(introduction...)
Even if international taxation transferred some funds to
developing countries, they would still need to rely primarily on generating
their own resources. Unfortunately, governments in many of the poorer countries
have seen their revenues eroded. Much of this is due to economic decline. When
business enterprises are producing less, and more people are out of work, there
is less income to tax.
The poorer countries are also generally less successful at tax
collection. Not only do they collect less in absolute terms, but they also
gather less as a proportion of GDP. This is illustrated in figure 2.3, which
shows that high-income countries collect more than twice as much as a proportion
of GDP - and that the gap seems to be widening.
A second difference between richer and poorer countries is in
the source of tax revenues. This is illustrated in figure 2.4. The limited
extent of formal employment in developing countries reduces the potential for
collecting social security contributions or personal income tax. In Bangladesh,
for example, only 0.5 per cent of the population was liable for personal income
tax in 1991. Many developing countries have had to make up for the shortage of
personal taxpayers by focusing direct taxation on larger enterprises,
particularly those involved in mineral
extraction.
