We analyze how frictions in the labour market influence the accumulation of general human capital. We find that investments in human capital benefits future employers, and that this positive externality leads to under-investments in human capital, and possibly top multiple, Pareto rankable...

We construct a model integrating the efficiency wage model of Shapiro-Stiglitz (1984) with the matching-bargaining models of Diamond, Mortensen and Pissarides (DMP). Firms and workers form pairwise matches, workers may shirk on the job, and the wage is set in an asymmetric Nash bargain over the...

We study the effects of mobility costs in a model of wage bargaining between workers and firms, where there is instantaneous matching, free firm entry, heterogeneous labour, and workers' individual productivities are discovered by firms only after being hired. We derive the employment level and...

In many regulated industries labour uions are strong and there is clear empirical evidence of labour rent-sharing. We study optimal regulation in a model in which wages are determined endogenously by wage bargaining at the firm level. Compared to the case in which wages do not depend on the...

We introduce strategic wage bargaining in a search equilibrium model. We find that wages respond more an employment and output less to aggreagte shoks than when wages are determined by conventional Nash bargaining. Expectations about the stocks increase the volatility of wages even more.
