摘要：We address the issue of bidder ring formation in single and multi-unit Vickrey auctions. We analyze this issue in a bargaining game set up under the assumption that valuation of bidders is commonly known only amongst themselves. In the single unit case, we show that the equilibrium coalition structure can only be an order preserving r-ring, that includes the winner and the top (r - 1) losers. In the multiple units case, we specify sufficient conditions for formation of an interesting class of ...

摘要：This paper addresses the question of existence of stationary Markov perfect equilibria in a class of dynamic games that includes many known bargaining models and models of coalition formation. General sufficient conditions for existence of equilibria are currently lacking in a number of interesting environments, e.g., models with non-convexities, consumption lower bounds, or an evolving state variable. The main result establishes existence of equilibrium under compactness and continuity condit...

摘要：This paper considers the incentive compatibility in many-to-many two-sided matching problems. We first show that the Blocking Lemma holds for many-to-many matchings under the extended max-min preference criterion and quota-saturability condition. This result extends the Blocking Lemma for one-to-one matching and for many-to-one matching to many-to-many matching problem. It is then shown that the deferred acceptance mechanism is strategy-proof for agents on the proposing side under the extended...

摘要：The operation of the posted offer market with advance production environment (Mestelman and Welland, 1988), appropriately parameterized, differs from that of the market entry game (Selten and Guth, 1982), appropriately presented, only in terms of price-setting. We establish the effect of this difference in price-setting on attainment of the competitive equilibrium allocation while controlling for effects relating to the presentation of the market entry game and to the stationarity or non-stati...

摘要：False inference may be drawn in asymmetric information environments where the type space is multi-dimensional and the analysis is restricted to only one of those dimensions. We demonstrate this by studying donation-visibility in a charitable-giving environment. Past studies show that donation-visibility increases giving and argue that this is consistent with donations signaling generosity or income and thereby improving donors' status. However, this explanation relies on status being one-dimen...

摘要：Motivated by the literature on random choice and in particular the random utility models, we extend the analysis in Bossert and Sprumont (2013) to include the possibility that players exhibit stochastic preferences over alternatives. We prove that every random choice rule is backwards-induction rationalizable. (C) 2017 Elsevier Inc. All rights reserved.

摘要：This paper experimentally explores how compositional grammars in artificial codes emerge and are sustained. In a communication game with no conflict of interest, the sender sends a message that is an arbitrary string from available symbols with no, prior meaning to indicate an abstract geometrical figure to the receiver. We find strong evidence from the laboratory for the emergence of compositional grammars in the subjects' common codes that facilitate learning efficiency. Moreover, when there...

摘要：Individuals adopt diverse measures to prevent contagion during interactions. I propose a model to study the implications of the protection technology on the prevalence of infections and on welfare at different levels of exposure. I find that the effect of aggregate exposure on prevalence and on protection inefficiencies depends crucially on the characteristics of the available protection technology. For example, a vaccine may yield lower infection rates and smaller costs of decentralization as...

摘要：This paper presents a model of strategic network formation with local complementarities in effort levels and positive local externalities. Results are obtained for a general class of payoff functions, which subsumes the linear-quadratic specification frequently used in theoretical and applied work. We assume homogeneous agents and characterize equilibria for two-sided and one-sided link formation. (Pairwise) Nash equilibrium networks are nested split graphs, which are a strict subset of core-p...

摘要：Online auctions with a fixed end-time often experience a sharp increase in bidding towards the end (sniping) despite using a proxy-bidding format. We provide a novel explanation of this phenomenon under private values. We show that it is closely related to shill bidding by the seller. Late-bidding by buyers arises not to snipe each other, but to snipe the shill bids. We allow the number of bidders in the auction to be random and model a continuous bid arrival process. We show the existence of ...
