Commonly used frictional models of the labor market imply that changes in frictions have large effects on steady state employment and unemployment. We use a model that features both frictions and an operative labor supply margin to examine the robustness of this feature to the inclusion of a...

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor with idiosyncratic shocks and frictions characterized by employment loss and...

The unemployment gender gap, defined as the difference between female and male unemployment rates, was positive until 1980. This gap virtually disappeared after 1980, except during recessions when men's unemployment rate always exceeds women's. We study the evolution of these gender differences...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality---through climate change---from using fossil energy. A central result of our paper is an analytical derivation of a simple formula for the marginal externality damage of emissions. This formula, which holds...

We consider a representative-agent equilibrium model where the consumer has quasi-geometric discounting and cannot commit to future actions. With restricted attention to a parametric class for preferences and technology logarithmic utility, Cobb-Douglas production, and full depreciation we solve...

Standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a small amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. We derive this result for a specific measure of...

Does capital-embodied technological change play an important role in shaping labour market inequalities? This Paper addresses the question in a model with vintage capital and search/matching frictions where costly capital investment leads to large heterogeneity in productivity among vacancies in...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

In this chapter we inspect economic mechanisms through which technological progress shapes the degree of inequality among workers in the labour market. A key focus is on the rise of US wage inequality over the past 30 years. However, we also pay attention to how Europe did not experience changes...
