     Using a small group experiment, we examine a model of relative deprivation: the effects of a success proportion and a ratio of cost to benefit on investment action and satisfaction. In this experiment, there is a limited numbers of the success. We firstly derive implications and predictions from the model. Secondary, to test the predictions empirically, we collect data from investment games where 18 subjects simultaneously play on z-Tree networks. We find that, on the one hand, the relationship between a success proportion and a choice of the investment action is consistent with the prediction. On the other hand, it is found that the relationship between a proportion of the relatively deprived and that of the success does not fit the prediction. The results suggest that we should develop a model to explain the empirical findings: persons do not inevitably feel deprived when they fail in a small cost investment.

Japanese research on social stratification has paid much attention to class identification which is one of subjective social status. The research field of class identification is an important frontier where theoretical study using mathematical model and empirical research using statistical analysis come across each other. The purpose of this study is to propose a theoretical model of class identification (coordinate-wise order model which is equivalent to the FK model in theory) and to test its empirical validity using vignette survey based on the idea of Karpinski (2009). We prepared stratification profiles (vignettes) based on combinations of three dimensions such as education, occupation, and individual income. We conducted an Internet survey to measure subjective evaluation of stratification profiles. We compared results of statistical analyses to theoretical predictions from the model to test empirical validity of the coordinate-wise order model. The model was not supported enough. We found that income of stratification profile had very strong effect on subjective evaluation of social status. On the other hand, education and occupation had weak effects. These results are different from findings of previous research on class identification. They found that all of education, occupation, and income had moderate effect on class identification. Class identification is evaluation of self-status, however, evaluations of stratification profiles are those of others' status. There is the possibility that different mechanism exist between evaluation of self-status and others' status.

A linear combination model of explanatory variables such as a multiple regression analysis is often used as the simplest approximation of true relation between explanatory and response variable. This paper shows that a linear combination model can be logically derived from the models of mathematical sociology that consist of sociological assumptions and attempts to give a linear combination model theoretical ground. We show that a linear combination model can be an explanatory model rather than just a curve-fitting model. In the context of studies of class identification, we show that the Farao-Kosaka model and the inherited status model can be a theoretical ground for a linear combination model of class identification and clarify the condition that is needed for an integrated development of mathematical sociology and sociometrics in the field of social stratification.

In this paper we formalize the interaction between discriminators and those who are discriminated against, in order to make a theoretical linkage between mathematical sociology and fieldwork studies. We use the imitation dynamics of evolutionary game theory and analyze the change of share of strategies in each group, the discriminators and the victims of discrimination. By the analysis of our model, we obtain the following results. First, discrimination will decrease according to the increase of resistance to it. However, depending on the initial state, there will remain players who still choose a discrimination strategy when t→∞, even though players who are discriminated against prefer resistance to discrimination. Second, the more discrimination exists at the initial state, the more discrimination will have decreased at the end of the dynamics.

     A model of relative deprivation which is formalized by Boudon (1982) and Kosaka (1986) mainly analyzes homogeneous society. Based on the previous research Yamaguchi (1998) and Reyniers (1998) develop a model respectively in order to analyze deprivation in heterogeneous society. In this paper we integrate and generalize their models to explain some empirical findings which appear in the American Soldier. As a result of analysis of our model we derive the following implications. First, the proportion of relatively deprived in an advantaged group, in terms of the cost for investment game, always exceeds that of a disadvantaged group. This proposition is supported by empirical data. Second, there exist domains that the proportion of relatively deprived becomes increasing and decreasing function of proportion of promotion.

     As it is well known, non-cooperative N-person dilemma game has a unique dominant strategy solution where all players choose defecting strategy. In this paper, we analyze an N-person dilemma game by taking the point of view of coalition and try to find the condition that all players choose cooperating strategy in a grand coalition. First, we show that if we transform N-person dilemma game into a coalitional form, then the core is non empty when a characteristic function is defined by the maximin value. We also show the condition that players do not choose cooperating strategy in a grand coalition. Next we specify the condition of existence of core by generalizing a characteristic function. We define a characteristic function by the subjective probability of choosing cooperative strategy. As a result we find that the core is empty when a characteristic function is defined by the maximax value. In general, if players in a coalition believe that other players, who are not members of the coalition, will choose cooperative strategy with a high probability, then the core will be empty by a deviation of a single coalition.

