In this paper we show that panel estimates of tenure specific sensitivity to the business cycle of wages is subject to serious pitfalls. Three canonical variates used in the literature – the minimum unemployment rate during a worker's time at the firm (min u), the unemployment rate at the...

Following insights by Bewley (1999a), this paper analyses a model with downward rigidities in which firms cannot pay discriminate based on a year of entry to a firm, and develops an equilibrium model of wages and unemployment. We solve for the dynamics of wages and unemployment under conditions...

Recent dynamic contracting models of downward real wage rigidity with "equal treatment" – newly hired workers cannot price themselves into jobs by undercutting incumbents – imply that real wages are relatively rigid in "bad" times but upwardly flexible during "good" times. We use an...

In models recently published by several influential macroeconomic theorists, rigidity in the real wages that firms pay newly hired workers plays a crucial role in generating realistically large cyclical fluctuations in unemployment. There is remarkably little evidence, however, on whether...

It is well known that, unless worker-firm match quality is controlled for, returns to firm tenure (RTT) estimated directly via reduced form wage (Mincer) equations will be biased. In this paper we argue that even if match quality is properly controlled for there is a further pervasive source of...

This paper presents a new model of firms' decisions on training in a context of potential worker mobility. Such worker mobility can be influenced by employers coordination, namely through the operation of no-poach agreements and employers' associations (EAs). We then present supporting evidence...
