Differing from Ramsey economic growth model ( 1928), this paper puts environmental quality into utility function, and discusses the effect of environmental management on economic growth as well as the improvement of environmental quality. 与Ramsey(1928)经济增长模型不同,本文在效用函数中引入环境质量,讨论了以政府花费形式的环境管理在经济发展与环境质量改善过程中的作用。
Using Ramsey model based on cost function, we seek for second-best price and variables that influence the price level. 本文以社会福利最大化为理论基础,在成本函数的基础上,采用拉姆齐模型进行次优定价以及探寻变量对拉姆齐定价产生的影响。
