Conditional Cash Transfers (CCT) have gained prominence as impactful interventions aimed at improving education, health, and nutrition in vulnerable populations. Based on evaluations of programs like Oportunidades in Mexico and Familias en Acción in Colombia, we explore the successes and limitations of CCTs over the years. This presentation delves into the positive outcomes seen in rural areas, the challenges of CCT expansions in different contexts, and the importance of program design and evaluation in addressing evolving community needs. New strategies must be considered to ensure future effectiveness.

Evaluating and (Re)-Designing Conditional Cash Transfers Orazio Attanasio (Centre for the Evaluation of Development Policies – EDePo at IFS & UCL) Impact Evaluation Network – Bogotá October 3rd 2007
Introduction • CCT have become extremely important and visible • Since PROGRESA/Oportunidades perceived success CCT have become a model intervention • PROGRESA/ Oportunidades was also a model for the evaluation work that generated. • Oportunidades and some of the other programs have now run for a number of years and are now on the verge of a new phase • There are new challenges ahead: • Design and changes to the program • Evaluation
Introduction • I will use this presentation to talk about some of the results obtained and present some thoughts on the future of these programs • I will use mainly my experience in the evaluation of two programs: Oportunidades in Mexico and Familias en Acción in Colombia
Outline • Results: • Rural areas • Education • Health & Nutrition • Urban Areas • Take up • Other results • Challenges: • Limitations of CCT and changes to CCT programs • Supply interventions? • CCT and social policy in Latin America • Evaluation Challenges Beyond impact evaluation • The long run: • Results? • GE consequences
Results • The evaluation has been crucial to the political success of the program • Randomization is difficult to manage • Design and new modules evaluation work should be informed by the results of the evaluations obtained so far
Results: rural areas • Both in Colombia and in Mexico the results have been quite positive. • Secondary school enrollment: large increases. • Primary school enrollment: small or zero increases. • Health and nutrition: positive effects • Inputs (diet, growth and development check ups, • Height • Occurrence of illnesses • Some limitations: anemia
Results: rural areas • Consumption: • Increases, especially in food • Within food, protein rich commodities • No effects on adult goods • Some saving (investment –see Gertler et al.) • Other effects • Transfers • Social capital? • Migration • Knowledge?
Results urban areas • Mexico: • Low take up • Positive but not as positive as in rural • More ambiguous due to the lack of randomization • Colombia: • Positive in education but not as large • Zero in nutrition and health • Positive in consumption (and some saving)
New challenges: CCT expansions • Different context from rural PROGRESA/ Oportunidades or rural Familias en Acción. • Very poor regions/areas/countries • Africa, or even very marginal regions in LAC • Not so poor regions/areas countries • Urban areas. • Are CCT the right answer in these situations? • And if they are, do they need adjustment?
CCT limitations and new challenges. • Nutrition and early years: • Are we satisfied with the effects? • Anemia • Should we use the CCT to deliver Early Years stimulation? • Should the intervention be adjusted from area to area? • Malnutrition and obesity • Evaluation and design are key! • Oportunidades experiments with Nutrisano, sprinklers. • Delivering Early Years stimulation in marginalized communities.
CCT limitations and new challenges. • Education • The effect on primary school enrolment is often negligible. • (and for a reason) • Enrolment is up: what about learning and academic achievement? • Tertiary education is the big challenge, especially in urban areas? • What role do credit constraint play? • What about the quality of education? • Design and evaluation are key! • Bogotá experiment
Supply interventions • Effects have been shown to be very heterogeneous. • Are there heterogeneous effects driven by the availability of health and education services supply? • What is the quality of these services? • What are the bottlenecks?
CCT politics and social policies in Latin America • CCT and populism. • Brazil • Colombia • Mexico • CCT should not be burdened with many other aims and objectives • Operation difficulties • Transparency and accountability • The political economy of evaluation
Evaluation Challenges: beyond impact effects • Rigorous evaluations have been instrumental to the political success of the programs and their continuation • It should be instrumental to the design of changes to the programs • Experimental and quasi-experimental methods have played an important role • But it is necessary to understand the mechanisms behind the impacts observed in the evaluation
An example • Changes to the structure to the grant • Increase in the secondary school grant and reduction or elimination of the primary school grant • (but what is the effect of the primary school grant on nutritional outcomes at early ages?) • We need structural models: • Todd and Wolpin (2002, forthcoming AER) • Attanasio, Meghir and Santiago (2002)
Other changes to the program • New modules: • Nutrition • Cognitive development • Education
Results: the long run • Next to nothing is known • The analysis is difficult • … and yet these results are crucial for any cost benefit analysis. • GE effects.
Conclusions • CCT have been the most exciting piece of news in Social Policy • The risk is that they are seen as a ‘silver bullet’ that can work in all sort of situations. • … and that one neglects the new challenges ahead: • New modules (nutrition, early year stimulation). • Supply interventions • Integration with other policies (Chile Solidario, Red Juntos in Colombia). • Evaluation has a key role to play in helping to shape the new generation of CCTs and maintaining them independent from the executive.
