摘要：We consider sampling best response decision protocols with statistical inference in population games. Under these protocols, a revising agent observes the actions of k randomly sampled players in a population, estimates from the sample a probability distribution for the state of the population (using some inference method), and chooses a best response to the estimated distribution. We formulate deterministic approximation dynamics for these protocols. If the inference method is unbiased, stric...

摘要：A monopoly seller is privately and imperfectly informed about the buyer's value of the product. A designer can provide the seller with additional information, which the seller uses to price discriminate the buyer. We demonstrate the difficulty of screening the seller's information: When the buyer's value is binary, no combination of buyer surplus and seller profit can be implemented other than those achieved by providing the same information to all seller types. We use the result to characteri...

摘要：This paper studies general two-player sequential-move competitions, accommodating a full spectrum of Tullock contest technology and contestants' asymmetry. We provide necessary and sufficient conditions for a preemptive equilibrium to prevail in both strong-lead and weak-lead contests, and discover a characteristic equation to pin down the players' effort ratio (which fully determines their winning chances) and their effort levels when a non-preemptive equilibrium prevails. We find that while ...

摘要：We investigate the convergence properties of an adaptive learning model that overlaps those of stochastic fictitious play learning and experience-weighted attraction learning in normal form games with strict Nash equilibria. In particular, we consider the case in which adaptive players play a game against not only other adaptive players but also committed players, who do not revise their behaviour but follow a fixed (strict Nash equilibrium or corresponding logit quantal response equilibrium) ...

摘要：We study dynamic mechanism design in non-clairvoyant environments, where sellers cannot forecast future demand and buyers hold private information. Using two laboratory experiments, we evaluate two non-clairvoyant mechanisms: the dynamic maximin-optimal non-clairvoyant mechanism (DM, Mirrokni et al., 2020) and the repeated static optimal mechanism (RS, Myerson, 1981). Experiment 1 compares DM and RS between demand-distribution scenarios and shows that non-clairvoyant mechanisms perform as inte...

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：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：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：Networks frequently experience attrition as individual members exit over time. Such departures can significantly impact the behavior of their peers and have cascading effects on overall network activity. We investigate such effects within the framework of the canonical linear-quadratic model of peer influence. We introduce an exogenous shock that removes certain agents from the network, with the key feature that only their immediate neighbors observe these departures. In this setting of incomp...
