In 2018, he became a Founding Fellow of the International Association for Applied Econometrics and was also awarded the Multa Scripsit Award by Econometric Theory in 2012. He has served on the advisory boards of Pacific Economic Review and Singapore Economic Review, and as the Editor of Journal of Econometrics for over two decades.

Professor Hsiao's research interests include theoretical and applied econometrics. He has published extensively in these areas, with numerous research articles in leading journals such as Econometric Theory, Econometrica, Journal of Business and Economic Statistics, Journal of Econometrics, Journal of the American Statistical Association, Journal of Monetary Economics, and Review of Economic Studies, and several books, including Analysis of Panel Data and Panel Data Econometrics.
 

Many micro econometric modeling takes a single equation approach. However, economists typically consider the general (or partial) equilibrium (or coherence) of (a sector of) the economy is achieved through the automatic operation (say, free competition) of the parts that compose the system. We argue that without considering if an equation is identified in the system, the estimation of such an equation could lead to meaningless curve fitting. We review inference methods for a single equation panel endogenous interactive model including the least squares or two stage least squares, profile generalized method of moments (PGMM) or transformed GMM in light of the identification conditions in an interconnected system. Limited Monte Carlos are also conducted to demonstrate finite sample properties of those methods.
