He is an elected fellow of the Econometric Society, a fellow of the Journal of Econometrics, and has a Multa Scripsit award from Econometric Theory. He has repeatedly served on committees to determine winners of the Zellner and Aigner awards for best papers in the Journal of Econometrics, and on the American Statistical Association’s Zellner Thesis award committee.
Prof. Lewbel's research is mainly in the areas of micro econometrics and in consumer demand analysis. He has published in most of the top journals in Economics, including ten publications in Econometrica and four in the American Economic Review.

Prof. Lewbel is a very highly rated teacher. His courses consistently get top ratings from students for quality of content and instruction (average rating last three years: 4.7 out of a possible 5).
Apart from economics, Prof. Lewbel has studied the theory and practice of juggling. He wrote a regular column for Jugglers World magazine, and coauthored "The Science of Juggling," in Scientific American, November, 1995, vol. 273, #5, pp. 92-97. He has served as a director and judge of the International Juggler's Association's annual national juggling competitions, and can juggle up to eight balls.
