Using micro-level panel data obtained from a stated preference experiment, we specify a two-sided censoring semi-parametric demand system model with fixed effects. To overcome an estimation difficulty which is potentially a common issue to all applications studying micro-level consumption data, we propose a new consistent two-step estimation framework. The economic restrictions implied by consumption theory are imposed through a consistent and asymptotically efficient GMM estimator. We analyse the consumption behaviour of subjects through estimated expenditure and price elasticities. The partial elasticities of demand with respect to attributes of soft drinks are also examined. 杨欧简介：November 2014-present, Research Fellow（Melbourne Institute of Applied Economic and Social Research），2013 - 2014,Teaching assistant(Monash University, ETC 2410/3440 Introductory Econometrics,ETC 2440 Mathematics for economics and business, ETC 1000 Business and economic statistics) Research Interest：Applied econometrics; Microeconometric models with applications in health economics; Demand system specification and estimation.
