Standard models of equilibrium unemployment assume exogenous labour market institutions and flexible wage determination. This paper models wage rigidity and collective bargaining endogenously, when workers differ by observable skill and may adopt either individualised or collective wage...

This paper is a progress report on understanding the relationship betweenprices and allocations of risks on financial markets versus macroeconomicchoices and allocations. In this paper, I investigate the scope of a modelwith exogenous habit formation – or “catching up with the Joneses”,...

The paper provides evidence concerning incidence and sources of nominal wage rigidity in servicesand manufacturing, using a new and large employer survey on wage and price setting behaviour forGermany. We observe that wage freezes are more frequent in services than in manufacturing, whereaswage...

Many European countries restrict immigration from new EU member countries. The rationaleis to avoid adverse wage and employment eects. We quantify these eects forGermany. Following Borjas (2003), we estimate a structural model of labor demand,based on elasticities of substitution between workers...

This paper presents new evidence on the patterns of price and wage adjustment inEuropean firms and on the extent of nominal rigidities. It uses a unique dataset collectedthrough a firm-level survey conducted in a broad range of countries and covering varioussectors. Several conclusions are drawn...

This paper assesses the degree of wage flexibility in Luxembourg using anadministrative data set on individual base wages covering the entire economy over theperiod 2001-2006 with monthly frequency. We find that the wage flexibility at thediscretion of the firm is rather low once we limit...

To explain potential sources of wage rigidity this article analyzes a model of reciprocalkindness applied to a repeated ultimatum game with changing and nonzeroconflict payoffs. The model is also tested in a laboratory experiment. The resultsare compatible with the rentsharingapproach to wage...
