We study the properties of optimal monetary policy in an environment of nominal wage rigidity and unemployment. We show that nominal wage rigidity increases the sacrifice ratio, and therefore reduces the effectiveness of sacrificing employment in order to stabilize inflation. It follows that in...

This paper proposes a hidden state Markov model (HMM) that incorporates workers' unobserved labor market attachment into the analysis of labor market dynamics. Unlike previous literature, which typically assumes that a worker's observed labor force status follows a first-order Markov process,...

This paper disciplines a model with search over match quality using microeconomic evidence on worker mobility patterns and wage dynamics. In addition to capturing these individual data, the model provides an explanation for aggregate labor market patterns. Poor match quality among first jobs...

In this paper, we examine how skill loss can contribute to aggregate labor market fluctuations in the Diamond-Mortensen-Pissarides model. We develop a computationally tractable stochastic version of that model wherein workers accumulate skills on the job and face a risk of skill loss after job...
