Our paper systematically examines the effects of fiscal structure on e
conomic growth. We find that for developing countries, debt-financed i
ncreases in government expenditure retard growth and tax-financed incr
eases stimulate growth, while for developed countries, debt-financed i
ncreases in government expenditure do not affect growth and tax-financ
ed increases lower growth. We impose the government budget constraint
on the regression equations so that the precise changes in fiscal poli
cy can be identified (e.g., the effect of a debt-financed increase in
health expenditure), employing a pooled cross-section, time-series sam
ple and fixed- and random-effect methods.
