Does democracy affect taxation and government spending? Evidence from developing countries

Focusing on developing countries in three geographical areas (South-East Asia, Latin America and European Union), we explore the relation between political variables and tax revenue, public spending and their structure. We build a new dataset for the 1990-2005 period with fiscal, political and socio-economic variables. Since democracy is a complex and multidimensional concept, we measure it using two variables, the political strength of democratic institutions, and the protection of civil liberties. We perform three sets of estimates: (i) cross-country pooled OLS regressions with region fixed effects, (ii) country fixed effects regressions and (iii) region specific regressions with country fixed effects. While the first model delivers some significant correlations between political variables and tax items, when controlling for country fixed effects we find that tax revenue and tax composition are in general not significantly correlated with the strength of democratic institutions and the protection of civil liberties. The only exceptions are indirect, trade and property taxes. A similar result applies to public spending, with the exception of defense expenditure. Overall, our findings cast some doubt on the exact public policy channels through which political institutions affect economic development.
