Lessons from Global Experience for Successful Decentralization ofHealth and Education Services Jean-Paul Faguet Anila Channa London School of Economics Outline • Introduction: The state of knowledge about D • Decentralization’s Effects on Health and Education • Ranking Empirical Rigour • Papers Weak and Strong • Summary of Results • Policy Implications
IntroductionDecentralization is one of the broadest movements and most contentious policy issues in development. • 80% - 100% of countries in the world experimenting with decentralization (World Bank). • At the center of reform throughout Latin America, Asia and Africa; also EU, UK & US. • Scope of authority and resources devolved: Local governments spend 10 - 50% of total revenues (Campbell, 2003)
What is Decentralisation? (Rondinelli, et. al., 1984) Deconcentration gives limited discretion to field agents. Delegation transfers responsibilities to organizations outside the regular bureaucratic structure. Devolution transfers power and resources to subnational units substantially outside CG control. Privatization transfers functions and assets to the private sector.
These are not different forms of the same thing. Fundamentally different institutional arrangements • establish different internal incentives • prompt very different behaviors. This is a conceptual challenge in studying decentralization.
State of Knowledge • Litvack et al. (1998): “One can prove, or disprove, almost any proposition about decentralization by throwing together some set of cases or data” (p.30). • Shah, Thompson and Zou (2004): D sometimes improved, and other times worsened, service delivery, corruption, macroeconomic stability, and growth across a large range of countries. • Treisman (2007): “To date there are almost no solidly established, general empirical findings about the consequences of decentralization” (p.250). Bizarre paradox: After 50 years of policy experimentation and hundreds of studies we still know very little about whether D is a good or bad thing.
Education and Health – Examples • Positive effects on education provision: Galiani, Gertler and Schargrodsky (2008), Eskeland and Filmer (2002), Parry (1997), Barankay and Lockwood (2007). • Positive effects on education and health: Habibi et al. (2007). • Negative effects on health services: Akin, Hutchinson and Strumpf (2005). • Negative effects on education, health, etc: Crook and Sverrisson (1999), Smith (1985), and Solnick (1996).
Education and Health In summary, a large set of positive results re: education and health services are counterbalanced by a fewer but still compelling negative results. Hard to conclude whether reform improves or degrades education and health.
Theory provides a strong rationale Bring government “closer to the people” better public goods, more effective government • Smaller scale facilitates information, participation and accountability Deepens democracy and lowers costs • Local homogeneity vs. national heterogeneity • Counteract centrifugal forces that cause political tensions/violence [Spain, UK]
Why don’t we know more? • Conceptual confusion • What is D? • Where is it implemented? • Non-rigorous empirical basis Qual: Small-N and large-X Quant: Cross country studies make for bad comparisons – too much RHS uncontrolled variation. • Wrong question: “Is D good or bad?”
Contribution of this review Conceptual confusion? Decentralization = Devolution Non-rigorous empirics? Classify evidence by X: theme and Y: quality or rigor of the evidence Clear patterns emerge. Themes • Allocative efficiency (preference-matching) • Technical efficiency • Equity
Rigour Very Strong Studies with strong research designs that clearly identify causal effects and successfully address endogeneity problems. Randomized control trials.
Strong Research that is able to construct a reasonable comparison group and specifically addresses sources of endogeneity: • Panel estimates in a fixed effects model while controlling for more than one socio-economic covariate, and more than one covariate from the health/education production function. Quasi-experimental designs such as DID and IV.
Somewhat Strong Attempts to construct a valid comparison group, but limited success in dealing with endogeneity. Cross-sectional work with matching Panel estimations with random effects or between effects. Difference in differences lacking key identifying assumptions of parallel trends. Weaker IVs and fixed effects with limited covariates.
Weak Findings based on • self-selected populations • no valid comparison group • omitted variable bias and other endogeneity problems. • Most cross-sectional work, especially single country cases.
Rigorous evidence on technical efficiency is favorable. Decentralization improves technical efficiency in education, health and SBM. Stronger methodologies show stronger effects. Decentralization can enhance service delivery outcomes, from student test scores to infant mortality rates. • More studies examine final outcomes, not policy outputs. Outcomes more likely influenced by exogenous factors. • Only a few studies explain the channel through which service delivery improves Limits policy implications for other decentralizers.
Evidence on allocative efficiency in health is negative. Driven by externalities in health sector. Local governments may match local preferences more efficiently while ignoring spillovers This reduces overall welfare. But this is surmountable with conditional transfers, or with decentralizations that retain central control in areas with large externalities. Evidence on allocative efficiency in education is positive, but few in number.
Decentralization Equity is contingent Elite capture is evident but by no means dominant. Conventional wisdom that Decentralization Efficiency Centralization Equity is misleading, at least w.r.t. public goods delivery. Important to understand existing hierarchical social structures, and then design D reforms around them to promote participation, accountability, and strong equalization transfers.
Political accountability and capacity building dominate as preconditions Evidence supports strong political accountability and capacity building as enablers to successful decentralized service delivery.
Policy Implications (i) • Good decentralization should improve technical efficiency in education and health. • Better quality and quantity or services • Better outcomes (e.g. literacy, infant mortality). • Good decentralization will increase allocative efficiency in education. In health too, if D includes conditional transfers and retained central authority in areas with large externalities.
Policy Implications (ii) • Decentralization Efficiency and Centralization Equity misleading w.r.t. public goods delivery. Understand local hierarchical social structures, then design D reforms with participation and strong equalization transfers schemes. • Political accountability and capacity building dominate as preconditions. Decentralize down to lowest levels suited to particular services, s.t. accountability can obtain. Then build capacity there actively and passively.
