who use US state level data. Bruce et al.
find a mean short-run above equilibrium sales (income) tax elasticity of 1.8 (2.7)and a long-run sales (income) tax elasticity of 0.8 (1.8).3 Evidence on tax revenue elasticities for developing countries is much scarcer.
This owes inpart to the much more limited availability of detailed and reliable data on tax rates in these countries.
In order to characterize possible differences in the fiscal response to the business cycle between developing and industrial countries,
Talvi and Vegh (2005) look at the correlation between tax revenues and HP filtered GDP. They find that the correlation between tax revenues and HP filtered GDP is about 0.53 for developing countries while it is only 0.38 for industrial countries.
Talvi and Vegh conclude that fluctuations in the tax base are much larger in developing countries than in the industrial countries. More recently, Berg et al. (2009)
