This study explores the growth in demand for fast food. A distinguishing ch
aracteristic of fast food is its convenience; in today's pervasive marketpl
ace, consumers need not travel far to find a fast food outlet. This greater
availability translates into a decrease in the full price of obtaining a m
eal, which. contributes to greater consumption. Market-level data are used
to estimate demand equations in two time periods, incorporating changes in
availability as well as prices, income, and various demographic characteris
tics. Our findings show that greater availability has led to increased cons
umption. Failure to account for these types of marketplace changes could le
ad to incorrect inferences regarding the factors responsible for the indust
ry growth.
