Guanxi and professional conduct in China: a management development perspective

This paper explores guanxi within the context of 'ethical' behaviour. It was found that guanxi exerted a strong influence on our sample, with the exception of the necessity to lend money. As well, there appeared to be a significant minority of respondents who would behave unethically to preserve group solidarity. It was suggested that a modified version of the Belcourt et al . 's management development model would be a useful tool in the development of modified coaching processes for use in authoritarian cultures.     

The market value of preventive activities: A contingent-claims approach

We use a contingent-claims approach to determine the market value of preventive investments. We show that the lower the initial probability of accident, the greater is the market value of a reduction in this probability. Besides, at initially low probabilities, ceteris paribus, the market gives a higher value to a reduction in accident probability when aggregate (correlated) catastrophic risks rather than independent ones are involved. The reverse occurs at initially high probabilities.     

The Impact of High Tech Production Techniques on Productivity and Profitability in Selected U.S. Manufacturing Industries

This paper examines the impact of high technology onmultifactor productivity and price-cost margins. Principal components obtained from five technologyvariables are related to multifactor productivityand price-cost margin. A negative and significantrelationship between price-cost margin and hightechnology methods when industry effects areexcluded, becomes insignificant in the industryeffects specification. The price-cost marginequations suggest that prior findings of a negativerelationship between profitability and hightechnology may result from omitting industryeffects. For multifactor productivity, there is apositive impact from high technology regardless ofwhether the specification includes industry effects.     

The bias in time series volatility forecasts

By Jensen's inequality, a model's forecasts of the variance and standard deviation of returns cannot both be unbiased. This study explores the bias in GARCH type model forecasts of the standard deviation of returns, which we argue is the more appropriate volatility measure for most financial applications. For a wide variety of markets, the GARCH, EGARCH, and GJR (or TGARCH) models tend to persistently over‐estimate the standard deviation of returns, whereas the ARLS model of L. Ederington and W. Guan (2005a) does not. Furthermore, the GARCH and GJR forecasts are especially biased following high volatility days, which cause a large jump in forecast volatility, which is rarely fully realized. © 2009 Wiley Periodicals, Inc.

An analysis of members' perspectives of service quality in Hong Kong tourist association membership system

The objectives of the study were (1) to evaluate members' satisfaction and expectation towards the quality of services provided by the HKTA membership system; (2) to identify the performance “gap” between members' satisfaction and expectation in the HKTA membership system; and, (3) to explore the impact of members' satisfaction level in participating in the HKTA membership system. A comprehensive survey was conducted and a Simple Random Sampling plan was used to survey 600 members. It was found that 28 out of 32 attributes had negative performance “gaps.” The likelihood of participating in HKTA activities was dependant on the members' satisfaction in “Increase social awareness,” “Opportunities to liaise with business associates” and “Upgrading staff through training courses.” The implications of the findings were discussed and recommendations were proposed.

Multi-market trading and arbitrage

We measure arbitrage opportunities by comparing the intraday prices and quotes of American Depositary Receipts (ADRs) and other types of cross-listed shares in U.S. markets with synchronous prices of their home-market shares on a currency-adjusted basis for a sample of 506 U.S. cross-listed stocks from 35 different countries. Deviations from price parity average an economically small 4.9 basis points, but they are volatile and can reach large extremes. Price parity deviations and their daily changes are positively related to proxies for holding costs that can impede arbitrage, even after controlling for transactions costs and foreign investment restrictions.
