Do the Privileged Always Win? Economic Consequences of Divorce by Income and Gender Groups

Social Indicators Research - The heterogeneous economic results of divorce have received limited attention. The current study analyzes such consequences from an intersectionality perspective, where...     

Lagrange multiplier unit root test in the presence of a break in the innovation variance

We show that the Lagrange multiplier (LM) unit root test exhibits size distortions when a break in the innovation variance exists but is ignored. We develop a modified LM unit root test that is based on a generalized least-squares transformation of the original series. The asymptotic null distribution of the new modified LM unit root test is derived. Finite-sample simulation evidence shows that the modified LM unit root test maintains its size and has reasonable power against the trend stationary alternative.     

Israeli and Polish Policies toward Returning Residents as a Reflection of Nationhood

This study focuses on Poland and Israel, both commonly classified as ethnic nation-states, and aims to question the expression of ethnic–civic dichotomy in return-migration policies. Policy documents in each country were analysed and complemented by interviews with policymakers and representatives from relevant organizations. Our analysis reveals that, although there are differences in their policies toward returning residents and in the related programmes in both countries, Israeli and Polish policies include both ethnic and civic components. Therefore, our study supports Joppke's (2005) argument that there is no purely civic or ethnic nationalism and there can be no purely civic or ethnic nation. We show that the proportion of ethnic and civic elements may change over time; thus, our findings contribute to the growing literature pointing to the dynamic nature of nationalism.     

Family Involvement and Holocaust Salience among Offspring and Grandchildren of Holocaust Survivors

The present research focuses on family involvement reported by offspring and grandchildren of Holocaust survivors (OHS and GHS, respectively). Study 1 included a convenience sample of 75 participants, divided into 2 groups (36 OHS and 39 comparisons). Study 2 included a convenience sample of 92 dyads of OHS and GHS. Both samples completed the Family Involvement Questionnaire and the Holocaust Salience Scale. In line with the hypotheses, Study 1 found that, relative to comparisons, OHS presented greater familial involvement. Only OHS with strong family involvement showed higher Holocaust salience than comparisons. Study 2 showed higher familial involvement among OHS as compared to GHS, and significant parent-child correlations. The results show that family involvement is related to intergenerational transmission of the trauma, especially among OHS. Yet, among OHS and GHS, parents’ and children’s family involvement were associated. The theoretical and practical implications of these findings are discussed.     

Application of the characterization theory to the mixture model

This paper indicates the potential application of the characterization theory to the mixture model. It discusses a particular example of a mixture model and concludes that successful application of this theory can be made in order to choose the appropriate mixture model and the mixing parameter.     

The psychosocial consequences of an environmental disaster: Selected case studies of the Bhopal gas tragedy

The present study deals with the psychosocial problems which the Bhopal gas victims are facing. These problems were examined through selected case studies, which reveal that there have been changes in the intrafamilial relationships in the area. There are households where the social status of the women has gone up as they have become the earning members of the family, while on the other hand some women are being ill treated as they are unable to conceive and bear children.     

Connected Substitutes and Invertibility of Demand

We consider the invertibility (injectivity) of a nonparametric nonseparable demand system. Invertibility of demand is important in several contexts, including identification of demand, estimation of demand, testing of revealed preference, and economic theory exploiting existence of an inverse demand function or (in an exchange economy) uniqueness of Walrasian equilibrium prices. We introduce the notion of “connected substitutes” and show that this structure is sufficient for invertibility. The connected substitutes conditions require weak substitution between all goods and sufficient strict substitution to necessitate treating them in a single demand system. The connected substitutes conditions have transparent economic interpretation, are easily checked, and are satisfied in many standard models. They need only hold under some transformation of demand and can accommodate many models in which goods are complements. They allow one to show invertibility without strict gross substitutes, functional form restrictions, smoothness assumptions, or strong domain restrictions. When the restriction to weak substitutes is maintained, our sufficient conditions are also “nearly necessary” for even local invertibility.     

Attachment and leader's development via experiences

Apart from biographies and memoirs of outstanding leaders, studies on the development of leaders in everyday life from childhood to maturity are rare. We propose a developmental model of leaders in which certain variables formed in early childhood are the basic components for leadership development in later life. These are a low level of trait anxiety [Spielberger, C.D. (1972). Conceptual and methodological issues in anxiety research. In C.D. Spielberger (Ed.), Anxiety: Current trends in theory and research. New York: Academic Press, vol. 1] and openness to experiences [Costa, P.T. Jr., & McCrae, R.R. (1992a). Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) professional manual. Odessa, FL: Psychological Assessment Resources]. We argue that secure attachment style [Bowlby, J. (1969). Attachment and loss: Vol. 1. Attachment. New York: Basic Books] explains the formation and influence of these basic components, which in turn affect the leader's development through experience in leadership roles. Questionnaires were administered to 286 subjects. The data obtained were analyzed by structural equation modeling (SEM).The findings show that trait anxiety and openness to experience affect leaders' development via experiences. Alternative models in which formative variables may affect the magnitude and intensity of leadership experiences are discussed.     

绿色新政：欧洲走出危机的长期性、可持续计划

欧洲绿党所倡导的“绿色新政”,其目的在于实现在地球自然限制内带来经济繁荣、社会正义和生活幸福的经济社会的全面转型,而实现路径则依赖于对基础设施、工业产业、教育创新、社会聚合与自然环境等进行投资。由欧洲议会绿党党团委托支持、绿色智库“重构”完成的这一研究报告,试图构建一个相对不利环境下如何达到改变欧洲经济与社会状况的投资水平的金融体制。它认为,欧盟每年需将GDP的2%投资到2020年时实现CO2排放减少30%目标的工作中,并建议财源的主体应是私人投资,同时国家创造必需的激励和支持以吸引这些私人投资。
