An extension of the standard neoclassical growth model, demonstrating that the optimal steady-state tax on capital income can be positive, negative, or zero, depending on the level of monopoly profits and the degree to which profits can be taxed.

This paper examines the quantitative relationship between the elasticity of capital-labor substitution and the conditions needed for equilibrium indeterminacy (and belief-driven áuctuations) in a one-sector growth model. Our analysis employs a ínormalizedîversion of the CES production...

This paper examines the quantitative relationship between the elasticity of capital-labor substitution in production and the conditions needed for equilibrium indeterminacy (and belief-driven fluctuations) in a one-sector growth model. With variable capital utilization, the substitution...

This paper examines the quantitative relationship between the elasticity of capital-labor substitution and the conditions needed for equilibrium indeterminacy (and belief-driven fluctuations) in a one-sector neoclassical growth model. Our analysis employs a “normalized” version of the CES...

This paper develops a one-sector real business cycle model in which competitive firms allocate resources for the production of goods, investment in new capital, and maintenance of existing capital. Firms also choose the utilization rate of existing capital. A higher utilization rate leads to...

A demonstration that the assumed structure of taxation can have dramatic effects on economic welfare and on the stability of the steady state in a dynamic general-equilibrium model of optimal fiscal policy. The authors find that household welfare is highest under a structure that includes...

An analysis of various schemes for simplifying the U.S. tax system, which finds that a uniform tax system performs almost as well as a system with separate taxes on labor and capital incomes, provided that a depreciation allowance is maintained.

A demonstration of how an income tax schedule that exhibits a progressivity feature can ensure saddle-path stability in a one-sector, real business-cycle model with sufficient increasing returns in production, thereby shielding the economy against sunspot fluctuations.

The development of a real business cycle model in which government fiscal variables such as tax rates and public expenditures are endogenous. The authors characterize the "optimal" behavior of these policy variables over the business cycle and relate this behavior to movements in private-sector...

We show that the steady-state optimal tax on capital income can be negative, positive, or zero in a neoclassical growth model that allows for imperfectly competitive product markets. The sign of the optimal tax rate depends crucially on (1) the degree of monopoly power, (2) the extent to which...
