This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

Do firms reduce employment when their insiders (established, incumbent employees) claim higher wages? The conventional answer in the theoretical literature is that insider power has no influence on employment, provided that the newly hired employees (entrants) receive their reservation wages....

Suppose insiders use their market power to push up their wages, while entrants receive their reservation wages. How will employment be affected? In addressing this question, we focus on the role of on-the-job training. We show that an insider wage hike reduces recession-time employment but, in...

This paper studies optimal UI policy from the perspective of worker assignment to heterogenous jobs in an environment of random matching. Workers react to UI policy through job acceptance decisions; firms react to UI policy through wage posting. There is endogenous assortative matching as a...

The introduction of firm size into labor search models raises the question how wages are set when average and marginal product differ. We develop and analyze an alternative to the existing bargaining framework: Firms compete for labor by publicly posting long- term contracts. In such a...

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...

This paper provides a novel justification for a declining time profile of unemployment benefits that does not rely on moral hazard or consumption-smoothing considerations. We consider a simple search environment with homogeneous workers and low- and high-productivity firms. By introducing a...

This paper provides a critique of the "unemployment invariance hypothesis", according to which the behavior of the labor market ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity, and the labor force. Using Solow growth and endogenous growth...

We explore the implications of replacing current unemployment benefit (UB) systems by unemployment accounts (UA). Under the UA system, employed people would be required to make ongoing contributions to their unemployment accounts, and the balances in these accounts would then be available to...

The paper explores the employment implications of allowing people the opportunity of using a portion of their incapacity benefits to provide employment vouchers for employers that hire them. The analysis indicates that introducing this policy could increase employment, raise the incomes of...
