| Fats and oils play a prominent role in U.S. dietary patterns. Recent concerns over the negative health consequences associated with fats and oils have led many to suspect structural change in demand conditions. Our analysis considers short run (monthly) demand relationships for edible fats and oils. In that monthly quantities of fats and oils are likely to be relatively fixed, an inverse almost ideal demand system specification is used. A smooth transition function is used to model a switching inverse almost ideal demand system that assesses short-run demand conditions for edible fats and oils in the United States. The results suggest that short-run demand conditions for fats and oils experienced a gradual structural shift that began in the late 1980s... |

| The last three years have realized significant structural changes in the U.S. agricultural policy environment. These changes include nearly complete planting flexibility and the elimination of target-price-based income support for agricultural producers. Many have questioned the extent to which such policy changes may influence the variability of agricultural prices. This analysis uses price series dating from 1944 to develop a multivariate framework to evaluate the long-run (inter-season) determinants of endogenous variability for the prices of corn, wheat, and soybeans. An annual measure of price variability is calculated from monthly spot market cash prices for each of the three commodities. The generalized method of moments estimation technique is... |

| Fats and oils play a prominent role in U.S. dietary patterns. Recent concerns over the negative health consequences associated with fats and oils have led many to suspect structural change in demand conditions. We consider short run (monthly) demand relationships for edible fats and oils. In that monthly quantities of fats and oils are likely to be relatively fixed, we utilize an inverse AIDS specification. Our analysis consists of two components. In the first, we utilize a smooth transition function to model a switching inverse almost ideal demand system (IAIDS) that assesses short-run demand conditions for edible fats and oils in the U.S. Our results suggest that short-run demand conditions for fats and oils experienced a rather rapid structural shift in... |

| The oilseed products complex is an important component of the U.S. agricultural sector. In 2000, almost 75 million acres were planted to soybeans, representing over 29 percent of total planted acreage, making soybeans second only to corn in terms of acreage (ERS/USDA, 2000). Soybean acreage has increased steadily since 1990, when only 58 million acres were planted. From a historical perspective, soybeans are rather unique in that they were not eligible for target-price deficiency payments nor were they subject to the explicit acreage restrictions of other program crops. However, the acreage-idling and base-acreage requirements, as well as government stock-holding behavior, of other program crops has indirectly affected soybean acreage decisions in the... |
