摘要：We study a model of strategic network formation prior to a Manea (2011a) bargaining game: ex ante homogeneous players form costly undirected links, anticipating expected equilibrium payoffs from the subsequent bargaining game. Assuming patient players, we provide a complete characterization of generically pairwise stable networks: specific unions of separated pairs, odd circles, and isolated players constitute this class. We also show that many other structures, such as larger trees or unbalan...

摘要：By extending the equilibrium concepts of Koszegi and Rabin (2006, 2007), this paper analyzes the strategic interaction of expectation-based loss-averse players. For loss-averse players with choice-acclimating expectations, the utility from playing a mixed strategy is not linear but convex in the probabilities they assign to their pure strategies. As a consequence, they are generally unwilling to randomize and an equilibrium may fail to exist. For players with choice-unacclimating expectations,...

摘要：In this paper, we revisit the two-bidder asymmetric all-pay auction of Amann and Leininger (1996) by allowing interdependent values and correlated signals. Both values and signals are distributed on continuous supports. We provide conditions for the existence and uniqueness of a monotone pure-strategy equilibrium (MPSE), and constructively characterize the MPSE when it exists. We find that given the marginal distributions of the signals, the equilibrium allocation is solely determined by how b...

摘要：The ability to form shared intentions and adjust one's choices in collaboration with others is a fundamental aspect of human nature. We discuss the forces that act for and against the evolution of this ability. In contrast to altruism and other non-fitness maximizing preferences, for large classes of games the ability to form shared intentions proliferates when rare without requiring group selection or assortativity in matching.

摘要：We compare three approaches to test for guilt aversion in two economic experiments. The first approach elicits second-order beliefs using self-reports. The second approach discloses first-order beliefs of matched players to decision makers, which are taken as exogenous second-order beliefs of decision makers. The third approach lets decision makers make choices conditional on a sequence of possible first-order beliefs of matched players. We find that the first and third approach generate simil...

摘要：I analyze Nash implementation when agents might use an exogenous tie-breaking rule to choose among the messages they are materially indifferent between. If the planner is endowed with the knowledge of the rule, this might expand or shrink the set of implementable social choice correspondences depending on the particular rule used by the agents. If the planner is not endowed with the knowledge of the rule, then the problem of implementation is almost equivalent to double implementation in Nash ...

摘要：We investigate our capacity to attribute preferences to others. This ability is intrinsic to game theory, and is a central component of Theory of Mind, perhaps the capstone of social cognition. This component of theory of mind allows individuals to learn more rapidly in strategic environments with an element of novelty. We show that the capacity to attribute preferences yields an advantage over less sophisticated approaches to strategic interaction (e.g. reinforcement learning) because it allo...

摘要：Evidence from studies in international relations, the politics of reform, collective action and price competition suggests that economic agents in social dilemma situations cooperate more to avoid losses than in the pursuit of gains. To test whether the prospect of losses can induce cooperation, we let experimental subjects play the traveler's dilemma in the gain and loss domain. Subjects cooperate substantially more over losses. Furthermore, our results suggest that this treatment effect is b...

摘要：We study cultural diffusion in a random network where the transition probabilities are determined by a cultural transmission technology with endogenous vertical transmission rates (a la Bisin and Verdier, 2001). We present a two-way epidemic model in which both the infection and the recovery rates are endogenous and depend on the topology of the network. We characterize two balancing conditions satisfied by the network degree distribution and the vertical transmission rate distribution to ensu...

摘要：We study a social learning model with payoff externalities in which one of two state dependent games is chosen at random and then played repeatedly by a different group of agents. Each generation observes the history of actions and receives conditionally independent private signals about the realized game. We show that with probability one, the play converges to the set of equilibria of an appropriate convex combination of the two state games. We provide a necessary and sufficient condition on...
