We examine the measurement of tax expenditures, as well as review issues concerning the classification of tax expenditures generally. We use calculations from NBER's TAXSIM to illustrate some of the problems with the current methodology for estimating tax expenditures. Unlike most previous work...

This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation -- notably, raising revenue, redistributing income, and correcting externalities -- and the mapping between these functions and various...

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

The 2007-2010 recession has imposed significant fiscal hardships on state and local governments. The result has been state deficits and the need to increase state taxes, cut spending, and withdraw funds from state rainy day accounts. The primary cause of state budget "gaps" has been the rise in...

Fiscal foresight---the phenomenon that legislative and implementation lags ensure that private agents receive clear signals about the tax rates they face in the future---is intrinsic to the tax policy process. This paper develops an analytical framework to study the econometric implications of...

Government budget balance forces the endogenous use of distortionary tax instruments" when an exogenous reform is implemented. The aggregate efficiency of such reforms is based" on comparisons of simple summary measures of the Marginal Cost of Funds of the various tariff" or quota changes with...

This paper illustrates how one can use causal effects of a policy change to measure its welfare impact without decomposing them into income and substitution effects. Often, a single causal effect suffices: the impact on government revenue. Because these responses vary with the policy in...

Attempting to shed light on the optimal size of government, economists have analyzed planning problems that specify a set of feasible taxation-spending policies and a social welfare function. The analysis characterizes the optimal policy choice of a planner who knows the welfare achieved by each...

One possible explanation for the difficulty in controlling the budget is that a major component of spending --tax expenditures--receives privileged status. It is treated as tax cuts rather than spending. This paper explores the implications of that classification and illustrates how it can lead...
