In this paper we use a very large matched database on firms and employees to analyze the use of temporary agencies by low earners, and to estimate the impact of temp employment on subsequent employment outcomes for these workers. Our results show that, while temp workers have lower earnings than others while working at these agencies, their subsequent earnings are often higher - but only if they manage to gain stable work with other employers. Furthermore, the positive effects seem mostly to occur because those working for temp agencies subsequently gain access to higher-wage firms than do comparable low earners who do not work for temps. The positive effects we find seem to persist for up to six years beyond the period during which the temp employment occurred.

We estimate the effects of technology investments on the demand for skilled workers using longitudinally integrated employer-employee data from the U.S. Census Bureau's Longitudinal Employer-Household Dynamics Program infrastructure files spanning two Economic Censuses (1992 and 1997). We estimate the distribution of human capital and its observable and unobservable components within each business for each year from 1992 to 1997. We measure technology using variables from the Annual Survey of Manufactures and the Business Expenditures Survey (services, wholesale and retail trade), both administered during the 1992 Economic Census. Static and partial adjustment models are fit. There is a strong positive empirical relationship between advanced technology and skill in a cross-sectional analys...

Innovation in the U.S. economy is about employing and rewarding highly talented workers to produce new products. Using unique longitudinal matched employer-employee data, this paper makes a key connection between talent and firms in markets with risky product innovations. We show that software firms that operate in product markets with highly skewed returns to innovation, or high variance payoffs, are more likely to attract and pay for star workers. Thus, firms in high variance product markets pay more up-front—in starting salaries—to attract and motivate star employees, because if these star workers produce home-run innovations, the firm’s winnings will be huge. However, we also find these same firms pay highly for loyalty: star workers that stay with a firm have much higher earnings...

This paper exploits a new matched universal and longitudinal employer-employee database at the US Census Bureau to empirically investigate the link between firms' choice of worker mix and the implied relationships between productivity and wages. We particularly focus on the decision making process of new firms and examine the role of both learning and selection. Our key empirical results are: (i) We find substantial and persistent differences in earnings per worker, output per worker, and worker mix across businesses within narrowly defined industries, which remain even after controlling for other observable characteristics. (ii) We find that new businesses exhibit even greater heterogeneity in earnings and productivity than do mature businesses, but that they adjust to the mature busi...
