One of the most recent applications of GP to finance is to use genetic programming to derive option pricing formulas. Earlier studies take the Black–Scholes model as the true model and use the artificial data generated by it to train and to test GP. The aim of this paper is to provide some initial evidence of the empirical relevance of GP to option pricing. By using the real data from S&P 500 index options, we train and test our GP by distinguishing the case in-the-money from the case out-of-the-money. Unlike most empirical studies, we do not evaluate the performance of GP in terms of its pricing accuracy. Instead, the derived GP tree is compared with the Black–Scholes model in its capability to hedge. To do so, a notion of tracking error is taken as the performance measure. Based on the post-sample performance, it is found that in approximately 20% of the 97 test paths GP has a lower tracking error than the Black–Scholes formula. We further compare our result with the ones obtained by radial basis functions and multilayer perceptrons and one-stage GP. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Nearly since the first automobile traveled on U.S. soil, questions about how best to compensate people injured by their use have been raised. As early as in 1932, in fact, the tort system of imposing costs on negligent drivers was strongly criticized, and a system of compensation without regard to negligence recommended. Yet despite various efforts to identify and implement improved systems during the past more than 70 years, no clear best compensation mechanism has been found. Current discussions have focused on the “choice” system, under which insureds are allowed to select either a tort system or a no‐fault system of compensation at the time of insurance purchase. New Jersey and Pennsylvania, which implemented very similar choice programs in 1989 and 1990, respectively, offer an opportunity to observe the effects of choice on outcomes such as: use of attorneys, speed of payment, and consistency (equity) of payment. Our results indicate outcomes consistent with expectations in New Jersey (NJ), which switched from no‐fault to choice, but inconsistent with expectations in Pennsylvania (PA), which switched from tort to choice. Furthermore, analysis of tort versus no‐fault selectors postchoice in New Jersey and Pennsylvania does not offer clear evidence of no‐fault's lower administrative costs and speedier, more equitable payment in these jurisdictions. 相似文献

The hotel business is highly sensitive to economic cycles, as the industry faces high frequency and high fluctuation of uncertainty over the demand for lodging services. Without a thorough consideration on the issue, hotels may undergo a business crisis. This research therefore investigates the influence of demand uncertainty on hotel failure by using the operation data of international tourist hotels in Taiwan during 1995–2008. The analysis applies two stages of estimation. The first stage employs a first-order autoregressive model, AR(1), to model lodging demand uncertainty. The second stage estimates the likelihood of hotels’ failure by using a logit model. The results are supportive to determine that the demand uncertainty causes hotel failures. 相似文献

The purpose of this study threefold: to determine whether a shared cultural model of the importance of a set of leisure activities to a good leisure life existed in urban Taiwan, the degree to which cultural consonance in leisure mediates the relationship between leisure constraints and leisure satisfaction, and the degree to which leisure satisfaction affects life satisfaction and self-rated health. Results indicate that a cultural model of the importance of leisure activities to a good leisure life existed among sample members. Second, higher levels of self-reported participation in leisure activities that are culturally agreed upon as more important for a good leisure life are more strongly associated with leisure satisfaction than are activities culturally agreed upon as less important. Finally, leisure satisfaction strongly predicts both life satisfaction and self-rated health. 相似文献

Based on a study of researchers in three major R&D industries in Taiwan, this article found that while both supportive and directive styles of management are important in the supervision of R&D processes, the supportive behavior seems to be more effective than the directive strategy in motivating research professionals at work. Data also indicated that the job characteristics of R&D may be significantly influenced by industrial conditions. The management differences between industries are explained in the features peculiar to each particular industry. Implications of the findings for enhancing the management effect are also discussed.The author is an Associate Professor, Department of Business Administration, National Cheng-Kung University, Tainan, Taiwan, R.O.C.

Venture capital in China: Past,present, and future 总被引:2,自引:6,他引:2
This article reviews the literature on venture capital in China and examines where China’s venture capital industry has been
and where it is likely to go in the future. Since the 1980s, venture capital in China has grown steadily alongside the robust
national economy. The future is likely to offer even greater opportunities, as entrepreneurs are encouraged and property rights
improve. However, there will also be a period of transition as the market continues to mature and as new legal structures
and commercial arrangements emerge. Venture capital in China has many interesting differences from that in Western countries.
The venture capital industry is shaped by the institutional context and China is no exception to this. This article also examines
some specific differences between the system in China and that of the United States. Future prospects for venture capital
are also appraised as China continues its transition to a market economy.

High technology industries employ higher than average numbers of scientists and engineers when compared to the employment of the same group among all industries. Since these jobs require high levels of skills to undertake creative, cutting edge activities, it is anticipated that employment in these industries will be largely based on the levels of human capital of individuals or merit. This study compares how changes in levels of educational attainment affect employment in science and engineering jobs in high technology industries with those outside for four racial and ethnic groups. Although blacks and Hispanics are under-represented in science and engineering occupations, the study finds that the effects of education vary with the level of education, race/ethnicity, and the industry/occupational group under consideration in ways that suggest that the race/ethnicity of an individual still plays an important role in determining employment. 相似文献

This article proposes a novel valuation model, growth and value hybrid model, to estimate the stock price. This proposed model combines the essence of the asset-based approach, the income-based approach, and the principle of mean reversion to develop the theoretical closed-form formula consisting of three coefficients: value coefficient, value support coefficient and growth coefficient. Regression analysis is employed to fit market data to determine these coefficients. Moreover, this study proposes the double sorting method to build the quantile regression models of the formula to estimate the stock price at a specific quantile. The results show that the predictive capability of the hybrid valuation model is superior to the model without using value support coefficient, which supports the assumption that the PBR is not associated with the ROE when the ROE is less than a threshold. In different time periods of the stock market, no significant difference exists on the value support coefficient. However, the variations of the value coefficient and the growth coefficient are significant. 相似文献

This work presents a novel neural network model for forecasting option prices using past volatilities and other options market factors. Out of different approaches to estimating volatility in the option pricing model, this study uses backpropagation neural network to forecast prices for Taiwanese stock index options. The ability to develop accurate forecasts of grey prediction volatility enables practitioners to establish an appropriate hedging strategy at in-the-money option. 相似文献
