We obtain two results: (1) Holding individual i’s wealth and his rank in the wealth distribution constant, the individual’s relative risk aversion decreases when he becomes more relatively deprived as a result of an increase in the average wealth of the individuals who are wealthier than he is. (2) If relative deprivation enters the individual’s utility function approximately linearly then, holding constant individual i’s wealth and the average wealth of the individuals who are wealthier than he is, the individual’s relative risk aversion decreases when he becomes more relatively deprived as a result of a decline in his rank. Our findings provide a theoretical support for evidence about the propensity of relatively deprived individuals to gamble and resort to other risky behaviors.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"44 1","pages":"138 - 146"},"PeriodicalIF":1.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250X.2019.1664508","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43485658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that stable integration is only possible when the minority is small and combined tolerance is large. Unlike the case of the single neighborhood, limiting one population does not necessarily produce stable integration and may destroy it. We conclude that a growing minority can only remain integrated if the majority increases its own tolerance. Our results show that an integrated single neighborhood may not remain so when a connecting neighborhood is created.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"44 1","pages":"221 - 248"},"PeriodicalIF":1.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250x.2019.1695608","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45940993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most work on cohesion in two-mode networks either: (1) attempts to detect cohesion in such networks using one-mode projections (which can be problematic for reasons we discuss); or (2) focuses on restrictive substructures like bi-cliques to identify cohesive subgroups. We propose a new strategy for two-mode networks that follows the general reasoning of approaches to detecting structural cohesion in one-mode networks. Our approach identifies the number of actors from one node set that may be removed before disconnecting actors in the opposite set. We also develop a definition of embeddedness that draws on Moody and White’s hierarchical nesting approach.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"43 1","pages":"179 - 194"},"PeriodicalIF":1.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250X.2019.1606806","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46236107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resolution essentially involves mutual recognition of individuals, thus permitting the phenomena of reputation, reciprocation, and retribution to arise, these being key to stable cooperative societies. The analysis presented, based on evolutionary game theory, serves to emphasize the crucial role of individual recognition by illustrating the consequences of assuming the opposite. It is shown that where tribal membership is apparent, but individuals are not recognizable, evolving mistrust leads to tribal extinction in an evolutionary game theory model. Moreover, a single tribe is also unstable to schism. Subsequently, the extinction of one schismatic group occurs. Failure to recognize individuals therefore facilitates a mechanism which leads to increasing conformity.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"43 1","pages":"195 - 212"},"PeriodicalIF":1.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250X.2019.1602045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48958687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mathematical model was validated in two different countries, Spain and Norway, during the 2007–2015 period. A sensitivity analysis was applied to simulate the future trend (2016–2030), examining the influence of providing public pre-school services (0 to 3 years) on (XISF).

The set of social relations constitute a form of capital that provides the individual with a wide range of resources. Social capital interacts with other forms of capital, particularly with human capital, to enhance inequality. The overlapping-generations model proposed here focuses on the long-term investment processes in human and social capital. When these effects are considered, a society may end up divided into two groups. The first comprises people stuck in a trap of low intergenerational mobility resources. The second group includes people with increasing levels of education and social capital. Within the last group, income inequalities persist due to initial differences in social capital.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"43 1","pages":"23 - 39"},"PeriodicalIF":1.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250X.2018.1470511","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45607870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
