I. INTRODUCTION
Most of the world's income tax systems impose tax on the worldwide income of
their residents and on profits with a source in the country where the income is
derived by a non-resident. In the event of cross-border investments or business
activities, two jurisdictions may wish to tax the same profits: the source country
because the income is attributable to factors within that country and the residence
country because all residents are taxed on their worldwide incomes. In the absence
of any agreement between the source country and the residence country of the
cross-border investor or business operator, the source country would have primary
taxing rights if only because it is in a position to extract the tax before the profits
are repatriated to the residence country. Unless the residence country wished to
double tax the income and in effect discourage any outward investment or business
activities by its residents, it will have no choice but to forgo its claimed taxing
rights and limit its tax to the difference, if any, between a lower tax rate imposed
in the source country and a higher rate imposed in the residence country.
Wealthier countries, particularly OECD nations, very often enter into treaties
with each other to divide more evenly the taxing rights flowing from their
competing claims to tax the same income. Treaties limit the source country's
taxing rights, leaving more room for the country in which the investor or business
is resident to tax the profits. Where two capital exporting nations enter into a tax
treaty, the limitation of the source country's taxing rights has little overall impact
if they enjoy roughly equal cross-border investment from one another. If one party
to a treaty is a capital importing nation, a treaty would shift overall taxing rights
(and tax revenue) from the poorer country to the richer country.1 Many African
