Portrait of Greg Lewis

Greg Lewis

Senior Principal Researcher


I am an economist who works on industrial organization, market design, applied econometrics and machine learning. My work is unified by the twin goals of making better sense of microeconomic data, and using those insights to optimize firm decision making and improve market performance.  My research has spanned a range of industries – online retailing, online advertising, procurement, electricity, education – and has been published in top economics and management journals.
