| Beef and pork prices at farm, wholesale and retail are examined for evidence of a dynamic and asymmetric price transmission using an endogenous switching model. Dynamic adjustment means that it take time for prices to adjust to changes in the market. Price transmission is asymmetric if the speed or completeness of price adjustment depends on the direction that the price or a related price is moving. Some of the previous research on price transmission in agricultural markets attempts to use market power abuses as an explanation of price-transmission asymmetry. Other research shows that price transmission asymmetry can arise in competitive markets and that competitive and anti-competitive issues can make prices adjust faster upwards or downwards. By... |

| We estimated a wholesale demand system for beef, pork, lamb, chicken, and turkey using quarterly U.S. data and a dynamic, CBS system (Keller and Van Driel). The CBS system is a differential system, which means that it might be more appropriately applied in those situations where the data have unit roots. If there are unit roots, differencing the data can improve the properties of the estimates. If the data do not have unit roots, differencing the data might harm the properties of the estimates. We tested the specification of the model's error terms using state-space techniques. State-space units allow one to deal with roots on the unit circle without filtering the data (See Durbin and Koopman). The demand system has only four independent error... |

| The paper demonstrates that random coefficient models can be estimated by maximum likelihood if they are specified as generalized least squares models. The paper uses maximum likelihood estimation on a random-coefficient, meat-demand system. Statistical tests show that price elasticities are random, but expenditure elasticities are not. The statistical tests allow one to count the number of factors that cause randomness without requiring one to know what they are. There appear to be only two factors that make the price elasticities random. |

| A dynamic econometric model relating wholesale meat prices to retail prices and wholesale meat demand is estimated using monthly data on U.S. prices and quantities of beef, pork, and chicken. The hypothesis that meat retailing costs are separable is rejected; that is, the data support joint costs in meat retailing. The hypothesis that there are fixed proportions between wholesale meat inputs and retail meat outputs is accepted. |

| In early 1996, the peak in the current cycle of cattle inventories coincided with a long list of negative factors--negative returns at the farm and feedlot, record-high feed grain prices, a severe drought in 1995-96, widening farm-retail price spreads, a low farmers' share of the consumers' Choice beef dollar, and reports of high profits for beefpackers. This confluence created an atmosphere in which some producers and members of Congress questioned whether the cattle industry was adversely affected by high packer concentration and market power. In this report, we examine the cattle cycle of the 1990's to determine if there are differences from previous cattle cycles and, if so, how and why they are different. We found that values for many variables at the... |

| Recent bovine spongiform encephalopathy (BSE, a.k.a. mad cow disease) discoveries in Canadian and U.S. beef cattle have garnered significant media attention, which may have changed consumers’ meat-purchasing behavior. Consumer response is hypothesized and tested within a meat demand system in which response is measured using single-period dummy variables, longer-term dummy variables, and media indices that count positive and negative meat-industry articles. Parameters are estimated using retail scanner data, and cross-species price elasticities are calculated. Results suggest that the BSE events negatively impacted ground beef and chuck roasts, while positively impacting center-cut pork chop demand. Dummy variables explained the variation in meat-budget... |

| As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices, and frozen imports became more responsive. Unconditional own-price elasticities also show that, over time, imports of chilled lamb became less responsive to import prices while frozen imports became more responsive to import prices. |

| Estimates of price and scale demand elasticities for lamb and mutton consumed in the United States are derived. The U.S. lamb and mutton consumption comprises primarily of domestic production, and imports from two countries-Australia and New Zealand. The Netherlands Central Bureau of Statistics (CBS) demand system derived by Keller and Van Driel (1985) is employed. The CBS model is preferred as it combines non-linear Engel curves with the simplicity of the Slutsky matrix and allows for the ease of implementing concavity and other restrictions. Empirical results for own-price elasticities of demand indicate that U.S. demand for Australian lamb demand is highly elastic while U.S. demand for New Zealand and domestic lamb was inelastic. The scale demand... |
