The Office of
Lee Professor of Economics
University of Nevada, Las Vegas
My research primarily sits at the intersection of econometrics and productivity analysis, with a broad range of empirical applications in microeconomics, industrial organization and operations research.
My econometric contributions are mostly in (i) semiparametric estimation and testing techniques for data with spatial dependence and (ii) parametric and semiparametric panel data models with (un)observed heterogeneity and selectivity. — In productivity analysis, my research focuses on the methodology for (i) robust measurement of firm productivity and efficiency, (ii) structural identification of production functions, (iii) estimation of the endogenous interplay between firm performance and exporting, foreign investments and cross-peer productivity spillovers, (iv) analysis of firm and market structure in the financial services industry, and (v) modeling of production processes when some outputs are undesirable.
In my work, I have studied the production behavior of firms and the market structure in numerous industries including manufacturing, commercial banking, credit union sector, microfinance, electric power generation and distribution, dairy farming, and others. I have also written on hedonic valuation of adverse effects of non-marketable environmental disamenities and climate change.
I have repeatedly published in many economics and OR/OM journals, including the Review of Economics and Statistics, Journal of Econometrics, Journal of Applied Econometrics, Journal of Environmental Economics and Management, Journal of Banking and Finance, European Journal of Operational Research and Journal of Operations Management. I serve as Associate Editor of Empirical Economics.
