This paper presents a model in which mismatch employment arises in a constrained efficient equilibrium. In the decentralized economy, however, mismatch gives rise to a congestion externality whereby heterogeneous job seekers fail to internalize how their individual actions affect the labor...

We study the role of labor market mismatch in the adjustment to a trade liberalization that results in the offshoring of high-tech production. Our model features two-sided heterogeneity in the labor market: high- and low-skilled workers are matched in a frictional labor market with high- and...

This paper characterizes efficient labor-market allocations in a labor selection model. The model's crucial aspect is cross-sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross-sectional dispersion calibrated to microeconomic...

This paper characterizes long-run and short-run optimal fiscal policy in the labor selection framework. In a calibrated non-Ramsey decentralized equilibrium, labor market volatility is inefficient. Keeping fixed the structural parameters, the Ramsey government achieves efficient labor market...
