Theoretical analysis and empirical measurements of the effects of the Philadelphia income tax

This study develops policy-oriented measures of optimal local taxes and their maxima which take into account the existence of macro multipliers, other taxes, and discounting. It also presents an estimate of the effects of the Philadelphia income tax on employment tax and revenues. An upper bound for the optimal tax rate is suggested. The current tax rate is found to perhaps be above both the optimal and the revenue maximizing (or monopoly) point.
