This paper discusses the theory and practice of tax design to achieve an efficient and equitable outcome, i.e. in support of inclusive growth. It starts with a discussion of the key principles from tax theory to guide practical tax design. Then, it elaborates on more granular tax policy, discussing key choices in the structure of the personal income tax on labor and capital income, taxes on wealth, the corporate income tax, and consumption taxes. The paper concludes by highlighting the political economy considerations of the issues with concrete recommedtions as to how to implement tax reform.

There is a growing debate on the relative merits of universal and targeted social assistance transfers in achieving income redistribution objectives. While the benefits of targeting are clear, i.e., a larger poverty impact for a given transfer budget or lower fiscal cost for a given poverty impact, in practice targeting also comes with various costs, including incentive, administrative, social and political costs. The appropriate balance between targeted and universal transfers will therefore depend on how countries decide to trade-off these costs and benefits as well as on the potential for redistribution through taxes. This paper discusses the trade-offs that arise in different country contexts and the potential for strengthening fiscal redistribution in advanced and developing countries, including through expanding transfer coverage and progressive tax financing.

The use of property tax incentives for business by local governments throughout the United States has escalated over the last 50 years. While there is little evidence that these tax incentives are an effective instrument to promote economic development, they cost state and local governments $5 to $10 billion each year in forgone revenue. Three major obstacles can impede the success of property tax incentives as an economic development tool. First, incentives are unlikely to have a significant impact on a firm's profitability since property taxes are a small part of the total costs for most businesses--averaging much less than 1 percent of total costs for the U.S. manufacturing sector. Second, tax breaks are sometimes given to businesses that would have chosen the same location even without the incentives. When this happens, property tax incentives merely deplete the tax base without promoting economic development. Third, widespread use of incentives within a metropolitan area reduces their effectiveness, because when firms can obtain similar tax breaks in most jurisdictions, incentives are less likely to affect business location decisions. This report reviews five types of property tax incentives and examines their characteristics, costs, and effectiveness: property tax abatement programs; tax increment finance; enterprise zones; firm-specific property tax incentives; and property tax exemptions in connection with issuance of industrial development bonds. Alternatives to tax incentives should be considered by policy makers, such as customized job training, labor market intermediaries, and business support services. State and local governments also can pursue a policy of broad-based taxes with low tax rates or adopt split-rate property taxation with lower taxes on buildings than land.State policy makers are in a good position to increase the effectiveness of property tax incentives since they control how local governments use them. For example, states can restrict the use of incentives to certain geographic areas or certain types of facilities; publish information on the use of property tax incentives; conduct studies on their effectiveness; and reduce destructive local tax competition by not reimbursing local governments for revenue they forgo when they award property tax incentives.Local government officials can make wiser use of property tax incentives for business and avoid such incentives when their costs exceed their benefits. Localities should set clear criteria for the types of projects eligible for incentives; limit tax breaks to mobile facilities that export goods or services out of the region; involve tax administrators and other stakeholders in decisions to grant incentives; cooperate on economic development with other jurisdictions in the area; and be clear from the outset that not all businesses that ask for an incentive will receive one.Despite a generally poor record in promoting economic development, property tax incentives continue to be used. The goal is laudable: attracting new businesses to a jurisdiction can increase income or employment, expand the tax base, and revitalize distressed urban areas. In a best case scenario, attracting a large facility can increase worker productivity and draw related firms to the area, creating a positive feedback loop. This report offers recommendations to improve the odds of achieving these economic development goals.

The Theory of Taxation and Public Economics presents a unified conceptual framework for analyzing taxation--the first to be systematically developed in several decades. An original treatment of the subject rather than a textbook synthesis, the book contains new analysis that generates novel results, including some that overturn long-standing conventional wisdom. This fresh approach should change thinking, research, and teaching for decades to come. Building on the work of James Mirrlees, Anthony Atkinson and Joseph Stiglitz, and subsequent researchers, and in the spirit of classics by A. C. Pigou, William Vickrey, and Richard Musgrave, this book steps back from particular lines of inquiry to consider the field as a whole, including the relationships among different fiscal instruments. Louis Kaplow puts forward a framework that makes it possible to rigorously examine both distributive and distortionary effects of particular policies despite their complex interactions with others. To do so, various reforms--ranging from commodity or estate and gift taxation to regulation and public goods provision--are combined with a distributively offsetting adjustment to the income tax. The resulting distribution-neutral reform package holds much constant while leaving in play the distinctive effects of the policy instrument under consideration. By applying this common methodology to disparate subjects, The Theory of Taxation and Public Economics produces significant cross-fertilization and yields solutions to previously intractable problems.
