The present paper reports a study on the socio-economic determinants of completed fertility in Mexico. Special attention is given to how socio- economic factors such as religion and ethnic group affect the likelihood of transition from low to high order parities. This methodological approach...

In this paper we investigate whether higher education (HE) produces non-pecuniary returns via a reduction in the consumption of health-damaging substances. In particular, the paper focuses on studying the smoking intensity of British individuals. We use data on current smokers from the 1970...

We focus on the effect of English deficiency on the native-immigrant wage gap for male employees in the UK using the first wave of the UK Household Longitudinal Survey. We show that the wage gap is robust to controls for age, region of residence, educational attainment and ethnicity. However,...

We investigate the extent to which deficiency at English as measured by English as Additional Language (EAL), contribute to the immigrant-native wage gap for female employees in the UK, controlling for covariates. To deal with the endogeneity of EAL and a substantial problem of self-selection...

I report on a study of the socioeconomic determinants of completed fertility in Mexico. An innovative Poisson double-hurdle count model is developed for the analysis. This methodological approach allows low- and high-order parities to be determined by two different data-generating mechanisms and...

This paper presents evidence on the impact of the largest deployment of an OLPC program: Plan Ceibal in Uruguay. Unlike previous work in the field, we have unique data that allow us to know the exact date of laptop delivery for every student in the sample. This gives us the ability to use a...

In this paper, we consider the problem of missing values of a continuous response variable that cannot be assumed to be missing at random. The example considered here is an analysis of pupil's subjective engagement at school using longitudinal survey data, where the engagement score from wave 3...

We focus on the effect of English deficiency on the native-immigrant wage gap for employees in the UK using the first wave of the UK Household Longitudinal Survey (Understanding Society). We show that the wage gap is robust to controls for age, region of residence, educational attainment and...

Using the first wave of the UK Household Longitudinal Survey, we investigate the extent to which deficiency at English as measured by English as Additional Language (EAL), contribute to the immigrant-native wage gap for female employees in the UK, after controlling for age, region of residence,...

We present evidence on the impact on students' math and reading scores of one of the largest deployments of an OLPC program and the only one implemented at a national scale: Plan Ceibal in Uruguay. Unlike previous work in the field, we have unique data that allow us to know the exact date of...
