Optimal Taxation, Economic Growth and Income Inequality

That there is a trade-off between equityand efficiency (economic growth) is wellknown. Two models have been developed thatlink government spending and taxation toeconomic growth. This paper uses thesemodels to provide estimates of thegrowth-maximizing tax rate. Then, a twoequation structural model is developed andestimated that is used to find thetrade-off rate between economic growth andincome inequality and the growth-maximizinglevel of income inequality for the UnitedStates over the period 1960–1990.
