Introduction
Overview of Tax Policy in Developing Countries
Roger H. Gordon
Th is volume provides a detailed assessment of the current tax structure
in six developing countries: Argentina, Brazil, India, Kenya, Korea, and
Rus sia. Each of the six case studies lays out the current statutory provi-
sions, how they have evolved over time, the resulting changes in tax rev-
enue, and the key fi 1 Th e scal pressures faced currently looking forward.
volume also includes two overview chapters that reassess the conven-
tional wisdom about the appropriate design of tax policy in developing
countries.
As is seen from Table I.1, these six countries include both some of the
poorest and some of the richest developing countries. As of 2004, per
capita gross domestic product (GDP) in Korea and Rus sia was well over
$10,000, in Argentina and Brazil it was a bit under $4,000, while India’s
per capita income was only $695 and Kenya’s $469.
Populations also diff er dramatically. India’s population is over a billion,
Brazil is the next largest with a population of 182 million, while Korea,
Argentina, and Kenya are all roughly a quarter as large as Brazil. Th e
countries cover all parts of the globe. Th e three largest of these countries
have a federal system of government, while in the remaining three coun-
tries the national government plays a dominant role.
Th e tax systems in these countries, though largely typical of those in
other developing countries, are strikingly at odds with what the public
fi nance literature recommends as the optimal design of a country’s tax
structure. To begin with, the public fi nance literature at least since Mirr-
lees (1971) focuses heavily on the optimal rate structure under the personal
income tax as a means of best trading off ciency consider- equity and effi
ations in the collection of tax revenue. Refl ecting this focus in the aca-
demic literature, the personal income tax is typically the main source of

tax revenue among developed economies.2 As seen in Table I.1, however,
the personal income tax plays little role in any of these six countries. Th e
presumption must be that the countries are not in a position to monitor
enough of the income accruing to each individual to make an income tax
a feasible option.
Th fth of their tax revenue with a ese countries collect a quarter to a fi
value- added tax (VAT), a tax also used heavily by developed countries.
Since the VAT is a proportional tax without any exemptions for the poor,
developed countries tend to supplement this tax with more generous so-
cial safety- net programs. Developing countries, including the six high-
lighted here, do not in the main have equivalent safety- net programs,
