Gender differences on sexual behaviour and school inputs: evidence from Bogota.

This thesis explores the correlation between school factors and the differentiated results on sexual behaviour between boys and girls in Bogota. A school stratified propensity score matching was performed to match each boy of the sample with the most similar girls in individual, household and school characteristics. A regression analysis was performed to estimate the correlation between the five school factors evaluated with four main outcomes: have had sexual intercourse, condom use in the last sexual intercourse, incidence of teenage childbearing and age at first intercourse. Boys - in relation to girls - begin earlier their sexual life, more of them reported have used condom in their last sexual intercourse and have a lower incidence of teenage childbearing. These differences are correlated with have reported the school as main source of knowledge about reproductive health and contraceptive methods, a larger proportion of teachers with a graduate or postgraduate degree, a larger proportion of teachers with a related pedagogy degree and to the average age of teachers in the school. The results suggest that the content of the message about sex that is delivered to girls at school is not complete or accurate and that the competences of the school teachers in charge of this task should be improved to reach equally boys and girls.

On the design of education conditional cash transfer programs and non education outcomes: the case of teenage pregnancy

We investigate the effect of education Conditional Cash Transfer programs (CCTs) on teenage pregnancy. Our main concern is with how the size and sign of the effect may depend on the design of the program. Using a simple model we show that an education CCT that conditions renewal on school performance reduces teenage pregnancy; the program can increase teenage pregnancy if it does not condition on school performance. Then, using an original data base, we estimate the causal impact on teenage pregnancy of two education CCTs implemented in Bogot´a (Subsidio Educativo, SE, and Familias en Acci´on, FA); both programs differ particularly on whether school success is a condition for renewal or not. We show that SE has negative average effect on teenage pregnancy while FA has a null average effect. We also find that SE has either null or no effect for adolescents in all age and grade groups while FA has positive, null or negative effects for adolescents in different age and grade groups. Since SE conditions renewal on school success and FA does not, we can argue that the empirical results are consistent with the predictions of our model and that conditioning renewal of the subsidy on school success crucially determines the effect of the subsidy on teenage pregnancy

School management and sexual behavior of teenagers

This paper asks whether school based management may help reducing risky sexual behavior of teenagers. For this purpose we use student level data from Bogot´a to identify students from Concession School (CS), who are enrolled in public education system with a more school management autonomy at school level, and to compare them with those students at the traditional public education system. We use propensity score matching methods to have a comparable sample between pupils at CS and traditional schools. Our results show that on average the behavior of students from CS do not have a sexual behavior that differs from those in traditional public schools except for boys in CS who have a lower probability of being sexual active. However, there are important differences when heterogeneity is considered. For example we find that CS where girls per boys ratio is higher have lower teenage pregnancy rates than public schools with also high girls per boys ratios. We also find that teachers’ human capital, teacher-pupil ratio or whether school offers sexual education are also related to statistically significant differences between CS and traditional public schools.

Gender differences on sexual behavior and school inputs: evidence from Bogota

This paper explores the correlation between school factors and the differentiated results on sexual behavior between boys and girls in Bogota. A school stratified propensity score matching was per-formed to match each boy of the sample with the most similar girls in individual, household and school characteristics. A regression analysis was performed to estimate the correlation between school factors and the main outcomes, namely sexual status, condom use in last intercourse, teenage childbearing and age at first intercourse. Boys - in relation to girls - begin earlier their sexual life, report larger use of condom and lower incidence of teenage childbearing. These differences are correlated with sex education at school, and teacher’s characteristics age, education level and pedagogy degree. The results suggest that the content of sex education that is delivered to girls at school is not complete or accurate and that teachers play a key role to reduce this gender bias
