Although International Quality Standards 9000 certification is one of the most popular quality assurance systems in the world, its contribution to a firm's value is still a controversial issue. This project re-examines this issue by using stock market reactions to the announcements of the award of certification made by a sample of Hong Kong listed companies, as a proxy for its contribution to a firm's value. The results suggest that on average certification increased a firm's value. However, most of this value increase was incorporated into stock prices before formal announcements were published in newspapers. In addition, the contribution of certification to value was greater in smaller firms than in larger ones. This can be attributed to fewer stock traders and professional analysts following smaller firms. 相似文献

Abstract. In this paper we present a monopolistic competition model that incorporates asymmetric trade barriers and international differences in production costs. The model implies a highly non‐linear bilateral trade equation. Estimation of this equation yields parameters for the elasticity of substitution and trade costs that are more reasonable than those found in previous studies. A simulation indicates that trade liberalization will shift trade from rich countries to poor countries and from within continental trading partners with preferential trade agreements to intercontinental trading partners.

Chinese people have been theorized to be particularly sensitive to social face and avoid direct discussion in conflict to promote interpersonal harmony. Social face has been used to explain the proclivity of East Asians to smooth over conflict. More research is needed to study social face empirically and its relationship with direct discussion and the processes by which social face has its impact. Results from a field interview study and an experiment conducted in China support theorizing that confirmation of face induces cooperative goals and open-mindedness. In contrast with common assumptions about Chinese organizations, direct discussion, compared to avoiding, strengthened relationships. Direct controversy, especially when face was confirmed, induced open-mindedness: Participants asked more questions, explored the opposing views, demonstrated more knowledge of the opposing arguments, and worked to integrate views. These results were interpreted as suggesting that Chinese people can discuss their conflicts directly and cooperatively when they are assured that their face is confirmed. Results have implications both for the general theory of cooperation and competition as well as our understanding of social face in China. 相似文献

The theory articulated in this paper suggests that the desire to reduce demand and competitive uncertainty are two separate, important motives for alliance formation. Taking this as a starting point, we predict the configuration of horizontal alliances that we might expect to observe within an industry when firms experience these uncertainties to different degrees. An empirical test of this theory using data from the global auto industry yields results consistent with the view (1) that alliances are a device for reducing both the uncertainties that arise from unpredictable demand conditions and those that arise from competitive interdependence, and (2) that variation of demand uncertainty and competitive uncertainty across firms explains differentials in both the intensity and structure of their horizontal alliance activity. 相似文献

While conjoint analysis has been applied in a wide variety of different contexts in Marketing, most applications fail to explicitly consider retaliatory reactions from competitors. In this paper, a methodological extension is developed for conjoint analysis by explicitly modeling competition in a game theoretic context. The Nash equilibrium concept is employed to model competitive reactions to produce design, and its implications for reactive product strategies are discussed. The optimal product design problem for each firm is formulated as a nonlinear integer programming problem, which is solved via a specialized branch and bound method combined with a heuristic. In order to compute a Nash equilibrium, a sequential iterative procedure is proposed. The proposed procedure is illustrated under several scenarios of competition using previously published conjoint data.This research has been supported by the Henry Rutgers Research Fellowship, Rutgers University. 相似文献

Price-volume relation in stocks: A multiple time series analysis on the Singapore market 总被引:1,自引:1,他引:0
We examine the price-volume relation in stocks using the multiple time series approach due to Tiao and Box (1981). This approach has the advantage of treating price and volume jointly and symmetrically (without enforcing the roles of input and output). It is free of the simultaneity bias in regression analysis and the unidirectional dynamics imposed by transfer function models. Empirical results show that there is implicit positive correlation between price and volume through their residuals. However, the results for the explicit lead and lag relations are mixed. The technical analysts' adage that volume often leads the trend of price is not supported. Nonetheless, the implicit relationship between price and volume confirms the usefulness of incorporating volume data to forecast future return. Our analysis shows that the multiple time series models outperform the univariate models in post-sample forecasts. 相似文献

无论地下经济还是公开经济都存在税收流失问题.本文采用一定的方法分别对我国1982-2002年间地下经济和公开经济的税收流失规模进行了估测.从税收流失的规模角度看,我国税收的汲取能力比较弱,蕴涵着很大的税收风险.减少税收流失应作为税制改革的重要目标. 相似文献

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time. 相似文献
