Children’s Consumption of Fruits and Vegetables: Do School Environment and Policies Affect Choice in School Meals?

Ishdorj, Ariun; Crepinsek, Mary Kay; Jensen, Helen H. - Agricultural and Applied Economics Association - AAEA - 2012

Considering most children spend a majority of their weekdays at school and, on average, obtain more than one-third of their daily caloric intake from meals consumed at school during the school year, school is a natural place to implement nutrition policies that would help develop healthy eating...

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...

A SAMPLE SELECTION APPROACH TO CENSORED DEMAND SYSTEMS

Yen, Steven T.; Lin, Biing-Hwan - Agricultural and Applied Economics Association - AAEA - 2004

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...

A NONPARAMETRIC HYPOTHESIS TEST VIA THE BOOTSTRAP RESAMPLING

Temel, Tugrul T. - Agricultural and Applied Economics Association - AAEA - 2001

This paper adapts an already existing nonparametric hypothesis test to the bootstrap framework. The test utilizes the nonparametric kernel regression method to estimate a measure of distance between the models stated under the null hypothesis. The bootstraped version of the test allows to...

Parametric or Nonparametric Approaches to the Estimation of Marginal Cost in Dairy Production? A Comparison of Estimation Results

Wieck, Christine; Heckelei, Thomas - Agricultural and Applied Economics Association - AAEA - 2007

This paper compares various nonparametric models for the estimation of farm specific marginal costs function in the dairy sector. Specifically, locally weighted regression approaches using theory-consistent cost function frameworks as polynomials in the nonparametric approach are applied. A...
