g Suppose Marcia's Manioc Farm is a non-price discriminating monopolist producing manioc and is producing its profit-maximizing level of output. Suppose further that at her current level of output, Marcia's average total cost is $1.50, her average variable cost is $1.00, and her marginal cost of producing an additional kilo of manioc is $1.40. Marcia's economic profit is in the short run.
