Macroeconomic Policies, Growth, and Welfare in a Stochastic Economy
构建了一个随机均衡增长模型，研究货币与税收政策如何通过影响税后名义利率来影响资本积累、通胀和福利，并推导出福利最大化的利率目标。
An integrated stochastic equilibrium growth model is constructed and directed to various questions pertaining to monetary and tax policy. Two main issues addressed include (1) the tradeoff between the rate of capital accumulation and inflation in a stochastic environment; and (2) economic welfare and optimal policy making. The key result is that policy variables impact on welfare through their effect on the after-tax nominal interest rate, which therefore serves as an intermediate policy target. The welfare maximizing interest rate target is derived and the author discusses its attainment through appropriate monetary and tax policies. Tradeoffs between policy instruments are also addressed.
