The effect of maternal education on infant health: Evidence from an expansion of preschool facilities

Abstract: The aim of this study is to measure the effect of mothers starting school earlier, instead of additional schooling at the end, on health at birth of the next generation. The identification strategy uses a construction program of preschool facilities implemented in Uruguay by the mid 90’s. I exploit variation across regions and over time in the number of facilities built. I find that health at birth as measured by extreme low birth weight and extreme prematurity improves for first-born children of mothers that were exposed to the schooling reform. Also, the likelihood that the birth occurs before the 28th week of gestation is completed, is significantly lower for the entire sample of females exposed to the reform. Maternal education increases preventive care during pregnancy, and reduces fertility.

Explaining the student achievement decline between 2003 and 2012 in Uruguay: Evidence from PISA

Abstract: Despite a substantial increase in government spending in education in recent years, the test results of Uruguayan students have followed a disappointing declining trend. The efforts of the government have been useful to increase secondary school enrollment but the evidence shows that they do not seem to be effective at increasing the skills that students learn while in school. This paper aims to enhance understanding on what is behind the drop in the scores of Uruguayan students in the Program for International Student Assessment (PISA) between 2003 and 2012. With this purpose, the paper is divided in two parts. First, it analyzes whether the decline can be attributed to differences in students’ characteristics or to differences in the way these characteristics have been used throughout the years. Using traditional and more recent decomposition techniques, a decomposition analysis at the mean and at different points of the score distribution is performed. The analysis reveals that the student performance decline in Uruguay can be attributed almost entirely to changes in the returns to students’ characteristics. Moreover, the analysis is useful to suggest candidate causes of the student achievement decline that are worth to explore in a forward causal way. In particular, one of the candidate causes that stems from the decomposition exercise is the variation in instruction time across years. The second part of this paper uses a within-student identification strategy to estimate the effect of instruction time on achievement at two points in time. The finding from the latter analysis is that instruction time is not able to explain the performance drop of Uruguayan students that is evidenced in PISA data.
