Conditional Cash Transfers in Education: Design Features, Peer and Sibling Effects: Evidence from a Randomized Experiment in Colombia
(2008) Barrera-Osorio, Felipe; Bertrand, Marianne; Linden, Leigh L.; Perez-Calle, Francisco
We evaluate multiple variants of a commonly used intervention to boost education in developing countries -- the conditional cash transfer (CCT) -- with a student level randomization that allows us to generate intra-family and peer-network variation. We test three treatments: a basic CCT treatment based on school attendance, a savings treatment that postpones a bulk of the cash transfer due to good attendance to just before children have to reenroll, and a tertiary treatment where some of the transfers are conditional on students' graduation and tertiary enrollment rather than attendance. On average, the combined incentives increase attendance, pass rates, enrollment, graduation rates, and matriculation to tertiary institutions. Changing the timing of the payments does not change attendance rates relative to the basic treatment but does significantly increase enrollment rates at both the secondary and tertiary levels. Incentives for graduation and matriculation are particularly effective, increasing attendance and enrollment at secondary and tertiary levels more than the basic treatment. We find some evidence that the subsidies can cause a reallocation of responsibilities within the household. Siblings (particularly sisters) of treated students work more and attend school less than students in families that received no treatment. We also find that indirect peer influences are relatively strong in attendance decisions with the average magnitude similar to that of the direct effect.
Short-run Learning Dynamics under a Test-based Accountability System: Evidence from Pakistan
(2010) Barrera-Osorio, Felipe; Raju, Dhushyanth
Low student learning is a common finding in much of the developing world. This paper uses a relatively unique dataset of five semiannual rounds of standardized test data to characterize and explain the short-term changes in student learning. The data are collected as part of the quality assurance system for a public-private partnership program that offers public subsidies conditional on minimum learning levels to low-cost private schools in Pakistan. Apart from a large positive distributional shift in learning between the first two test rounds, the learning distributions over test rounds show little progress. Schools are ejected from the program if they fail to achieve a minimum pass rate in the test in two consecutive attempts, making the test high stakes. Sharp regression discontinuity estimates show that the threat of program exit on schools that barely failed the test for the first time induces large learning gains. The large change in learning between the first two test rounds is likely attributable to this accountability pressure given that a large share of new program entrants failed in the first test round. Schools also qualify for substantial annual teacher bonuses if they achieve a minimum score in a composite measure of student test participation and mean test score. Sharp regression discontinuity estimates do not show that the prospect of future teacher bonus rewards induces learning gains for schools that barely did not qualify for the bonus.
The Use and Misuse of Computers in Education: Evidence from a Randomized Experiment in Colombia
(2009) Barrera-Osorio, Felipe; Linden, Leigh L.
This paper presents the evaluation of the program Computers for Education. The program aims to integrate computers, donated by the private sector, into the teaching of language in public schools. The authors conduct a two-year randomized evaluation of the program using a sample of 97 schools and 5,201 children. Overall, the program seems to have had little effect on students' test scores and other outcomes. These results are consistent across grade levels, subjects, and gender. The main reason for these results seems to be the failure to incorporate the computers into the educational process. Although the program increased the number of computers in the treatment schools and provided training to the teachers on how to use the computers in their classrooms, surveys of both teachers and students suggest that teachers did not incorporate the computers into their curriculum.
Using the Oaxaca-Blinder Decomposition Technique to Analyze Learning Outcomes Changes over Time: An Application to Indonesia’s Results in PISA Mathematics
(2011) Barrera-Osorio, Felipe; Garcia-Moreno, Vincente; Patrinos, Harry Anthony; Porta, Emilio
The Oaxaca-Blinder technique was originally used in labor economics to decompose earnings gaps and to estimate the level of discrimination. It has been applied since in other social issues, including education, where it can be used to assess how much of a gap is due to differences in characteristics (explained variation) and how much is due to policy or system changes (unexplained variation). The authors apply the decomposition technique in an effort to analyze the increase in Indonesia’s score in PISA mathematics. Between 2003 and 2006, Indonesia’s score increased by 30 points, or 0.3 of a standard deviation. The test score increase is assessed in relation to family, student, school and institutional characteristics. The gap over time is decomposed into its constituent components based on the estimation of cognitive achievement production functions. The decomposition results suggest that almost the entire test score increase is explained by the returns to characteristics, mostly related to student age. However, the authors find that the adequate supply of teachers also plays a role in test score changes.
Improving the Design of Conditional Transfer Programs: Evidence from a Randomized Education Experiment in Colombia
(2011) Barrera-Osorio, Felipe; Bertrand, Marianne; Linden, Leigh L.; Perez-Calle, Francisco
Using a student level randomization, we compare three education-based conditional cash transfers designs: a standard design, a design where part of the monthly transfers are postponed until children have to re-enroll in school, and a design that lowers the reward for attendance but incentivizes graduation and tertiary enrollment. The two nonstandard designs significantly increase enrollment rates at both the secondary and tertiary levels while delivering the same attendance gains as the standard design. Postponing some of the attendance transfers to the time of re-enrollment appears particularly effective for the most at-risk children.
Evaluating Public Per-Student Subsidies to Low-Cost Private Schools: Regression-Discontinuity Evidence from Pakistan
(2011) Barrera-Osorio, Felipe; Raju, Dhushyanth
This study estimates the causal effects of a public per-student subsidy program targeted at low-cost private schools in Pakistan on student enrollment and schooling inputs. Program entry is ultimately conditional on achieving a minimum stipulated student pass rate (cutoff) in a standardized academic test. This mechanism for treatment assignment allows the application of regression-discontinuity (RD) methods to estimate program impacts at the cutoff. Data on two rounds of entry test takers (phase 3 and phase 4) are used. Modeling the entry process of phase-4 test takers as a sharp RD design, the authors find evidence of large positive impacts on the number of students, teachers, classrooms, and blackboards. Modeling the entry process of phase-3 test takers as a partially-fuzzy RD design given treatment crossovers, they do not find evidence of significant program impacts on outcomes of interest. The latter finding is likely due to weak identification arising from a small jump in the probability of treatment at the cutoff.
The impact of private provision of public education: Empirical evidence from Bogota's concession schools
(2006) Barrera-Osorio, Felipe
In 1999, the city of Bogotá, Colombia launched the Concession School program designed to broaden the coverage and quality of basic education. It consists of a contract between a group of private schools and the public educational system such that private agents provide education for low-income students. This paper tests three main hypotheses concerning the impact of concessions on the quality of education: first, dropout rates are lower in concession schools than in similar public schools; second, other public schools nearby the concession schools have lower dropout rates in comparison with other public schools outside the area of influence; third, test scores from concession schools are higher than scores in similar public schools. The paper presents evidence in favor of the three hypotheses, using propensity score and matching estimators.
