This paper analyses competition of moral norms and institutions in a society where a fixed share of people unconditionally complies with norms and the remaining people act selfishly. Whether a person is a norm-complier or selfish is private knowledge. A model of voting-by-feet shows that those...

Psychological game theory can provide rational-choice-based framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically and explore empirical relevance experimentally. In a 2×2 design of one-shot public good games we show that frames affect...

Psychological game theory can help provide a rational choice explanation of framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically, and explore the empirical relevance experimentally. In a 2×2 design of one-shot public good games we show that...

This paper contributes to the ongoing methodological debate on context-free versus in-context presentation of experimental tasks. We report an experiment using the paradigm of a bribery experiment. In one condition, the task is presented in a typical bribery context, the other one uses abstract...

We develop an evolutionary model of growth in which agents choose how to allocate their time between private and social activities. We argue that a shift from social to private activities may foster market-based growth, but also generate social poverty. Within a formal framework that merges a...

This paper investigates the impact of game presentation dependent on ethnical affiliation. Two games representing the same logical and strategical problem are introduced. Presented games are continuous prisoner’s dilemma games where decision makers can choose an individual level of cooperation...

This paper introduces a two-sided methodological framework for   studies on cooperation based on a new game design. Presented games are continuous prisoner's   dilemma games with positive and negative presentations of an identically structured   decision problem. Decision makers can choose an...

Hotelling’s famous ‘Principle of Minimum Differentiation’ asserts that two firms engaging in spatial competition with fixed prices will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not...

I consider a situation, where the agent can acquire payoff-relevant information either before or after the contract is signed. To raise efficiency, the principal might solicit information; to retain all surplus, however, she must prevent precontractual information gathering. The following class...

This paper analyzes truthtelling incentives in pre-vote communication in heterogeneous committees. We generalize the classical Condorcet jury model by introducing a new informational structure that captures consistency of information. In contrast to the impossibility result shown by Coughlan...
