Abstract
Two anonymous referees have provided very valuable comments and suggestions. We have also benefited from discussions at seminars at the Universities of Bonn, Dortmund and Dresden and at the conferences of Euresco, the European Economic Association and the Verein für Socialpolitik. This paper was partly written while Haupt was visiting the Economics Department at the University of Colorado at Boulder. He is very grateful to the members of the department, particularly to Eckhard Janeba, for their hospitality and for stimulating discussions, and to the Fritz Thyssen Stiftung for funding his research visit. We also thank the Deutsche Forschungsgemeinschaft DFG for financial support.
