We study implications of habit formation for optimal taxation. First, we show that taxation problems with habit formation can be analyzed using dynamic programming techniques. Second, we derive optimal labor and savings wedges for habit formation preferences. We show that habit formation counteracts the conventional Mirrleesian distortions and calls for subsidies to labor supply and savings. We demonstrate that the theoretical results are quantitatively important: in a stylized life-cycle model, average labor and savings wedges fall by more than one third compared to time-separable references. Third, we exploit the analogy between habit formation and durable consumption to study the taxation of durable and nondurable commodities.

Several frictions restrict the government's ability to tax assets. First, it is very costly to monitor trades on international asset markets. Second, agents can resort to nonobservable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high. This paper shows that limitations in asset taxation have important consequences for the taxation of labor income. We study a simple dynamic moral hazard model of social insurance with observable and nonobservable saving decisions. We find that optimal labor income taxes become less progressive when the ability to tax savings is limited.

This paper shows that limitations in asset taxation have important consequences for the taxation of labor income. Using a dynamic moral hazard model of social insurance, we find that optimal labor income taxes become less progressive when governments face limitations in asset taxation. We evaluate the quantitative effect of imperfect asset taxation for two applications of our model.
