Join Jesus Crespo as he explores the world of econometrics through case studies in development economics.

Influential sets are sets of observations that have considerable impact on econometric results.This webinar presents a disciplined and insightful method for assessing the sensitivity of regression-based inference to influential sets. Algorithmic approaches are explored to identify influential sets, discuss interpretation, and assess the sensitivity of earlier studies to these sets. This method is applied to established results in development economics, and show that results are driven by small influential sets. Identifying and analysing these sets can reveal potential omitted variable bias, unobserved heterogeneity, a lack of external validity, and technical limitations of the methodological approach used.

This event is co-organised with the Vienna Institute for International Economic Studies (wiiw) and the Research Centre International Economics (FIW).
