since the expected wage is increasing in the expected number of offers received since the job started. The business-cycle volatility of wages is higher for new hires and for job-to-job switchers than for job stayers since workers can sample from a larger pool of job offers in a boom than in a...

The rapidly growing literature studying the returns to firm- and government-sponsored training has made a striking observation. Returns to firm-sponsored training are positive and large while returns to government-sponsored training are low or even negative, especially in the short run. This has...

The Dynamic Effects of Aggregate Demand and Supply Disturbances in Models with Heterogeneous Inputs

We document an almost perfect negative correlation between the returns to experience and the average experience per worker in the labor market. We provide a model that rationalizes this finding. We consider workers as providing two distinct productive services - physical effort, or ``labor,''...

This finding is important for several active lines of research in macro/labor. For example, in the literature on the quantitative analysis of labor search models, it is the behavior of wages that distinguishes different calibration strategies with radically different implications. Current...

We show that the key identifying assumptions underlying the existing approaches to identifying technology shocks in the data are violated in models with heterogeneous capital and labor. We propose a new method to identifying technology shocks in the data in presence of factor heterogeneity and...

Two salient changes in the US wage structure have occurred over the past three decades: first, a sharp increase in the wage premium to schooling despite a continual increase in the supply of schooling, and second, a rise and then fall of the wage premium to work experience. Capital-skill...
