As part of the global economy, agriculture and agribusiness of the State of Idaho have been significantly affected by the structural changes taking place in the food-supply chain. Constantly changing consumer preferences, new technologies, and globalization represent both challenges and opportunities for the food-supply-chain participants. The very diverse agriculture of Idaho provides a favorable market environment for agricultural producers and food companies to become involved in various food-manufacturing activities. This paper focuses on the quantitative evaluation of the economic performance of food-manufacturing industries in Idaho, using U.S. Economic Census data for 1997 and 2002. The results have implications for the strategic decision-making of the food-supply-chain participants and government authorities.
