The core assumption is that individuals have productive potentials, e.g., innovations, that can not be put at use autonomously. However, individuals can associate in a club to match productive innovator-implementor dyads among the members. For a given club, allowing one new member has the effect of a) an increased pool of innovations and b) an increased pool of potential implementers. Whether a particular member supports the expansion of the club depends on whether she expects to be an implementor or an innovator. When expansion of membership is decided by vote, both small exclusive clubs and open clubs encompassing the whole society can emerge. The outcome depends both on the voting protocol, on the distribution of innovator and implementer skills, and on the maximal potential club size. Moreover, identical environments may generate multiple equilibrium club sizes. In which of these the society ends up depends on the initial conditions and on the voting protocol.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"47 1","pages":"255 - 282"},"PeriodicalIF":1.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47892273","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}

Based on the life cycle model of collective actions, the man–land relationship governs the rise and fall cycles, namely dynastic cycles. We combine agent-based modeling, systemic dynamics, and numerical simulations, to build the life cycle model of empires. It aims to investigate the rise and fall process of 18 major dynasties (empires) in history of China, from BC 221 to AD 1912. The core aim is to find optimal solutions, which achieve the best matching between simulations and real history. According to our algorithm, the optimal solutions can be obtained, when we have the minimal span differences (gaps) between simulated and real empires. First, we traverse all related parameters, and select simulations with 18 empires. Second, we select the cases with the total ticks between 2122 and 2132 years (ticks). Third, we select cases whose differences (gaps) are within 20 years. Finally, we obtain three optimal solutions (combinations of parameters) whose validity (100 simulations) and robustness (1000 simulations) have been checked. It seems that our life cycle model has achieved the best fitness to real empires in the history of China. For distributive matching of durations (spans), both discrete and continuous forms can be matched. Besides, the simulate and real durations can be matched as well, under counterfactual inferences of 16–17, 18 & 19–20 pairs. Based on our model, the whole history process of China can be back-calculated. Therefore, it seems that the trend of human history (society) may be an automatic process, which cannot be altered by man’s will.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"47 1","pages":"170 - 206"},"PeriodicalIF":1.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46181589","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}

In this study, we generalize Fermi-Dirac distribution by using a q,p-deformed version of Fermi-Dirac distribution which provides the advantage of working with flexible free q, p deformation parameters as the regression parameters for modeling the income data. We analyze the accuracy of the generalized version, q,p-deformed Fermi-Dirac distribution, on describing the data of income share held by quintiles for countries, and household income for the states of U.S.A. in 2018. We also use minimization routine for modeling the data which leads to the best fit parameters for the deformation parameters q and p. Subsequently, we plot the fitted q,p-deformed Fermi-Dirac distribution as income distribution with the obtained deformation parameters, then find the statistical confidence values from the fitted curve. We figure out that our model properly describes the income data for the systems experiencing a high level of income inequality, and also values are correlated with the Gini index for those of considered systems.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"47 1","pages":"97 - 122"},"PeriodicalIF":1.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49103316","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 neutral model of cultural evolution, which assumes that taste is transmitted via an unbiased copying process, provides precise predictions regarding expected popularity distributions and turnover within a popularity-ranked list. Recent advances in this line make it possible to characterize the likelihood of music taste transmission mechanisms by investigating departures of observed turnover rates from neutral model predictions. Here, I bias the neutral model to investigate four alternative conceptions of individual music taste transmission (song quality, individual status, social network, and anticonformist) and use agent-based simulations to examine the impact on turnover. I then compare modeled with empirical turnover data from the Billboard Hot 100 over the period from 1958 to 2021 and find that observed turnover patterns are reproduced only in an anticonformist model simulating the systematic rejection of the most popular songs. This finding was unexpected and challenges the notion of a generalized “preference for the popular.” Overall, this study contributes to ongoing debates regarding the mechanisms involved in the transmission of taste and the mechanics of fashion change.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"47 1","pages":"42 - 74"},"PeriodicalIF":1.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/0022250X.2021.1956918","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43153590","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}

It is observed from empirical survey data that income evaluation is concentrated in the middle. We develop a model that assumes income comparison on a subjective income reference distribution to explain the centralization phenomenon of income evaluation. We conduct theoretical analysis and empirical parameter estimation using Bayesian statistical modeling. The theoretical analysis shows that the centralization of income evaluation distribution occurs when the subjective reference distribution is more dispersed than the objective distribution. Empirical analysis using Japanese data from 2015 shows that the relationship between subjective and objective distributions differed depending on social categories with different social experiences. Women had a more ambiguous distribution than men. Among men, those aged 45–54 had a subjective distribution closest to the objective distribution. Thus, the subjective reference income distributions that potentially define people’s evaluation of their income and their differences based on social category were only clarified by constructing the model.","PeriodicalId":50139,"journal":{"name":"Journal of Mathematical Sociology","volume":"47 1","pages":"75 - 96"},"PeriodicalIF":1.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45150422","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}
