If the marginal propensity to consume in a municipality is 0.8, what is the value of the simple multiplier? if a new stadium that adds $30 million in new consumption expenditures is built, what is the impact on the economy based on this multiplier? suppose the marginal propensity to import is 0.3, what happens to the multiplier and to the impact on the economy?

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.
