Tax Cuts: The Implications for
Growth and Productivity

ABSTRACT
In current public debates over the allocation of budget surpluses, advocates of
tax cuts typically emphasize a large economic efficiency payoff in the form of
higher rates of long-term economic growth, while social advocates emphasize
equity concerns. This paper reviews the mainstream economic and econometric
literature on the relation between taxes and growth, and pays particular attention
to recent work by the Organisation for Economic Co-operation and Development
(OECD) and the International Monetary Fund. The paper argues that the alleged
negative microeconomic impacts of taxes on work effort, savings, and
investment are not always well founded theoretically and that, even where such
linkages are plausible, the impacts on long-term growth rates are modest.
Furthermore, the mainstream literature indicates that public investment and
social expenditures financed from taxes have positive impacts on growth, which
suggests that any efficiency losses associated with such spending may be more
than counterbalanced by efficiency and not just equity gains.
   The paper shows that there is no significant statistical relationship between
overall tax levels as a share of gross domestic product (GDP) and growth rates of
per capita GDP or productivity for OECD countries in the 1990s, which implies that
tax levels are neutral in efficiency terms. In contrast, higher tax levels are associated,
as expected, with lower levels of after-tax household income inequality.
   The paper concludes that in the choice of a combination of tax and spending
measures as a share of GDP the supposed tradeoff between efficiency and equity
does not exist; that the economic efficiency case for tax cuts is exaggerated; and
that the debate over the roles of tax and spending measures in a long-term
economic  growth strategy needs to be more balanced.

The current debate over the allocation of future federal budget surpluses to tax
and/or spending measures has become highly polarized, not least in terms of the
