A)Qd=25,000-80p+0.25M+72Pr
Qd=25,000-80*100+0.25*35,000+72*60=30,070
B) price Elasticity={∆Qd/∆p)*p/Q=(-80)*(100/30,070)=-0.266
Demand is inelastic. So Decrease in price will increase in Quantity demanded lower percentage than Decrease in price . So as a result total revenue will decrease.
C) Income Elasticity=(∆Qd/∆M)*M/Qd=0.25*35,000/30,070=0.29
Positive income tells that good is normal
a 3.5% decrease in income will decrease demand=3.5*0.29=1.015%
D) cross Elasticity={∆Qd/∆pr)*pr/Qd=72*60/30,070=0.143
Positive cross elasticity tells that goods are substitues
6% Increase in price of pr will increase demand=6*0.143=0.858%

A3 Own Price Elasticity Question 1: The demand for Wanderlust Travel Services (good X) is estimated to be Qx = 22000-2.5Px + 4PY-1 M 1 .5Ax. Where Qx is the quantity of good X, Px is the price of good X, Py is the price of good Y, M is consumer income, and Ax is the amount of advertising spent on X. Suppose the price of good X is $450, the price of good Y is $40, the company uses...
Optimal Consumption of good x and good y: Maximization Rule - Maximization of Utility given a Budget Constraint = Marginal Utility of good x/Price of good x = Marginal Utility of good y/Price of y Calculate Consumption Bundle using the following information: Price of Good x = $5, Price of Good y = $16 and Income = $100 / 0 Quantity Consumed Total Utility Quantity Consumed Total Utility Calculate: a.) Price Elasticity of Demand =% Change in Quantity Demanded/%Change in...
Suppose that the demand and supply functions for good X are Qd = 56 – 2PX + 0.01M +7PR Qs = -600 + 10PX Where PX is the sales price of good X, M is average consumer income, PR is the price of a related good. Is good X a normal or inferior good? Are good X and R complements of substitutes? Explain? Suppose M = $50,000 and PR = $20 What is the direct demand function for good X?...
The estimated demand for a good Is Q 3,600- 12P+ 0.6M- 2.5PR where Q Is the quantity demanded of the good, Pis the price of the good, Mis Income, and P Is the price of related good R. This good and good Rare O substitutes because the coefficlent on P Is negative. O complements because the coefficlent on MIs positive. O substitutes because the coefficlent on M Is positive. O complements because the coefficlent on PR Is negative.
The demand function for good X is as follows: X= 25 + 5Py + 5B -2Px A. What is the slope of this demand curve? B. If Px=10, Py=3, and B= 10 derive the: a. Own demand elasticity at these values b. Cross elasticity at these values c. Income elasticity at these values. C. Is good X elastic or inelastic at these values for income, price of good Y and price of good X? Is good Y a substitute or complementary good? And, is good X an...
The general demand and supply functions for good A are QD-2, 800-6P 0.5M-10PB Qs 40 4P - 8P1+6F where QD is the quantity demanded of good A, Qs is the quantity supplied of good A, P is the price of good A, M is the averaged income level of consumers, Pb is the price of a related good B, Pr is the price of an input, and F is the number of firms producing good A (a) Is good A...
Suppose the following is an estimated log-linear demand function: ln Q = 8.99 – 3.78 ln P – 1.77 ln M – 2.03 ln PR All parameter estimates are significant. 1) Is this good a normal or an inferior good? 2) Is this good a complement of or substitute for the related good? 3) What is the price elasticity of demand for this good? 4) What is the income elasticity of demand for this good?
Consider that the general demand function for a product X is estimated to be Qd = 500 – 5P + 0.5M + 10PY - 2PZ Where Qd is quantity demanded of good X, P is price of good X, M is consumer income (in thousands), PY is price of good Y, and PZ is price of good Z. a. Based on the estimated demand function, what is the relationship between good X and good Y; between good X...
