DEMAND & SUPPLY ESTIMATION Option 1: Note: The following is a regression equation. Standard errors are in parenthesis for the demand of widgets. QD= - 5200 - 42P + 20Px + 5.2I + 0.20A + 0.25M (2.002) (17.5) (6.2) (2.5) (0.09) (0.21) R2= 0.55, N = 26 F= 4.88 Your supervisor has asked you to compute the elasticity for each independent variable. Assume the following values for the independent variables: Q D = Quantity demanded ( Quantity demanded of 3 - pack units) P (in cents) per case = Price of the product = 500 cents PX (in cents) = Price of leading competitor’s product = 600 cents I (in dollars) = Per capita income of the standard metropolitan statistical area (SMSA) where the supermarkets are located = 5500 $ A (in dollars) = Monthly advertising expenditures = $10,000 M = Number of microwave ovens sold in the SMSA in which the supermarkets are located = 5,000

DEMAND & SUPPLY ESTIMATION Managerial Economics & Globalization Assignment 1: Demand and Supply Estimation Your name Your Instructor’s name Course Id: Your Institution’s name Date: Demand and Supply Estimation 1. Compute the elasticity for each independent variable. Note: Write down all of your calculations. Solution: When P= 500, M= 5000, A= 10,000, I = 5,500, C=600, By putting values of P, M, A, I and C in the regression equation we get, QD= - 5200 – 42(500) + 20(600) + 5.2(5500) + 0.20(10000) + 0.25(5000 ) = 17,650 As we know that: Price Elasticity ( Ep ) = (P/Q) ( ∆ Q/ ∆ P) From the regression equation we get, ∆ Q/ ∆ P = - 42. So, Price Elasticity (Ep) = (P/Q) ( - 42) (500/17650) = - 1.19, similarly,
