Suppose there are two firms in a market, each with marginal costs equal to 0. Due to regulations, the firms must both charge a price of $0. Let A1 and A2 be the advertising expenditure of each firm, and let the demand for the ith firm be qi=6-3(Aj/Ai) a) Assume firms choose their advertising expenditures simultaneously, and calculate the firm's advertising expenditures in equilibrium. b) Now, assume the firms can commit to advertising at the same level (so that A1=A2=A). Does your answer to (a) imply that there is too much or too little advertising (from the perspective of firm profits)?

Suppose you are the economic adviser ofa company producing three brands of mobile pnones;Nokia 10, Samsung X and iPhone 7. Suppose further that, your company currently sells 120units of iPhone Z at e800 per unit, 150 units of Samsung X at e800 per unit and 200 units ofNokia 10 at e100 per unit, but in a bid to maximize profit, the company's managing directorproposes an increase in price of Samsung X from e800 to e1000 per unit for which quantitydemanded is anticipated to fall from 150 to 100 units; iPhone Z from e800 to e 1200 per unitfor which quantity demanded is anticipated to fall from 120 to 100 units; and Nokia 10 from100 to 200 per unit for which quantity demanded is expected to fall from 200 to 100 unitsUsing the mid-polint formula. compute the price elasticity of demand for each brand.From your answer in i, what is the type and economic interpretatiom of each brand'sii.value of elasticity.

Aidan and Celina are the only sellers of jack russell terrier (JRT) inAntigua. Celina chooses her profit maximizing number of JRTs to sell, q1, basedon the number of JRTs that she expects Aidan to sell. Aidan knows how Celinawill react and chooses the number of JRTs that she herself will sell, q2, aftertaking this information into account. The inverse demand function for JRTs isP(q1 + q2) = 2, 000 − 2(q1 + q2). It costs $400 to raise a JRT to sell.(a)  Explain in detail what type of competitors are Aidan and Celina.(b)  If Celina expects Aidan to sell q2 JRTs, what will her ownmarginal revenue be if she herself sells q1 JRTs?(c) What is Celina’s reaction function, R(q2)?(d) Now if Aidan sells q2 JRTs, what is the total number of JRTsthat will be sold?(e) What will be the market price as a function of q2 only?(f) What is Aidan’s marginal revenue as a function of q2 only?(g)  How many JRTs will Aidan sell?(h)  How many JRTs will Celina sell?(i)  What will be the industry price?

As the new general manager of the Grand Palladium Jamaica luxury all-inclusive resort, youare assessing your pricing policies. Currently, the price of a weekend stay is $2,000 perguest. You estimate the marginal cost of serving a guest at $1,600, and while yourpredecessor unfortunately did not leave you data from the pricing experiments and testmarketing she performed, you do know that such experiments were done, and that yourpredecessor was competent.a. What is your best estimate of the elasticity of demand for a weekend stay at the GrandPalladium?b. Your learned that at the current price, the resort is only 80% full on the weekends.Remembering the sense of belonging that you experienced in a crowded subway duringthe rush hour, you contemplate lowering the price so the resort is completely full. What isyour back-of-the-envelope calculation for how much you need to lower the price?c. After some thought you cooled to the idea of full occupancy. Instead, you focused yourenergy and…

itle A reliable 15-year-old babysitter can be a price maker within her own neighborhood. Suppose that th Description A reliable 15-year-old babysitter can be a price maker within her own neighborhood. Suppose that this babysitter wishes to implement a Multipart Pricing Plan. Customers who use her services less than L hours per month will pay a high price of PH dollars per hour. Customers who use her services more than L hours per month will still pay PH dollars for the first L hours, but for any additional hours they can then pay the lower price PL dollars per hour which she will generously set equal to her marginal cost. Assume that market demand is QD = 60 – 10P and her total costs are C = 3Q; so PL = $3 per hour. If she set her high price at $4 per hour, would her customers accept a limit of L = 24 hours per month in order to use the remainder of her services at a price of $3 an hour? Provide a labelled diagram and briefly explain. Suppose that this talented babysitter was…

Aidan and Celina are the only sellers of Jack Russell Terrier (JRT) inAntigua. Celina chooses her profit-maximizing number of JRTs to sell, q1, basedon the number of JRTs that she expects Aidan to sell. Aidan knows how Celinawill react and chooses the number of JRTs that she herself will sell, q2, aftertaking this information into account. The inverse demand function for JRTs isP(q1 + q2) = 2, 000 − 2(q1 + q2). It costs $400 to raise a JRT to sell. Explain in detail what type of competitors are Aidan and Celina?

In 2006, the five leading suppliers of digital cameras in the United States were Canon,Sony, Kodak, Olympus, and Samsung. The combined market share of these five firmswas 60.9 percent. The leading firm was Canon, with a market share of 18.7 percent. Theown price elasticity for Canon’s cameras was –4.0 and the market elasticity of demandwas –1.6. Suppose that in 2006, the average retail price of a Canon digital camera was$240 and that Canon’s marginal cost was $180 per camera.     Suppose you were the CEO of Kodak, what would you do to avoid its business failure?
