Gender gaps in early wage expectations

Using detailed data from a unique survey of high school graduates in Germany, we document a gender gap in expected full-time earnings of more than 15%. We decompose this early gender gap and find that especially differences in coefficients help explain different expectations. In particular, the effects of having time for family as career motive and being first-generation college student are associated with large penalties in female wage expectations exclusively. This is especially true for higher expected career paths. Resulting expected returns to education are associated with college enrollment of women and could thus entrench subsequent gaps in realized earnings.     

Vocational training and labor market outcomes in the Philippines

The paper analyzes the labor market outcomes of graduates of post-secondary technical and vocational education and training (TVET) in the Philippines. Using household data for 2015–2016, the results show significantly higher wages for TVET graduates relative to those who entered the job market with a secondary school education or below. However, individuals who both trained in TVET and pursued tertiary (university) education tend to have a lower wage than those with secondary school education or below. This counterintuitive result may be partly explained by the tendency for such dual-level individuals to complete the lowest level of TVET. Graduates of TVET are found more likely to be employed compared to individuals who only studied at secondary school or below as well as those who studied at the tertiary level.

事业单位工资制度改革背景下的图书馆绩效管理与绩效工资分配体系研究——以湖南大学图书馆为例

岗位绩效工资制度的实施是事业单位工资制度改革的必然趋势。文章以湖南大学图书馆为例,探讨了事业单位工资制度改革背景下图书馆绩效管理的实施,以及绩效工资总量确定与个人绩效工资确定的办法,并提出了图书馆作为公益性、多样化事业单位进行绩效管理与绩效工资发放过程中的注意事项。     

关于微分中值定理的进一步研究

针对微分中值定理进行了更深入的探讨。用两种方法分别证明了拉格朗日中值定理和柯西中值定理,并给出了它们之间的相互关系以及几何意义。最后通过具有代表性的典型例题说明微分中值定理的应用。     

测算养老保险替代率的模型和方法

近年来,随着中国养老社会保险制度的逐步确立,基本养老保险中的替代率问题受到了人们越来越多的关注。本文根据中国现行基本养老保险的规定,提出并建立了测算养老保险替代率的模型和方法,并运用实际数据进行了初步的测算,最后由测算的结果得出以下结论：一、中国基本养老保险中由于男女职工退休年龄的不同,直接导致女性职工退休后替代率低于男性职工替代率;二、保险替代率随着工资增长率的增加将随之下降,且收入越高者,其退休后的替代率越低。随着中国经济的不断发展,工资水平的不断提高,原先高替代率低保障的养老保险,必将为低替代率高保障的养老保险所取代。
