Does Less Education Harm Health? Evidence From a Natural Experiment in a Developing Country

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We investigate the health outcome effects of a reduction in years of schooling in Egypt in 1988, a policy change that moves in the opposite direction in relation to the extant literature. We exploit this policy change as a natural experiment and employ a fuzzy regression discontinuity design to investigate a range of objectively measured ...

Global sensitivity analysis of integrated assessment models with multivariate outputs

Risk Analysis, EarlyView.
Abstract Risk assessments of complex systems are often supported by quantitative models. The sophistication of these models and the presence of various uncertainties call for systematic robustness and sensitivity analyses. The multivariate nature of their response challenges the use of traditional approaches.

Small‐ and large‐group instruction and a didactic method in mathematics for low‐performing adolescents: results from a randomized field experiment

The Scandinavian Journal of Economics, EarlyView.
Abstract There is an increasing focus on helping low‐performing adolescents in school. We have randomly exposed low‐performing adolescents in mathematics in grade 8 to variations in key school inputs: teacher training, teaching material, and group size.

Statistical disaggregation—A Monte Carlo approach for imputation under constraints

Scandinavian Journal of Statistics, EarlyView.
Abstract Equality‐constrained models naturally arise in problems in which the measurements are taken at different levels of resolution. The challenge in this setting is that the models usually induce a joint distribution which is intractable. Resorting to instead sampling from the joint distribution by means of a Monte Carlo approach is also ...
