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

This study examines the information conveyed by options and examines their implied volatility at the time of the 1997 Hong Kong stock market crash. The author determines the efficiency of implied volatility as a predictor of future volatility by comparing it to other leading indicator candidates. These include volume and open interest of index options and futures, as well as the arbitrage basis of index futures. Using monthly, nonoverlapping data, the study reveals that implied volatility is superior to those variables in forecasting future realized volatility. The study also demonstrates that a simple signal extraction model could have produced useful warning signals prior to periods of extreme volatility. These results indicate that the options market is highly efficient informationally. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:555–574, 2007  相似文献

This paper addresses the question of how technology assessment (TA) can be best integrated in the managment of R&D both at the laboratory and the policy level. The main objective is to present a conceptual framework to situate and evaluate the actual and possible TA infrastructure in Europe. The paper consists of three distinct sections. In section one, the concept and practice of TA are briefly introduced with an emphasis on their actual institutionalizations in Europe. Section two presents a conceptual framework of R&D managment at four levels: the R&D environment, the R&D institution, the R&D process, and the R&D project. The relationship between TA and R&D management is explored for each of the four levels. Finally, in section three the concept of and motives for TA integrated within the laboratory work of scientists and engineers are presented. The basic argument of this paper is that by promoting the integration of TA in R&D managment practices, a significant contribution can be made to (1) increasing the cost-efficiency of research and (2) increase the social responsiblity of scientists. The authors therefore draw up a conceptual framework for the development of R&D-integrated TA practices called Integrated Technology Assessment (ITA).  相似文献

The propensity of the forecasts of sell-side financial analysts to converge (or diverge) is a function of their exogenous and endogenous selective attention and overconfidence. When returns are negative, the endogenous form of selective attention—a static measure of analysts’ goal-driven attention at a particular point in time—has a positive association with convergence. The exogenous form of selective attention—a relatively involuntary dynamic process of exogenous attentional shift driven by external changes in the market over time—is associated with a tendency for forecasts to diverge.  相似文献

We study the profitability of Covered Interest Parity (CIP) arbitrage violations and their relationship with market liquidity and credit risk using a novel and unique dataset of tick-by-tick firm quotes for all financial instruments involved in the arbitrage strategy. The empirical analysis shows that positive CIP arbitrage deviations include a compensation for liquidity and credit risk. Once these risk premia are taken into account, small arbitrage profits only accrue to traders who are able to negotiate low trading costs. The results are robust to stale pricing and the nonsynchronous trading occurring in the markets involved in the arbitrage strategy.  相似文献

This paper studies the use of patent statistics in identifying four aspects of technological structure, namely, the potential knowledge pool, cumulativeness, inter-firm homogeneity in technology levels, and the scope of innovations. The firms are sampled from the chemical (CHEM), the computer (COM) and the electrical and electronic (EE) industries worldwide. Using the proxies defined, we find that (i) the contributions of intra-industry spillover are low, at 12%, 10%, and 9% for the three industries respectively; (ii) they can internalize 15%, 19% and 13% of their previous research efforts respectively; and (iii) a positive relationship between knowledge spillover and technology overlap, and between scope of innovation and number of patents being cited in future.  相似文献

Abstract. We conduct a theoretical investigation into how financial reforms are affecting the long‐run economic performance of the partially reformed Chinese economy. In a model with a dual structure in commodity production and financial repression, allowing the co‐existence of a state banking system and an informal credit market and introducing heterogeneity in the transaction technologies of individuals, we examine the interactions between the state banking system and the informal credit market, and the effects of various measures of financial liberalization on individuals’ optimal portfolio choices and the macroeconomic aggregates.  相似文献

This paper extends the equivalence relationship between risk/return linearity and portfolio efficiency as derived in Roll (1977) to the case where there is differential taxation affecting investors optimal portfolio choice. Following the formulation of Brennan (1970a), the fundamental linearity relationship is derived which raises serious doubts to the testability of the extendedCAPM that accounts for the effect of differential taxation. Finally by aggregating other imperfections as well as differential taxation into a dividend yield constraint, a different version of theCAPM is derived which offers alternative interpretations of the existing empirical results on the subject.  相似文献
