【Abstract】 Under non expected utility, this paper developed a continuous time stochastic economic growth model with productive government expenditure. By the method of stochastic optimization, the macroeconomic equilibrium was derived. The model was used to analyze the macroeconomic effects of productive volatility, average after tax capital return and income taxation on economy. The expression of optimal income tax rate τ *=1-α was derived.更多还原
