Optimal Income Taxation with Asset Accumulation
نویسندگان
چکیده
Several frictions restrict the government’s ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable 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 observability 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 typically become less progressive when assets are imperfectly observed. We evaluate the effect quantitatively in a model calibrated to U.S. data.

Abstract T he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. Taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state.

متن کاملAnalyzing the Standard Deduction as a Presumptive Tax
Presumptive taxes can be found in the tax system of most developing countries and make sense when the desired tax base is difficult to measure, verify, and monitor. As a substitute for the desired tax base, the presumed tax base is derived from items that can be more readily monitored. Presumed taxes can also be found in developed countries, and examples include fixed depreciation schedules in ...
متن کاملOptimal Income Taxation with a Risky Asset – The Triple Income Tax
We show in a two-period world with endogenous savings and two assets, one of them exhibiting a stochastic return that an interest adjusted income tax is optimal. This tax leaves a safe component of interest income tax free and taxes the excess return with a special tax rate. There is no trade off between risk allocation and efficiency in intertemporal consumption. Both goals are reached. As the...
