Board Members and Company Value

This essay surveys research about the value of individual members of boards of directors. When directors join or exit corporate boards, company stock prices respond, often in magnitudes of 1% of firm value or more. Related research shows that when a significant event impacts the stock price of one company, the effects are transmitted to other companies that share board members in common with the primary company. Share price reactions are sensitive to variables such as a director’s occupation, independence, and professional qualifications. Together, this evidence suggests that a well-functioning market for directors might already exist, making direct regulation unnecessary and possibly counter-productive.     

A multilateral approach to examining the comovements among major world equity markets

This study investigates the comovement in stock indices among major developed markets, where Morgan Stanley Capital International (MSCI) indices are employed for the purposes of the study. We employ a model that accommodates multilateral international impacts on equity index movements. The empirical results reveal the existence of significant international transmission effects among these major world markets, both in terms of returns and volatility, and mostly in a positive direction. The U.S. market, as expected, is the leading market in the sense that it has the most pervasive and significant impact on all markets across continents. However, the U.S. market exhibits a different relationship with European markets from that with Asia-Pacific markets. The evidence also suggests that strong regional transmission effects exist. A further investigation using the extended model reveals that the linkages between U.S. and European markets are driven by positive global common forces and by negative international competitive effects. On the other hand, the U.S. and Asian markets are linked through positive global common forces and positive international contagion effects. The United States, Canada, and the U.K. are the three markets that still demonstrate contagion influence over countries outside its own region. The Asia-Pacific markets are more susceptible to contagion effects. Finally, it is interesting to find that Japanese market performance became more contagious toward other markets during the Asian financial crisis period.

政府职能转型与媒介效应述评——以电子政务为例

在由计划经济向市场经济转型过程中,我国政府职能正加速向“服务型”政府转变。适应媒介融合发展的趋势,电子政务在各级政府部门方兴未艾。媒介产业日益融合的今天,电子政务立足于互联网平台,涵盖了微信、微博、各类手机APP等多种媒体形式。完善的电子政务服务有利于提升公众对政府的信任和公共服务的满意度。当前电子政务媒介效应经验评价方法主要有层次分析法（AHP）、结构方程法（SEM）、因子分析和DEA方法,但这些方法在指标体系选择和测评方法的适应性方面还存在不足,努力构建普遍适应的、数据可获取性强的电子政务媒介评价方法体系是今后该领域研究的方向。     

Monetary policy and stock valuation: structural VAR identification and size effects

This paper examines the relationship between the US monetary policy and stock valuation using a structural VAR framework that allows for the simultaneous interaction between the federal funds rate and stock market developments based on the assumption of long-run monetary neutrality. The results confirm a strong, negative and significant monetary policy tightening effect on real stock prices. Furthermore, we provide evidence consistent with a delayed response of small stocks to monetary policy shocks relative to large stocks.     

Liquidity operations during the financial crisis 2008/09: evidence from the relations between Korean won onshore and offshore markets

This paper addresses the interrelation of onshore and offshore markets before and after the Bank of Korea intervened in 2008/09. During the financial crisis, Korea faced a liquidity crunch and leveraged its high level of reserves to conduct swap agreements in late 2008. To analyse how the reforms affected the mean and volatility spillover in between the spot and NDF markets, an extended GARCH model is used. The main findings of this paper are that prior to the financial crisis, the spot market dominated the offshore market. This changed after South Korea addressed the won’s liquidity crunch at the height of the crisis. Mean and volatility spillover between the markets diminished and the price gap narrowed. In addition to the empirical results, the paper also underlines the significance of liquidity and robust capital requirements for central banks.

The negative spillover effect of food crises on restaurant firms: Did Jack in the Box really recover from an E. coli scare?

Despite the enormous impact of food crises on restaurants, limited understanding of their long-term impacts and associated factors has undermined crisis managers’ ability to handle crisis situations effectively. This article investigated the long-term impact of food crises on the financial performance of restaurant firms and identified the factors that influenced this impact. This explanatory study examined the case of Jack in the Box, whose 1993 Escherichia coli scare was the first and largest restaurant-associated food crisis in modern times. An event study method was used to uncover stock price movements of Jack in the Box, in conjunction with 73 unrelated food crises that occurred from 1994 to 2010. Stock prices of Jack in the Box exhibited significantly negative responses to other firms’ food crises, moreover, the negative spillover effect was stronger if the crisis occurred closer in time, was similar in nature, and was accompanied with no recall execution. These findings shed light on the long-term financial impact of food crises and offer insights for crisis managers to develop more effective crisis management strategies.     

国土空间多功能利用效益评价——以广东省汕头市为例

进行汕头市国土空间多功能利用效益评价,为汕头市科学利用土地,进行国土规划、提高国土利用效率奠定前提和基础。以可持续发展为目的,结合汕头市自然社会发展特点及国土空间利用现状,从社会、经济、资源与生态环境4个功能为切入点,建立4个功能层10个准则层27个指标的国土空间多功能利用效益评价指标体系,并采用熵值法对各功能进行评分。研究结果显示:汕头市国土空间经济功能评分最高,为汕头市国土空间主导功能,其次是经济、资源、环境功能,但社会、文化等功能较弱,各功能缺乏平衡。15年来,汕头市国土空间评价总体评分不断提高,表明国土利用效益在持续提高,但各功能发展不均衡以及人地矛盾依然突出,需要不断加强和完善国土空间规划。
