The standard framework for analyzing games with incomplete information models players as if they form beliefs about their opponents' beliefs about their opponents' beliefs and so on, that is, as if players have an infinite depth of reasoning. This strong assumption has nontrivial implications,...

By identifying types whose low-order beliefs - up to level li - about the state of nature coincide, we obtain quotient type spaces that are typically smaller than the original ones, preserve basic topological properties, and allow standard equilibrium analysis even under bounded reasoning. Our...

In the Solidarity Game (Selten and Ockenfels, 1998), two "rich" persons can support a "poor" one. A strong positive correlation between one rich person's solidarity contribution and his expected contribution of the other is observed. This paper investigates the causality behind this correlation....

We investigate the relationship between religion and trust. Using a questionnaire, we measure: i) general religiosity, and; ii) the extent of religious beliefs, experience, and ritual. These are then analyzed with behaviour in a trust game (Berg et al., Games and Economic Behaviour, 1995), which...

Since campaign finance reform is usually motivated by the concern that existing legislation can not effectively prevent campaign contributions to 'buy favors', this paper assumes that contributions influence political decisions. But, given that it is also widely recognized that interest groups...

In models of non-deterministic contest, players exert irreversible effort in order to increase their probability of winning a prize. The most prominent functional form of the win probability in the literature is the so-called logit" contest success function. We provide a simple micro-foundation...

We examine the consequences of lobbying and vote buying, assuming this practice were allowed and free of stigma. Two .lobbyists. compete for the votes of legislators by oþering up-front payments to the legislators in exchange for their votes. We analyze how the lobbyists.budget constraints and...

We examine the consequences of vote buying, assuming this practice were al-lowed and free of stigma. Two parties compete in a binary election and may purchase votes in a sequential bidding game via up-front binding payments and/or campaign promises (platforms) that are contingent upon the...

We de.ne and analyze a strategic topology on types in the Harsanyi-Mertens-Zamir universal type space, where two types are close if their strategic behavior is similar in all strategic situations. For a .xed game and action de.ne the distance be-tween a pair of types as the diþerence between...

In games with costly signaling, some equilibria are vulnerable to deviations which could be unambiguously interpreted as coming from a unique set of Sender-types. This occurs when these types are precisely the ones who gain from deviating for any beliefs the Re-ceiver could form over that set....
