In this paper, we introduce the notion of RAII profiles for asymmetric games with continuous strategy spaces. For these games, we prove that the set of all indirect neutral mutants of a RAII profile is equivalent to a minimal evolutionarily stable set. Furthermore, globally strong uninvadable profiles are shown to be RAII profiles. We also discuss connections between evolutionarily stable sets and strict equilibrium sets of profiles.","PeriodicalId":45451,"journal":{"name":"International Game Theory Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135432013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results showed that, under certain conditions, the system always admits saddle point steady-state equilibrium under independent ventures and R&D cartel games, respectively, and although the process innovation investment under R&D cartel is higher than that under the independent ventures, whether the marginal production cost under R&D cartel is less (higher) than that under the independent ventures depends on the degree of technological R&D spillover and the market competition intensity. Furthermore, the marginal production cost under independent ventures is not monotonically decreasing with spillover for the given region of market competition intensity; while the marginal production cost under R&D cartel game always monotonically decreases with spillover for any market competition intensity.","PeriodicalId":45451,"journal":{"name":"International Game Theory Review","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48041637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
