Optimal Lifetime Consumption Paths under Equal Yield Income and Consumption Taxes


  • Roskamp, Karl W


Excess burden of an equal-yield, flat-rate tax is studied with the aid of a dynamic model. An individual seeks a consumption rate which maximizes the discounted utility stream over a finite period of known length. With supply of labor but not of savings fixed, government extracts a given amount of revenue through an income or a consumption tax. Income taxation induces early consumption, taxation of consumption early asset accumulation. The latter is higher under a consumption tax. The intertemporal excess burden is lower with a consumption tax. This finding was confirmed in two special cases.
