Three Sides of Harberger Triangles

Harberger triangles are used to calculate the efficiency costs of taxes, government regulations, monopolistic practices, and various other market distortions. This paper considers the historical development of Harberger triangles, the associated theoretical controversies, and the contribution of Harberger triangles to subsequent empirical work and theories of market imperfections. Prior to the publication of Arnold Harberger's papers, economists very rarely estimated deadweight losses. The empirical deadweight loss literature expanded greatly since the 1960s now quite common. Meanwhile, critical evaluation of deadweight loss estimates led to new theories of rent-seeking and other inefficiencies of economies with multiple distortions.

Taxes, Technology Transfer, and the R&D Activities of Multinational Firms

Multinational firms that use domestic technologies in foreign locations are required to pay royalties from foreign users to domestic owners. Foreign governments often tax these royalty payments. High royalty tax rates raise the cost of imported technologies. This paper examines the effect of royalty taxes on the local R&D intensities for foreign affiliates of multinational corporations, looking both at foreign-owned affiliates in the United States and at American-owned affiliates in other countries. The results indicate that higher royalty taxes are associated with greater R&D intensity on the part of affiliates, suggesting that local R&D is a substitute for imported technology.

Do Tax Havens Flourish?

Tax haven countries offer foreign investors low tax rates and other tax features designed to attract investment and thereby stimulate economic activity. Major tax havens have less than one percent of the world's population (outside the United States), and 2.3 percent of world GDP, but host 5.7 percent of the foreign employment and 8.4 percent of foreign property, plant and equipment of American firms. Per capita real GDP in tax haven countries grew at an average annual rate of 3.3 percent between 1982 and 1999, which compares favorably to the world average of 1.4 percent. Tax haven governments appear to be adequately funded, with an average 25 percent ratio of government to GDP that exceeds the 20 percent ratio for the world as a whole, though the small populations and relative affluence of these countries would normally be associated with even larger governments. Whether the economic prosperity of tax haven countries comes at the expense of higher tax countries is unclear, though recent research suggests that tax haven activity stimulates investment in nearby high-tax countries.

Taxing Consumption and Other Sins

Throughout American history, the U.S. federal and state governments have imposed excise taxes on commodities such as alcohol and tobacco (and more recently, gasoline and firearms). Rates of such "sin" taxation, and consumption taxation broadly (including sales taxes and value-added taxes), are currently much lower in the United States than they are in Europe, Japan, and other affluent parts of the world. In part, this reflects relative government sizes, but that is not the whole story, since even controlling for total tax collections, levels of national income, government decentralization, and openness to international trade, the United States imposes unusually low excise and consumption taxes. As a result, the United States relies to a much greater degree than other countries on personal and corporate income taxes, thereby affording fewer opportunities to use the tax system to protect individuals and the environment by discouraging the consumption of "sinful" commodities, and instead simply discouraging saving and investment.

On the Timeliness of Tax Reform

This paper analyzes efficient reactions of policy makers to unanticipated tax avoidance. The strategy of many governments is to reform their tax laws and regulations to reduce the effectiveness of elaborate tax avoidance techniques as soon as they are identified. This tax reform process can successfully prevent the widespread use of new tax avoidance strategies, and in that way prevents erosion of the tax base. But it also encourages the rapid development of new tax avoidance techniques by innovators whose competitors are thereby unable to copy their methods -- as a consequence of which, there can be a great premium on being the first to develop and use a new tax avoidance method. An activist reform agenda may therefore divert greater resources into tax avoidance activity, and lead to a faster rate of tax base erosion, than would a less reactive government strategy. Efficient government policy therefore often entails a slow and deliberate pace of tax reform in response to taxpayer innovation.
