  3. It also studies the problem of real option pricing when the underlying assets follow the pure jump poisson, mixed jump - diffusion merton and mean - reversion model, and obtains the price formula or partial differential equation to price and hedge the real option. when the value of real option can not separate from the value of project, or the uncertainties are endogenous to real option holder, it is difficult to pricing the real option by the ways of no - arbitrage. in this paper we present a approach named valuation with comparison, its basic point is to value the project or program with flexibility by means of decision tree analysis ( dta ) and stochastic dynamic programming ( sdp ), and the results are compared with that of non - flexibility, finally,

    當實物期權的價值不能從項目價值中分離出來，或者影響基本資產價格的不確定性內生於期權的持有者時，此時實物期權的價值一般難以直接利用無套利方法得到，本文通過對現有文獻進行歸納，提出一種比較定價法，其基本要點是利用決策樹、動態規劃法或二叉樹模型等技術來確定嵌有柔性的項目或方案的價值，然後將其與沒有柔性的項目或方案進行比較，從而獲得各種柔性的價值，作為這種方法的一個應用，本文研究了柔性勞動合約的設計與定價問題，研究表明，對企業重要員工採用長期勞動合約，而對一般員工採用短期合約可以節約勞動力使用成本。
