Gender effect on housework allocation: Evidence from Spanish two-earner couples

In this paper we study the reasons behind the asymmetric distribution of housework within Spanish two-earner couples. Spouses' housework times are estimated jointly in a bivariate framework using data from the 1991 Work Situation and Time Use Survey. In order to understand the impact of gender-specific factors on the observed allocation of housework, we perform estimations that are in line with the Oaxaca decomposition. Our results suggest that the unequal division of domestic work between wives and husbands in our sample is mainly explained by gender-specific effects rather than by differences in their observable characteristics.

Do stepping-stone jobs exist? Early career paths in the medical profession

In the Netherlands, students who want to become a medical specialist have to enrol in a training program which is in limited supply. During the search for a position as trainee (or “junior medical specialist”), they may accept a temporary job as a medical assistant. We use a micro data set to investigate whether such work experience increases the probability of becoming junior medical specialist. To deal with selectivity, we simultaneously model the transitions from unemployment to trainee, from unemployment to medical assistant, from medical assistant to trainee and from medical assistant to unemployment. We find that a job as medical assistant helps to become a medical specialist. Received: 27 July 2000/Accepted: 31 January 2001 All correspondence to Gerard J. van den Berg.

Self-selection,earnings, and out-migration: A longitudinal study of immigrants to Germany

In this paper we examine the process of out-migration and investigate whether cross-sectional earnings assimilation results suffer from selection bias due to out-migration. Our 14 year longitudinal study reveals that emigrants are negatively selected with respect to occupational prestige and to stable full time employment. Our results show no selectivity with respect to human capital or gender. The likelihood of return migration is strongly determined by the range and nature of social attachments to Germany and origin countries. It is also the highest during the first five years since arrival, and grows higher toward retirement. Selective emigration, however, does not appear to distort cross-sectional estimates of earnings assimilation in a relevant way.All Correspondence to Douglas S. Massey.

Advice from women and men and selection into competition

Advice processes are omnipresent in our professional and private lives. We use a laboratory experiment to study how gender and gender matching affect advice giving and how gender matching affects advice following about entry into a real-effort tournament. For advice giving we find that women are less likely than men to recommend tournament entry to advisees than are intermediate performers. Furthermore, women maximize less often the expected earnings of advisees than intermediate performers. For advice following we find that men enter the tournament significantly more often than women in the intermediate-performance group do. Gender matching does not seem to affect advice giving or following. Overall, when it is less clear what the better advice or decision is, gender differences emerge. These results are consistent with findings in other areas that document that gender differences emerge in situations that are more ambiguous.     

Efficiency Evaluation in Search Advertising

In this article, we use data envelopment analysis combined with principal component analysis to evaluate the efficiency of online retailers in search advertising. We examine various efficiency model specifications involving several resource and performance‐related variables in search advertising. Our analysis based on 200 retailers suggests different efficiency patterns for multichannel and Web‐only retailers. The results of our efficiency pattern analysis indicate that the performance metrics, impressions, online sales, click‐through rate, and conversion rate together reveal differences in efficiency mainly for multichannel retailers. On the other hand, ad positions in sponsored and organic links reveal differences in efficiency for Web‐only retailers. In terms of overall efficiency, we find that multichannel retailers occupy relatively most of the top positions. These results contribute to organizational level understanding of search advertising practices in online retailing and offer insights into keyword management, resource utilization, and performance metrics in search advertising campaigns.     

DOES RELATIONSHIP SPECIFIC INVESTMENT DEPEND ON ASSET OWNERSHIP? EVIDENCE FROM A NATURAL EXPERIMENT IN THE HOUSING MARKET

In this paper, I test the most basic prediction of Grossman and Hart (1986, The Costs and Benefits of Ownership: A Theory of Vertical and Lateral Integration. Journal of Political Economy, 691–719): allocations of asset ownership that expose a party to ex‐post expropriation reduce this party’s ex‐ante relationship‐specific investments. In the empirical context of the German housing market, I find that relationship‐specific investments, such as bathroom renovations, are more frequent if the occupant is protected against expropriation because he owns his home. To avoid the endogeneity of the homeownership allocation, I rely on the natural experiment of the German reunification: under the communist regime, ownership existed but was economically meaningless; yet after reunification, ownership unexpectedly reacquired legal force.     

ON THE THEORY OF ETHNIC CONFLICT

When considering engaging in conflict to secure control of a resource, a group needs to predict the amount of post‐conflict leakage due to infiltration by members of losing groups. We use this insight to explain why conflict often takes place along ethnic lines, why some ethnic groups are more often in conflict than others (and some never are), and why the same groups are sometimes in conflict and sometimes at peace. In our theory ethnic markers help enforce group membership: in homogeneous societies members of the losing group can more easily pass themselves as members of the winning group, and this reduces the chances of conflict as an equilibrium outcome. We derive a number of implications of the model relating social, political, and economic indicators such as the incidence of conflict, the distance between ethnic groups, group sizes, income inequality, and expropriable resources. One of the insights is that the incidence of ethnic conflict is nonmonotonic in expropriable resources as a fraction of total resources, with a low incidence for either low or high values. We use the model’s predictions to interpret historical examples of conflict associated with skin pigmentation, body size, language, and religion.     

Response to Ross’s Comment to Miccio-Fonseca and DeFeo

ABSTRACT

Response to Ross on his comments regarding my purported misunderstanding of Ross’s article and the DSM-V (Ross, 2015). Although Ross claims he offered no personal opinions of any kind in his commentary, undeniably there were two separate and independent comments in (Miccio-Fonseca (2015) and DeFeo (2015) addressing similar issues. Is this coincidental? This author maintains the stance expressed in the cited commentary.     

C2C网络零售环境下负面评价信息的反馈策略研究

基于已有研究成果,以店铺的选择意愿作为反馈策略有效性的衡量指标,构建出一个理论模型,并通过实证分析的结果对C2C网络零售环境下负面评价信息的反馈策略提出了自己的建议。研究发现,在控制住其他影响因素后,负面评价信息类型与反馈策略方式成为影响店铺选择意愿的两个要素,二者之间还存在着显著的交互效应。基于这一研究成果,本研究提出两点建议。第一,店铺运营者应首先对感性负面评价信息进行反馈,先后有序地解决问题。第二,店铺运营者针对感性负面评价信息进行反馈时,应更多地运用理性反馈策略展开工作;而针对理性负面评价信息进行反馈时,则应该更多地运用感性反馈策略展开工作,统筹兼顾地解决问题。     

代表性与民主性：中国共产党对人大代表选举的认知与实践

发扬民主性,体现代表性,是中国共产党对人大代表选举的基本认知。这种认知直接影响了中国人大代表选举的具体制度设计与运作逻辑,反映在人大代表名额分配、选区划分与候选人提名等各环节中。民主性与代表性的结合,既是中国人大代表选举制度的特色与优势,也是中国政治发展的客观要求。如何在进一步彰显民主性的前提下,实现代表性与民主性二者间的良性互动,是中国人大代表选举制度发展的基本价值取向。
