This paper presents and evaluates estimation methods for dynamic nonlinear correlated random effects (CRE) models with unbalanced panels. Accounting for the unbalancedness is crucial in dynamic non-linear models and it cannot be ignored even if the process that produces it is completely at...

We evaluate a program that introduced bilingual education in English and Spanish in primary education in some public schools of the Madrid region in 2004. Under this program students not only study English as a foreign language but also some subjects (at least Science, History and Geography) are...

We study the effects on infant mortality of the introduction in 1995 of a non-contributoryuniversal pension scheme in Nepal known as the Old age Allowance Program. We use crosssectionaldata from the 1996 and 2001 Nepal Demographic and Health Surveys. Following astandard diff-in-diffs approach,...

This article studies the effects of gender and ethnicity on occupational segregation. The traditional approach to this topic measures the two sources of segregation separately. In contrast, we measure the joint effect of gender and ethnicity by applying a multigroup segregation index–the...

In this paper the Kullback-Leibler notion of discrepancy (Kullback and Leibler, 1951) is used to propose a measure of multigroup segregation over a set of organizational units within a multivariate framework. Among the main results of the paper it is established that the Mutual Information index...

Conventional difference-in-differences (DID) methods that are used to estimate the effect of a treatment rely on important identifying assumptions. Identification of the treatment effect in a DID framework requires some assumption relating trends for controls and treated in absence of treatment,...

Using micro data from the Austrian Labor Force Survey, this paper explores how decreases in the gender differential in participation rates together with increasing differentials in the incidence of part-time jobs and stable or rising levels of occupational segregation by gender affect the gender...

The core assumption to identify the treatment effect in difference-in-differences estimators is the so-called Parallel Paths assumption, namely that the average change in outcome for the treated in the absence of treatment equals the average change in outcome for the non-treated. We define a...

Evaluamos un programa que introdujo la educación bilingüe en inglés y castellano en educación primaria en algunos colegios públicos de la Comunidad de Madrid en el año 2004. En este programa, los estudiantes no solo estudian inglés como idioma extranjero, sino que el inglés es la lengua...
