What is then the use or relevance of the purely competitive model?
Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run competitive equilibrium, with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power.
The following graph shows the demand (D�) and supply curves (S=MC�=MC) in the market for hot dogs.
Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from perfect competition.
Assume that one of the hot dog vendors successfully lobbies the city council to obtain the exclusive right to sell hot dogs within the city limits. This firm buys up all the rest of the hot dog vendors in the city and operates as a monopoly. Assume that this change doesn't affect demand and that the new monopoly's marginal cost curve corresponds exactly to the supply curve on the previous graph. Under this assumption, the following graph shows the demand (D), marginal revenue…
Consider the weekly market for gyros in a popularneighborhood 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 (SMC) 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.

Consider the welfare effects that result from the industry operating as a competitive market versus a monopoly. On the monopoly graph, use the black points (plus symbol) to shade the area that represents the loss of welfare, or deadweight loss, caused by a monopoly. That is, show the area that was formerly part of total surplus and now does not accrue to anybody. Deadweight loss occurs when a market is controlled by a monopoly because the resulting equilibrium is different from the (efficient) competitive outcome.

- How is non-price competition different from price competition?arrow_forwardThe auto industry in the U.S. has long been dominated by the Big Three carmakers: Ford, General Motors, and Chrysler. The auto industry in China, on the other hand, has more than 170 carmakers. Automakers in the U.S. have some monopoly power while the car market in China has the characteristics of a perfectly competitive market. Based on these differences in market characteristics, explain how car makers in the U.S. will “behave” compared to carmakers in China. In particular, address the following considerations: How will carmakers in the U.S. respond to consumers’ desires compared to Chinese carmakers’ response to consumers’ desires, everything else being equal?arrow_forwardThe auto industry in the U.S. has long been dominated by the Big Three carmakers: Ford, General Motors, and Chrysler.
