Taxation in Latin America : Reflections on Sustainability and the Balance between Equity and Efficiency

My aim in this paper is simply to explore in an admittedly discursive and preliminary fashion some aspects of the complex balancing act needed to achieve economically and politically sustainable tax systems in Latin America. By a “sustainable” tax system I mean one that is sufficiently congruent with prevailing economic and political factors in a country to persist without the need for repeated major “reforms”. Specifically, my thesis is that one key to achieving a sustainable tax system is to strike the right “balance” between the equity and efficiency aspects of taxation in terms of the equilibrium of political forces. Experience suggests that any state that wishes to both grow and to implement redistributive fiscal policies - whether the aim be much or little redistribution - must first establish an administrable and efficient tax system. At the same time, however, to make such a system politically sustainable, it must be considered “fair” by a majority of the politically relevant population. Essentially, I suggest in these preliminary musings on this complex subject that one reason why many countries in Latin America do not appear to have either an efficient or a fair tax system is essentially because of the very limited scope of this segment of the population, so that the politically relevant “domain” of the fiscal system is considerably smaller than the population as a whole. Some specific suggestions are made in the paper with respect to how both the efficiency and the equity outcomes of Latin American tax systems might be improved. My general conclusion, however, is the perhaps somewhat pessimistic one that a more democratic and sustainable outcome cannot, as it were, be induced by better fiscal institutions. On the contrary, a more encompassing and legitimate state is itself the key ingredient needed for a more balanced and sustainable tax system. Countries with similar economic characteristics in similar economic situations can and do have and sustain very different tax levels and structures, reflecting their different political situations.In a variant of a phrase currently popular in the literature of political economics, when it comes to tax matters, in general “politics rule.”
