In this paper we construct a simple model of the effects of immigration on the labour market outcomes of natives. In this model, skilled and unskilled labour are substitutes, immigrants are complementary to the former, and wages are determined by bargaining. We are able to prove that,...

This paper presents a case study on reforming a very dysfunctional labour market with a deep insider-outsider divide, namely the Spanish case. We show how a dual market, with permanent and temporary employees makes real reform much harder, and leads to purely marginal changes that do not alter...

This Paper analyses the welfare effects of price restrictions on private contracting in a world where agents have a limited cognitive ability. People compute the costs and benefits of entering a transaction with an error. The government knows the distribution of true costs and benefits as well...

This Paper considers a matching model of heterogeneous workers and jobs, which includes on-the-job search. High-educated workers transitorily accept unskilled jobs and continue to search for skilled jobs. We study the implications of this model for the unemployment rates of high and low-educated...

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...

We study active labor market policies (ALMP) in a matching model. ALMPs are modelled as a subsidy to job search. Workers differ in their productivity, and search takes place along an extensive margin. An additional job seeker affects the quality of unemployed workers. As a result, the Hosios...

We develop a simple model to study how relative wage rigidity affects equilibrium taxation. It is argued that relative wage rigidity, by compressing incomes within the middle class, leads to a lower degree of redistributive conflict within the politically important core of society, even though...

This paper studies a model of human capital accumulation with real wage rigidity. It is shown that the arbitrage condition between hiring a skilled versus an unskilled worker may be stated as a positive relationship between their relative unemployment rates. It may be the case that this locus is...
