摘要：We identify a condition on preference domains that ensures that every locally strategy-proof and unanimous random social choice function is also strategy-proof. Furthermore every unanimous, locally strategy-proof deterministic social choice function is also group strategy-proof. The condition identified is significantly weaker than the characterization condition for local-global equivalence without unanimity in Kumar et al. (2020). The condition is not necessary for equivalence with unanimous ...

摘要：We examine the prevalence of gradualist strategies and their effect on trust-building and economic gains in a setting with an infinite horizon, asymmetric information regarding the trustworthiness of receivers, and various levels of trust. The theoretical literature suggests that gradualist strategies mitigate asymmetric information problems and foster trust-building. However, we theoretically and experimentally show that gradualism sometimes reduces joint payoffs relative to a simple binary s...

摘要：A large polarized electorate decides repeatedly between a reversible alternative (REMAIN) and an irreversible alternative (LEAVE) in an environment where the aggregate short-term effects of the decision vary from period to period. Decisions by simple majority or by a too low supermajority may perform poorly under circumstances where it is socially optimal to never LEAVE, as they can exhibit equilibria where LEAVE is chosen quickly. In general, a too low supermajority rule can have much higher ...

摘要：We analyze nonlinear pricing with finite information. We consider a multi-product environment where each buyer has preferences over a d-dimensional variety of goods. The seller is limited to offering a finite number n of d-dimensional choices. The limited menu reflects a finite communication capacity between the buyer and seller. We identify necessary conditions that the optimal finite menu must satisfy, for either the socially efficient or the revenue-maximizing mechanism. These conditions re...

摘要：Many decisions taken in legislatures or committees are subject to lobbying efforts. A seminal contribution to the literature on vote-buying is the legislative-lobbying model pioneered by Groseclose and Snyder (1996), which predicts that lobbies will optimally form supermajorities in many cases. Providing the first empirical assessment of this prominent model, we test its central predictions in the laboratory. While the model assumes sequential moves, we relax this assumption in additional trea...

摘要：We study the problem of stochastic stability for evolutionary dynamics under the logit choice rule. We consider general classes of coordination games, symmetric or asymmetric, with an arbitrary number of strategies, which satisfies the marginal bandwagon property (i.e., there is positive feedback to coordinate). Our main result is that the most likely evolutionary escape paths from a status quo convention consist of a series of identical mistakes. As an application of our result, we show that ...

摘要：This paper studies a multi-state binary choice experiment in which in each state, one alternative has well understood consequences whereas the other alternative has unknown consequences. Subjects repeatedly receive feedback from past choices about the consequences of unfamiliar alternatives but this feedback is aggregated over states. Varying the payoffs attached to the various alternatives in various states allows us to test whether unfamiliar alternatives are discounted and whether subjects'...

摘要：Neoclassical economic theory assumes that whenever agents tackle dynamic decisions under ambiguity, preferences are represented by the Subjective Expected Utility (SEU) model and prior beliefs are updated according to Bayes rule, upon the arrival of partial information. Nevertheless, when one considers non-neutral ambiguity attitudes, either the axiom of dynamic consistency or of consequentialism should be relaxed. Using data from an economic experiment on dynamic choice under ambiguity, we st...

摘要：This paper presents a model of elections that explores the relationship between incumbent upsets and incumbents running unopposed. A valence-disadvantaged candidate (a potential challenger), who possesses private information about the extent of this disadvantage, first decides whether to challenge a valence-advantaged candidate (the incumbent). If the election is contested, the two candidates engage in policy competition. In equilibrium, the incumbent is never certain of the strength of a chal...

摘要：We present a model of truthful elicitation which generalizes and extends mechanisms, scoring rules, and a number of related settings that do not qualify as one or the other. Our main result is a characterization theorem, yielding characterizations for all of these settings. This includes a new characterization of scoring rules for non-convex sets of distributions. We combine the characterization theorem with duality to give a simple construction to convert between scoring rules and randomized ...
