Professor Trivedi's current research and teaching interests are in (micro-) econometrics. A central focus of his current research interests is microeconometric modeling, with special reference to health care utilization. He has co-authored the Econometric Society Research Monograph, Regression Analysis of Count Data (Cambridge, 1998), a graduate text Microeconometrics: Methods and Applications (Cambridge, 2005), and, more recently, a new graduate-level applied microeconometrics text, Microeconometrics Using Stata (Stata Press, 2008). He has served as Co-Editor of Econometrics Journal (2000-2007) and on the Editorial Board of the Journal of Applied Econometrics since 1986. Some selected recent journal articles include: "Bayesian Analysis of the Ordered Probit Model with Endogenous Selection", Journal of Econometrics (2008); "Copula Modeling: An Introduction for Practitioners," Foundations and Trends in Econometrics, 2007; "Bayesian Analysis of the Two-Part Model with Endogeneity: Application to Health Care Expenditure," Journal of Applied Econometrics, 2006; "A Specification and Simulated Likelihood Estimation of a Non-normal Treatment-Outcome Model with Selection: Application to Health Care Utilization," Econometrics Journal, 2006; "Using Trivariate Copulas to Model Sample Selection and Treatment Effects: Application to Family Health Care Demand," Journal of Business and Economic Statistics, 2006; "A Private Insurance, Selection, and Health Care Use: A Bayesian Analysis of Roy-type Model," Journal of Business and Economic Statistics, 2006.
