【摘要】 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.更多还原

【Abstract】 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 be expend to include more variables.The special conclusion in our model is that investment sunk cost makes greater effect on investment than interest.更多还原
