This paper evaluates the performance change of the private enterprises listed on China's two exchanges during 2 years before and after listing in the period of 1996-2001. It is concluded that earning ability, real sales and financing are significantly improved, while only profitability decline a little bit after the private firms listed. In addition, we find that IPO private firms have appreciably better performance than that of BS ones as well as the financing condition becomes finer, which is relative to both the attributes of the private enterprises and Chinese regulatory rules. Therefore, we figured out that the outcome of private firms listing is positive, and China's economic reform will be a step-by-step process. 相似文献

This article investigates the extent to which options on theAustralian Stock Price Index can be explained by parametricand nonparametric option pricing techniques. In particular,comparisons are made of out-of-sample option pricing performanceand hedging performance. The dataset differs from many of thoseused previously in the empirical options pricing literaturein that it consists of American options. In addition, a broaderspectrum of techniques are considered: a spline-based nonparametrictechnique is considered in addition to the standard kernel techniques,while the performance of a Heston stochastic volatility modelis also considered. Although some evidence is found of superiorperformance by nonparametric techniques for in-sample pricing,the parametric methods exhibit a markedly better ability toexplain future prices and show superior hedging performance. 相似文献

This paper provides further evidence of price and volume effects associated with index compositional changes by analysing the inclusions (exclusions) from the French CAC40 and SBF120 indices, as well as the FTSE100. I find evidence supporting the price pressure hypothesis associated with index fund rebalancing, but weak or no evidence for the imperfect substitution, liquidity and information hypotheses. The results improve on recent evidence from the S&P500 index. The evidence for the FTSE100 additions shows, in particular, that markets learn about an imminent inclusion and incorporate this information into prices, even before the announcement date. 相似文献

Previous research provides conflicting evidence of the association between the past performance of a business and its competitive
responsiveness, with researchers observing both positive and negative relationships. To clarify this issue, the authors test
a model using survey data from the retailing industry. The model delineates direct and indirect mediated paths through ability
to respond, motivation to respond, and awareness of competitors’ actions to show how past performance can have both positive
and negative influence on competitive responsiveness. However, the overall impact of past performance of an organization on
its competitive responsiveness is positive. The implications of these findings for research, practice, and theory are discussed.

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect. 相似文献
