An Evaluation of the Soda Tax with Multivariate Nonparametric Regressions

Belasco, Eric J.; Ghosh, Sujit K.; Chidmi, Benaissa - Agricultural and Applied Economics Association - AAEA - 2010

This research extends past work by Shonkwiler and Yen (1999) by allowing for distributional flexibility and nonlinear responses in the form of established semiparametric and nonparametric regressions. The proposed models are shown to outperform the parametric version typically used in demand...

Semiparametric Estimation of Consumer Demand Systems with Micro Data

Sam, Abdoul G.; Zheng, Yi - Agricultural and Applied Economics Association - AAEA - 2007

This article proposes a semiparametric two-step procedure for estimating a censored consumer demand system with micro data. The semiparametric estimator considered in the first step is suggested by Klein and Spady (1993). This estimator, used as a counterpart of the probit estimator in a...
