Social Stratification and the Division of Household Labor in Japan: The Effect of Wives' Work on the Division of Labor among Dual-earner Families

Abstract:  This article explores the relationship between social stratification and the division of household labor by examining how the contribution to housework by husbands in dual-earner families varies across the Japanese social stratification structure. First, I review previous studies concerning the determinants of husbands' participation in housework and construct four hypotheses regarding the relative resources explanation, the time constraints explanation, the ideology/sex role explanation, and the alternative manpower explanation. Second, I examine the empirical support for these hypotheses in dual-earner couples and the effect of social stratification on husband's participation in housework, which has not been studied thus far. Third, I investigate the effect of social stratification in more detail. According to the results of TOBIT regressions and other supplementary analyses, the principal findings are as follows:

• 1) 

  the relative resources explanation is not supported;

       

Premarital Cohabitation and Housework: Couples in Cross‐National Perspective

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework.     

Attracting Micro‐Enterprises To Learning

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’.     

The Division of Household Labor in Germany and Israel

We compare the patterns of household division of labor in Germany and Israel—two countries that share key elements of the corporatist welfare regime but differ in their gender regimes—and evaluate several hypotheses using data from the 2002 International Social Survey Program. Although time constraints and relative resources affect the division of household labor and women’s housework in both societies, we find that in Germany the gender order of household labor is more rigid, whereas in Israel the spouses’ linked labor market status exerts distinctive effects. We also find significant relationships between gender ideology and the division of household labor. We discuss the theoretical advantages of approaching the comparative study of gender inequality from the vantage point of family and gender regimes.     

手工业社会主义改造及其效率分析(1953—1956年)——基于浙江的研究

20世纪50年代,国家对手工业进行合作化改造。在此过程中除了为手工业提供必要的技术、资金、原料等方面的支持外,发生最大变化的是手工业的生产关系,国家取代以往众多的商人、工场主,成为实际意义上的“包买商”,试图以社会化大生产的方式来提高手工业的生产力,进而壮大社会主义经济成分。但合作化后期所反映出来的种种问题揭示了只有在生产关系基本适应生产力的情况下,才能真正、有效地推动生产力的发展。     

外部经济、企业分工与产业集聚

从资源共享、专业化生产、交易成本的节约、创新利益四个方面分析了产业集聚的经济动因;采用超边际分析方法建立了企业分工模型,并在此基础上推演出产业集群的自组织演化模型。认为外部经济是产业集聚的经济动因,企业分工协作关系的产生和深化则是产业集群形成和发展的关键。     

创业投资利益分割模型研究:基于创业企业家视角的分析

创业企业对创业企业家的激励是否有效决定着创新的成败。为了研究创业投资中的利益分割问题,从创业过程的特征出发,本文首先分析创业企业家的角色特征,应用间接定价理论和交易效率比较,结合委托-代理模型,构造了基于对创业企业家间接定价的创业企业利益分割的两部动态规划模型,并进一步探讨了债权型和股权型利益分割合约的使用条件和创业企业管理团队的选择问题。研究表明:创业企业家和创业资本家的利益分割合约是基于两部动态规划的优化问题;债权型与股权型合约作为利益分割机制对于创业企业家和资本家的效用取决于各自对未来的预期;只有满足一定条件下,创业企业才倾向于选择能力较高的第三方团队充当企业管理者;在能力同等条件下,创业企业倾向于选择创业企业家充当创业企业的管理者。     

好友推介激励机制中在线消费者依附模式研究

社会化网络的发展增加了人们在互联网上的好友资源,好友推介激励机制也具有了更多的推介对象.基于依附理论,将网络消费者进行分类,运用实验研究的方法探讨了好友推介激励机制情景下依附模式对推介双方行为模式,以及奖金分配方式公平性的影响.实验结果表明,依附回避,负向影响邀请者的出价和被邀请者的采纳;依附焦虑,正向影响邀请者的出价和被邀请者的采纳.为了达成成功的好友推介,商家应该依据消费者的依附模式设计好友推介激励机制.
