FOREIGN AID, CHILD HEALTH, AND HEALTH SYSTEM DEVELOPMENT IN TANZANIA AND UGANDA, 1995-2009 by Kevin Croke July 2011 Baltimore, Maryland A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy © 2011 Kevin Croke All Rights Reserved Abstract As donors have scaled up efforts to improve health in sub-Saharan African, African countries have diverged sharply in their health performance: Some countries have made rapid progress while others have stagnated. Yet the reasons for these divergences are often not well understood. In this dissertation I present in-depth case studies of two such divergent countries, Tanzania and Uganda, over the 1995-2007 period. Over this period, Tanzania reduced its under-5 mortality rate by 35%, while Uganda’s mortality rate decline was less than half as rapid; between 12% and 15% over virtually the same period. This occurred despite the fact that both countries received similar amounts of foreign aid for health, implemented virtually identical health sector reforms, and saw comparable rates of growth in GDP per capita and similar trends in other socioeconomic indicators. Explanations for such differences often vary by academic discipline. Public health scholars often focus on coverage levels of critical child health interventions, while political scientists emphasize variation in the quality of governance institutions. I show that coverage of child survival interventions did indeed differ between Tanzania and Uganda, particularly in the area of malaria control, but that the ultimate determinant of these differences can be traced to political economy factors. Specifically, regime maintenance dynamics and the differing composition of political patronage coalitions in the two countries determined the relative success of health sector programming in Tanzania and Uganda. ii In addition to outcomes such as under-5 mortality, I also analyze the results of broader health system strengthening efforts in Tanzania and Uganda over the 1995-2009 period. To structure this comparison, a new theoretical framework for health system performance is developed and tested, based on previous theory developed by Pritchett and Woolcock (2002) and Fukuyama (2004). The same political economy dynamics that contributed to Tanzania’s stronger performance on child mortality reduction also enabled its greater progress on health system strengthening. Furthermore, Tanzania’s experience demonstrates the potential for “second best” strategies for health system strengthening that can be implemented in conditions of relatively low state capacity.

completed without the help of many people. My dissertation committee played an important role throughout the process. In particular, my primary dissertation advisor Professor Frank Fukuyama has taught me most of what I know about the field of comparative politics, offered wise methodological counsel, and was a source of advice and encouragement from start to finish. Professor Peter Lewis was also a valued advisor, and generously stepped into a larger role when Professor Fukuyama moved to Stanford University in 2009. Dr. Nandini Oomman was a valuable sounding board, and had much wisdom to share on the role of HIV/AIDS programs in Africa. Professors Tanvi Nagpal and Josh Michaud graciously
