Manuel Arellano is a Spanish economist specializing in econometrics and empirical microeconomics. Together with Stephen Bond, he developed the Arellano–Bond estimator, a widely used Generalized Method of Moments (GMM) estimator for panel data. This estimator is based on earlier work by John Denis Sargan and Alok Bhargava. RePEc lists the paper about the Arellano–Bond estimator as the most cited article in economics.
Arellano earned his undergraduate degree at Universidad de Barcelona in 1979.
