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...

Previous papers tested the validity of the Family Investment Hypothesis (FIH) among immigrants by comparing the labor market outcomes of immigrant couples and native or mixed couples. Here we propose an alternative test for the FIH which is based on a comparison between married and single...

The purpose of this study is to investigate the relationship between a firm's R&D expenditures considered as an investment in knowledge, and its productivity, looking at sectoral peculiarities which may emerge; to this end, we use a large unique longitudinal database consisting of 1,809 US and...

The decisions of firms on investment and hiring play a crucial role in business cycle fluctuations. This paper explores their dynamic behavior in the presence of frictions. It does so within a unified framework, stressing their mutual dependence and placing the emphasis on their joint,...

This paper provides some empirical evidence and a theory of the relationship between residual wage inequality and the increasing dispersion of capital/labor ratios across firms. I document the increasing variance of capital/labor ratios across firms in the US labor market. I also show that the...

What role does labor play in firms? market value? We explore this question using a production-based asset pricing model with frictions in the adjustment of both capital and labor. We posit that hiring of labor is akin to investment in capital and that the two interact, with the interaction being...

This study examines optimal taxation in a unionized economy in which households save capital. The main findings are as follows. Judd?s (1985) and Chamley?s (1986) classical results of zero taxation on capital income holds. This is true independently of workers? savings behaviour or the...

We consider an economy in which firms need to invest in capital before they can advertise a job, while applicants may have to compete for jobs. Our aim is to investigate how this competition affects the investment decisions of firms. Our first result shows that the economy always generates the...

We study the implications of product market competition and investment for price setting, wage bargaining and thereby for equilibrium unemployment in an economy with product and labour market imperfections. We show that intensified product market competition will reduce equilibrium unemployment,...

We present evidence that an increase in investment as a share of GDP predicts a higher growth rate of output per worker, not only temporarily, but also in the steady state. These results are found using pooled annual data for a large panel of countries, using pooled data for non-overlapping...
