This paper presents a modified and improved methodology for the decomposition of wage differentials between two groups of workers into an endowment component and a discrimination component. The standard decomposition technique does not take into account different probabilities of entering the...

This Paper studies the inter-temporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm's rate of productivity growth approaches the rate of wage growth and eventually the firm reaches...

The need for locational competition among labour markets arises when labour is immobile. At the same time market clearing under such conditions can lead to wage and income variability. In such cases demand for insurance against regional shocks arises, which can be provided by nationwide...

Existing theories of unions emphasize their impact on wage levels relative to the opportunity cost of leisure. This paper explores the possibility that monopoly unions provide income insurance against idiosyncratic wage variability. An optimal union contract is characterized by real wage and...

This paper offers a model of the interaction between composition of jobs and labour market regulation. Ex-post rent-sharing due to search frictions implies that ‘good’ jobs which have higher creation costs must pay higher wages. This wage differential distorts the composition of jobs, and in...

Recent studies have shown that there are significant earnings differentials between immigrants and natives in Switzerland. The goal of this paper is to determine whether these differences can be attributed to diverging socio-economic endowments or to discrimination. We use the well-known...
