Growing inequality in the developed world has led to calls for increasing countries’ top marginal tax rates. Crucially, the optimal top marginal income tax rate depends on people’s tendency to migrate in response to changes in the tax rate. Changes in tax rates and and tax policy must take into account that increases in income tax rates may compel people to leave a country or state. This paper ...

While recent research has emphasized the desirability of studying effects of changes in marginal tax rates on taxable income, broadly defined, there has been comparatively little analysis of effects of marginal tax rate changes on entrepreneurial entry. This margin is likely to be important both because of the likely greater elasticity of entrepreneurial decisions with respect to tax changes (r...

Tax status, a function of current marginal tax rates and expected future taxable income, is predicted to determine funding policy. Tests of this modified tax benefits view suggest that 1) tax status declines are associated with pension contribution reduct...

The paper studies the dynamic macroeconomic and welfare effects of tax policy in the context of an overlapping-generations model of the Yaari-Blanchard type for a closed economy. The model is extended to allow for endogenous labor supply and three tax instruments—namely, a capital tax, labor income tax, and consumption tax.

We analyze the impact of trade in a differentiated good on environmental policy when there is local and transboundary pollution. In autarky, the (equivalent) pollution tax is set equal to the marginal damage from own emissions. If the strategic policy instrument is a tax, leakage occurs under trade and tends to lower the tax. The net terms of trade effect, due to the exportable and importable v...
