Question

Suppose a research report has estimated the demand for a firm's product as ln QXd = 7 − 1.5 ln PX + 2 ln PY − 0.5 ln M + ln A where:

Px = $15
Py = $6
M = $40,000, and
A = $350

a. Determine the own price elasticity of demand, and state whether demand is elastic, inelastic, or unitary elastic.

Own price elasticity: -1.5

Demand is: elastic

b. Determine the cross-price elasticity of demand between good X and good Y, and state whether these two goods are substitutes or complements.

Cross-price elasticity: 2

These two goods are: Substitutes.

c. Determine the income elasticity of demand, and state whether good Xis a normal or inferior good.

Income elasticity: 

Good X is:

d. Determine the own advertising elasticity of demand.
