An empirical analysis of the social security disability application,appeal, and award process

We provide an empirical analysis of the Social Security disability application, award, and appeal process using the Health and Retirement Survey (HRS). We show that the appeal option increases the award probability from 46% to 73%. However, this comes at the cost of significant delays: the duration between application and award is over three times longer for those who are awarded benefits after one or more stages of appeal. Our results reveal the importance of self-selection in application and appeal decisions. In particular, an individual's self-assessed disability status emerges as one of the most powerful predictors of application, appeal, and award decisions.

GMM estimation of social interaction models with centrality

This paper considers the specification and estimation of social interaction models with network structures and the presence of endogenous, contextual, correlated, and group fixed effects. When the network structure in a group is captured by a graph in which the degrees of nodes are not all equal, the different positions of group members as measured by the Bonacich (1987) centrality provide additional information for identification and estimation. In this case, the Bonacich centrality measure for each group can be used as an instrument for the endogenous social effect, but the number of such instruments grows with the number of groups. We consider the 2SLS and GMM estimation for the model. The proposed estimators are asymptotically efficient, respectively, within the class of IV estimators and the class of GMM estimators based on linear and quadratic moments, when the sample size grows fast enough relative to the number of instruments.     

A model for the influence of social interaction and social support on female expatriates' cross-cultural adjustment

This paper offers a model to describe the way in which female expatriates develop relationships and utilize those relationships to become cross-culturally adjusted. This model includes three predictive components affecting cross-cultural adjustment. The first includes the factors affecting whether a woman is able to form relationships on the expatriate assignment. These antecedents can include the female expatriate's personality, the cultural norms towards women, her language skills and the availability of possible opportunities for interaction. The second component includes the various sources of social interaction and social support (e.g. family members, and host national colleagues). The third component describes the nature of a female expatriate's social interaction and social support (e.g. emotional, informational and instrumental). Practical considerations for multinational organizations sending female expatriates are offered.

城市空间、社会分层与社会和谐

我国90年代以来的城市化浪潮,不仅是一个规模扩展的过程,也是一个利益重构与社会分化的过程,并带来城市居住空间上的"阶层化".这种社会阶层在生活空间上的疏离与隔膜对社会和谐造成负面影响,解决的途径可选择:适度的多样化混居;改造和提升弱区位的公共服务;充分考虑到外来工的生活居住问题等.     

生活质量--21世纪质量工作的重要新领域(3)健康生活质量

１体质与物质生活质量物质是健康的基础。无论什么人，为了保持身体健康，都必须使自己的物质生活达到一定的水平。可是，在具备了一定的物质生活条件之后，却并不一定就能保证身体健康。从１９９７年到２０００年，国家体育总局和教育部的相关机构，用三年时间进行了国民体质监测，监测结果表明：我国公民的体质总体上呈逐年下降趋势，主要表现有三：一是身高降低；二是体重增大；三是机能减退。值得注意的是，这三年正是我国人民物质生活质量大幅度提高的三年。为什么物质生活质量提高了，国民体质反而下降了呢？专家们经过分析后认为，最…     

Altruism, redistribution and social insurance

The paper examines the influence of altruism on voluntary transfers and government redistribution in a simple model: two jobs of different productivity are assigned by chance to two individuals. Ex ante the individuals are identical, ex post they have different incomes. The first part of the paper examines voluntary transfers determined ex post or agreed upon ex ante in the absence of altruism. In the second part, the influence of altruism is examined. Altruism is modelled as a pure public good: the minimum consumption (or income, since there is only one consumption good). Both individuals can contribute to its provision, one person by earning wage income, the other by voluntary transfers. The ex ante solutions generally lead to higher expected welfare but create several incentive problems. Only lump-sum transfers are considered.

Client–consultant interaction: Capturing social practices of professional service production

Based on the investigation of seven consultancy projects within an international technical consulting firm, we identify three major practices that characterize client–consultant interaction – shaping impressions, problem-solving, and negotiating expectations – and discuss their respective characteristics, activities, and contingencies. Our discussion of these practices provides not only a more differentiated picture of client–consultant interaction but also uncovers the critical role that clients play in these practices.     

Social distance,heterogeneity and social interactions

A crucial ingredient in social interaction models is the structure of peer groups, which link individuals with similar characteristics. We propose and study a dynamic binary choice model with social interactions in which heterogeneity of peer group effects is modeled introducing diversity in individual characteristics and linking pairwise influences to a social distance between individuals. Our framework allows for mimetic as well as anti-mimetic interactions and a heterogeneous structure of peer groups across individuals. Dynamic equilibria are studied in the limit when the number of agents is large. We show that the model exhibits multiple equilibria resulting from conflicts between various group pressures the individuals are subjected to. We study in particular the correlation in the population at equilibrium between the characteristics of the agents and their decisions: this quantity has an interesting empirical interpretation and solves a simple analytical equation when the number of agents is large. Finally we discuss the empirical content of the model and present a consistent estimator for the parameter describing which is consistent for any typical population regardless of the structure of individual characteristics.     

Job matching, social network and word-of-mouth communication

Workers can find a job either directly or through personal contacts. From this micro scenario, we derive an aggregate matching function that has the standard properties but fails to be homogeneous of degree one. We show that, when the network size increases, on average, the unemployed workers hear about more vacancies through their social network. However, above a certain critical value, job matches decrease with network size. We then establish existence and uniqueness of the labor market equilibrium and study its properties. Finally, we demonstrate that the decentralized market equilibrium is not efficient because of both search and network externalities.
