摘要：I study a two-period matching model where one side of the market (e.g. workers) have an option to invest and delay matching in the first period. Investment increases each agent's matching surplus in the second period, by a magnitude of the worker's investment ability in the match pair. Assuming each worker's investment ability is her private information that unfolds in the second period, I define a notion of sequential stability, and show that the set of sequentially stable outcomes is a super...

摘要：In cooperative games, the coalition structure core is, despite its potential emptiness, one of the most popular solutions. While it is a fundamentally static concept, the consideration of a sequential extension of the underlying dominance correspondence gave rise to a selection of non-empty generalizations. Among these, the payoff-equivalence minimal dominant set and the myopic stable set are defined by a similar set of conditions. We identify some problems with the payoff-equivalence minimal ...

摘要：We propose a social learning model where agents choose who to communicate with based on the trade-off between collecting information and influencing others' actions. Like-minded people reveal more truthful information, but talking to someone different makes an agent more likely to influence another person's action, because like-minded people will take similar actions anyway. In our model agents start with heterogeneous priors about an unknown state of the world. First agents form coalitions of...

摘要：An abstract game consists of a set of states, preferences over states, and an effectivity correspondence specifying what coalitions are allowed to replace one state by another one. Agents are called farsighted if, when deciding whether to support a coalition's move, they compare the status quo to the long term outcome following their deviation. Yet, this definition of farsightedness ignores a coalition's option to remain at the status quo allowing another coalition to move: agents are not full...

摘要：We study the bilateral trade problem: one seller, one buyer and a single, indivisible item for sale. It is well known that there is no fully-efficient and incentive compatible mechanism for this problem that maintains a balanced budget. We design simple and robust mechanisms that obtain approximate efficiency with these properties. We show that even minimal use of statistical data can yield good approximation results. We then demonstrate how a mechanism for this simple bilateral-trade problem ...

摘要：This paper endogenizes a monopolist's choice between selling and renting in a non anonymous durable goods setting with short-term commitment, by allowing for contracts that determine the good's allocation not only at the beginning but also at the end of a given period. We show that the revenue-maximizing menu of contracts features screening by mode of trade when future trade is subject to frictions and the monopolist is more patient than consumers. Selling to high types while renting to low ty...

摘要：Barter and commodity markets have been ubiquitous throughout history, suggesting that humans are good at exploiting profitable exchange opportunities. This paper studies our ability to trade through a developmental approach. We present a market experiment involving children who have not yet fully developed trading habits and are relatively unfamiliar with the concept of money. Namely, we ask 117 children aged 5 to 8 to trade in situations in which efficient market outcomes can either be achiev...

摘要：On the basis of a single-period, guns-versus-butter, complete-information model in which two agents dispute control over an insecure portion of their combined output, we study the choice between a peace agreement that maintains the status quo without arming (or unarmed peace) and open conflict (or war) that is possibly destructive. With a focus on outcomes that are immune to both unilateral deviations and coalitional deviations, we find that, depending on war's destructive effects, the degree ...

摘要：We examine the roles of (slightly weakened versions of) the observable substitutability condition and the observable substitutability across doctors condition of Hatfield et al. (2021) in many-to-many matching with contracts. We modify the standard cumulative offer algorithm to find stable outcomes and prove new results on the existence of stable outcomes. It is remarkable that size monotonicity at the offer-proposing side is essential for the existence result under observable substitutability...

摘要：The signals used in persuasion mechanisms in practice typically satisfy two well-studied simple properties: (i) they partition an ordered state space into intervals, and (ii) they do not recommend lower actions at higher states. These properties have been studied-often separately-in the Bayesian persuasion literature, where conditions for the optimality of such signals are provided in various settings. The two properties can be defined only when the action and the state space are ordered. Unde...
