Marginal Income Tax Rates And Economic Growth In Developing Countries

First published in 1978. The tax system is one of the instruments said to be available to translate development policy objectives into practice. The wide-ranging papers collected together in this volume, first published in 1978, explore different aspects of the link between national development objectives and the tax system. Attention is particularly focused on traditional aims such as growth, fair distribution and economic stabilisation and development. Articles written by distinguished experts in the fields of public finance and economic development clarify the concepts of taxable capacity and tax effort, and examine the connections between growth and changes within the tax system.

A review of current thinking on taxation which examines the changes in tax structure occurring in 11 countries, ranging from Indonesia and Mexico to Sweden and the United States. The book coincides with a trend towards tax reform which has taken hold in many developed and developing countries.

Personal Income Tax (PIT) is one of the key sources of revenues in Advanced Economies (AEs) but plays a much more limited role in Low-Income Developing Countries (LIDCs) and Emerging Market Economies (EMEs), both in terms of revenue and redistributive impact. Notwithstanding, this paper shows that LIDCs and EMEs increased their PIT-to-GDP revenue by 110 and 48 percent, respectively, during the 1990-2019 period, a marked improvement in the PIT revenue performance. We find that this rise was driven primarily by economic developments and to a lesser extent by changes in the design of PIT systems. We also find that LIDCs that improved their tax-to-GDP ratios relied on a broader set of tax instruments and not exclusively on the PIT, suggesting that a successful revenue mobilization strategy of developing countries requires a comprehensive approach covering a wider range of taxes. Finally, using a newly assembled dataset of PIT characteristics of 157 countries over the 2006-2018 period, we estimate a novel redistribution index of the PIT in LIDCs. We show that the contribution of the PIT to inequality reductions has been significant.

This paper surveys the theoretical and empirical literature on the relationship between taxation and public expenditure and economic growth. Particular attention is paid to the effect of taxation and government expenditure on the supply and productivity of labor and physical capital. Studies suggest that well-targeted government expenditures on health, education, and infrastructure should have a positive impact on growth. By contrast, the impact of taxation on the supplies of labor and capital, and on output growth, is more muted.

Written by Ved P. Gandhi, Liam P. Ebrill, George A. Mackenzie, Luis Mañas-Antón, Jitendra R. Modi, Somchai Richupan, Fernando Sanchez-Ugarte, and Parthasarathi Shome, this book contains 12 articles. It examines the relevance to developing countries of the tax policy recommendations of supply-side economists and attempts to delineate policy guidelines to ensure that fiscal management enhances rather than inhibits growth and efficiency in the wider economy.

This report investigates how tax structures can best be designed to support GDP per capita growth.
