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...

A key question in labor market research is how the unemployment insurance system affects unemployment rates and labor market dynamics. We revisit this old question studying the German Hartz reforms. On average, lower separation rates explain 76% of declining unemployment after the reform, a fact...

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...

This article is an idiosyncratic survey of the insider-outsider theory, describing the vision underlying the theory, and evaluating salient contributions to the literature in the light of this vision. We also indicate what appear to have been dead-ends and red herrings in past research. The...

The paper examines the relative effectiveness of two policy proposals in reducing unemployment and working poverty: unemployment vouchers and low-wage subsidies. The unemployment vouchers are targeted exclusively at the unemployed (especially the longterm unemployed) and are provided only for a...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...
