The model is presented in the context of aggregating preferences over intertemporal streams of social outcomes, in which Zuber and Jackson and Yariv have shown the impossibility of a time-consistent and Paretian social objective function. Unlike previous studies, our investigation focuses on the compatibility of the Pareto condition with the impure social planner who has a dynamically consistent self-control utility function characterized by Gul and Pesendorfer. Assuming that the social planner is tempted to adopt the majority's opinion when there is a conflict of opinions among individuals, the paper characterizes an aggregation form in which the planner is allowed to depart from dictatorship in ex-post choice under noncommitment.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"26 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpet.12674","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138519653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vaccine markets often suffer from three imperfections: high concentration, network effects, and a health externality (contagion). The first conclusion of the paper is that the negative network externality is important as a market distortion, as it may lead to significant welfare losses. The second and main part of the paper develops a two-part per-unit subsidy scheme that a social planner could use to target both consumers and producers of vaccines. The scope of such a subsidy scheme to induce the firms to produce the first-best output without network effects (which is the most ambitious first-best target) is investigated. In many cases, while the first-best is attainable, it requires negative prices for vaccines, which amounts to rewarding consumers to induce them to vaccinate.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"25 6","pages":"1229-1250"},"PeriodicalIF":1.1,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134957221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Before the vote sender commits to a signal which sends private, potentially correlated, messages to receivers that are contingent on the true state of the world.

We therefore focus on the equilibrium where receivers vote sincerely, that is they vote in favor of the outcome that is optimal given their posterior. We characterize the optimal public and the optimal private signal, both for the case where receivers are behavioral and vote sincerely as well as the case where such behavior is a Bayes–Nash equilibrium (BNE). For the optimal public signal, sincere voting is a BNE, but the optimal private signal is subject to the swing voter's curse.

Recent recovery plans, associated with the COVID-19 pandemic and the energy transition, increased the funding available to finance innovative low-carbon projects and called for an economic evaluation of their allocation. This paper analyzes the potential benefit of using repayable advance: a lump-sum payment to finance the project that is paid back in case of success. The relationship between the state and innovative firms is formalized in the principal-agent framework. Investing in an innovative project requires an initial observable capital outlay. We introduce asymmetric information on the probability of success, which is known to the firm but not to the state agency. The outcome of the project, if successful, delivers a private benefit to the firm and an external social benefit to the state. In this context a repayable advance consists in rewarding failure. We prove that it is a superior strategy in the presence of pure adverse selection. We investigate under what conditions this result could be extended in the presence of moral hazard.
