Amit Sen earned his Ph.D. from North Carolina State University in Economics and Statistics (co-major). Amit is a Professor of Economics at Xavier University and currently serves as the Co-Director of the Center for International Business. In this capacity, he oversees the International Business B.S.B.A. program as well as co-ordinates all international study trips for the MBA program. For the 2019-2020 academic year, he has designed study abroad trips to Morocco and Portugal.
Amit teaches courses for the undergraduate business/economics programs (Econometrics, Time Series, and International Business), the Customer Analytics M.S. program (Applied Multivariate Statistics), and the MBA program (Statistics, International Business, Managerial Economics). Amit is also affiliated with the Philosophy, Politics & the Public Honors program and the Modern Languages & International Economics B.A. program at Xavier.
Amit’s research focuses on methodological issues related to unit root testing in univariate time series as well as applied econometrics. Amit’s publications have appeared in the Journal of Business and Economic Statistics, The Econometrics Journal, the Journal of Time Series Analysis, Journal of Statistical Planning and Inference, Computational Statistics & Data Analysis, Economics Letters, Statistics and Probability Letters, Applied Economics, Empirical Economics, Communication in Statistics - Theory and Methods, Communications in Statistics - Simulation and Computation.
