To what extent do different firms follow different wage policies? How do such policies affect worker mobility between firms, and what are the effects of different wage bargaining regimes? The empirical branch of personnel economics has long been hampered by a lack of representative data sets....

This paper uses data on very small UK geographies to investigate the effective size of local labor markets. Our approach treats geographic space as continuous, as opposed to a collection of non-overlapping administrative units, thus avoiding problems of mismeasurement of local labor markets...

Job reallocation is considered to be a key characteristic of well-functioning labor markets, as more productive firms grow and less productive ones contract or close. However, despite its potential benefits for the economy, there are significant costs that are borne by displaced workers. We...

The assumption of constant returns in the matching function, embodied in most bilateral search models, is crucial to ensure the uniqueness of the unemployment rate along a steady state growth path. This paper explores whether this is an acceptable assumption by estimating individual...

A new methodology is described which tests between various equilibrium theories of unemployment using matching data. The Paper shows how to correct econometrically for temporal aggregation effects, where the econometrician’s aim is to identify a matching process using data which is recorded...

We survey the microfoundations, empirical evidence and estimation issues underlying the aggregate matching function. Several microeconomic matching mechanisms have been suggested in the literature with some successes but none is generally accepted as superior to all others. Instead, an aggregate...

Theory predicts that mandated employment protections may reduce productivity by distorting production choices. Firms facing (non-Coasean) worker dismissal costs will curtail hiring below efficient levels and retain unproductive workers, both of which should affect productivity. These theoretical...

Average schooling in US states is highly correlated with state wage levels, even after controlling for the direct effect of schooling on individual wages. We use an instrumental variables strategy to determine whether this relationship is driven by social returns to education. The instrumentals...

In the standard model of human capital with perfect labor markets general training. When labor market frictions compress the structure of wages in the general skills of their employees. The reason is that the distortion in the wage structure" turn technologically' general skills into specific'...

This paper offers a model where firms decide what types of jobs to create and then search for suitable workers. When there are few skilled workers and the productivity gap between the skilled and the unskilled is small, firms create a single type of job and recruit all workers. An increase in...
