Essays in Political Economy: Elections, Public Finance and Service Delivery in South Africa Verena Ernestine Kroth * A thesis submitted to the Department of Government of the London School of Economics and Political Science for the degree of Doctor of Philosophy. London, April 2014. ___________________________ * London School of Economics and Political Science Declaration I certify that the thesis I have presented for examination for the MPhil/PhD degree of the London School of Economics and Political Science is solely my own work other than where I have clearly indicated that it is the work of others (in which case the extent of any work carried out jointly by me and any other person is clearly identified in it). I can confirm that the idea for chapter 2 emerged from my previous study for Master of Public Administration at the London School of Economics and Political Science. Chapter 3 is based on a paper that was written jointly with Joachim Wehner and Valentino Larcinese. I certify that I was responsible for the data collection and spatial analysis. Each of us contributed equally to the data analysis and writing of the paper. The copyright of this thesis rests with the author. Quotation from it is permitted, provided that full acknowledgement is made. This thesis may not be reproduced without the prior written consent of the author. I warrant that this authorization does not, to the best of my belief, infringe the rights of any third party. I can confirm that this thesis was copy edited for conventions of language, spelling, and grammar by Michael Wise. 2 Abstract Who gets what, when and how? Each of the three papers in this thesis makes a distinct contribution to answering this question in the context of the political economy of South Africa. The first paper examines how South Africa’s public financial management system distributes central government funds to its provinces. Using a unique panel dataset comprising all provinces and three elections over the period 1995-2010, I demonstrate that provinces where the national ruling party has higher vote margins receive higher per capita equitable shares in pre-election years. This result suggests that even in a dominant party framework, electoral competition can function as an incentive to implement political budget cycles. The second paper evaluates how the extension of the franchise affected the delivery of electricity to South African households. The dataset combines nightlight satellite imagery, census data and municipal election results, making it possible to exploit the heterogeneity in the share of newly enfranchised voters across nearly 800 municipalities with a difference-in-differences approach. The analysis demonstrates that enfranchisement has a significant positive effect on household electrification. Moreover, the findings show that political parties have a potential mediating role in accounting for service delivery patterns in new democracies. The third paper addresses the problem of measurement in studying public service delivery by examining a novel methodology for combining census-based data with satellite imagery of the world at night. Using cross-national data and South African census data, the paper provides a roadmap for how to navigate limitations and thus make the most of this technological advance in quantitative social science research. 3 Acknowledgments There are many individuals to whom I am very grateful for guidance and support. First and foremost, I would like to thank my supervisor, Joachim Wehner, who inspired me to take on this project and provided invaluable ideas and feedback every step of the way. I would also like to thank my advisor, Valentino Larcinese, for his continued support, and Bob Mattes who provided invaluable guidance during my time at the Democracy in Africa Research Unit at the University of Cape Town. At Harvard University, where I spent the last year of my PhD, I benefited greatly from Jim Alt’s mentorship. The spatial analysis in my thesis was possible thanks to the support from Harvard’s Center for Geographic Analysis and Institute for Quantitative Social Science. The first paper benefitted particularly from discussions with Joachim Wehner, Jim Alt, Albert van Zyl and Robert Cameron. The second paper was co-authored with Joachim Wehner and Valentino Larcinese and we received helpful feedback from Mark Borchers, Robert Cameron, Daniel de Kadt, Torun Dewan, Taryn Dinkelman, Andy Eggers, Steven Friedman, Elliott Green, Dominik Hangartner, Simon Hix, Mareike Kleine, Johannes Lindvall, Brian Min, Ian Osgood, Pablo Querubin, David Soskice, Johannes Urpelainen, and Leonard Wantchekon. The idea for the third paper was inspired by Brian Min and greatly benefitted from written feedback from Anne-Marie Jeannet and Clara Rubincam. For support with data and spatial analysis relevant to all chapters, I wish to extend a special thank you to Simo Goshev at the Harvard-MIT Data Center, Kevin Perry at StatsSA, and Giovanni Zambotti and Stacy Bogan at the Harvard Center for Geographic Analysis. 4 Table of Contents Chapter I Introduction 10 1.1 Investigating the role of political competition as an incentive to redistribute public resources 11 1.2 Emphasizing the institutional environment as a determinant of available policy options 13 1.3 Explaining distributive patterns of public service delivery 15 1.4 Using South Africa as a testing ground for the politics of service delivery 17 1.5 Highlighting the importance of measurement and good data 20 Chapter II Political budget cycles and intergovernmental transfers in a dominant party framework: empirical evidence from South Africa 22 2.1 Introduction 23 2.2 A distributive politics perspective on political budget cycles 26 2.3 Incentive and ability in the South African context 30 2.4 Empirical strategy 40 2.5 Estimation results 47 2.6 Evaluation and further discussion 53 2.7 Conclusion 57 Chapter III A better life for all?
