In this paper, an optimal rule is adopted to guild the timing of high technology product to the market, this idea is illustrated through the theory of optimal stopping, and a high approach is developed to theoretical framework for timing decision. On this basis, a random programming model is established, in which the objective function is the expected profit to adopt high technology and the constraint condition is the successful probability over critical value a with all variables beyond the rule, and it is used to find the optimal timing of adopt high technology product.展开更多

We obtain different investment decision with different amount of firms engaging in the R&D and each firm's expected profit respectively. When the risk (the probability each firm succeed) is not random, it's socially desirable to have more firm engaging in R&D if and only if the relationship among the invest cost, the probability and the prize satisfies some condition, that is, Eπ s(n)≥Eπ s(n-1)I≤α(1-α) n-1 V . When the R&D cost I is certain, more prizes or higher probability will make more firms engage in the R&D and higher prize makes it's socially desirable to have more firm invest in R&D.展开更多

文摘In a symmetrical static game model, this paper is mainly concerned with the research and development (R&D) strategy of the High Technology (HT) industry and the society's optimal R&D level given the investment revenue.
