We study competitive market outcomes in economies where agents have other-regarding preferences (ORPs). We identify a separability condition on monotone preferences that is necessary and sufficient for one's own demand to be independent of the allocations and characteristics of other agents in...

Harassment bribes - payments people give in order not to be denied what they are legally entitled to - are common in for example India. Kaushik Basu recently made a radical proposal to reduce its occurrence: Legalize the act of giving the bribe and double the fine for accepting the bribe! We...

Harassment bribes - payments people give in order not to be denied what they are legally entitled to – are common in for example India. Kaushik Basu recently made a '’radical'’ proposal to reduce its occurrence: Legalize the act of giving the bribe and double the fine for accepting the...

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 subject’s...

Land conflicts in developing countries are costly. An important policy goal is to create respect for borders. This often involves mandatory, expensive interventions. We propose a new policy design, which in theory promotes neighborly relations at low cost. A salient feature is the option to...

Evidence suggests that whether or not people dislike lying is situation-dependent. We argue that the theory of simple guilt can accommodate this well.

Pareto equilibria in multicriteria games can be computed as the Nash equilibria of scalarized games, obtained by assigning weights to the separate criteria of a player. To analysts, these weights are usually unknown. This paper therefore proposes ideal equilibria, strategy profiles that are...

We extend the consistency principle for strategic games (Peleg and Tijs (1996)) to apply to solutions which assign to each game a collection of product sets of strategies. Such solutions turn out to satisfy desirable properties that solutions assigning to each game a collection of strategy...

Gneezy (2005) reports evidence indicating that in some settings people do not like to lie. In many other situations people do not suffer when they lie. We argue that the theory of simple guilt can accommodate these observations.

Reciprocity can be a powerful motivation for human behaviour. Scholars argue that it is relevant in the context of private provision of public goods. We examine whether reciprocity can resolve the associated coordination problem. The interaction of reciprocity with cost-sharing is critical....
