职场排斥对员工创新行为的影响 ——组织承诺与组织认同的双重中介作用

如何激发员工创新行为是企业关注的重点问题，职场排斥是员工在工作中经常面对的问题，也是影响创新行为的一个重要原因。以自我验证理论为基础，探讨职场排斥对员工创新行为的影响机制。采用多元回归模型对193份员工问卷进行分析，结果表明：职场排斥对组织承诺、组织认同和员工创新行为具有显著负向影响；组织承诺和组织认同在职场排斥与创新行为间起中介作用，职场排斥通过降低员工组织承诺和组织认同，进而抑制员工创新行为。     

转股价修正条款价值与可转债定价研究

在研究可转债定价问题时考虑转股价修正条款是十分必要的。尤其是在2008年的熊市中,各可转债纷纷调低转股价,转股价修正条款给予了投资者保护作用不容忽视。基于AFV模型,本文建立了包含转股价修正条款的定价模型,并利用有限差分法进行数值求解。

The Dynamics of a Racialized,Gendered, Ethnicized,and Economically Stratified Society: Understanding the Socio-Economic Status of Women in Zimbabwe

Feminist literature attempting to understand the status of women in Zimbabwe has seldom considered patterns of social exclusion and the dynamics of a racialized society that institutionalized racial supremacy as an ideology for organizing social life. Even now, too often we believe, feminist theorists analyze the status of women with the assumption that patriarchy is the single source of the oppression of women. Using the notion of a racialized society we account for the workings of gender oppression within the historical context of Zimbabwe. We show how in a racialized society, gender, race, ethnicity, and class operate intricately together to relegate African women to the lowest socio-economic status. Even with policies to redress earlier imbalances, women endure all forms of injustices. We focus on the informal sector as illustrative of one sector where these injustices continue.     

我国煤电价格联动机制实施困境分析及其前景构想——美国电力自动调节条款的经验与启示

我国煤电价格联动机制的推出与实施过程遭遇了很多障碍与反复。文章借鉴美国电力行业的自动调节条款的实施背景、本质、条件、作用机理和保障,分析了当前我国煤电联动过程中遇到的困境,找出了缺乏规制起点、承载多重目标、条款模糊等症结所在,并描绘了对该机制的前景构想。     

Comparative Studies in Public Administration and Public Policy

This article offers a conceptual framework and examines a range of cases around the theme of comparative studies in public policy and public administration. It sets the scene for a discussion about issues of comparative analysis in public policy and is aimed at generating debate regarding what comparative analysis can achieve. Finally, it turns our attention to what should be the underlying principles in comparative research and in comparative discourse.     

Avoiding arbitrary exclusion restrictions using ratios of reduced-form estimates

We show how to obtain coherent structural-form (SF) exclusion restrictions using the reduced-form (RF) parameter ratios. It will be shown that an over-identified SF corresponds to a group of regressors sharing the same RF ratio value; those regressors should be excluded jointly from the SF. If there is no group structure, then the SF is just-identified; in this case, however, it is no longer clear which regressor should be excluded. Hence, just-identified SF’s are more arbitrary than over-identified SF’s in terms of exclusion restrictions. This is in stark contrast to the notion that the former is less arbitrary than the latter, because the former excludes fewer regressors. We formalize these points, and then suggest to find the number of modes in the estimated RF ratios as a way to find groups in the ratios. For this purpose, an informal graphical method using a kernel nonparametric method and a formal modality test are employed. An empirical example with selling price in a residential real estate market and duration on the market as two endogenous variables is provided.

Prejudice, exclusion, and compensating transfers: the economics of ethnic segregation

Prejudiced groups self-segregate and exclude others. This is observed in South African apartheid, in the exclusion of Eastern European or Muslim immigrants from Western Europe and in ghettos formed by immigrants in many countries. In the United States, minorities (mostly African Americans) are segregated in central cities and wealthier European Americans reside predominantly in the suburbs. A fully closed general equilibrium model of the last case is presented. The model treats land, labor and product markets. Most whites flee the inner city for white-dominated suburbs. This benefits blacks by lowering inner city rents relative to wages. When whites are weakly prejudiced, exclusion from the suburbs hurts whites as well as blacks. But when whites are strongly prejudiced, a lump sum endowment transfer from whites to blacks can split the gains-from-trade: whites can pay transfers to blacks in exchange for blacks accepting exclusion. The transfer needed to compensate blacks is large if blacks are strongly hurt by exclusion and small if they are only slightly hurt. How much transfers to US central cities and to the poor compensate American blacks for the effects of exclusion is an open question.
