dc.description.abstractThe efficiency losses from taxation vary directly with the responsiveness of a government's tax bases to tax-rate increases. We estimate the dynamic responses of tax bases to changes in tax rates using aggregate panel data from Canadian provinces over the period 1972 to 2006. Our preferred empirical results indicate that a one percentage point increase in corporate income, personal income, and sales tax rates is associated with a 3.67, 0.76, and 1.17 percent reduction in their respective tax bases in the short run. The corresponding long-run tax base semi-elasticity estimates are higher: -13.60, -3.63, and -3.18, respectively. We use the tax base elasticity estimates to calculate the marginal cost of public funds (MCF) for the provinces' three major taxes. Our computations indicate that the corporate income had the highest MCF and that the sales tax had the lowest MCF in all provinces in 2006. The MCF for the personal income tax ranged from 1.44 in Alberta to 3.81 in Quebec. Our results imply that there would have been significant welfare gains in 2006 from reductions in provincial corporate income tax rates. Our computations also indicate that the equalization grant formula may reduce the perceived MCF of the provinces that receive these grants, and that increases in provincial corporate and personal income taxes can cause significant reductions in federal tax revenues.
