This thesis estimates a demand system for natural fruit juices and flavored citrus drinks. Consumption and price data from the Florida Department of Citrus is used to estimate a Linear Approximate Almost Ideal Demand System for natural fruit and fruit juice drink elasticities. The monthly data covers the period from October 2004 to June 2014. Elasticities show orange juice does not have a substitute among the other beverages. 100% orange juice and grapefruit juice are compliments, although other studies have found them to be substitutes.
