The introduction of firm size into labor search models raises the question how wages are setwhen average and marginal product differ. We develop and analyze an alternative to theexisting bargaining framework: Firms compete for labor by publicly posting long- termcontracts. In such a competitive...

In contrast to the very large literature on skill-biased technical change among workers, thereis hardly any work on the importance of skills for the entrepreneurs who employ thoseworkers, and in particular on their evolution over time. This paper proposes a simple theory ofskill-biased change in...

This paper analyzes the effect of firing costs on aggregate productivity growth. For thispurpose, a model of endogenous growth through selection and imitation is developed. It isconsistent with recent evidence on firm dynamics and on the importance of reallocation forproductivity growth...

This paper investigates the relation between changes in self-employment and changes in unemployment at the regional level in Spain in the period 1979-2001. We estimate a vec-tor autoregression model as proposed by Audretsch, Carree, van Stel and Thurik (2005) using a data base for Spanish...

We provide the impact on asset prices of search-and-bargaining frictions in over-the-counter markets. Under natural conditions, prices are lower and illiquidity discounts higher when counterparties are harder to find, when sellers have less bargaining power, when the fraction of qualified owners...

Recently, Diebold and Li (2003) obtained good forecasting results foryield curves in a reparametrized Nelson-Siegel framework. We analyze similarmodeling approaches for price curves of variance swaps that serve nowadaysas hedging instruments for options on realized variance. We consider the...

We consider how the amount of the technology transferred and the characteristics of the partneraffect licensing. We find that a partial technology transfer can be the joint-profit minimizingtransfer, though under weakly concave demand, a complete transfer always increases joint profitif there...

This study uses an agent-based test bed (“AMES”)to investigate separation and volatility of locational marginalprices (LMPs) in an ISO-managed restructured wholesale powermarket operating over an AC transmission grid. Particular attentionis focused on the dynamic and cross-sectional response...

In April 2003 the U.S. Federal Energy Regulatory Commission proposed a complicated marketdesign – the Wholesale Power Market Platform (WPMP) – for common adoption byall U.S. wholesale power markets. Versions of the WPMP have been implemented in NewEngland, New York, the mid-Atlantic states,...

Market concentration ratios are popular statistics for characterizing the extent of marketdominance in an imperfectly competitive market, but these ratios may not agree whencomparing two markets. Neither do they necessarily agree with the Herfindahl-Hirschman orentropy indices. This letter...
