Tao Sun is a Ph.D. candidate in the Department of Economics at the University of Melbourne. His research focuses on discrete choice modelling and Bayesian nonparametric modelling with applications in demand estimation and health economics. The first chapter of his thesis develops a Bayesian semi-parametric multinomial choice model that flexibly models choice-specific indirect utility by introducing a Bayesian sparse finite mixture model. The new model is then applied to household demand for dairy products to illustrate its applicability. His second chapter studies the illicit and licit drug use with focuses on the substitution/complementarity between substances and the endogeneity issue in the access to illicit drugs, i.e., endogenous choice set.
