Suppose that the market basket for the university student price index (USPI) consists of 5 textbooks and 100 gallons of gasoline. In 2010, the base year for this index, textbooks cost $50 each and gas cost $1 per gallon. In 2011, textbooks cost $80 each and gasoline cost $3 per gallon. The USPI for 2011 is:

Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact thatmr=mc at the optimal quantity for each firm. furthermore, a monopolistically competitive firm's average total cost in long-run equilibrium isless than the minimum average total cost. true or false: this indicates that there is a markup on marginal cost in the market for engines. true false monopolistic competition may also be socially inefficient because there are too many or too few firms in the market. the presence of the externality implies that there is too little entry of new firms in the market.
