Demand of U.S. Imports of Fresh Citrus Products: An Incomplete LINQUAD Demand Approach

Recent developments in the markets of oranges, clementines, and tangerines call for more scrutiny on the import behavior of citrus. Imports of these products are highly variable during the period from 1989 to 2003. Imports are characterized by marked seasonality, variable price, and unobservable quantities and prices. Incomplete LINQUAD demand approach is estimated using semi-annual import data. Symmetry and negative semi-definiteness of the Slutsky matrix are not rejected. Own and cross price elasticities are small in general. Income elasticity estimates are diminishing.
