Speaking in numbers : the effect of reading performance on math performance among immigrants

Isphording, Ingo Eduard; Piopiunik, Marc; … - 2015

This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

Sparse production networks

Bernard, Andrew B.; Zi, Yuan - 2022

Firm-to-firm connections in domestic and international production networks play a fundamental role in economic outcomes. Firm heterogeneity and the sparse nature of firm-to-firm connections implicitly discipline network structure. We find that a large group of well-established statistical...

Econometric methods for causal evaluation of education policies and practices : a non-technical guide

Schlotter, Martin; Schwerdt, Guido; Woessmann, Ludger - 2009

Education policy-makers and practitioners want to know which policies and practices can best achieve their goals. But research that can inform evidence-based policy often requires complex methods to distinguish causation from accidental association. Avoiding econometric jargon and technical...

Partially adaptive econometric methods and vertically integrated majors in the oil and gas industry

Carson, Scott Alan; Al-Sawai, Wael M. - 2023

Regression model error assumptions are essential to estimator properties. Least squares model parameters are consistent and efficient when the underlying error terms are normally distributed but yield inefficient estimators when errors are not normally distributed. Partially adaptive and...

Economies of density, team synergies and unobserved heterogeneity : a study of home care services

Bensaïd, Bernard; Croiset, Solen; Gary-Bobo, Robert - 2022

In the home-care services industry, caregivers drive to visit patients scattered in a district and deliver various care services at the patient's home. We use a unique data set, with a standard panel structure, recording the hours of service and the exact number of miles traveled by each...
