In this paper we develop a full information maximum likelihood method for the estimation of a joint model for the choice of length of schooling and the corresponding earnings equation. The model for schooling is assumed to be an ordered probit model, whereas the earnings equation is allowed to...

In this paper we develop likelihood based methods for statistical inference in a joint system of equations for the choice of length of schooling and earnings. The model for schooling choice is assumed to be an ordered probit model, whereas the earnings equation contains variables that are...

Good teachers are the backbone of a successful education system. Yet, in developing countries, teachers' content knowledge is often inadequate. This study documents that primary school math teachers in the department of Moraz'an in El Salvador only master 47 percent of the curriculum they teach....

Education is one of the key resources in the fight against poverty. While substantial progress has been made in terms of school enrollment, evidence suggests that educational quality is still alarmingly low in many developing countries. Various explanations have been suggested, but one very...

This study provides novel evidence on the relative effectiveness of computer-assisted learning (CAL) software and traditional teaching. Based on a randomized controlled trial in Salvadoran primary schools, we evaluate three interventions that aim to improve learning outcomes in mathematics: (i)...

Participatory teaching methods have been shown to be more successful than traditional rote learning in high-income countries. It is, however, less clear if they can help address the learning crisis in low- and middle-income countries, where classes tend to be large and teachers have fewer...
