Abstract: Conventional wisdom suggests that weekly prices at farm, wholesale, and retail levels should exhibit symmetry. Observation of asymmetrical price movements is submitted as evidence of the existence and use of "market power" at one or more levels of the market. However, application of economic theory of the market clearing process in a well-functioning, competitive live-stock market shows that weekly prices will move asymmetrically. Studies that confirm asymmetric weekly price movements in farm, wholesale, and retail prices of pork demonstrate that these markets are performing as we would expect well functioning, competitive markets to operate. Claims that evidence of asymmetric weekly (or even monthly and quarterly average prices) is not evidence of market power as claimed by the authors of the studies documenting the asymmetry.
