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...

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...

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...

Two-stage utility maximization theory has been widely used in the literature to estimate import demand for agricultural commodities that are often inputs. This article examines the overlooked conceptual and empirical limitations of applying two-stage utility maximization theory to model the...

In the past two decades, the profession has expended valuable resources testing structural change in meat demand with mixed results. Overlooked to date is a fundamental methodological problem that transcends all of the methods of testing for structural change. In this study, a formal logic...

An important ongoing debate in the literature is whether or not the relationship between food price per kilocalorie and energy density is real or spurious. No closure has come on this debate because no formal statistical tests have been performed. Rather, the arguments against a real...

Consumers' willingness to pay for natural Christmas tree characteristics are estimated. Differences in willingness to pay for characteristics by specie knowledge and lack of specie knowledge are tested. Differences in willingness to pay for characteristics by specie are also tested. The results...
