摘要:
We first consider a closed model, where households' time discount depends on externality in consumption. We can prove that there is a unique steady state, which is a saddle point. Then we extend the model to a two-country world, and derive the condition on the effects of consumption externality under which there is a unique free trade steady state with saddle-point stability.
