摘要：We report an experiment examining a simple clearing house model that generates price dispersion. According to this model, price dispersion arises because of consumer heterogeneity-some consumers are informed and simply buy from the firm offering the lowest price, while the remaining consumers are captive and shop based on considerations other than price. In our experiment we observe substantial and persistent price dispersion. We find that, as predicted, an increase in the fraction of informed...

摘要：We examine the strategic behavior of leaders and followers in sequential duopoly experiments with errors in communication: followers either perfectly observe the leaders' actions or else they observe nothing. Consistent with the theory, the leaders in our experiments enjoy a greater first-mover advantage when followers observe their actions with higher probability, albeit their advantage is weaker than the theory predicts and is only weakly increasing with the probability that their actions wi...

摘要：The storable votes mechanism is a voting method for committees that meet periodically to consider a series of binary decisions. Each member is allocated a fixed budget of votes to be cast as desired over the sequence of decisions. This provides incentives for voters to spend more votes on those decisions that matter to them more, typically generating welfare gains over standard majority voting with non-storable votes. Equilibrium strategies have a very intuitive feature-the number of votes cas...

摘要：We propose two cost-sharing theories in which agents demand comparable commodities and are responsible for their own demand. Under partial responsibility, agents are not responsible for the asymmetries of the cost function: two agents consuming the same quantity pay the same price; this holds under full responsibility only if the cost function is symmetric. If the cost function is additively separable, each agent pays her stand-alone cost under full responsibility; this holds under partial res...

摘要：The well-being of agents is often directly affected by their beliefs, in the form of anticipatory feelings such as anxiety and hopefulness. Economists have tried to model this effect by introducing beliefs as arguments in decision makers' vNM utility function. One might expect that such a model would be capable of explaining anomalous attitudes to information that we observe in reality. We show that the model has several shortcomings in this regard, as long as Bayesian updating is retained. (c...

摘要：We show that games of strategic complements, or substitutes, with aggregation are pseudopotential games. The upshot is that they possess Nash equilibria in pure strategies (NE), even if the strategy sets are not convex; and that various dynamic processes converge to NE. In particular, NE exist in Cournot oligopoly with indivisibilities in production. Our notion of aggregation is quite general and enables us to take a unified view of several disparate models.

摘要：We report on a design of a Turing tournament and its initial implementation to learning in repeated 2-person games. The principal objectives of the tournament, named after the original Turing Test, are (1) to find teaming algorithms (emulators) that most closely simulate human behavior, (2) to find algorithms (detectors) that most accurately distinguish between humans and machines, and (3) to provide a demonstration of how to implement this methodology for evaluating models of human behavior. ...

摘要：We consider a network game where the nodes of the network wish to form a graph to route traffic between themselves. We present a model where costs are incurred for routing traffic, as well as for a lack of network connectivity. We focus on directed links and the link stability equilibrium concept, and characterize connected link stable equilibria. The structure of connected link stable networks is analyzed for several special cases. (c) 2005 Elsevier Inc. All rights reserved.

摘要：We present a formal model of political competition under approval voting which allows for endogenous candidate entry. Our analysis yields a number of novel insights. First, we develop a notion of sincere voting behavior under approval voting, called relative sincerity. We then show that the relatively sincere voting behavior is consistent with the strategic calculus of voting. Second, we show that in a one-dimensional model with distance preferences, equilibria in relatively sincere strategies...
