Consistent aggregation assures that behavioral properties, which apply to disaggregate relationships also, apply to aggregate relationships. The agricultural economics literature is reviewed which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to...

The generalized composite commodity theorem (Lewbel 1996) is used to test for consistent aggregation of U.S. and Mexican agricultural production data in each of the categories for which earlier tests rejected homothetic separability. All U.S. agricultural outputs can be justifiably aggregated...

Consistent aggregation ensures that behavioural properties which apply to disaggregate relationships apply also to aggregate relationships. The agricultural economics literature which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to aggregation...

The increased prevalence of childhood obesity is a major concern for society. Thisstudy aims at exploring the influence of the parents (especially parental time allocationchoices) on children’s obesity-related health outcomes and examining the potentialdifferences between the...

In recent years, increasing attention has turned toward the effect of health information or health knowledge on nutrient intake. In determining the effect of health information on nutrient demand, researchers face the estimation problem of dealing with the endogeneity of health information...

The USDA recently redirected the Market Access Program (MAP) to allocate all branded products export promotion funds to small firms and cooperatives. The redirection was, in part, a response to reports by the General Accounting Office that were critical of past allocations of export promotion...

The current obesity crisis in the United States is generating numerous alternative policy options for combating the problem. One alternative that has been widely proposed is an excise or sales tax on sugar-sweetened non-alcoholic beverages. This literature started out within a very simple...

The increased prevalence of childhood obesity is a major concern for society. This study aims at exploring the influence of the parents (especially parental time allocation choices) on children’s obesity-related health outcomes and examining the potential differences between the fathers’ and...

In the estimation of aggregate meat demand systems, weak separability is often a maintained assumption. However, only a few studies have tested and failed to reject this assumption. Recently, Lewbel (1996) developed a generalized composite commodity theorem (GCCT) that is less restrictive than...
