We evaluate the persistence of incremental industry, firm-specific, and corporate-parent effects on firm profitability across the food and agribusiness sector and further analyze the persistence within four major sectors: processing, wholesale, retail, and restaurant. Results suggest that industry effects are more persistent than corporate effects across the food and agribusiness sector. Results also suggest the retail supermarket sector has had relatively stable profits due to both industry and firm effects during the time period under study. The results have implications with respect to research and extension programs targeted toward educating producers and management about producer-owned businesses.
