Tax incentives in an economy with public goods

This study employs a dynamic computable general equilibrium (CGE) model of Ohio to evaluate the effect of a state corporate tax cut. The innovative features of this study are (1) the use of the cost of capital concept, (2) dynamic adjustment mechanisms in factor markets, and (3) incorporation of public goods in the household utility function and firms' production functions. The model results indicate that the stimulatory effects of tax cuts for economic development are muted when effects of public expenditures on the productivity of private capital and the migration of households are taken into account. This is because the reduction in public expenditure due to the tax cut implies (1) lower productivity for private industries and (2) lower levels of labor in-migration during the initial several periods after the policy shock as compared to the pre-policy sequence of equilibria. This study shows that evaluation of tax policy without simultaneously considering the effect of public goods can be misleading.
