沉没成本约束条件下的最优跨地区投资组合数学分析

An Optimal Investment Portfolios Model Among Different Regions with Investment Sunk Cost

对沉没成本约束条件下的最优跨地区投资组合进行研究,并建立了一个包括商品市场和要素市场在内一般均衡的数学模型.模型的基本函数是S-D-S效用函数和C-D生产函数,这保证了本模型具有良好的可扩展性,并得到独到的结论是的沉没成本对投资的影响要大于利息.

The paper researches the optimal investment portfolios model among different regions with sunk cost. The model is a general equilibrium model including goods and factors market. We use S-D-S utility function and C-D production function, which ensures the model, could he expend to include more variables. The special conclusion in our model is that investment sunk cost makes greater effect on investment than interest.
