The main objective of this paper is to test the hypothesis that consumer preferences for beef in the United States have been affected by structural change, which reduces to testing for parameter stability in estimated demand equations. To this end, alternative specifications of the demand...

This paper analyzes U.S. countervailing import duties aimed at offsetting the effects of a Canadian hog production subsidy. Approximate countervailing duty formulae for two alternative objectives are derived, the permissible range of these duties is illustrated, and empirical evidence is...

The hypothesis of structural change in U.S. meat demand is tested in a four-meat almost ideal demand system with parameters following a gradual switching regression model. The results support the notion that structural change partly explains the observed U.S. meat consumption patterns....

This paper considers the conversion of import quotas into tariffs, as may arise in the current round of General Agreement on Tariffs and Trade (GATT) negotiations, when the internal market of the country imposing the quota is not perfectly competitive. This case is illustrated by the chicken...

Canadian hog producers are eligible for a federal/provincial hog stabilization program which, under certain conditions, makes deficiency payments to producers enrolled in the program. Currently, producers pay premiums of approximately one-third of the cost of the program, whereas federal and...
