摘要:We study the stable matching problem under the random matching model where the preferences of the doctors and hospitals are sampled uniformly and independently at random. In a balanced market with n doctors and n hospitals, the doctor-proposing deferred-acceptance algorithm gives doctors an expected rank of order logn for their partners and hospitals an expected rank of order n logn for their partners (Pittel, 1989; Wilson, 1972). This situation is reversed in an unbalanced market with n + 1 d...

摘要:We conduct an interactive online experiment framed as an employment contract. Subjects from the US, India, and Africa are matched within and across countries. Employers make a one-period offer to a worker who can either decline or choose a high or low effort. The offer is restricted to be from a variable set of possible contracts. High effort is always efficient. Some observed choices are well predicted by self-interest, but others are better explained by conditional reciprocity or intrinsic m...

摘要:A voting rule is a Condorcet extension if it returns a candidate that beats every other candidate in pairwise majority comparisons whenever one exists. Condorcet extensions have faced criticism due to their susceptibility to variable-electorate paradoxes, especially the reinforcement paradox (Young and Levenglick, 1978) and the no-show paradox (Moulin, 1988b). In this paper, we investigate the susceptibility of Condorcet extensions to these paradoxes for the case of exactly three candidates. F...

摘要:Organized public demonstrations of voter support for policy issues through rallies and petitions are mechanisms by which interest groups sometimes seek to influence political decision-making. We develop a voter-participation model of an interest group's strategic decision to publicly mobilize supportive voters through either a petition with zero participation cost or through a public rally with positive participation cost. Our model shows that voter mobilization can be influential when elected...

摘要:We propose an instrument to measure individuals' social preferences regarding equity and efficiency behind a veil of ignorance while controlling for idiosyncratic risk preferences. We construct a battery of portfolio and wealth distribution choice problems sharing a common budget set. A given bundle induces the same distribution over an individual's wealth in both problems. The portfolio choice solely reflects an individual's risk attitude, providing a benchmark to evaluate whether their wealt...

摘要:We study a class of matching problems in which monetary transfers are possible. In this paper, we establish a close connection between the core and the existence of desirable rules that satisfy strategy-proofness or one-sided strategy-proofness.In our main result, we show that the optimal core is a unified lower bound of welfare for the existence of rules that satisfy strategy-proofness (or one-sided strategy-proofness), efficiency, individual rationality, and no subsidy. Applying this result,...

摘要:The hawk-dove game admits two types of equilibria: an asymmetric pure equilibrium, in which players in one population play hawk and players in the other population play dove, and a symmetric mixed equilibrium, in which hawks are frequently matched against each other. The existing literature shows that when two populations of agents are randomly matched to play the hawk-dove game, then there is convergence to one of the pure equilibria from almost any initial state. By contrast, we show that pl...

摘要:In this paper, we provide an implementation of the optimal mechanism of Es & ouml; and Szentes (2007) for their general environment without assuming constant marginal utility (in the first-stage type) for the buyers. Our implementation is carried out through a three-stage handicap auction. In stage 1, each buyer, knowing his first-stage type, is required to select a handicap menu by paying a menu fee. A higher menu fee would lead to a more favorable handicap menu, which charges a lower handica...

摘要:We study the effect of the option to exit in finite-horizon, two-person bargaining where players make offers alternatingly and incur fixed costs per period. We show that players use take-it-or- leave-it strategies in the unique equilibrium when there is no discounting. Expecting a low payoff at the next period as a respondent, a proposer would choose to exit after her demand were rejected. This causes her opponent to accept her take-it-or-leave-it offer. This prediction is generically valid ev...

摘要:Five classical and uncontroversial axioms-symmetry, weak Pareto optimality, restricted mono- tonicity, midpoint domination, and superadditivity-characterize a bargaining solution. It assigns to each player their midpoint, that is, the -th share of their utopia point, and equally divides what remains.
