One of the most controversial aspects of immigration policy is the impact of foreigners on labour market outcomes of natives. Simple labour supply analysis demonstrates that these effects depend upon whether immigrants and natives act as substitutes or complements. In the first part of the study...

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...

The paper studies the effect of potential unemployment benefit duration on the length of unemployment spells in Austria. It takes advantage of a quasi-experimental situation, where potential benefit duration was extended in 1988 for elderly workers living in specific regions of the country. The...

This paper studies the impact of a selective extension of unemployment benefit duration on the incidence of unemployment in Austria. As the new law applies only to elderly workers in certain regions of the country after June 1988, a quasi-experimental situation is created. Unemployment entry is...

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...
