GENDER EARNINGS DIFFERENTIALS AND REGIONAL ECONOMIC DEVELOPMENT IN URBAN CHINA, 1988–97

Gender earnings differentials in urban China by region and their changes during the first decade of economic reform are examined. It is found that the female–male earnings ratio increased during the early stage of reform. The male earnings premium, overall, showed an increasing trend in the later stage of reform. Decomposition of the gender earnings differential reveals that a relatively lower percentage of the differential could be explained by gender differences in productive characteristics in the fast growing regions and in regions with a rapid pace of reform. The cross-sectional results highlight the possible existence of gender discrimination, particularly in the later stages of economic reform and development. Both market competition and the effects of wage decentralization play a role in shaping the gender earnings differentials. Gender earnings differentials varied by region and over time, generally in tandem with the pace of economic reform and development. The decomposition of the over time changes in the earnings gap indicated that improvement in the productive characteristics of females during the reform period constantly enhanced the earnings of females relative to those of males. The changes over time in the return to female characteristics, however, work to counter any narrowing of the gender earnings gap.

西部高校财务预警与财务风险防范研究

为适应高校教育大众化要求,高校进入了规模扩张阶段,而政府投入的不足,使高校负债发展成为必然选择,这无形中加大了高校办学的财务风险。本文通过分析西部高校财务风险成因,提出应建立财务预警系统,并采取相应的风险防范措施,以有效控制西部高校财务风险的发生。     

Bootstrap and Pretest J-Type Non-Nested Tests for Orthogonal Regression Models: Some Monte Carlo Evidence

This paper compares the size and power of two J-type tests for weakly correlated or nearly orthogonal non-nested regression models: a bootstrap and a pretest test. The latter seems to outperform the former in terms of its size characteristics, especially when the alternative model has more non-nested regressors and the orthogonality between the two sets of regressors is severe. The bootstrap test does better in terms of power.

社会事业家理论评析

1980年代末以来,关注民间组织卓越领导人的社会事业家理论开始建构.领袖-特质理论认为社会事业家是以其对社会使命的不懈追求和强烈的伦理整合性来促成社会价值的最大化.建构主义理论认为社会事业家嵌入特定的组织结构和规则当中,并致力于创造新的制度或改造既有制度.社会事业家有四种理想形态:传统的创业型社会事业家、传统的拓展型社会事业家、自给创业型社会事业家和自给拓展型社会事业家.我国应从理念到制度层面培育社会事业家.
