Correct answer(s):
- None of the statements associated with this question are correct
The demand for video recorders has been estimated to linear and given by the demand relation QV = 145 – 3.2PV + 7M – 0.95PF – 39PM, where QV is the quantity of video recorders, Pf denotes the price of video recorder film, PM is the price of attending a movie, PV is the price of video recorders, and M is income. Based on the estimated demand equation we can conclude:
Correct answer(s):
- Video recorders are normal goods and video recorder film is a complement for video recorders

The management of Local Cinema has estimated the monthly demand for tickets to be lnQ = 22,328 – 0.41 lnP + 0.5 lnM – 0.33 lnA + 100 lnPvcr, where Q = quantity of tickets demanded, P = price per ticket, M = income, A = advertising outlay, and Pvcr = price of a VCR tape rental. It is known that P = $5.50, M = $9,000, A = $900, and Pvcr = $3.00. Based on the information given, which of the following statements is false?
Correct answer(s):
- Movies are complements for VCR tapes
The management of Local Cinema has estimated the monthly demand for tickets to be lnQ = 22,328 – 0.41 lnP + 0.5 lnM – 0.33 lnA + 100 lnPvcr, where Q = quantity of tickets demanded, P = price per ticket, M = income, A = advertising outlay, and Pvcr = price of a VCR tape rental. It is known that P = $5.50, M = $9,000, A = $900, and Pvcr = $3.00. Determine the own-price elasticity of demand for movie tickets
Correct answer(s):
- -0.41
