Impact of agricultural policies on caloric consumption

In this article we use an economic model to link markets for agricultural commodities to food-product markets, and to trace the effects of agricultural policies on prices of food products and, consequently, on food consumption and calorie intake. Contrary to common claims, US agricultural policies have had generally modest and mixed effects on prices and quantities of farm commodities, with negligible effects on the prices paid by consumers for food, and thus a negligible influence on dietary patterns and obesity.
