Discussion of “How Banks' Value-at-Risk Disclosures Predict their Total and Priced Risk: Effects of Bank Technical Sophistication and Learning over Time”

Liu et al. (2004, this issue) show that technical sophistication and learning over time help improve the ability of bank trading portfolios' value-at-risk (VaR) disclosures to predict future trading income risk, and that trading VaRs predict bank-wide total risk and systematic risk. While the results suggest that VaRs are a reliable measure of risk for the sample firms, the study's incremental contribution is limited because of the nature of the sample firms and problems in variable measurement.

Tax penalties on fluctuating incomes: estimates from longitudinal data

Progressive personal income taxes can cause individuals with fluctuating incomes to pay more taxes over time than individuals with constant incomes of the same average value. The implicit tax penalty violates principles of equity and may harm efficiency by discouraging risk-taking activities, such as entrepreneurship. This paper uses longitudinal data to estimate the tax penalties in six panels of Canadian data from 1993 to 2010. The effects of various income averaging policies for mitigating tax penalties are then examined.     

制度和政策不确定性下的创新决策与经济增长过程

构建"2+1"部门内生创新模型,考量政策的连续性和制度的稳定性对经济增长产生影响.结果表明:由于创新活动具有极大的风险性质,初期需要巨大投入,而回报分散在漫长的未来时间,因而未来面临的各种制度和政策变化都会影响到创新成果的现值,从而不利于鼓励研发部门将资源投入创新活动.更重要的是,由于政府部门需要实现多重政策目标,这意味着鼓励创新的目标可能受到牵制,从而增加了创新活动未来收益的不确定性.因此,要促进创新活动,必须为研发部门提供一个可以稳定预期的未来制度与政策环境.     

Can employee ownership and human resource management policies clash in worker cooperatives? Lessons from a defunct cooperative

The article analyzes the interaction between employee ownership, HRM policies and practices, and HRM outcomes in what was the world's biggest industrial worker cooperative for decades, and now defunct, Fagor Electrodomésticos. Using longitudinal internal data and detailed interviews with key stakeholders, this paper sheds light on how employee ownership conditioned HRM policies. HRM outcomes—such as job satisfaction and absenteeism—are also analyzed over a long period of time. Chronic nepotism when recruiting new members, failures in the training policy, impoverished and Taylorist working systems, and reverse dominance hierarchies are analyzed as factors that increased free riding and caused low satisfaction and the disengagement of working members. This case study contributes to the literature on HRM and worker cooperatives as it provides some insights that are rarely found in that literature. It also provides guidance to worker cooperatives about increasing the fit between employee ownership and HRM policies and outcomes.
