Three players, one of whom is permanently endowed with veto power, must split a fixed budget in each period. Despite her additional power, the veto player cannot always asymptotically extract the full surplus. The non-veto players endogenously prevent each other's expropriation when they are patient and have high initial allocations in the unique stationary, symmetric, stage-undominated, coalition-proof Markov perfect equilibrium. Further, we show that veto power and higher recognition probability may be strategic substitutes rather than complements. We also provide an intuition behind selfish egalitarianism between non-veto players. Our technique of employing coalition-proofness and iteratively generating a new equilibrium with novel predictions sheds light on the divergence in recent literature on the value of veto power and may be useful in other environments.</div></div>","PeriodicalId":48291,"journal":{"name":"Games and Economic Behavior","volume":"152 ","pages":"Pages 345-370"},"PeriodicalIF":1.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144069878","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}

For two alternatives and an odd number of agents, it follows from May's Theorem that the majority aggregation rule is the only one satisfying anonymity, neutrality and strategy-proofness (SP). For more than two alternatives, anonymity and neutrality are incompatible for many problem instances and we explore this tradeoff for strategy-proof rules. The notion of SP that we employ is Kemeny-SP (K-SP), which is based on the Kemeny distance between social orderings and strengthens previously used concepts in an intuitive manner. Dropping anonymity and keeping neutrality, we identify and analyze the first known nontrivial family of K-SP rules, namely semi-dictator rules. For two agents, semi-dictator rules are characterized by strong unanimity, neutrality and K-SP. For an arbitrary number of agents, we generalize semi-dictator rules to allow for committees and show that they retain their desirable properties. Dropping neutrality and keeping anonymity, we establish possibility results for three alternatives. We provide a computer-aided solution to the existence of a strongly unanimous, anonymous and K-SP rule for two agents and four alternatives. Finally, we show that there is no K-SP and anonymous rule which always chooses one of the agents' preferences.</div></div>","PeriodicalId":48291,"journal":{"name":"Games and Economic Behavior","volume":"152 ","pages":"Pages 216-240"},"PeriodicalIF":1.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922739","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}

In this study, we examine conditional cooperation under uncertainty. Using a novel experimental design, we exogenously manipulate the likelihood that a subject's partner in a Prisoner's Dilemma will cooperate. Information about the partner's cooperation is either presented descriptively or learned through experiential sampling. We observe a description-experience gap: subjects are more likely to cooperate under experience than under description when their partner's probability of cooperation is low, while the opposite holds when it is 50% or higher. This result contrasts with expectations deriving from the individual choice literature, where rare events are typically underweighted in experience-based decisions. We find that the gap we observe is driven by conditional cooperators being less responsive to social information acquired experientially than to that acquired descriptively. Furthermore, we show that stronger priors held by subjects under social uncertainty compared to individual uncertainty can account for the disparity with the individual choice literature.</div></div>","PeriodicalId":48291,"journal":{"name":"Games and Economic Behavior","volume":"152 ","pages":"Pages 241-256"},"PeriodicalIF":1.0,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922740","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}
