Construction and Analyses of Macroeconomic Model including individuals with non-unitary discount rates

我们构建了具有非单一贴现率的个体的宏观经济模型。个体的决策表现出时间的不一致性。因此，我们必须把不同时间的个体视为不同的个体；我们称这些个体为自我。在这个研究项目中，我们已经能够证明存在使所有自我的福利水平最大化的最优消费税税率。此外，我们已经证明，即使在增长模型中，这一性质也成立。

We have constructed macroeconomic model that has individuals with non-unitary discount rates. Decision making of the individuals shows time inconsistency. Thus, we must treat an individual at different times as different individuals; we call these individuals as selves. In this research project, we have been able to show that there exists optimal rate of consumption tax that maximize the welfare levels of all selves. Moreover, we have shown that this property holds even in a growth model.
