Business Organisations, Party Systems and Tax Composition in Developing Countries: A Comparison between Colombia and Peru.

This paper explores the relationship between socio-political institutions and tax composition in developing countries. It argues that strong business organisations and stable political party systems reduce the uncertainty of fiscal contracts for economic elites. The decrease in uncertainty leads elites to accept a larger share of the tax burden, which governments then collect using progressive tax types more intensively. To illustrate this claim, I provide evidence from a comparative analysis of the Peruvian and the Colombian tax history between 1970 and 2010. [ABSTRACT FROM AUTHOR]
