Networks can have an important effect on economic outcomes. Given the complexity of many of these networks, agents will generally not know their structure. We study the sensitivity of game-theoretic predictions to the specification of players’ (common) prior on the network in a setting where...

Networks can have an important effect on economic outcomes. Given the complexity of many of these networks, agents will generally not know their structure. We study the sensitivity of game-theoretical predictions to the specification of players’ (common) prior on the network in a setting where...

Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete.We report a...

This paper presents a principal-agent model where the agent has multiple, or imprecise, beliefs. We model this situation formally by assuming the agent's preferences are incomplete. One can interpret this multiplicity as an agent's limited knowledge of the surrounding environment. In this...

In many contexts, players interact only with a subset of the whole population, i.e., players interact on a network. This paper a setting in which players are located on a network and play a fixed game with their neighbors. Players have incomplete information on the network structure. They have a...

We study several group testing models with and without processing times.The objective is to choose an optimal group size for pooled screening of a contaminated population so as to collect a prespeciffied number of good items from it with minimumtesting expenditures.The tested groups that are...

In the games with population uncertainty introduced in this paper, the number and identity of the participating players are determined by chance.Games with population uncertainty are shown to include Poisson games and random-player games.The paper focuses on those strategy profiles that are most...

We describe non-cooperative game models and discuss game theoretic solution<br/>concepts. Some applications are also noted. Conventional theory focuses on the<br/>question ‘how will rational players play?’, and has the Nash equilibrium at its core.<br/>We discuss this concept and its interpretations, as...
