Question

During a recession, median income falls by 15%. if the demand for grapes falls by 12%, grapes are a(n) _____ good with an income elasticity of demand of

Answer 1

Grapes are a(n) "normal good" with an income elasticity of demand of "0.8". A normal good is a good for which an increase in income results in increased demand, while decreased income results in decreased demand. Thus, we know that the first blank is "normal good" by the definition of a normal good becuase median income fell and demand for grapes fell. The X elasticity of demand is given by (%change in Demand)/(%change in X), where x is any economic variable (income in this case). Thus, to find the elasticity, we divide 12% by 15%. 12%/15%=.08.
