In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on investment behaviour in public goods settings. Our models build on the idea that voluntary contributions to the supply of a public good might be motivated by...

We analyze union behavior in a model with membership dynamics and compare the labor market outcomes to static union models. Based on empirical findings we modify standard models and show that the well-known result that static models overstate distortions caused by unions only holds in the...

In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on future investment behaviour in public good settings. Our models build on the idea that voluntary contributions to the supply of a public good might be...

We analyse the role of bargaining centralisation when both the union's outside option and union membership are endogenous and considered in a dynamic framework. A dynamic two-sector model is developed where the wage rate in the first sector is either set by a monopoly union or is the result of...

The paper analyses the links between a binding minimum wage and union bargaining. A dual labour market model is developed where the first sector outcome is characterised by bargaining between unions and firms, while in the second sector firms have to pay a statutory minimum wage. It is shown...

The paper analyses the welfare effects of union bargaining centralisation in a simple general equilibrium model. A two-sector model is developed where the wage rate in the first sector is either set decentralised by a small union at the firm level or centralised by a large union covering all...

This paper analyses bargaining over an incentive compatible contract in a moral hazard framework. We introduce the Kalai-Smorodinsky bargaining solution and compare the outcome with the commonly applied Nash solution. Whether worker's effort is higher in the Nash or the Kalai-Smorodinsky...

Die Studie geht in zwei Schritten vor: Im ersten Teil werden die Konsequenzen des Bevölkerungswandels auf den Arbeitsmarkt in Sachsen aufgezeigt. Für diesen Zweck wird ein Referenzszenario des sächsischen Arbeitsmarktes bis 2020 entwickelt. Es zeigt sich, dass sich die Arbeitsmärkte je nach...

Die Diskussion um den Starttermin für die Maut für Lastkraftwagen in Deutschland ist seit Sommer 2003 ein Dauerbrenner auf der politischen Agenda. In diesem Artikel soll diskutiert werden, was das deutsche Mautsystem leisten kann und wie es – mit einigen Modifizierungen – als...
