Using an optimal taxation model combined with a previously neglected scheme of public provision of private goods, we show that there is an efficiency gain if public provision of selected goods replaces market purchases and that efficiency requires marginal income tax rates to be higher than if...

Nonlinear income taxes and linear commodity taxes are analyzed when people differ with respect to ability, high-skill agents have heterogeneous preferences, and neither individual abilities nor preferences are observable. We characterize pure income tax optima, which may be bunching or...
