Estimating Industry Demand for Fresh Market Broccoli The market for broccoli is comprised of two segments: fresh market broccoli, which have excellent, uniform color and a small core, and processing broccoli, which are larger than fresh market broccoli but still have good flavor, color, and texture. Annual data for the years 1983-2000 in the fresh market segment of the broccoli industry are presented below. Q is total annual fresh market broccoli production (measured in thousands of hundred weight units, which are 100,000 pound units), P is average annual real price per hundred weight of fresh market broccoli (in constant 2011 dollars),1 and W is a weather index based on temperature and rainfall (W varies directly with conduciveness of weather for growing broccoli). To account for the increasing popularity of broccoli during the sample period, the time variable t is added to the demand equation to reflect growing popularity of broccoli. The production data do not account for imports and exports of broccoli. During the period of this sample, however, net exports of broccoli (exports minus imports) were quite small in every year.
