We extend the standard textbook search and matching model by introducing deep habits in consumption. The cyclical fluctuations of vacancies and unemployment in our model can replicate those observed in the US data, with labour market tightness being 20 times more volatile than consumption....

In this lecture I first give an explanation for invidious preferences based on the (evolutionary) competition for resources. Then I show that these preferences have wide ranging and empirically relevant effects on labor markets, such as: workplace skill segregation, gradual promotions, wage...

Standard macroeconomic models underpredict the volatility of unemployment fluctuations. A common solution is to assume wages are rigid. We explore whether this explanation is consistent with the data. We show that the wage of newly hired workers, unlike the aggregate wage, is volatile and...

This paper examines the ex post flexibility of U.S. labor contracts during the 1970-95 period by investigating whether unanticipated changes in inflation increase the likelihood of a contract being renegotiated prior to its expiration. We find strong empirical support for this hypothesis....

ln as much as the U.S. economy has been slow in recovery from deep recession with unemployment hovering around 9 per cent due to the short-sighted non-Keynesian approach of the U.S. administration by imposition of highly expensive visa fees with restrictions on employment of foreign skilled...

Occupational licensing and non-competition agreements are two important types of labour market regulation in the United States, both covering around one fifth of all workers. While some regulation is needed to protect safety and ensure quality of services, it also creates entry barriers and...

Many workers believe that personal contacts are crucial for obtaining jobs in high-wage sectors. On the other hand, firms in high-wage sectors report using employee referrals because they help provide screening and monitoring of new employees. This paper develops a matching model that can...

We use a novel approach to studying the heterogeneity in the job finding rates of the nonemployed by classifying the nonemployed by labor force status (LFS) histories, instead of using only one-month LFS. Job finding rates differ substantially across LFS histories: they are 25-30% among those...

In this paper, we present a matching model with adverse selection that explains why flows into and out of unemployment are much lower in Europe compared to North America, while employment-to-employment flows are similar in the two continents. In the model, firms use discretion in terms of whom...
