We explore sequential voting in symmetric two-option environments. We show that the (informative) symmetric equilibria of the simultaneous voting game are also equilibria in any sequential voting structure. In unanimity games, (essentially) the whole set of equilibria is the same in all...

We consider discrete versions of independent, private-value, first-price auctions. We show for any fixed finite set of possible bids, if the number of participants is large enough, then the set of rationalizable bids involves all players bidding the highest bid that is lower than their private...

A long-standing conjecture is that winner-take-all games such as patent races lead to the survival of risk-takers and the extinction of risk-averters. In many species a winner-take-all game determines the males' right to reproduce, and the same argument suggests that males will evolve to be...

In a self-confirming equilibrium, each player correctly forecasts the actions that opponents will take along the equilibrium path, but may be mistaken about the way that opponents would respond to deviations. This models a steady state of a learning process in which players observe actions...

We develop an extension of Luce's random choice model to study violations of the weak axiom of revealed preference. We introduce the notion of a stochastic preference and show that it implies the Luce model. Then, to address well‐known difficulties of the Luce model, we define the attribute...

We introduce a notion of coarse competitive equilibrium (CCE), to study households' inability to tailor their consumption to the state of the economy. Our notion is motivated by limited cognitive ability (in particular attention, memory, and complexity) and it maintains the complete market...

We analyse preferences over finite decision problems in order to model decision-makers with "changing tastes". we provide conditions on these preferences that identify the Strotz model of consistent planning. building on an example given by <xref ref-type="bibr" rid="R8">Peleg and Yaari (1973)</xref>, we show that for problems with...
