摘要：We take school admission mechanisms to the lab to test whether the widely-used manipulable Immediate Acceptance mechanism disadvantages students of lower cognitive ability and whether this leads to ability segregation across schools. Results show this to be the case: lower ability participants receive lower payoffs and are over-represented at the worst school. Under the strategy-proof Deferred Acceptance mechanism, payoff differences are reduced, and ability distributions across schools harmon...

摘要：There is ample evidence that the number of players can have an important impact on the cooperation and coordination behavior of people facing social dilemmas. With extremely few exceptions, the literature on cooperation assumes common knowledge about who is a player and how many players are involved in a certain situation. In this paper, we argue that this assumption is overly restrictive, and not even very common in real-world cooperation problems. We show theoretically and experimentally tha...

摘要：Fictitious play is a simple and widely studied adaptive heuristic for playing repeated games. It is well known that fictitious play fails to be Hannan consistent. Several variants of fictitious play including regret matching, generalized regret matching and smooth fictitious play, are known to be Hannan consistent. In this note, we consider sampled fictitious play: at each round, the player samples past times and plays the best response to previous moves of other players at the sampled time po...

摘要：We suppose that players in a cooperative game are located within a graph structure, such as a social network or supply route, that limits coalition formation to coalitions along connected subsets within the graph. This in turn leads to a more general study of coalitional games in which there are arbitrary limitations on the collections of coalitions that may be formed. Within this context we define a generalisation of the Shapley value that is studied from an axiomatic perspective. The resulti...

摘要：This paper studies large population (nonatomic) potential games with continuous strategy sets. We define such games as population games in which the payoff function is equal to the gradient of a real-valued function called the potential function. The Cournot competition model with continuous player set and continuous strategy set is our main example and is analyzed in detail. For general potential games, we establish that maximizers of potential functions are Nash equilibria. For a particular ...

摘要：When a polluted river passes through several different regions, a challenging question is how should the costs for cleaning the river be shared among the regions. Following Ni and Wang (2007) and Dong et al. (2012), we first show that the Upstream Equal Sharing method and the Downstream Equal Sharing method coincide with the conjunctive permission value (van den Brink and Gilles, 1996) of an associated game with a permission structure, which is obtained as the Shapley value of an associated re...

摘要：The ratchet effect is a phenomenon where workers strategically restrict their output because they anticipate high levels of productivity will be met with increased expectations in the future. Using a real-effort work task and a piece-rate incentive scheme, we investigate the presence of the ratchet effect using two different methods for evaluating worker productivity: (i) when productivity is evaluated individually, and (ii) when productivity is evaluated collectively among a group of workers....

摘要：We present a model of repeated games in large two-sided networks between clients and agents in the presence of third-party observability networks via which clients share information about past transactions. The model allows us to characterize cooperation networks networks in which each agent cooperates with every client that is connected to her. To this end, we show that: [1] an agent a's incentives to cooperate depend only on her beliefs with respect to her local neighborhood-a subnetwork tha...

摘要：This paper investigates social influences on attitudes to risk and reanalyses how risk taking varies with relative position and inequality. Individuals with low initial wealth, about to participate in a tournament with richer opponents, may take fair gambles even though they are risk averse in both consumption and tournament rewards. It is shown that this risk taking decreases in the inequality of initial endowments, but in contrast it increases in the inequality of tournament rewards. (C) 201...

摘要：Psychophysics studies suggest that our perception of time is different from the objective passage of time. Economics research emphasizes that the value of a reward depends on the delay involved. In this paper, we combine both strands and estimate time perception and time discounting functions at the individual level in an incentivized controlled laboratory environment. We find a negative and statistically significant correlation between time perception and time discounting: subjects who overes...