     In this paper we generalize the Breen and Goldthorpe model of relative risk aversion hypothesis that explains the class differentials in educational attainment, in order to specify the condition that an advancement rate of children from service class origin exceeds that of working class origin. By expressing an advancement rate as an explicit function of parameters of a model, we also analyze an inequality of educational attainment by odds ratio that can be expressed as a function of theoretical advancement rate. Our model shows the condition that the odds ratio increases. Moreover, we reformulate a process of succeeding educational transition and analyze a function of theoretical advancement rate. We investigate the condition that the effect of class origin declines across transitions. One of the conditions is that median of distribution of subjective probability of success decrease as education level proceeds. This may reduce advancement rate for service class origin. The other condition is that the advancement rate for working class origin increases as much as that of service class origin when student from working class origin prefer service class to working class. These mechanisms may cause decline of class origin effect.

In general, wellbeing has two distinguishable aspects. There are subjective and objective wellbeing. Subjective well being is a total evaluation on one's life. Objective wellbeing can be divided into physically and socially good conditions. We, as social scientists, are interested in objective wellbeing in the latter sense. Defining health, income and education as indicators of objective wellbeing inevitably includes normative proposition that these resources can make our lives better. Subjective wellbeing and objective wellbeing are inconsistent with each other sometime. However statistical data show a fact that an improvement in objective condition increases subjective wellbeing efficiently in a society with absolute lack of resources. Therefore a society without objective wellbeing should aim to secure resources. On the other hand a society that already achieved certain revel of objective wellbeing should aim to increase subjective wellbeing and reduce discrepancy between subjective and objective wellbeing.

     This paper attempts to formalize the classic theory of a relative deprivation (Stouffer et al. 1949; Merton 1957) by making a theoretical linkage between the justice index (Jasso 1980, 1999) and a model of relative deprivation (Boudon 1982; Kosaka 1986). Our new simple model refers to a mechanism of the determining process of the subjective just reward in which Jasso's arguments were lacking, and specifies the theoretical nature of the justice index by newly defining just reward as an expectation. This enables us to analyze simultaneously two different kinds of concepts, the rate of a relative deprivation and the degree of a relative deprivation. Although the relation between the proportion of a group who feel a relative deprivation and the intensity with which it is felt is not clear in the classic theory, we succeed in revealing the relation by a mathematical model. Furthermore, we specify the property of every justice evaluation function that satisfies the Jasso's condition in a model of relative deprivation.

     What is necessary to claim that mathematical sociology in itself makes theoretical sociology? Referring to development of my earlier paper (Hamada 1999b), the present paper attempts to answer this question. Relying on Fararo(1989)'s idea that a general theory consists of four hierarchical levels, this paper illustrates a comprehensive model into which the “generative model of income distribution” is incorporated as a constituent model. By this, comprehensiveness of a model is emphasized, on the ground that integration of specific models into a more general and comprehensive one gives us a better chances of finding further theoretical ideas and predictions that are not obtainable if we treat with constituent models in isolation.

     R. Boudon and K. Kosaka formalized a matghematical model of relative deprivation. The implication derived from the Boudon-Kosaka model (Kosaka 1986) is that proportion of the relatively deprived increases up to a critical point, then decreases as prize density increases. As the marginal rate of return increases, the possible maximum proportiion of the relatively deprived also increases. However, in so far as assumptions with regard to reference group, a model seems to take no account of findings of pre-existing empirical studies, such as Merton (1957), and Stouffer et al. (1949a).<BR>     The present paper attempts to modify the Boudon-Kosaka model and integrate concepts of relative deprivatiion and reference group theoretically. The modified model will show that, under condition in which players choose reference group based on certain principle of common attribution, the possible maximum values of proportion of the relatively deprived are constant despite changes in the marginal rate of return, R, and a single critical point becomes double where R&rsaquo;1.

