This paper shows that this needs not to be always the case. In a context in which two interacting populations have conflicting interests, we introduce ex-ante inequality, by making one population stronger than the other. This reduces the cost of miscoordination for the weakest population, and at the same time it makes some equilibria more equitable than others, thus more focal and attractive for inequality-averse players. Hence, both social preferences and strategic risk considerations may ease coordination. We provide experimental support for this hypothesis, by considering an extended two-population Hawk–Dove game, where ex-ante inequality, number of pure-strategy equilibria, and cost of coordination vary across treatments. We find that subjects coordinate more often on the efficient outcomes in the treatment with ex-ante inequality.\u0000</p>","PeriodicalId":47982,"journal":{"name":"Economic Theory","volume":"19 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model has a unique equilibrium that features randomized pricing strategies, with incumbents always posting higher prices than entrants. For a fixed underlying environment, the equilibrium converges to a stationary equilibrium over time.

To address this question, we develop a probabilistic model of opinion formation and deliberation. Two new jury theorems, one pre-deliberation and one post-deliberation, suggest that deliberation is beneficial.

Formal results and simulations confirm this. But we identify four systematic exceptions where deliberation reduces majority competence, always by increasing Failure 1.

Consider an economy and an allocation chosen by a solution for it. Allowing the replication parameter to vary from agent to agent, we correspondingly adjust the social endowment so that it be possible to assign to each agent and their clone(s) what the agent has been assigned at the allocation under consideration. We require that this list of assignments be chosen by the solution mapping for the resulting economy . We show various ways in which this property is related to other properties that have been discussed in the literature on economic design. We characterize the “Walrasian solution operated from equal division” on the basis of efficiency, the equal-division-lower-bound, and this property, thereby obtaining an analog of the Debreu, Scarf (Int Econ Rev 4:235–246, 1963) convergence theorem in which the no-blocking requirements that define the core are replaced by the equal-division-lower-bound.
