The following graph shows a firm operating in a monopolistically competitive market. Short term, how many haircuts will the firm perform and at what price? At this point, what will its total revenue, total cost, and total profit be? Given your answers, what would we expect to happen in the long term in this market (i.e. are we at long term equilibrium, or will we see further changes)?
Suppose that a company operates in the monopolistically competitive market for denim jackets. The following graph shows the demand curve,
marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve for the firm.
Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Nex
place a grey point (star symbol) to indicate the minimum average total cost the firm faces and the quantity associated with that cost.
