Among the most important and robust violations of rationality are the attraction and the compromise effects. The compromise effect refers to the tendency of individuals to choose an intermediate option in a choice set, while the attraction effect refers to the tendency to choose an option that...

Models of choice where agents see others as less sophisticated than themselves have significantly different, sometimes more accurate, predictions in games than does Nash equilibrium. When it comes to mechanism design, however, they turn out to have surprisingly similar implications. This paper...

Incorporating bounded rationality into the classic consumer theory setting, we study the testable implications of a consumer who may have trouble consistently assessing her subjective tastes. Our model of E-Rationalizability, which bounds the consumer's misperception of her marginal rates of...

A decision maker may not perfectly maximize her preference over the feasible set. She may feel it is good enough to maximize her preference over a sufficiently large consideration set; or just require that her choice is sufficiently well-ranked (e.g., in the top quintile of options); or even...

Each period, a principal must assign one of two agents to a new task. Profit is stochastically higher when the agent is qualified for the task, but the principal cannot observe qualification. Her only decision is which of the two agents to assign, if any, given the public history of selections...

Bounded rationality theories are typically characterized over exhaustive data sets. We develop a methodology to understand the empirical content of such theories with limited data, adapting the classic, revealed-preference approach to new forms of revealed information. We apply our approach to...

The set of fair (i.e. envy free and efficient) allocation rules may be empty in wellbehaved pure exchange economies if the agents are asymmetrically informed at the time of contracting. In addition, there may exist efficient allocation rules such that every agent envies another.

I prove that the Nash bargaining solution is the only solution to satisfy ‘Disagreement Point Convexity’ and ‘Midpoint Domination’. I explain how this improves previous results obtained by Chun (1990) and by Dagan et al. (2002).

I adapt a reduction process introduced by Serrano and Volij (1998) so that the reduced games of convex-valued games are convex-valued. I use the corresponding consistency property and its converse to axiomatize the inner core for games that are convex-valued, non-level and smooth.

Our concern is the extension of the theory of the Shapley value to problems involving externalities. Using the standard axiom systems behind the Shapley value for an arbitrary exogenous coalition structure leads to the identification of bounds on players’ payoffs around an...
