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...

We study the nature of individual demands for environmental regulation and for trade openness in the general equilibrium of a small open economy where the environment is an input to production. Differences in the ability of individuals to afford private mitigation of the adverse consequences of...

It is regularly stated that political fragmentation has negative effects on reforms leading to delays or even blockades. This connection is reflected in the ‘weak government hypothesis’ arguing that fragmented governments create higher budget deficits. Although the assumption seems logical,...

I discuss instances where a committee wants to deviate from the simple majority rule by adopting an alternative voting scheme for two consecutive binary ballots. The alternative voting rule, called Minority Voting as an Exception (MVE), works as follows: In the first ballot a b-majority rule is...

In many organizations, decisions are taken by unanimity giving each member veto power. We analyze a model of an organization in which members with heterogenous productivity privately contribute to a common good. Under unanimity, the least efficient member imposes her preferred effort choice on...

This paper presents empirical evidence of a positive effect of council size on government spending using a data set of 2,056 municipalities in the German state of Bavaria over a period of 21 years. We apply a regression discontinuity design to avoid an endogeneity bias. In particular, we exploit...

The paper models the incentives of a politician to delegate the decision making power in a sovereign wealth fund to an independent external manager. It formalizes the learning-effects as well as the increase of transparency of the SWF and the rise of investment possibilities associated with...

This paper is the first to provide evidence of efficient taxation of groups with heterogeneous levels of 'tax morale'. We set up an optimal income tax model where high tax morale implies a high subjective cost of evading taxes. The model predicts that 'nice guys finish last': groups with higher...

Median voter theorem has been used in many economic environments including law enforcement. Assumptions of the median voter theorem, however, are generally violated in lawenforcement models. Moreover, it is impossible to have agents with "opposite equilibrium preferences" over enforcement levels...
