The upper
diagram shows the principal factors that have an influence on the budget
deficit and indicates what needs to be done to correct it. But this is not the
full story. The diagram below shows that
cutting public expenditure reduces aggregate demand and increases unemployment. The reduction of
aggregate demand reduces economic activity which has the effect of reducing
tax revenue. In addition, the state has to pay out funds
as there is a need for more unemployment benefit payments. The result of these austerity measures is often the opposite of their intended
purpose: they can increase rather than decrease the budget deficit.
There is
plenty of empiric evidence to show that this has happened time and time again.
For instance, a report from UNCTAD (United Nations Conference on Trade and
Development) found that between 1990 and 2000 in all the cases examined where cutbacks in public
spending and tax increases were used, the fiscal situation did not only not
improve but worsened. Despite such repeated evidence, unfortunately calls for austerity measures continue to be heard.
