How do the media affect public support for democratic institutions in a fragile democracy? What role do they play in a dictatorial regime? We study these questions in the context of Germany of the 1920s and 1930s. During the democratic period, when the Weimar government introduced progovernment...

We experimentally examine the effects of price competition in markets for expe-rience goods where sellers can build up reputations for quality. We compare price competition to monopolistic markets and markets where prices are exogenously fixed (somewhere between the endogenous oligopoly and...

Imitating the best strategy from the previous period has been shown to be an important heuristic, in particular in relatively complex environments. In this experiment we test whether subjects are more likely to use imitation if they are under stress. Subjects play a repeated Cournot oligopoly....

In this note we shall discuss a concept that - despite its prominence in both Hume (1739) and Smith (1759), its obvious relevance for social behavior, and its not so infrequent use in colloquial language - has never gained a foothold in economic theory: the concept of empathy. Specifically, we...

We study an investment experiment conducted with a representative sample of German households. Respondents invest in a safe asset and a risky asset whose return is tied to the German stock market. Experimental investments correlate with beliefs about stock market returns and exhibit desirable...

I show theoretically that applying the model of Köszegi and Rabin (2006) to a simple purchasing decision where consumers are ex-ante uncertain about the price realisation, gives - when changing the underlying distribution of expected prices - rise to counterintuitive predictions in contrast...

In a laboratory experiment designed to capture key aspects of the interaction be-tween physicians and patients in a stylized way, we study the effects of medical insurance and competition in the guise of free choice of physician. Medical treat-ment is an example of a credence good: only the...

I estimate permanent and transitory tax-price and income elasticity of charitable giving in Germany using a rich panel data of tax return for the years 2001-2006. Income tax reforms were implemented in 2004 and 2005. The results suggest that the permanent tax-price elasticity varies...

Although microfinance institutions across the world are moving from group lending towards individual lending, this strategic shift is not substantiated by sufficient empirical evidence on the impact of both types of lending on borrowers. We present such evidence from a randomised field...

We use a randomised controlled trial (RCT) to analyse the impact of microcredit on poverty reduction in Bosnia and Herzegovina. The study population are loan appli-cants that would normally have just been rejected based on regular screening. We find that access to credit allowed borrowers to...
