Much recent theoretical and empirical industrial organization and demand research is directly useful in framing and conducting agribusiness research, in particular research on firm strategic decision making. This article discusses selected recent work that applies these models to analysis of firms' branding, product introduction, advertising, and entry/exit strategies. It then turns to applications of such models to analysis of how firm strategy interacts with government regulatory policies in the areas of antitrust, food product safety and quality, and food labeling. © 1992 John Wiley & Sons, Inc.
