Least-Unmatched Price Auctions have become a popular format of TV and radio shows. Increasingly,they are also applied in internet trading. In these auctions the lowest single (unique)bid wins. We analyze the game-theoretic solution of least unmatched price auctions when prize,bidding cost and...

Is culture an important variable to explain whether groups can successfully provide public goods? A wealth of empirical evidence on both industrialized and developing countries shows that cooperation levels decrease in the presence of ethnic divisions. Although several laboratory works deal with...

This Paper studies budget processes, both theoretically and experimentally. We compare the outcomes of bottom-up and top-down budget processes. It is often presumed that a top-down budget process leads to a smaller overall budget than a bottom-up budget process. We show, using structurally...

We present a theoretical model of a linear public good game in which heterogeneous players express social approval after observing contributions. The model explains how social approval is expressed and predicts positive contributions if subjects have a preference for social approval. Using a...

We use a two-person public goods experiment to distinguish betweene±ciency and fairness as possible motivations for cooperative behavior.Asymmetric marginal per capita returns allow only the high-productivityplayer to increase group payo®s when contributing positive amounts....

I conduct an experiment to assess whether majority voting on a nonbindingsharing norm affects subsequent behavior in a dictator game. Ina baseline treatment, subjects play a one shot dictator game. In a votingtreatment, subjects are first placed behind a ‘veil of ignorance’ and vote onthe...

In a large scale newspaper experiment 5,132 readers of the German weekly, Die Zeit, participated in a three-person bargaining game. In our data analysis we focus on (1) the influence of age, gender, profession and the medium chosen for participation on bargaining behavior and on (2) the external...

We analyze the effects of introducing asymmetric information andexpectations in the investment game (Berg et al., 1995). In our experiment,only the trustee knows the size of the surplus. Subjects’expectations about each other’s behavior are also elicited. Our resultsshow that average payback...
