Return to education in Finland

This study presents estimates of the return to education in Finland using an individual-level data set that also includes ability measures and information on family background. It is found that ability test scores have a strong effect on the choice of education and on subsequent earnings. Estimating the return to education with no information on ability leads to an upward bias in the estimates. However, this bias is more than offset by a downward bias caused by endogeneity or measurement error. Instrumental variables estimates that utilize family background variables as instruments produce estimates of the return to schooling that are approximately 60% higher than the least squares estimates.     

Quantile regression with sample selection: Estimating women's return to education in the U.S.

This study uses quantile regression techniques to analyze changes in the returns to education for women. The data used is the March Current Population Survey for the years 1968, 1973, 1979, 1986 and 1990. The first step in estimating the single (linear) index selection equation uses Ichimura's (1993) semiparametric procedure. To correct for an unknown form of a sample selection bias in the quantile regression, the second step incorporates a nonparametric method, using an idea similar to one developed by Heckman (1980) and Newey (1991) for mean regression, and Buchinsky (1998) for quantile regression.  The results show that: (a) the returns to education increased enormously for the younger cohorts, but very little for the older cohorts; (b) in general the returns are higher at the lower quantiles in the beginning of the sample period and higher at the higher quantiles by the end of the sample period; (c) there is a significant sample selection bias for all age groups at almost all quantiles; (d) toward the end of the sample period there is a significant convergence of the returns at the various quantiles, especially for the younger cohorts and age groups; and (e) the semiparametric estimates of the selection equation are considerably different from those obtained for a parametric probit model.     

征地留用地安置模式适用范围的定量评价与实证研究

留用地安置模式是20世纪80年代以来,全国各地相继使用的土地征用的安置模式.但留用地安置模式有其特有的适用条件的,不能简单复制.论文的研究目的就是通过定量评价的方式确定留用地安置的适用范围,为各地实施留用地安置模式给出一定的参考.论文就湖南省实施情况的调研结果,采用特尔菲法,对适用条件进行了评价,井以湖南省为例,就不同区域的适宜性进行评价.结果表明留用地安置模式只在城市规划稳定、经济发展水平较高,房地产市场成熟,土地需求较为旺盛的地区实施.     

上海股票市场规模效应的实证研究

规模效应是指公司规模与收益率之间存在的反向关系，即小规模公司较大公司而言有着更高的收益率。本文从上海证券市场随机抽取60只股票作为数据样本，对其从2007年1月到2009年6月之间的公司数据进行实证研究，得出上海股市存在着规模效应这一结论。     

社会转型期间教育爱的缺失与回归

由于其处于社会转型期,教育爱正在经受着不同程度的挑战与侵蚀,进而导致了许多教育问题。因此需要审视我们的教育爱对于处于这一个特殊时期存在的一些缺失问题,进而从形成以学生为主体的教育爱的品质,以接受为前提的教育爱的方式等方面内容对于教育爱的回归进行探究。     

Antecedents and consequences of the perceived adjustment of Japanese expatriates in the USA

The present study was designed to better understand the antecedents and consequences of expatriate adjustment in an international assignment. The researchers surveyed Japanese expatriates assigned to the United States. Structural equation modeling was utilized to test our hypotheses and model. The results indicated that previous knowledge of the host country, language proficiency, willingness to communicate and perception of the novelty of the host culture were differentially related to expatriates' adjustment to the host country. General and work adjustments were negatively related to expatriates' intent to return early. In addition, interrelationships among the adjustment dimensions were examined and the results indicated that general adjustment leads to work adjustment, which, in turn, influences interactional adjustment. Implications for future research are presented.

西洋南瓜UGU生产的成本效益分析

本文通过成本效益分析方法对尼日利亚拉各斯市的西洋南瓜UGU生产利润及其影响因素进行了分析。文中通过“滚雪球”式抽样方式选取了60个南瓜瓜农，多数接受调查的瓜农在31～45岁之间，男女性分别为56．7％和43．3％，他们多数（68．3％）没有接受过正规教育。60％的接受调查者其生产成本较低，其成本每月不到1500奈拉。多数接受访问者其收入高于成本。南瓜生产在促进农民脱贫中起到了重要作用。研究表明教育水平、与推广机构的联系以及耕作经验对南瓜生产具有积极作用。因此，应促进瓜农与推广机构的联系以提高瓜农的收入，同时对于那些没有种植经验的瓜农也要给予帮助。     

The disparity between long-term and short-term forecasted earnings growth

We find the disparity between long-term and short-term analyst forecasted earnings growth is a robust predictor of future returns and long-term analyst forecast errors. After adjusting for industry characteristics, stocks whose long-term earnings growth forecasts are far above or far below their implied short-term forecasts for earnings growth have negative and positive subsequent risk-adjusted returns along with downward and upward revisions in long-term forecasted earnings growth, respectively. Additional results indicate that investor inattention toward firm-level changes in long-term earnings growth is responsible for these risk-adjusted returns.
