Setting the futures margin with price limits: the case for single-stock futures

Price limits are artificial boundaries established by regulators to establish the maximum price movement permitted in a single day. We propose using a new censoring method that incorporates the effect of price limits on the futures price distribution and investigates how to set an appropriate daily margin level using single-stock futures in Taiwan. We compare our estimations with those obtained using the method in Longin (J Bus 69:383–408, 1999). The results show that (1) the margin levels derived from the Longin method, which ignore price limits in the estimation, are lower than those in our censoring method; and (2) the legal margin for single-stock futures set at 13.5 % by the Taiwan Futures Exchange to avoid default risk appears to be too high.     

Good deeds earn chits? Evidence from philanthropic family controlled firms

This study examines whether charitable family controlled firms have lower default risk. Using Taiwan data that provide clear information about firms’ benevolent intention and avoid endogeneity issue of risk and charitable activities, we show that charitable family controlled firms have lower default risk, which is proxied by value-at-risk and expected shortfall measures. Our finding shows that charitable activities bring benefits of lower risk to shareholders. This study also provides various channels that can lower default risk for the charitable firms. That is, these firms appear to have higher credit ratings, engage less in earnings management, and have higher worker productivity. This study argues that the benevolent mindset of decision makers at firms help lower default risk.     

Evidence on the dynamic relationship between international trade and the stock market

This study uses vector autoregressive analysis to examine the dynamic interactions of monthly real stock returns, return volatility, exchange rates, export growth and import growth for Hong Kong, Korea, Singapore, and Taiwan for the period 1975–91. We find that exports and imports have significant interactions. The results also indicate that stock returns in Hong Kong and Singapore Granger-cause trade flows. Return volatility is found to react strongly to trade news in all four countries, a result supporting the efficient-market hypothesis.     

A Citation Analysis of Business Ethics Research: A Global Perspective

The paper documents the post-war retrenchment and failure of the post-war British Consumer Co-operative Movement. In contrast to the general failure one CEO, Terry Thomas stands out both for his success in co-operative rebranding and returning to profitability the UK Co-operative Bank and because he alone amongst the top echelons of the Co-operative Groups Management based his strategies on a clearly articulated philosophy based on his understanding of the values and purpose of the co-operative movement rooted in its historical traditions grounded in the writings and achievements of Robert Owen, The paper goes on to provide a case study of the bank’s process of transformation from loss-making subsidiary to the first positive co-operative national brand in the post-war period of its history. The author argues that lack of appropriate vision based on the founding values and purposes of the Co-operative Movement is the principal reason for the management’s and governance failures that have beset the UK Co-operative Group. Instead of using the past to help in understanding the present and planning for the future, the UK Co-operative Group Leadership ignored it or worse used the past successes to congratulate itself and disguise its manifest failures. In this, they were supported by an uncritical Co-operative Union (later renamed Co-operatives UK). Davis argues large co-operatives cannot be managed by a civil service responsible to an elected board. Co-operatives need a servant-leadership model of professional management dedicated to the transformational goals set by the founders of the co-operative movement. This needs a radical rethink and promotion of co-operative management education and a dedicated executive recruitment that seeks out value-based professionals whose attitudes and values are compatible with Co-operative values, ownership and purpose.     

Effects of Social Capital,Top Executive Attributes and R＆D on Firm Value in Chinese Small and Medium-sized Enterprises

This study uses an unbalanced panel data analysis to examine the effects of social capital, top executive attributes and R ＆D on firm value in Chinese small and medium-sized enterprises （SMEs） listed on the Shenzhen Stock Exchange Small and Medium-sized Enterprises Board from 2007 to 2011. There are several interesting findings. First, the gender （male） and academic degree of the chairperson in the SMEs have a positive and significant effect on firm value. Second, social capital （measured by politieal connections, managerial business association networks and technology association networks） and R＆D have a positive effect on SME firm value. Third, the effect of politieal connections on firm value for state-owned enterprises （SOEs） is stronger than for non-SOEs, while the effect of business and technology networks on firm value for non-SOEs is stronger than for SOEs. Our study has important policy implications for SMEs that want to compete successfully in China.     

Growth Enterprise Board Initial Public Offerings： Characteristics,Volatility and the Initial-day Performance

We use the Chinese initial public offering data from October 2009 to August 2010 to examine the newly‐established growth enterprise board (GEB). The results indicate that the GEB has been successful and is providing a viable channel for new small and medium‐sized firms to raise external capital. Four variables, the volatility variable, the turnover ratio, the winning lottery ratio and the price–earnings ratio, are important factors driving the initial‐day returns in the regression analysis. The implementation of the new trading‐halts policy on the GEB is found to be effective in mitigating excessive speculation. Our analysis results could be used by policy‐makers to gauge the effects of policy changes on the underpricing of the initial public offerings of the GEB.
