We adapt the wage contracting structure in Chari (1983) to a dynamic, balanced-growth setting with re-contracting à la Calvo (1983). The resulting wage-rigidity framework delivers a model very similar to that in Jaimovich and Rebelo (2009), with their habit parameter replaced by our probability...

This paper surveys recent developments in the literature on efficiency wage theories of unemployment. Efficiency wage models have in common the property that in equilibrium firms may find it profitable to pay wages in excess of market clearing. High wages can help reduce turnover, elicit worker...

This paper considers two sets of theories attempting to explain wage rigidities and unemployment: implicit contract theory and the efficiency wage theory. The basic thesis of the paper is that the former set of theories do not provide a convincing explanation of the kind of wage rigidity which...

This paper analyzes equilibrium in labor markets with costly search. Even in steady state equilibrium, identical labor may receive different wages; this may be the case even when the only source of imperfect information is the inequality of wages which the market is perpetuating. When there are...

Fluctuations in the equilibrium rate of unemployment can only be understood within a theory of the natural or equilibrium rate. It is not enough to say that unemployment is the difference between supply and demand in the labor market, though of course it always will be. In equilibrium, no...

We study the time-series properties of firm effects in the two-way fixed effects models popularized by Abowd, Kramarz, and Margolis (1999) (AKM) using two approaches. The first--the rolling AKM approach (R-AKM)--estimates AKM models separately for successive two-year intervals. The second--the...

Using administrative payroll data from the largest U.S. payroll processing company, we document a series of new facts about nominal wage adjustments in the United States. The data allow us to define a worker's per-period base contract wage separately from other forms of compensation such as...

This paper explores the relationship between the duration of a vacancy and the starting wage of a new job, using unusually informative data comprising detailed information on vacancies, the establishments posting the vacancies and the workers eventually filling the vacancies. We find that...

There has been a remarkable increase in wage inequality in the US, UK and many other countries over the past three decades. A significant part of this appears to be within observable groups (such as age-gender-skill cells). A generally untested implication of many theories rationalizing the...
