Poisoning the mind: Arsenic contamination of drinking water wells and children's educational achievement in rural Bangladesh

Bangladesh has experienced the largest mass poisoning of a population in history owing to contamination of groundwater with naturally occurring inorganic arsenic. Prolonged drinking of such water risks development of diseases and therefore has implications for children's cognitive and psychological development. This study examines the effect of arsenic contamination of tubewells, the primary source of drinking water at home, on the learning outcome of school-going children in rural Bangladesh using recent nationally representative data on secondary school children. We unambiguously find a negative and statistically significant correlation between mathematics scores and arsenic-contaminated drinking tubewells at home, net of the child's socio-economic status, parental background and school specific unobserved correlates of learning. Similar correlations are found for an alternative measure of student achievement and subjective well-being (i.e. self-reported measure of life satisfaction), of the student. We conclude by discussing the policy implication of our findings in the context of the current debate over the adverse effect of arsenic poisoning on children.     

A qualitative inquiry of doctoral students' herding in education and validation of ‘herding in educational decisions’ scale

Fresh PhD recipients are experiencing restricted career opportunities yet the enrolment of PhD Scholars is increasing rapidly. Perhaps, doctoral students lack conscious educational decision-making. Building on such a perspective of doctoral students' unconscious educational choices, we explored their educational choices throughout their life trajectory. We started with a qualitative inquiry of 18 different PhD scholars in Pakistan. The findings helped us in developing a measure to determine the extent of herding in doctoral students' educational decisions. We ‘benefitted from’ this opportunity and validated the scale in two separate quantitative inquiries for conducting an exploratory factor analysis and confirmatory factor analysis. The study concluded a 3-dimensional scale (consisting of 15-items) for measuring ‘herding in educational decisions’. The study offers certain implications for conscious educational decisions.

Student achievement conditioned upon school selection: Religious and secular secondary school quality in Bangladesh

In this paper we present new evidence on the impact of school characteristics on secondary student achievement using a rich dataset from rural Bangladesh. We deal with a potentially important selectivity issue in the South Asian context: the non-random sorting of children into madrasas (Islamic faith schools). We do so by employing a combination of fixed effects and instrumental variable estimation techniques. Our empirical results do not reveal any difference in test scores between religious and secular schools when selection into secondary school is taken into account. However, we document significant learning deficit by gender and primary school type: girls and graduates of primary madrasas have significantly lower test scores even after controlling for school and classroom-specific unobservable correlates of learning.
