Is there a deadweight loss if a firm produces the quantity of output at which price equals marginal cost? The quantity of the good will be less and the price will be higher (this is what makes the good a commodity). Based on what we've done To contrast the efficiency of the perfectly competitive outcome with the inefficiency of the monopoly outcome, imagine a perfectly competitive industry whose solution is depicted in Figure 10.7 Perfect Competition, Monopoly, and Efficiency. A monopoly can increase output to Q1 and benefit from lower long-run average costs (AC1). We know that monopolists maximize profits by producing at the. When we are showing a loss, the ATC will be located above the price on the monopoly graph. Because demand is decreasing, a consumer's willingness to buy at a higher Q is lower, meaning the additional revenue you'll receive from each unit decreases. A supply curve says what is supplied at a given price, for example, a seller might say, "when the price increases, I will be willing to sell 10 more". to maximize revenue.
