But the uncer- tainties may be converted to additional value to the projects in the case of flexible management. Given the flexibility of project management, this paper extends the classical real options model to a multi-factor model which contains oil price, geology, and engineering uncertainties. It then gives an application example of the new model to evaluate deepwater oil and gas projects with a numerical analytical method. Compared with other methods and models, this multi-factor real options model contains more project information. It reflects the potential value deriving not only from oil price variation but also from geology and engi- neering uncertainties, which provides more accurate and reliable valuation information for decision makers.展开更多

The deep research on private investment in urban and rural human capital in Guangxi is necessary for developing economy and narrowing urban-rural gap. Through the analysis on the historic statistics, it is found that there were disparities total quantity and investment structure of private investment in human capital of urban and rural residents. By using the ELES model, the marginal investment trend, investment demand, elastic income, own-price elasticity and mutual-price elasticity of private investment in human capital of urban and rural residents are analyzed. It is pointed out that income is the key factor that affects the private investment in human capital of urban and rural residents. In Guangxi, the private investment and marginal investment in human capital of urban and township residents are higher than that of rural residents;the own-price elasticity and mutual price elasticity of rural residents' private investment in human capital are all higher than that of urban residents'.展开更多

The news impact curve of copper future price fluctuation respectively introduced funds speculation position and arbitrage position was given, and the result is consistent with the empirical study conclusion. The results show that investment funds are not the factor that causes copper future price fluctuation, but can reduce the copper future price fluctuation; the copper future price fluctuation is more sensitive to negative information, and ftmd speculative positions can reduce asymmetric effect of copper price fluctuation, while fimds arbitrage position influences less.展开更多
