The UK and the US have experienced both rising skill premia and rising employment of skilled workers since the 1980s. These trends are typically interpreted as concurrent shifts of relative skill supplies and demands, and the demand shifts are attributed to skill-biased technological change or...

This paper develops and tests a new model of asymmetric information in the labour market involving employer learning. In the model, I provide theoretical conditions for the identification – based on the experience and tenure profiles of estimated returns to ability and education – of...

Starting a firm with expansive potential is an option for educated and high-skilled workers. This option serves as an insurance against unemployment caused by labor market frictions and hence increases the incentives for education. We show within a matching model that reducing the start-up costs...

This paper considers a matching model with heterogenous jobs (unskilled and skilled) and workers (low and high-educated) which allows for on-the-job search by mismatched workers. The latter are high-educated workers who transitorily accept unskilled jobs and continue to search for skilled jobs....

This paper introduces aging of workers into the neoclassical theory of labor demand. Among other things, it is shown that under reasonable hypotheses employment, even of younger workers, increases in the span of working life. Using the standard model without aging, the analysis of such issues...

We examine theoretically demand in a two-good economy where the demand of one good is influenced by either a spillover effect in the form of an externality from other consumers' choices and or a conformity effect representing a need for making similar choices as others. A positive spillover...

We examine the timing of firms' operations in a formal model of labor demand. Merging a variety of data sets from Portugal from 1995-2004, we describe temporal patterns of firms' demand for labor and estimate production-functions and relative labor-demand equations. The results demonstrate the...
