Price and expenditure elasticities at retail level for 11 fresh fruits and 10 fresh
were estimated by employing a composite demand system approach and using annual
data. Most fresh fruits and vegetables were found to respond significantly to changes
their own prices but insignificantly to changes in total expenditures. The demand
fresh fruit group appeared to have had a clear upward trend since 1973. However,
significant trends were found in the demands for individual fresh fruits or vegetables.
The study partially incorporated the interdependent demand relationships between
fruits (vegetables) and all other commodities, yet effectively avoided the problem
insufficient degrees of freedom.
