This paper firstly examines the international beef market, then the concept of economic surplus and the effects of the collection of additional animal health information on the aggregate beef supply curve. The effects of movements in the beef supply curve on domestic producer and consumer surplus are then determined. In development of the model, the effects of a shift in the supply curve in an unrestricted domestic market are examined. A free international trade model is then developed followed by a model that includes the effects of trade restrictions in the form of quotas.
