Field of study variation throughout the college pipeline and its effect on the earnings gap: Differences between ethnic and immigrant groups in Israel

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree.

Euro area inflation as a predictor of national inflation rates

The stability of inflation differentials is an important condition for the smooth working of a currency area, such as the European Economic and Monetary Union. In the presence of stability, changes in national inflation rates, while holding Euro area inflation fixed contemporaneously, should be only transitory. If this is the case, the rate of inflation of the whole area can also be interpreted as a predictor, at least in the long-run, of the different national inflation rates. However, in this paper we show that this condition is satisfied only for a small number of countries, including France and Italy. Better convergence results for inflation differentials are, instead, found for the USA. Some policy implications are drawn for the Eurozone.     

Long-term consequences of youth volunteering: Voluntary versus involuntary service

Despite the renewed interest in youth volunteering in recent years, there remain major gaps in our knowledge of its consequences. Drawing data from the National Longitudinal Study of Adolescent to Adult Health, we examine the long-term effects of youth volunteering on the civic and personal aspects of volunteers’ lives. Our results suggest that youth volunteering has a positive return on adult volunteering only when it is voluntary, and that net of contextual factors neither voluntary nor involuntary youth service has a significant effect on adult voting. Regarding personal outcomes, our findings indicate that the psychological benefits of youth volunteering accrue only to voluntary participants, whereas both voluntary and involuntary youth service are positively associated with educational attainment and earnings in young adulthood. Taken together, these results lend support to the case for youth volunteer programs, though the civic benefits of these programs appear to be less dramatic than generally suggested.     

Earnings Differentials of Seafarers

I investigate the earnings differentials among union and nonunion seafarers, across seafarer occupations, and with respective to other transport operatives. The empirical results suggest that the union and nonunion weekly earnings of captains/mates are comparable, and the union earnings gap for sailors/deckhands is positive. The union (nonunion) weekly earnings of captains/mates are 14.7 (30.5) percent greater than those of sailors/deckhands; the union weekly earnings of captains/mates (sailors/deckhands) are 12.6% greater (9.5% less) than those of truck drivers; and the nonunion weekly earnings of captains/mates (sailors/deckhands) are 33.0% greater (6.2% less) than those of truck drivers. The sailor/deckhand and truck driver earnings differentials are contrary to the general belief that the earnings of truck drivers are less than those of other operative occupations involved in transporting intermodal cargo.

How important is homeland education for refugees’ economic position in The Netherlands?

We use data on refugees admitted to The Netherlands that include registration of education in their homeland by immigration officers. Such data are seldom available. We investigate the quality and reliability of the registrations and then use them to assess effects on refugees’ economic position during the first 5 years after arrival. The most remarkable finding is the absence of returns to higher education.

企业社会责任与盈余管理——对深圳A股的实证研究

企业社会责任有利于减少内部管理人员滥用信息优势,增加财务透明度。论文以深圳A股工业上市公司为样本,运用扩展琼斯模型探讨了企业社会责任与盈余管理之间的关系。研究结果表明:企业社会责任与盈余管理之间呈显著负相关;同时,社会责任行为也可能成为上市公司盈余平滑和在亏损年度调减或调增收益行为的掩护。     

关于我国“民工荒”与农民工福利待遇的探讨

2004年前后在我国珠三角等地出现了"民工荒"现象,这是否意味着我国农村劳动力乡-城迁移已经接近尾声,从而农村实现土地规模化经营的时机已经成熟?本文根据托达罗模型,利用成本-收益分析法,提出这是农民进城务工收入与务农收入之间差距缩小导致的农村劳动力做出的非迁移决策.并探讨了设置农民工福利项目对劳动力市场和企业雇佣成本的影响.     

The Gender Pay Gap in the US: Does Sector Make a Difference?

Analyses of data from the 2000 US Census show that the gender pay gap differs by sector of employment and according to the part of the earnings distribution that is considered. The gender pay differential in the private sector in the US does not display either the glass ceiling or sticky floor effects that have been reported for many other countries. The government sector is, however, characterized by a distinct sticky floor effect in the female–male pay differential. Regardless of the sector of employment, females have lower hourly rates of pay than men across the entire earnings distribution.

当代青年择偶的收入观——郎才女貌悖论

采用2002年中国住户调查数据,本文对当前我国婚姻市场的择偶标准进行了实证研究。在传统社会,高收入的男性和专职于家庭事务的女性被认为是完美的结婚组合(郎才女貌),因此当时的择偶标准体现为收入上的异质性。而本文通过实证研究发现,当前收入水平相当的男女更可能结为夫妻。现在与过去择偶标准的不同导致了郎才女貌悖论的出现。最后,本文阐述了婚介机构的重要性。
