Tax Me, But Spend Wisely? Sources of Public Finance and Government Accountability Lucie Gadenne∗ June 2015 Abstract Existing evidence suggests that extra grant revenues lead to little improvements in public services in developing countries - but would governments spend tax revenues differently? This paper considers a program that invests in the tax capacity of Brazilian municipalities. Using variations in the timing of program uptake I find that it raises local tax revenues and that the increase in taxes is used to improve both the quantity and quality of municipal education infrastructure. In contrast increases in grants over which municipalities have the same discretion as over taxes have no impact on any measure of local public infrastructure. 1 Introduction The idea that increases in tax revenues go hand in hand with more accountable and efficient public spending is at the heart of interpretations of the emergence of representative governments in the West (North and Weingast, 1989, Lindert, 2003). Whether increasing the capacity to tax of governments in today's developing countries would have a similar effect is an open question. It is also an important one as more public investments in infrastructure are necessary to further the economic development of these countries (Duflo, 2011). ∗University College London and Institute for Fiscal Studies, 30 Gordon Street, WC1H 0AX London, United Kingdom.
