摘要：This paper presents a non-cooperative evolutionary model to explain the widespread diffusion of lifelong monogamous families. The essential condition, unique to humans, is the overlap of children of different ages. Under this condition, together with the salience of paternal investment and fatherhood uncertainty, monogamy attains a greater survivorship than serial monogamy and polygyny. This result is robust to a number of extensions, including the presence of kin ties, resource inequality, gr...

摘要：In a world in which rational individuals may hold different prior beliefs, a sender can influence the behavior of a receiver by controlling the informativeness of an experiment (public signal). We characterize the set of distributions of posterior beliefs that can be induced by an experiment, and provide necessary and sufficient conditions for a sender to benefit from persuasion. We then provide sufficient conditions for the sender to benefit from persuasion for almost every pair of prior beli...

摘要：No group-strategyproof and ex-post Pareto optimal random matching mechanism treats equals equally. Every mechanism that arises out of the randomization over a set of non-bossy and strategyproof mechanisms is non-bossy. Random serial dictatorship, which arises out of a randomization over all deterministic serial dictatorships is non-bossy but not group-strategyproof. (C) 2016 Elsevier Inc. All rights reserved.

摘要：Standard one- and two-population models for evolutionary games are the limit cases of a uniparametric family combining intra- and intergroup interactions. Our setup interpolates between both extremes with a coupling parameter K. For the example of the hawk dove game, we analyze the replicator dynamics of the coupled model. We confirm the existence of a bifurcation in the dynamics of the system and identify three regions for equilibrium selection, one of which does not appear in common one- and...

摘要：The paper provides a possible explanation for the occurrence of uniform, fixed-proportion rules for sharing surplus in two-sided markets. We study a two-sided matching model with transferable utility where agents are characterized by privately known, multi-dimensional attributes that jointly determine the surplus of each potential partnership. We ask the following question: for what divisions of surplus within matched pairs is it possible to implement the efficient (surplus-maximizing) matchin...

摘要：We employ laboratory methods to study the stability of competitive equilibrium in Scarf's economy (Scarf, 1960). Tatonnement theory predicts that prices are globally unstable for this economy, i.e. unless prices start at the competitive equilibrium they oscillate without converging. Anderson et al. (2004) report that in laboratory double auction markets, prices in the Scarf economy do indeed oscillate with no clear sign of convergence. We replicate their experiments and confirm that tatonnemen...

摘要：Assuming three or more alternatives, there is no systematic rule for aggregating individual preferences that satisfies acyclicity and the standard independence and Pareto axioms, that avoids making some voter a weak dictator, and that is minimally responsive to changes in voter preferences. The latter axiom requires that a preference reversal in the same direction by roughly one third of all voters is sufficient to break social indifference. This result substantially strengthens classical acyc...

摘要：This paper explores a housing market with an existing tenant in each house and where the existing tenants initially rent their houses. The idea is to identify equilibrium prices for the housing market given the prerequisite that a tenant can buy any house on the housing market, including the one that he is currently possessing, or continue renting the house he is currently occupying. The main contribution is the identification of an individually rational, equilibrium selecting, and group non -...

摘要：This paper studies the formation of peer groups entailing the joint production of public goods. In our model agents choose their peers and have to pay a connection cost for each member added to the group. After groups are formed, each agent selects a public project to make a costly contribution to, and all members of the group experience the benefits of these contributions. Since agents differ in how much they value one project relative to the other, the group's preferences affect the generate...

摘要：This paper applies a mechanism design approach to construct a lower bound to the welfare cost of inflation that does not depend on quasi-linear preferences or details of how agents trade. An incentive-feasible trading protocol is derived to minimize the welfare loss subject to frictions rendering money essential. The welfare cost of inflation under this optimal protocol is the lower bound over all pairwise trading protocols of monetary exchange. In general, the first-best is not implementable,...
