Both social psychology and experimental economics empirically investigate social dilemmas. However, these two disciplines sometimes use different notions for very similar scenarios. While it is irrelevant for economists whether an experimental public-good game is conceptualised as a take-some or...

The purpose of this article is to provide an alternative antitrust model to the mainstream model that is used in competition policy. I call it the Institutional-Evolutionary Antitrust Model. In order to construct an antitrust model one needs both empirical knowledge and considerations of how to...

Der Jurist ist im Umgang mit Unsicherheit vor besondere Schwierigkeiten gestellt: Sein Instrumentarium ist weitgehend darauf ausgerichtet, mit statischen Situationen aufgrund einer präzisen Entscheidungsregel umzugehen. Unsicherheit und Risiko aber erlauben zunächst keine Präzision und keine...

This paper compares two instruments for implementing producer responsibility for used cars. The German regulatory solution, relying on take-back obligations for producers, free for the last holder, is contrasted with a rule of partial cost recovery. It is shown that the cost-recovery rule saves...

The analysis of common goods needs to look very carefully at the characteristics of the goods and of the social situations of their provision.

We consider temporal aggregation of stationary and nonstationary time series with short memory, long memory and antipersistence, within the framework of fractional autoregressive processes. Asymptotically, long memory and antipersistence are preserved whereas short memory components vanish. In...

In this paper data-driven algorithms for fitting SEMIFAR models (Beran, 1999) are proposed. The algorithms combine the data-driven estimation of the nonparametric trend and maximum likelihood estimation of the parameters. For selecting the bandwidth, the proposal of Beran and Feng (1999) based...
