How many subsidies can cause firms to enter and exit is an interesting question. Different from the existing literature, the option game theory is applied to construct a symmetric duopoly model of investment with entry and exit decisions under uncertainty in this paper. As a result, the relation between entry and exit optimal thresholds and subsidies is shown. Moreover, the equilibrium strategies...
It firstly analyzes effects of price shocks in ECX CER spot market and futures markets applying VAR model and Impulse Response Analysis. The results are found that price shocks of CER spot price with Cholesky one standard deviation innovations to itself and futures prices of Dec09 CER, Dec10 CER, Dec11 CER and Dec12 CER show high positive effects while price shocks of CER futures prices to themselves...
In order to study the U.S. economy development and recovery trend after the financial crisis, we first start from the reasons of financial crisis and then make a qualitative analysis of its impact. Then we use the Institute of Supply Management Manufacturing Index (ISM manufacturing & services index) as a representative of the economy, to have a qualitative analysis of the recovery trend of the...
In recent years, the staff poison accidents as a result of the Metallurgical industry pipeline gas leakage occur frequently, they have caused the enormous losses for people's life and property. One of its important reasons is the people do not really understand the laws of the industry pipeline gas leakage and dispersion, particularly the poisoned injury scope change about gas leakage and dispersion,...
Adopt wavelet decomposition and reconstruction technology to implement return time series denoising process and establish stock index futures margin forecasting model. Filter the original time series and extract hidden periodicity and nonlinearity of the volatility of stock index futures return time series by wavelet decomposition, then adopt GARCH model and Genetic Neural Network model for modeling...
This paper investigates whether the introduction of index future in China market will decrease or increase the volatility of the underlying index. We adopt a modified GARCH (1,1) model in which a dummy variable is included. The empirical results show that the introduction of index future trading will reduce the volatility of spot index in China A share market.
In order to avoid the risk in intellectual innovation, four sorts of ways based on technology system have been advanced. All of them are the way re-adjusting the value on the basis of technology demand, and so the risk control has been well designed.
In order to analyze the risk of the credit card in a systematic way, the probability of certain action and utility function are used in the paper. According to the review of the rapid development of domestic credit card market, the potential risk of the application and the issue of a credit card is discussed. Through the illustration of the consumption using a credit card, the most probable condition...
The pricing of carbon allowance has gained wide attention from practitioners, economists and policy makers in recent years. Our paper constitutes the first exercise to employ nonlinear Granger causality test to examine the role of price discovery through the empirical relationship between EUA/CER spot price and futures price. We conduct our analysis in a comparative way by using both the Granger (1969)'s...
In order to know the classification and stage of Chinese aquatic e-business, this paper uses statistic analysis and qualitative analysis to classify the business model of Chinese aquatic e-business, it points out that Supply-Demand Platform is the main business model at the early stage of Chinese aquatic e-commerce, e-store and e-mall has got initial development with the rise of online shopping. At...
As an important kind of payment tools, the non-financial third-party e-payment platforms (NTEP), have developed rapidly. It also became the difficulty and blind spot of government supervision. First, we described the development of NTEP in China with typical e-payment tools, and analyzed the urgency and problems of supervision. Then we studied main foreign models for references. Finally, we proposed...
In order to obtain and maintain competitive advantages to adapt to the changes of e-business environment, e-commerce enterprise must choose and adjust their niche reasonably. Some optimization principles and strategies of e-commerce enterprise niche are put forward. By introducing niche and business niche, the concept of e-commerce enterprise niche is defined. It means the specific position that e-commerce...
We consider the calculation of present value of some annuities over a period of years in which the rate of interest is a random variable under some restrictions. We aim at the expected value and variance of the present value. In this paper, the special pattern of annuity changes whose payments are of the rainbow is studied and beginning value is given. Meanwhile, we find recursive relationships for...
The development and application of Internet provides public organizations and individuals the access to express their opinions, thereby the focus of governmental management shift to the internet domain from the traditional field in dealing with the public crisis. By combining Agent Technique and Meta-search Engine Technique, the paper analyzes and designs its framework and functional modules of the...
Network text filtering model can be based on the user's own needs , and can effectively solve the problem of information lost through the filtering mechanism to actively select the needed information. This paper does an analysis on network information filtering model structure. It is mainly to design a text information filtering model based on Hownet's semantic dictionary to solve the common problem...
A combination forecasting method based on gene expression programming (GEP) is introduced in this paper. The main idea of this method is that the nonlinear combination forecasting function can be simulated by gene expression programming. Not only the difficulty of constructing the nonlinear combination forecasting function is decreased, but also the prediction precision is improved by the combination...
