In this paper, we provide a direct proof of the above result using Kakutani's fixed-point theorem when the sizes of coalitions are not only finite but also bounded above. This condition simplifies the presentation of the model and the existence proof. Unlike previous work, we dispense with the comprehensiveness assumption in NTU games, thereby broadening the applicability of our result to include matching problems and hedonic coalition formation models. Furthermore, we show that, in the absence of comprehensiveness, <i>f</i>-core allocations may fail to exhibit equal treatment in payoffs for the same type of players. We also note that Scarf's nonemptiness result for the core of NTU games follows as a corollary of our main theorem.</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"27 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316787","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}

The rise in the skill premium encourages higher education enrollment. When higher education is costly for individuals or their families, a rising skill premium (i) improves the relative position of children from skilled families, (ii) reduces interskill intergenerational mobility, and (iii) fosters inequality across skilled workers (“intraskilled inequality”). The impact depends on education funding, and the only situation in which skilled families are not favored is when higher education is freely provided. In this case, the increase in university enrollment must come with an increase in public expenditure on higher education to prevent the deletion of the highest skills. These results are in line with the developments observed in the last four decades in advanced economies, where the constant increase in the skill premium has come with a general increase in the educational level of the population, which has been higher at the top of the skill ladder.</p>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"27 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpet.70070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272004","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}

Two teams of two players compete in a Tullock contest with teammates' sequential efforts aggregated across two periods using a Cobb–Douglas production function. We examine how equilibrium efforts and winning probabilities are affected by the teams' communication policies: no communication, private communication (efforts shared internally with stage-2 teammates), and public communication (efforts disclosed to stage-2 rivals as well). To describe asymmetric information generated by privately observable efforts for each communication policy profile, we use a perfect Bayesian equilibrium with an appropriate belief refinement for multistage complete information games. In the unique positive-effort equilibrium, the optimal choice of a communication strategy differs for the favorite (the strong team) and the underdog (the weak team). Private communication only benefits the underdog team, fostering effort complementarity and improving their chances of winning and payoffs. In contrast, the favorite team prefers either public or no communication to deter rival efforts or avoid intrateam free-riding. Importantly, endogenous communication policies reshape competitive dynamics, with private disclosure of efforts serving as a strategic equalizer for weaker teams.</p>\u0000 </div>","PeriodicalId":47024,"journal":{"name":"Journal of Public Economic Theory","volume":"27 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224456","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}
