Concentration in animal-based protein industries in the United States continues to garner the interest of policymakers, researchers, and consumers alike. We assess the impacts of industry concentration on animal productivity and downstream prices in the US broiler chicken industry between 1991 and 2019. We compile a dataset that matches annual, plant-level information on ownership and sales for all poultry processing facilities in the United States with market-level wholesale composite prices and bird yields. Consolidation over the last three decades has greatly contributed to industry concentration, leading to higher wholesale composite broiler prices (16.3%) and gains in animal productivity (2.4%).

Key determinants of monthly wholesale prices for 12 beef cuts include the quantity of the specific cut, stickiness in prices, marketing costs, quantities of pork and chicken, and seasonality. Seasonal patterns across the respective cuts are very different. Relative to the price in December, prices at the wholesale level in other months can be as much as 6 percent lower to as much as 21 percent higher.
