The paper compares the way economies with exogenous and endogenous innovation respond to capital income taxes. If innovation is exogenous, tax cuts increase saving. If innovation is endogenous, tax cuts increase innovation as well. Faster innovation raises capital productivity and calls forth...

Although technical knowledge generates spillover benefits, production of technical knowledge creates congestion externalities; thus, private R&D investment could be inefficient. A computable general equilibrium model is used to rank tax incentives by their effects on research effort and measure...

General sales taxes provide substantial fractions of state and local revenues in the US. However, state and local sales tax bases have been eroding steadily during the past 50 years. Base erosion contributes to fiscal stress in the states; therefore, prospects for continued sales tax base...

Previous studies suggest that income taxes do not affect the convergence speed in neoclassical and new growth models. Those studies use very simple tax structures. This paper shows that a relation between taxes and convergence speed emerges if tax benefits are included in standard macroeconomic...

The elasticity of taxable income determines revenue and welfare responses to taxes. Measurement of this elasticity is an ongoing focus of tax policy research. Empirical studies report short-run elasticities. However, general equilibrium relationships can cause short-run and long-run elasticities...

With few exceptions, state and local general sales and use taxes are levied primarily on tangible goods. Secular trends in production and consumption of goods and services, as well as legislated exemptions and exclusions, have eroded sales tax bases. A number of reforms designed to reduce base...
