Using a bivariate generalized autoregressive conditional heteroskedasticity (GARCH) model, we examine patterns of information flows for China–backed stocks that are cross–listed on exchanges in Hong Kong and New York. Results analyzing the dual–listed stocks indicate significant mutual feedback of information between domestic (Hong Kong) and offshore (New York) markets in terms of pricing and volatility. Stocks listed on the domestic market appear to play a more significant role of information transmission in the pricing process, whereas stocks listed on the offshore market play a bigger role in volatility spillover. 相似文献

Despite the importance of the London markets and the significance of the relationship for market makers, little published research is available on arbitrage between the FTSE‐100 Index futures and the FTSE‐100 European index options contracts. This study uses the put–call–futures parity condition to throw light on the relationship between options and futures written against the FTSE Index. The arbitrage methodology adopted in this study avoids many of the problems that have affected prior research on the relationship between options or futures prices and the underlying index. The problems that arise from nonsynchroneity between options and futures prices are reduced by the matching of options and futures prices within narrow time intervals with time‐stamped transaction data. This study allows for realistic trading and market‐impact costs. The feasibility of strategies such as execute‐and‐hold and early unwinding is examined with both ex‐post and ex‐ante simulation tests that take into consideration possible execution time lags for the arbitrage trade. This study reveals that the occurrence of matched put–call–futures trios exhibits a U‐shaped intraday pattern with a concentration at both open and close, although the magnitude of observed mispricings has no discernible intraday pattern. Ex‐post arbitrage profits for traders facing transaction costs are concentrated in at‐the‐money options. As in other major markets, despite important microstructure differences, opportunities are generally rapidly extinguished in less than 3 min. The results suggest that arbitrage opportunities for traders facing transaction costs are small in number and confirm the efficiency of trading on the London International Financial Futures and Options Exchange. © 2002 John Wiley & Sons, Inc.

Bank Risk, Capitalization, and Operating Efficiency 总被引:1,自引:0,他引:1
A simultaneous equation framework is used to test hypotheses about the interrelationships among bank interest rate and credit risk-taking, capitalization, and operating efficiency. A positive effect of inefficiency on risk-taking was found and supports the moral hazard hypothesis that poor performers are more vulnerable to risk-taking than high performance banking organizations. A positive effect of inefficiency on the level of capital is attributable to regulatory pressure on underperforming institutions. At the same time, firms with more capital are found to operate more efficiently than less well-capitalized banking organizations. A U-shaped relationship is detected between inefficiency and loan growth, indicating that operating efficiency improves at a decreasing rate as loan growth rate increases. This supports the hypothesis that entrenched managers who pursue a growth objective to enhance their own wealth tend to operate inefficiently. 相似文献

What Moves the Mortgage‐Backed Securities Market? 总被引:1,自引:0,他引:1
Using a vector autoregressive model with monthly data from 1988 through 2001, this study investigates the factors that drive the excess returns on a widely followed mortgage-backed securities (MBS) index. We find that eight important economic variables (industrial productions, new home sales, bond horizon premium, bond quality premium, mortgage rate, refinancing proxy, general stock market index and world bond market index) appear to move the excess returns on MBS. Impulse response analysis and variance decomposition further indicate a strong dynamic relationship between MBS excess returns and changes in these economic variables. Additional analysis of Freddie Mac and Fannie Mae MBS also indicates that the risk of the MBS guarantor is an important determinant of the MBS return dynamics after the creation of the Office of Federal Housing Enterprise Oversight. 相似文献

This study uses an event study methodology to examine how the Chinese market reacts to announcements of involvement in corporate social responsibilitY (CSR) by Southern Weekend (a Chinese newspaper)for Chinese firms from 2008 to 2012. Our results show significant and pcsitive market reactions, supporting the instrumental stakeholder theory. We attribute the positive market response to social capital development and real growth options related to the CSR involvement by the Chinese firms. 相似文献

The literature has suggested that earnings and earnings forecasts provide stronger signals than dividends about future performance
of a firm. We test the information effects of simultaneous announcement of earnings and dividends in the Hong Kong market,
distinguished by three interesting features (concentrated family-shareholdings, low corporate transparency, and no tax on
dividends). Our results show significant share price reactions to unexpected earnings and dividend changes, but dividends
appear to play a dominant role over earnings in pricing, a result contrary to findings in the literature. The signaling hypothesis
works primarily for firms with earning increases, while the maturity hypothesis works mainly for firms with earnings declines.

This research examines the relationship between mentoring functions received by employees and their organizational citizenship behavior (OCB), and the moderating effects of perceived quality relationships with mentoring function providers in China. Results of Study 1 from a sample of 385 supervisor-subordinate dyads reveal that role modeling received by protégés positively relates to their OCB, and perceived mentoring relationship quality moderates the association between career support received and protégés' OCB. Moreover, nonprotégés and protégés who receive high levels of overall mentoring functions perform more OCB than protégés who receive low levels of mentoring functions. Results of Study 2 from 258 supervisor-subordinate dyads show that role modeling received by subordinates positively relates to their OCB directed at individuals (OCBI) and at the organization (OCBO) while career support received positively relates to OCBO. Additionally, leader-member exchange moderates the linkages of role modeling with OCBI and OCBO. 相似文献

This paper investigates the effects of population growth and China's entry into the world trading regime on the North and the South. In the absence of the terms of trade effect, population growth reduces the standard of living and causes a decline in welfare. Unilateral trade liberalization of China will worsen the terms of trade for other countries in the South, but will improve those for the North. Thus, population control is an important means to close the gap in per capita income between developing and developed economies. Trade liberalization by developing countries may not necessarily induce income convergence. JEL Classification Number: F1. 相似文献