     The purpose of this paper is to formalize a simple model that theoretically connects individuals' rational choice at micro level to income distribution, which is according to the Gibrat's law empirically, as social structure at macro level. We employ iterative investment game as a baseline model in which player has a binary choice between investing and not investing. Given parameters which prescribe payoff structure of the game are the prize density γ and the rate of return R . Method of analysis is a simulation with computation.<BR>     We investigated changes in Gini coefficient and skewness of the gross profit distribution, as the parameters varied as follows : 0≦γ≦1, R={0.5,1,2,3}, and n (the number of times that the game is repeated) = 5 or 10. As a result of analysis, we derived the implication that Gini coefficient increases up to critical point, where γ≦1/(R+1), then decreases as prize density increases, where γ>1/(R+1).<BR>     Furthermore, we show that our model, with cumulative effect, generates a lognormal distribution under condition that γ>1/(R+1).

In sociology, many studies have pointed out that the combination of marriage with love had not been established until the modern era. The purpose of this paper focusing solely on Japan is to clarify the essence of the transformation of love that is conjectured from the fact that the Japanese word "ren-ai" means approximately the same thing as the English "love" or the French word amour. Furthermore, ren-ai has been prominent use in Japan since the Meiji period. Through an analysis of 'love, ' I want to provide and to show the grounds for an argument that understanding historical change in a specific mode of communication is one way to make clear endemic elements of "modernity.

代表者の浜田は，準拠集団理論の統一的な数理モデルを提案するために，Yitzhakiによる相対的剥奪指数（realtive deprivation index）と，浜田によるδ近傍モデルが一致する数学的条件を特定した．また両モデルの統合から，準拠集団の選択範囲を制限した不完全相対的剥奪度／満足度を定式化し，理論モデルから高層よりも下の所得階層では，準拠集団の選択範囲が広いほど，不完全相対的剥奪度は大きくなる．準拠集団の選択範囲の違いによる剥奪度への影響は，客観的所得階層が高くなるほど弱くなり，やがて消失する等のインプリケーションを導出した．分担者の石田は所得評価の他者比較モデルの分析に取り組んだ．客観分布ではなくバイアスのある主観的分布からの他者のサンプリングによって評価が形成されるメカニズムを一般的に表現するモデルを考案し，経験的データから主観的分布を推定する枠組みを構築した．2015SSPデータを用いた分析から，男性よりも女性の方があいまいな主観的分布を持つこと，男性の中でも45-54歳の年齢階層がもっとも客観分布に近い主観的分布を持つことが明らかになった．分担者の清水は、社会的価値志向性をベイズモデリングによって測定・推定するための新しい枠組みを提供した。シミュレーション研究の結果から、これまでの社会的価値志向性その測定には一定のバイアスが生じうること、提案手法ではそのバイアスが生じないことが明らかとなった。また再テスト信頼性の結果、これまでの方法と同程度あるいはそれ以上の信頼性があることがわかった。さらに、実際に経済ゲーム実験を行った結果、理論的な予測に一致する結果が見られ、予測的妥当性も優れていることが明らかとなった。

The purpose of this research project was to approach social change theory by the method and technique of computational social science, and to shift from trend theories to a new social change theory focusing on the mechanism of social change. For this purpose, on the one hand, we theoretically considered the connection between computational social science and social change theory, and on the other hand, we conducted empirical analyses of social change using Twitter data and other data. Regarding agent-based modeling of social change, we laid a theoretical foundation for understanding the meaning hidden in social change with reference to Goldberg and Stein (2018) and others.

Social exclusion has been addressed primarily through case studies or social surveys. Although they have reported important findings, it has been difficult to analyze the general dynamic process of social exclusion. Therefore, this research project aimed to elucidate the dynamic process of social exclusion using computational social science and to propose measures to deter social exclusion based on the findings. As a result, we found that an analysis using big data such as Twitter data and a simulation combining Schelling's residential segregation model and the dynamic fluctuation of land prices can grasp the dynamic process of social exclusion. In the future, we will examine the possibility of making policy recommendations based on the findings obtained.

SSP2015, Stratification and Social Psychology Survey in 2015, is a nation-wide survey carried out by us. The project named SSP consists of the members and the collaborators of this grant-aid research. We prepared the data properly at first, then we shared them within the project. After we held research meetings based on data analyses, we provided the outcome to public. We held symposiums and an international workshop. Also, we made presentations in academic meetings. We presented more than 50 of academic papers based on these work. All in all, we pursued to make wide outreach of the survey research data. These efforts promote people’s understanding of contemporary Japanese society.

