Extract

The study reported was motivated by a USDA study to develop complete quarterly models of supply and demand for a selected set of fresh salad vegetables. The acreage planted component enters recursively into both the acreage harvested and yield relations used in many of these models. Consequently, predictions of acreage planted are instrumental in predicting total supply and resulting market equilibrium solutions.

In modeling acreage planted over relevant seasons within four regions, various sources of information can be brought to bear. Obviously, data series on past plantings, costs, and prices provide the foundation of statistical estimation of an acreage response model. However, additional information from previous studies, economic theory, and subjective judgment on the part of the researcher also can be incorporated into the model through the use of the mixed estimation technique developed by Theil and Goldberger [8].
