摘 要:
本文在一个带有污染的随机内生增长模型中引入了递规效用．证明了在一定的宏观均衡条件下，主要经济指标的均衡值可唯一的决定于模型参数．并证明了许多模型参数对福利和经济增长的影响与跨时替代弹性而不是风险厌恶系数有关．[著者文摘]

Abstract:
In this paper, we introduce recursive utility into a stochastic endogenous growth model with pollution. This paper proves that under appropriate macroeconomic equilibrium conditions,the equilibrium values of the main economic indexes are uniquely determined by the parameters in the model. This paper also proves that the effects of many parameters in the model on the welfare and economic growth are related to the intertemporal elasticity of substitution rather than risk aversion.[著者文摘]