The concept of social exclusion captures the process in which exclusion from a social sphere leads to that from another sphere. For example, poverty, exclusion from economic life, is likely to lead to social isolation, exclusion from social life. This project studied this accumulative process using agent-based models that create artificial society on computer and big data analysis of discourses on the Internet. A main finding is that two factors contribute to the emergence of the accumulative process: Weak linkages between social institutions in various social spheres and polarization of discourses.

In this study, we have longitudinally examined accumulated social survey data from Japan since 1980s. In addition, we pursued five preliminary social surveys and experiments, so that we could grasp the current socio-economic reality, which was called mass-inequality society. At the same time, we developed a CAPI (computer assisited personal interviewing) social survey method and introduce it to the 1st Stratification and Social Psychology survey in 2015, which is one of the latest nationwide social surveys. We are currently in the process of detailed analysis, though we have immediately reported the descriptive outcome of the survey.

We conducted an internet survey for empirical analysis of reference group and relative deprivation, and found a significant relationship between the comparison mechanism and subjective well-being. We also conducted a questionnaire survey in Nepal as an empirical research of relative deprivation in developing countries, and found marked difference in degree of deprivation according to caste class. As for theoretical study of the mechanism of relative deprivation, we proved the theoretical existence of a paradox that people's feeling of relative deprivation can be enhanced by a certain kind of economic growth. Besides, we improved models of relative deprivation. As for study of relative deprivation indices, we proposed a method to decompose the societal average of relative deprivation as well as the Gini index of inequality according to whether it is caused by inequality of opportunity or not.

We examined the effects of economy and policy of local government which create disparity among regions, upon disparity among individuals. In the main survey, we examined the effects by looking atthe relation between the cities’/villages’ health policy and the difference of health among individuals. As a result, participation in hobby and entertainment activities encourages people to take health services. Participation in local regional activities also encourages them to do so, but the effect is larger in cities/villages with weaker financial capability.

Our study attempt to formalize a generating process of inequality, such as, differentials in educational attainment among class origin and test empirical validity of the model. We succeed to generalize a process of class identification and show that a distribution of class identification asymptotically obeys normal distribution under more general conditions that that of previous studies.

The purpose of this project is to analyze the effect of redistribution of wealth at global level on people's subjective well-being (SWB) and subjective ill-being (SIB) by constructing a simulation model. The results of simulation analysis based on the World Values Survey dataset reveals that transfer of wealth from developed countries to underdeveloped countries enhances SWB and diminishes SIB in the world, and effect on diminution of SIB is much greater than enhancement of SWB.

今年度は新たに,大学進学率と世代間移動の単純ではない関係を,数理モデルによって定式化する研究を進めた.先行研究としてブードンのISO (Inequality of Social Opportunity)モデル,すなわち「社会的機会の不平等(世代間移動の不平等)」に焦点を当てたシミュレーションが「教育機会の平等化は必ずしも社会移動の不平等度を減少させるわけではない」という分析結果を導出している.ただしその命題はあくまでシミュレーションに基づいた特殊な計算事例である.そこで本研究では,特定の数値に依存しない一般的な命題を導くために,モデルが2次元(学歴と出身階層)2ランク(高と低)の社会からなり,学歴が高い者が優先的に上層に参入できるという単純な仮定を採用した.より厳密には二つの選抜形式をモデル化して分析する.一つは辞書体式順序によって出身階層の影響も考慮する場合と,もう一つは完全に学歴のみを選抜基準とする場合である.前者の仮定を用いたモデルを辞書体式順序モデル,後者の仮定を用いたモデルを学歴主義モデルと呼ぶ.二つのモデルを比較分析することで,教育機会の拡大が世代間上昇移動の閉鎖化を生み出すというパラドキシカルな現象がどのような条件のもとで発生するのかを特定した.またモデルは教育機会の均等化と世代間上昇移動の関係も明らかにした.さらにモデルから理論的な命題を導出するだけではなく,モデルが現実のデータにどの程度フィットしているのかを全国調査データを用いて検証した.この研究成果は既に論文としてまとめ,現在レフェリー付き学会誌に投稿中である.
