Barriers to employee rights: Gender,selection, and the labor process

This article applies a labor process analysis to the issue of employment rights in the particular context of gender inequality and unlawful discrimination in the recruitment process. It criticizes conventional perspectives on employee rights for their failure to examine critically managerial power and prerogative and its implications for gender inequality. The article outlines two particular labor process theories of gender divisions and inequality. In exploring the strengths and weaknesses of these more critical perspectives, the article highlights the analytical significance that they ascribe to power asymmetries in the labor process and labor market. Building on this perspective, the analysis then presents empirical data on gender discrimination in the selection practices of contemporary UK organizations. The research material reveals how gender discrimination can be reproduced, rationalized, and resisted. These empirical findings are theorized through a combined labor process analysis of power, knowledge, and identity in recruitment practices. We conclude that labor process analysis facilitates our understanding of the deep-seated barriers that continue to impede the protection of employee rights in workplace practices.

Innovation, Imitation and Intellectual Property Rights: A Note on Helpman's Model

This note analyses the effect of the policy of tightening Intellectual Property Rights (IPR) on the rate of innovation in the North and on the welfare in both North and South in a model which is otherwise identical to Helpman (1993) except in the concept of knowledge capital. We assume that the South based imitated products do not contribute to the knowledge capital in the North. It is shown that the tightening of IPR raises the rate of innovation in the North and may improve the welfare of both North and South. These results are significantly different from those in Helpman (1993).     

Property rights protection and access to bank loans

Poor protection of private property has limited the access to bank loans by private enterprises in developing and transition economies. Under those circumstances, private entrepreneurs have resorted to various ways of enhancing the de facto protection of private property. Using a dataset of 3,073 private enterprises in China, this paper empirically investigates the impact of political participation and philanthropic activities – informal substitutes for the lack of formal protection of private property – on the access to bank loans.     

控股股东、实际控制权与小股东权益保护

股权集中型公司是现代公司的主流组织形态之一,其代理成本主要产生于控股股东与小股东之间存在的利益冲突.通过发行多种类股票、交叉持股和金字塔式控股等方式,控股股东能够获取比与其股权份额相对应的名义控制权更大的实际控制权,因而更容易发生以侵害小股东权益作代价追求控制权私下收益的道德风险行为,致使代理成本高昂.声誉机制和法律手段能够迫使控股股东收敛侵占行为,且法律手段较声誉机制更为有效.在中国,声誉机制对控股股东基本不起作用,保护小股东权益的最为有效的措施是完善相关立法并加大执法力度.     

Institutions matter,but which ones?

The purpose of this paper is to go beyond the narrow focus of the current institutional economics literature in development on the institutions protecting individual property rights, and to look at the economic effects of some other aspects of institutional quality on the development process (like democratic participation rights and institutions to address coordination failures). Another purpose is to suggest an alternative instrumental variable in quantifying the effects of property rights institutions. Finally, we speculate how, on account of distributive conflicts, institutions that have an adverse effect on economic performance often tend to persist for long periods of time in many poor countries.
