THE OVER-THE-COUNTER MARKET AND NEW YORK STOCK EXCHANGE TRADING HALTS

This paper examines the over-the-counter (OTC) market activities for stocks temporarily suspended by the New York Stock Exchange (NYSE). Unlike previous studies, we use transaction-to-transaction data on the NASDAQ during NYSE trading halts to investigate the price adjustment process between market equilibria. The evidence indicates that while being halted by the NYSE, the same stocks have exhibited significantly greater volatility in the OTC market. Since the volatile price movement is mainly random and provides no arbitraging opportunities for the OTC market traders, we do not find support for the proposal that trading halts should be mandatory for all trading locations.     

Corporate Social Responsibility and Family Business in Spain

Despite the economic relevance and distinctiveness of family firms, little attention has been devoted to researching their nature and functioning. Traditionally, family firms have been associated both to positive and negative features in their relationships with the stakeholders. This can be linked to different orientations toward corporate social responsibility. Thus, this research aims to identify the approaches that Spanish family firms maintain about social responsibility, based on the model developed by Quazi and O Brien Journal of Business Ethics 25, 33–51 (2000). An empirical study carried out for 112 Spanish family firms gives support to our initial assumption about these organizations not being a homogeneous group in terms of their orientation towards corporate social responsibility. The differences in perceptions do not seem to be associated to biographical characteristics. These results lead to some relevant academic and practical implications that suggest interesting lines for future research.María de la Cruz Déniz Déniz is professor in the Department of Management at Las Palmas de Gran Canaria University (Spain).

OVER-REACTIONS IN US AGRICULTURAL COMMODITY PRICES

The purpose of this paper is to test rationality in agricultural commodity markets. We investigate the price-adjustment process after significant events using abnormally large cash commodity price changes as proxies for the arrivals of significant events in the markets. The evidence suggests that market rationality is violated. Generally, agricultural commodity prices tend to reverse after significant events. This is consistent with the over-reaction hypothesis which maintains that traders in spot commodity markets over-weight more recent information and under-weight prior information in their expectations.

Volatility spillovers between the Chinese and world equity markets

We propose measures of the directional volatility spillovers between the Chinese and world equity markets based on Diebold and Yilmaz's (2011b) forecast-error variance decompositions in a generalized vector autoregressive framework. It was found that the US market had dominant volatility impacts on other markets during the subprime mortgage crisis. The other markets were also very volatile, and driven by bad news, their massive volatilities were transmitted back to the US market. The volatility of the Chinese market has had a significantly positive impact on other markets since 2005. The volatility interactions among the markets of China, Hong Kong, and Taiwan were more prominent than those among the Chinese, Western, and other Asian markets were. The major correction of the Chinese stock market between February and July 2007 significantly contributed to the volatility surges of other markets. Owing to the restrictions on foreign investment, the Chinese stock market was not considerably affected in terms of market volatility during the subprime mortgage crisis.     

中国人口结构转变下的保险发展

保险发展和人口发展息息相关,人口结构状况对保险发展有重要影响。在我国人口再生产转变过程中,人口结构发生了较大变化,这种变化必将影响到我国保险业的发展。如何应对人口结构变化的现状与趋势,将是保险发展中不能回避的问题。但是,不同的人口结构,对保险发展的影响不同。文章分析了我国的对保险发展影响明显的相关具体人口结构的变化和趋势,指出我国保险发展必须根据这些变化和趋势,未雨绸缪,积极采取应对措施,并提出了相关的思路。

基于面板数据的中国商业银行效率实证分析

针对以往参数方法存在权重确定困难的问题,本文提出了一种基于面板数据的银行效率评价的非参数方法（BEE）,同时构造了相应的数学模型（M-BEE）。然后,应用（M-BEE）模型对中国四家国有银行、八家股份制商业银行2001-2008年的经济效率状况进行了实证分析,结果表明,八年间中国12家商业银行的综合效率呈现逐年递增趋势,纯技术效率呈现先下降后上升的U型特征,规模效率缓慢上升,变化不显著;2006-2007年我国12家商业银行的综合效率和纯技术效率整体上都有大幅提升;八家股份制银行的综合效率和纯技术效率均明显高于四大国有银行。
