Derived Demand for Cottonseed : Dairy Industry Component AgEcon
Arguello, Priscilla B.; Malaga, Jaime E.; Chidmi, Benaissa; Belasco, Eric J.; Knight, Thomas O.; Lopez, Jose Antonio.
Despite much research on feed grains and oilseeds little is known about the dairy industry's influence on aggregate cottonseed demand. A transcendental logarithmic production model with regional dummy variables is used to estimate the US dairy industry's derived demand for cottonseed meal, corn, alfalfa hay and other grains. Own-price and cross-price elasticities for the US dairy industry are estimated using a marginal approach.

Estimation of a Censored Demand System in Stratified Sampling: An Analysis of Mexican Meat Demand at the Table Cut Level. AgEcon
Lopez, Jose Antonio; Malaga, Jaime E..
Evidence of meat trade in the form of table cuts suggests that consumer preferences and tastes vary across meat cuts. Unlike previous studies, this paper estimates demand elasticities at the table cut level from a Mexican survey of household incomes and expenditures, which is a stratified sample. The study uses the two-step estimation of a censored demand system proposed by Shonkwiler and Yen (1999) but incorporates stratification variables into the estimation procedure. Parameter estimates are reported and its standard errors are approximated by using the bootstrap procedure.

EUROPEAN UNION COTTON DEMAND: AN APPLICATION OF DEMAND SYSTEMS AND PANEL DATA AgEcon
Lopez, Jose Antonio; Malaga, Jaime E..
A demand system approach incorporating demographic variables is used to estimate the European Union cotton demand parameters. The European Union is the largest cotton importer of the world. Accurate estimation of European demand parameters is critical to evaluate world cotton trends and to realistically simulate future market scenarios. Unlike previous studies, this paper reports a research in which demands of the 15 European Union members are not aggregated. Moreover, unlike available estimations, the study does not use mill consumption data but cotton equivalent consumption at home.

Forecast and Simulation Analysis of Mexican Meat Consumption at the Table Cut Level: Impacts on U.S. Exports. AgEcon
Lopez, Jose Antonio; Malaga, Jaime E..
An analysis of current and forecasted Mexican meat consumption and imports is presented at the table cut level of disaggregation. Unlike previous studies, this study uses adult equivalence scales, a price imputation approach, a consistent censored demand system, and estimation techniques from stratified sampling. The results indicate that most Mexican consumption and imports of table cuts of meats grow at different rates. In addition, Mexico seems to be following the U.S. preferences for beef cuts, but it does not seem to be following the U.S. preferences for chicken cuts. The study may help U.S. and Canadian meat exporters in forecasting future exports to Mexico, conducting long-term meat investment decisions, or identifying trends in the consumption of...
