Suppose the pizza market in the S.U. area is competitive. Assume the market is in a long run competitive equilibrium.

  • Graphically represent the pizza market. Be sure to show two pictures, one representing the pizza market and the other representing the individual pizzeria.

  • Suppose there is a large increase in student enrollment at S.U. How will this affect the market for pizza and the profits of the individual pizzeria? Explain and demonstrate on your graphs from part a. If the individual pizzeria is making a profit, be sure to clearly label the size of the profit on your graphs.

  • Based on your answer in part b, what adjustments will occur in this market overtime? Explain and demonstrate on your graphs from part a.

Answer #1

Large increase innstudents enrollment leads to rise in demand for pizza.

Demand curve shifts rightwards from D1 to D2. Equilibrium Price level rises from P1 to P2 in the market.

Equilibrium in the firms market moves from A to B.

a. Positive economic profit= Area of rectangle below P2 above ATC bounded by Q2.

b. For firms Price is greater than Average Total cost now. So firms are earning positive economic profit now. New firms will enter the market, this will drive down the Profit earned by individual firm.

So in the long run, firms will again start to earn normal profit.

1. Suppose a competitive firm previously set its price at $15 per unit to maximize its profit, which had been positive. Then the market price falls to $12 and the firm adjusts in order to maximize its profits at the decreased price. After these adjustments what can we conclude about the firm’s quantity of output, average total cost, and marginal revenue in terms of being higher, lower, or the same as before? 2. At current output a profit maximizing competitive...

Suppose Michael’s friend James makes the following statement, “Economic theory states that in a purely competitive market, profits should be zero in the long-run, but Michael’s friend, Johnson, who owns a pizza restaurant indicates that if he really made zero profit, he wouldn’t be able to support his family and would shut down. So if profits tend to zero, small businesses like Johnson’s restaurant will have to close down. Assume the pizza market is purely competitive, using your knowledge, evaluate...

Assume that a monopsony firm and a perfectly competitive labor market. Contrast the two with respect to (a) wage rate, (b) employment level, and (c) profit maximization condition. Since both monopolists and competitive firms follow the MFC = MRC rule in maximizing profits, how do you account for the different results? Why might the labor supply of a perfectly competitive firm and those of a monopolist be different? What are the implications of such a difference? Show your discussions graphically.
