proportional to population. The estimated regional populations including Canada are shown in Table E.2. Based upon those months in which Florida is an important supplier, fresh produce shipments from Florida and Mexico were tabulated and are presented in Tables E.3a-3f. Based upon analysis of shipments data, it was determined that Texas should be included in the pepper market for November and December and California competes with Florida in strawberry market in every month in the December through March period. No region could be identified as a viable alternative to Florida for watermelons in May. The monthly shipments by crop were allocated to the four demand regions by population. These figures are shown in Table E.4. Monthly prices by crop and market were computed by averaging the 1988-89 through 1990-91 monthly average prices. These prices are shown in Table E.5. Using the estimated flexibilities, monthly shipments, and monthly prices, a price dependent linear demand function was developed. Using the notation from the mathematical presentation, the inverse demand for commodity k in month m and demand region j is Pj = aj bjb Qj The formula for a price flexibility is Sap. Qef where the price P flexibility for commodity k in month m and demand region j. where q*. is the price flexibility for commodity k in month m and demand region j.
