Yves here. This post is the author’s summary of a new working paper Lowering the Marginal Corporate Tax Rate: Why the Debate?, which was a co-winner of the 2015 Amartya Sen Prize Competition given by the Global Justice Program at Yale. It puts another nail in the coffin to the idea that lowering corporate tax rates will boost growth.

Internationally, countries ‘compete’ to attract foreign direct investment (FDI) from multinationals. Despite the increasing evidence of the negative consequences of tax competition, governments continue to base their economic development strategies on it.
The two policy outcomes that are measured when considering tax competition between states are FDI and economic growth.
The assumption has long been that lower corporate taxes lead to increases in FDI, resulting in “capital formation” that generates economic growth. This key assumption is politically attractive because it suggests that the foreign firms link to local production networks and in addition to creating jobs, also provide knowledge transfers that increase the productivity of their local partners.
Site selection firms broker recruitment deals between local governments and foreign investors, gaming the process for their own profit, which they earn based on winning the best incentive package for the global investor. Governments agree to lower and/or eliminate recurrent businesses costs, which are utility and tax rates. A winning bid technically translates into forgone public revenue sources. States lower tax rates, in what many call a ‘race to the bottom.’
Those Falling Tax Rates . . .
The key questions are: what happens over time in this downward-spiralling cycle? And are the benefits of attracting multinational corporations (MNCs) worth the costs of foregone public revenue?
It is this dynamic that I have tracked in my paper, “Lowering the Marginal Corporate Tax Rate: Why the Debate?” It offers a 60-nation analysis of the economic impact of inter-state tax competition over time.
The paper tracks the incentives behind such behaviour in terms of the race-to-the-bottom competition among nations, with a focus on the developing world and its dependence on foreign investment. The paper is an extension of my work on national competitiveness policies published in my 2014 book Policy and Political Theory in Trade Practice: Multinational Corporations and Global Governments (New York: Palgrave Macmillan.) The book tracks how tax competition hurts individual states in the United States. The paper builds on the book’s models, extends the query internationally, and finds that nations that engaged in aggressive tax competition experienced decreased economic growth over time.
The analysis focuses on the main economic indicators that respond to tax incentives, such as MNC mergers and acquisitions, FDI flows, MNC incorporation, internationalization, and global market power.
Looking at data from 1999 to 2009, with the explanation that the first decade of the 2000s ushered unprecedented levels of international economic integration as a result of trade liberalization and globalization policies championed in the 1990s, the study shows that reduced corporate tax rates can increase FDI but over time that increase leads to a negative impact on GDP.
Among the reasons for this paradox is the elusive concept of “capital formation”: a shorthand for genuine wealth creation.
FDI may not create it because today a significant portion of that FDI may be in financial instruments for debt-reducing, tax-deductible write offs, as opposed to operational FDI that generates real economic activity.
This finding relates to the changing nature and fluidity of FDI. Most of it today is not in operational assets, but financial instruments, including debt – so increasing aggregate FDI can actually lead to a loss of tax revenue, if debt and operational assets are treated as tax deductible liabilities. It is this point that politicians miss because of a legacy of economic theory that teaches them that capital and capital formation go hand in hand, and they simply assume that this is the case.
