The limited nature of data on employment referrals in large business and household surveys has so far impeded our efforts to understand the relationships among employment referrals, match quality, wage trajectories, and turnover. Using a new firm-level data set that includes explicit information...

This paper suggests that in the US context, workers tend to invest in general human capital especially since they face little employment protection and low unemployment benefits, while the European model (generous benefits and higher duration of jobs) favors specific human capital investments....

We consider a model of on-the-job search where firms offer long-term wage contracts to workers of different ability. Firms do not observe worker ability upon hiring but learn it gradually over time. With sufficiently strong information frictions, low-wage firms offer separating contracts and...

We estimate Frisch elasticity in a labor market with high job turnover. In a context where only around 18% of the employed labor force has formal and stable jobs, we perform a fixed effects estimation as proposed by MaCurdy (1981) with a Heckman correction for selection into unemployment. We...

This paper studies the quantitative properties of a multiple-worker firm matching model with on-the-job search where heterogeneous firms operate decreasing-returns-to-scale production technology. The authors focus on the model's ability to replicate the business cycle features of job flows,...

We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

Portuguese firms engage in intense reallocation, most employers simultaneously hire and separate from workers, resulting in a large heterogeneity of flows and excess turnover. Large and older firms have lower flows, but high excess turnover rates. In small firms, hires and separations move...

Worker flows and job flows behave differently over the business cycle. We investigate the sources of the differences by studying quantitative properties of a multiple-worker version of the search/matching model that features endogenous job separation and intra-firm wage bargaining. Our...

This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...

This paper explores, both theoretically and empirically, how firing costs affect worker productivity and turnover. We develop a model in which workers are essential to knowledge transfer between firms and worker effort is firm-specific in the sense that a worker can be fired before reaping the...
