Extensive research on human cooperation in social dilemmas has shown that individuals condition their behaviour upon the behaviour of others. However, few attempts have been made to disentangle the motivations backing conditional cooperation. We try to assess the relative importance of three...

We present a model of price leadership on homogeneous product markets where the price leader is selected endogenously. The price leader sets and guarantees a sales price to which followers can adjust according to their individual supply functions. The price leader then clears the market by...

We present a model of price leadership on homogeneous product markets where the price leader is selected endogenously. The price leader sets and guarantees a sales price to which followers adjust according to their individual supply functions. The price leader clears the market by serving the...

We study two person-betting games with inconsistent commonly know beliefs, using an experimental approach. In our experimental games, participants bet against one another, each bettor choosing one of two possible outcomes, and payoff odds are know at the time bets are placed. Bettors' beliefs...

Collusive agreements are often observed in procurement auctions. They are probably more easily achieved when competitors’ costs are easily estimated. If, however, the individual costs of bidders are private information, effective ring formation is difficult to realize. We compare...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

Bidding challenges learning theories since experiences for the same bid vary stochastically: the same choice can result in a gain or a loss. In such an environment the question arises how the nearly universally documented phenomenon of loss aversion affects the adaptive dynamics. We analyze the...

Relying on the specific example of ultimatum bargaining experiments this paper explores the possible role of empirical knowledge of behavioural "norm(ative) facts" within the search for an inter-personal (W)RE - (Wide) Reflective Equilibrium on normative issues. Assuming that pro-social...

We experimentally investigate how affective processes influence proposers' and responders' behaviour in the Ultimatum Game. Using a dual-system approach, we tax cognitive resources through time pressure and cognitive load to enhance the influence of affective processes on behaviour. We find that...
