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...

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...

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...

Existiert ein Zusammenhang zwischen Arbeitslosigkeit und Kriminalität in Deutschland? Würde ein Rückgang der Arbeitslosigkeit auch einen Teil des Kriminalitätsproblems lösen? Diese beiden Fragen stellen den Ausgangspunkt der Untersuchung dar. Mit Hilfe von Daten für die deutschen...

Rational partisan theory of political business cycles suggests differences in inflation under left-wing and right-wing governments. It also suggests temporary post-electoral booms after election of left-wing governments and temporary recessions after election of right-wing ones. However, the...

Common wisdom holds that the introduction of a non-binding minimum wage is irrelevant for actual wages and employment. Empirical and experimental research, however, has shown that the introduction of a minimum wage can raise even those wages that were already above the new minimum wage. In this...

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...

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...
