I build a dynamic stochastic general equilibrium model with search and matching frictions in the labor market and analyze the optimal monetary policy response to an outward shift in the Beveridge curve. The results cover several cases depending on the reason for the shift. If the shift is due to...

We introduce skill decay during unemployment into Blanchard and Gali's (2008) New-Keynesian model with hiring frictions and real-wage rigidity. Plausible values of quarterly skill decay and real-wage rigidity turn the long-run marginal cost-unemployment relationship positive in a "European"...

We present a model in which temporary shocks can permanently scar the economy's productive capacity. Unemployed workers lose skill and are expensive to retrain, generating multiple steady state unemployment rates. Large temporary shocks push the economy into a liquidity trap, generating...

We investigate the relationship between unemployment and growth in China. We find considerable differences in the nature of this relationship across Chinese regions. We argue that this may reflect the different progress in transition across regions, in line with the Aghion-Blanchard model of...

Firms and consumers both hold significant amounts of money, and the firm share changes over time and is negatively correlated with inflation. While existing studies of monetary policy and unemployment only consider consumer money, we build a quantitative framework of money allocation between...

We analyze monetary policy in a model where temporary shocks can permanently scar the economy's productive capacity. Unemployed workers' skill losses generate multiple steady-state unemployment rates. When monetary policy is constrained by the zero bound, large shocks reduce hiring to a point...

When workers are exposed to human capital depreciation during periods of unemployment, hiring affects the unemployment pool's composition in terms of skills, and hence the economy's production potential. Introducing human capital depreciation during unemployment into an otherwise standard New...

We build a New Keynesian business-cycle model with rich household heterogeneity. In the model, systematic monetary stabilization policy affects the distribution of income, income risks, and the demand for funds and supply of assets: the demand, because matching frictions render idiosyncratic...

This paper provides evidence for a positive effect of total factor productivity growth on unemployment in cross-country regressions for OECD countries. The paper explains this empirical result with an exogenous growth model with unemployment due to unions and a CES production function with an...

We introduce skill decay during unemployment into Blanchard and Gali's (2008) New-Keynesian model with hiring frictions and real-wage rigidity. Plausible values of quarterly skill decay and real-wage rigidity turn the long-run marginal cost-unemployment relationship positive in a "European"...
