We analyze the cost savings potential with regard to administration and management costs by merging Public Employment Accident Insurance Funds (Öffentliche Unfallkassen) in Germany. Our data base consists of the annual reports of the public statutory accident insurance funds from 1999 to 2005....

We investigate the positive and normative implications of a tax on financial market transactions in a dynamic general equilibrium model, where agents face idiosyncratic liquidity shocks and financial trading is essential. Our main finding is that agents' portfolio choices display a pecuniary...

This paper addresses the discussion between economic power and the power of politics with particular focus on financial markets. After general reflections about the economic basis of power, the paper discusses in a general equilibrium framework how financial innovations can lead to risk creation...

We study the effect of public information on collective decision-making in a committee with members of both common and conflicting interests. We show that the set of preferences that allow for the existence of an informative voting equilibrium can be heavily restricted by the presence of a...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...

We study the effects of deliberation on collective decisions. In a series of experiments, we vary groups' preference distributions (between common and conflicting interests) and the institutions by which decisions are reached (simple majority, two-thirds majority, and unanimity). When...

No voters cast their votes based on perfect information, but better educated and richer voters are on average better informed than others. We develop a model where the voting mistakes resulting from low political knowledge reduce the weight of poor voters, and cause parties to choose political...

We derive a necessary and sufficient condition for the existence of equilibria with only two active players in the all-pay auction with complete information and identity-dependent externalities. This condition shows that the generic equilibrium of the standard all-pay auction is robust to the...

Many countries are forging ahead with convenient balloting methods, in particular electronic and postal voting, in order to re-engage voters. In this paper, we test whether the cost reductions with postal voting increase turnout. The empirical analysis is based on a newly collected data set on...

Traditionally, the virtue of democratic elections has been seen in their role as means of screening and sanctioning shirking public officials. This paper proposes a novel rationale for elections and political campaigns considering that candidates incur psychological costs of lying, in particular...
