Aside from advertising, how can monopolistically competitive films increase demand for their products?
Andreas Day Spa began to offer a relaxing aromatherapy treatment. The film asks you how much to charge to maximize profits. The first two columns in Table 10.5 provide the price and quantity for the demand curve for treatments. The third column shows its total costs. For each level of output, calculate total revenue, marginal revenue, average cost, and marginal cost. What is the profit-maximizing level of output for the treatments and how much will the firm earn in profits?

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?

Larry, Curly, and Moe run the only saloon in town.Larry wants to sell as many drinks as possiblewithout losing money. Curly wants the saloon tobring in as much revenue as possible. Moe wantsto make the largest possible profits. Using a singlediagram of the saloon’s demand curve and its costcurves, show the price and quantity combinationsfavored by each of the three partners. Explain. (Hint:Only one of these partners will want to set marginalrevenue equal to marginal cost.)

Suppose that the restaurant industry in Honolulu is monopolistically competitive and is currently in Stage 2 equilibrium (firms currently make zero profit). The graph below shows the cost curves for a typical restaurant in this industry. (a) Draw a demand curve and an MR that is consistent with this market being in Stage 2 equilibrium. (b) Show the equilibrium price Now suppose an highly-infectious new virus comes to the island, causing demand for restanrant meals to shift in. (c) What would you expect this change in restaurant demand when the number of firms is fixed? Explain. (d) What would you expect the change in demand to do to the number of meals sold, prices and profits of firms in the long run if firms can enter and exit? What happens to the mumber of restaurants?
