A Dynamic Approach to Estimating and Testing Separability in U.S. Demand for Imported and Domestic Meats
TLDR
In this paper, a dynamic model of demand for domestic and imported meats is developed based on the long-run solution to the dynamic model and a test for separability is developed.Abstract:
The paper develops dynamic model of demand for domestic and imported meats and compares the performance of the dynamic model called the general AIDS error correction model (GAECM) with the static linear approximate almost ideal demand system (LA/AIDS) model. A test for separability is developed based on the long-run solution to the dynamic model. The results indicate rejection of the static model in favor of the dynamic model. Homogeneity and symmetry are shown to hold for the dynamic model but are strongly rejected for the static model. Finally, separability between domestic and imported meats is rejected for all models at the 5% level of significance. However, the results of the dynamic model based on the corrected likelihood test with a low p-value (p= 0.038) indicate that rejection of separability is borderline.
Le present article porte sur l'elaboration d'un modele dynamique de la demande de viandes produites au pays et de viandes importees, et compare la performance du modele dynamique appele modele general de correction d'erreur AIDS avec le modele statique LA/AIDS. Un test de separabilite est elabore d'apres la solution a long terme du modele dynamique. Les resultats indiquent le rejet du modele statique en faveur du modele dynamique. L'homogeneite et la symetrie sont valables pour le modele dynamique, mais sont fortement rejetees dans le cas du modele statique. Finalement, la separabilite entre les viandes produites au pays et les viandes importees est rejetee pour tous les modeles a un seuil de signification de 5 p. 100. Cependant, les resultats du modele dynamique, fondes sur la correction du test du rapport des vraisemblances avec une faible valeur p (p = 0,038), indiquent que le rejet de la separabilite se situe a la limite.read more

Analysis of Import Demand for Wooden Beds in the U.S.
TL;DR: In this article, the import demand for wooden beds from the top seven supplying countries was analyzed and the analysis revealed that the antidumping investigation on China has some temporary trade depression effect on China, but trade diversion occurs to Vietnam, Indonesia, Canada, and Brazil.

The trade effect of price risk: a system-wide approach
TL;DR: In this article, risk factors were incorporated into the Almost Ideal Demand System model to explain why the trade effect of risk factors is ambiguous regarding the magnitude and sign of the trade effects.

Demand patterns of rice imports in Malaysia: implications for food security
John Yeong Sheng Tey,Alias Radam +1 more
TL;DR: In this article, the authors analyzed demand patterns of rice imports in Malaysia with an ultimate intention to provide policy implications for its food security, and showed that rice imports will be narrowly sourced, largely from Viet Nam with Thailand second in importance.

Estimating an Almost Ideal Demand System Model for Meats in Iran
TL;DR: In this article, a dynamic form of the almost ideal demand system (AIDS) was employed to determine long-run equilibrium model and represents the short-run dynamics by an error correction mechanism.

An Almost Ideal Demand System
TL;DR: The Almost Ideal Demand System (AIDS) as mentioned in this paper is a first-order approximation of the Rotterdam and translog models, which has been used to test the homogeneity and symmetry restrictions of demand analysis.

Demand for Beef and Chicken Products: Separability and Structural Change
TL;DR: In this article, the authors investigated whether consumers allocate expendi- tures among meats by animal origin or by product type, and did disaggregation of meat into products in a meat demand model give insight into the causes of structural change.

Does Food Safety Information Impact U.S. Meat Demand
TL;DR: In this article, a theoretical model of consumer response to publicized food safety information on meat demand is developed with an empirical application to U.S. meat consumption, and the authors find that the average response to food safety concerns is small, especially in comparison to price effects, and to previous estimates of health related issues.

Dynamic Specification, the Long-Run and The Estimation of Transformed Regression Models
TL;DR: In this paper, the authors discuss the best way to formulate and estimate a dynamic econometric model when interest focuses mainly upon its long-run properties, using results derived for the more general context of transformed regression models, and show how point estimates and the standard errors of long run multipliers and long run structural coefficients can be obtained using standard estimation methods.
