A brand has the exclusive right to sell Star Wars t-shirts in Germany. The demand for these t-shirts is Q = 70 – P.
• a. If brand can produce at constant average costs of AC = 6, what output level will brand choose in order to maximize profits? What is the price at this output level? What are the brand’s profits? Show your result in the related graph.
• b. Assume instead that brand has a cost structure where total costs are described by TC = 0.25Q2 – 5Q + 300 With the monopolist facing the same market demand and marginal revenue, what price quantity combination will be chosen now to maximize profits? What will profits be? Show your result in the related graph.
• c. Assume now that a third cost structure explains the brand’s position, with total costs given by TC = 13Q3 – 5Q2 + 5Q + 250 Again, calculate brand’s price-quantity combination that maximizes profits. What will profit be? Show your result in the related graph.

Solutions

Expert Solution

Given demand function: Q = 70 – P. The inverse demand function would be P = 70 - Q. Since this brand has exclusive right to sell t-shirts, so it is a monopoly. The equilibrium condition for a monopoly is MC = MR.

The demand curve for T-shirts in the US is given by Q = 100 – 2*P. Suppose that there are no T-shirts produced in the US, but they can be imported either from Mexico or from the rest of the world. The price of T-shirts in Mexico is $20, and the price from the lowest-cost supplier in the rest of the world is $15. The US charges a tariff of $10 per unit imported. a) Consider the case where there...
