The following is the estimated regression equation for Assignment 1 which quantifies the demand for Widgets (purchased by the case - 10 microwavable entres per case). Standard errors are in parentheses.

QD = 20,000 - 10P + 1500A + 5PX + 10 I
(5,234) (2.29) (525) (1.75) (1.5)
R2 = 0.85 n = 120 F = 35.25

Your supervisor has asked you to compute the elasticities for each independent variable, ( P, A, PX, and I), in the equation. Assume the following values for the independent variables:

Q D = Quantity demanded
P (in cents) per case = Price of the product = 8,000
PX (in cents) = Price of leading competitor's product = 9,000
I (in dollars) = Per capita income of the standard metropolitan statistical area (SMSA) where the supermarkets are located = 5,000
A (in dollars) = Monthly advertising expenditures = 64
