Structural Tax Reforms and Public Spending Efficiency

Working Paper
| News

This working paper, from António Afonso, João Tovar Jalles and Ana Venâncio, evaluates the effects of structural tax reforms on government spending efficiency in a sample of OECD economies over the period 2007-2016. Increases in tax rates result in falling public efficiency, with the negative effect found to be more significant for increases in personal income tax and value added tax. In times of economic expansion, increasing the corporate income tax base and reducing personal income tax rates were found to have a positive impact on public sector efficiency. In recessions, efficiency improves when the personal income tax and value added tax bases increase and the corporate income tax rate increases.
