing more and better information from existing Census Bureau data collections while preserving respondent confidentiality and privacy. CES opened in 1982 to house new longitudinal business databases, develop them further, and make them available to qualified researchers. CES and the RDC system evolved to meet the designers’ requirements. Research at CES and the RDCs meets the commitments of the Census Bureau (and, recently, of other agencies) to preserving confidentiality while contributing paradigm-shifting fundamental research in a range of disciplines and up-to-the-minute critical tools for decision-makers.
