In India, Cisco’s market share of the Ethernet switch and router market is approximately 67 percent. Juniper and HP each have market shares of about 6.5 percent, and several other firms have somewhat smaller market shares. Draw a diagram showing the equilibrium in this dominant firm market. Identify the equilibrium price and the equilibrium quantity produced by the dominant firm and the competitive fringe firms. Illustrate what happens to the equilibrium price and the equilibrium quantity produced by the dominant firm and the competitive fringe firms if additional fringe firms enter the market

Consider the weekly market for gyros in a popular neighborhood close to campus. Suppose this market is operating in long-run competitive equilibrium with many gyro vendors in the neighborhood, each offering basically the same gyros. Due to the structure of the market, the vendors act as price takers and each individual vendor has no market power. The following graph displays the supply (S = MC) and demand (D) curves in the weekly market for gyros. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition. PRICE (Dollars per gyro) 5.0 4.5 4.0 3.5 3.0 2.0 1.5 1.0 0.5 0 0 10 20 30 Competitive Market 40 60 QUANTITY (Gyros) 50 70 80 S=MC D 90 100 PC Outcome (?) Now assume that one of the gyro vendors successfully petitions the neighborhood development board to obtain exclusive rights to sell gyros in the neighborhood. This firm buys up all the rest of the gyro food trucks in the area and begins to operate as a monopoly.…
