Children of Migrants: The Cumulative Impact of Parental Migration on Children’s Education and Health Outcomes in China

Since the end of 1990s, approximately 160 million Chinese rural workers migrated to cities for work. Because of restrictions on migrant access to local health and education systems, many rural children are left behind in home villages to grow up without parental care. This article examines how exposure to cumulative parental migration affects children’s health and education outcomes. Using the Rural-Urban Migration Survey in China (RUMiC) data, we measure the share of children’s lifetime during which parents were away from home. We instrument this measure of parental absence with weather changes in their home villages when parents were aged 16–25, when they were most likely to initiate migration. Results show a sizable adverse effect of exposure to parental migration on the health and education outcomes of children: in particular, boys. We also find that the use of the contemporaneous measure for parental migration in previous studies is likely to underestimate the effect of exposure to parental migration on children’s outcomes.     

日本电力自由化的现状与展望

上世纪90年代以来,日本电力产业实施了大幅度地自由化改革.于1995年引入了批发电力的竞标制度,并于2000年在零售业开始对大用户实施了自由化.自由化改革既给产业发展带来了好处,也存在着弊端.如消费者可以自由选择电力公司等,但是其反面则是担心对稳定供给的损害.更为重要的是,作为网络服务的电力行业,发电、输电和配电在物理上是不可分离的,法理上的分离遇到了资本私有原理与共用设备之间存在的矛盾.而且,对经营者交叉进入具有不同性质的产业的经营行为,缺乏有效的法律规制.自由化改革暴露出来的弊端,需要决策者们更审慎地思考.     

Nonmarket networks among migrants: evidence from metropolitan Bangkok,Thailand

This paper examines the nonmarket interactions among migrants in the urban labor market of Bangkok, Thailand. We test whether the population size and the labor-market performance of previous migrants have externalities to new migrants who have moved from the same province of origin. Our empirical results, which control origin fixed effects, time fixed effects, and origin- and year-specific correlated shocks, show that (1) the relative population size of previous migrants in the market decreases the employment probability of new migrants (substitution effect), (2) the employment probability of previous migrants increases that of new migrants (positive externalities), and (3) when the employment probability of previous migrants is high, however, the scale effect becomes positive, which demonstrates a threshold in the informational scale economies. The results imply that positive informational scale effect dominates negative substitution effect when the efficiency of previous migrants is sufficiently high in the destination labor market.

Recurrence formula on the joint distribution of sample skewness and kurtosis under normality

Abstract

Two recurrence relations with respect to sample size are given concerning the joint distribution of skewness and kurtosis of random observations from a normal population: one between the probability density functions and the other between the product moments. As a consequence, the latter yields a recurrence formula for the moments of sample kurtosis. The exact moments of Jarque-Bera statistic is also given.     

On the level probabilities for useful partially ordered alternatives in the analysis of variance

In the analysis of variance, we often encounter situations in which we want to test the null hypothesis of homogeneity of the normal means against various partially ordered alternative hypotheses. We study likelihood ratio tests for three useful types of alternatives: d-star, bipartite and broom tree. Especially, we give computational formulas for the level probabilities of the alternative types. The results permit us to obtain critical values for practical use.

What Determines the Size of the Nonprofit Sector?: A Cross-Country Analysis of the Government Failure Theory

This article is an empirical examination of the government failure theory using a cross-country data set. The government failure theory is represented in the major existing literature as providing a sound explanatory basis for an interesting characteristic of the nonprofit sector, that is, there is a large variability in nonprofit sector size from one place to another. Salamon et al. (Social origins of civil society: An overview, Working Papers of the Johns Hopkins Comparative Nonprofit Sector Project, 2000) examined this theory using the Johns Hopkins Comparative Nonprofit Sector Project (CNP) data set, and consequently rejected the government failure theory. However, by applying the panel analysis approach to the CNP data set, this article shows that the government failure theory should not have been so easily rejected.     

Voluntas Symposium: Comments on Salamon and Sokolowski’s Re-conceptualization of the Third Sector

With their “Beyond Nonprofits: Re-conceptualizing the Third Sector”, Salamon and Sokolowski have made an important contribution to the ongoing debate on how to define the third sector. This Voluntas symposium brings together the comments of five leading scholars both supportive and critical of the new definition. The comments are based on a debate held at the conference of the International Society for Third Sector Research, in Stockholm in 2016.     

Students’ Vocational Choices and Voluntary Action: A 12-Nation Study

Previous research on student involvement suggested that business and engineering students manifest lowest rates of voluntary action. Similarly, it was thought that social science students are the most involved in voluntary action, with students of natural sciences and humanities in the middle. However, there were very few studies that empirically compared these assertions. Furthermore, these assertions were not investigated from cross-cultural perspectives. Based on a study of students in 12 countries (N = 6,570), we found that even when controlling for background variables, social science students are actually less engaged in voluntary action than other students. Engineering students are higher than expected on voluntary action while students of humanities are the most involved in voluntary action. When studying these differences in the 12 selected countries, local cultures and norms form different sets of findings that suggest that there is no universal trend in choice of academic field and voluntary action.     

What's Driving Brazil‐Japan Migration? The Making and Remaking of the Brazilian Niche in Japan

Abstract: Since the late 1980s the Brazilian population in Japan has steadily increased, despite the long‐term recession in the late 1990s. In this paper we will examine the mechanism of the constant increase of Brazilians in Japan, focusing on the institutional context of their incorporation into the Japanese labor market. On the demand side, Brazilians solved an acute labor shortage in the economic boom period, but long‐term recession and casualization of the labor market made them compete with other peripheral workers such as Japanese women and the aged. Thus Brazilians have been marginalized within the secondary labor market since the late 1990s. On the supply side, recruiting agencies and labor contractors established a “just‐in‐time” labor delivery system, which enabled “flexible staffing” in a highly fluctuating labor market. As a result, demand and supply for Brazilian workers is still on the increase. Working in Japan is getting less attractive for Japanese Brazilians but is more of a viable option for them, driving further migration from Brazil to Japan.
