Chapter 9 Lecture Notes 1 Economics 352: Intermediate Microeconomics Notes and Sample Questions Chapter 9: Profit Maximization Profit Maximization The basic assumption here is that firms are Profit maximizing. Profit is defined as: Profit = Revenue Costs (q) = R(q) C(q) )q(Cq)q(p(q) = To maximize profits, take the derivative of the Profit function with respect to q and set this equal to zero. This will give the quantity (q) that maximizes profits, assuming of course that the firm has already taken steps to minimize costs. dqdCdqdR0dqdCdqdRdqd== = or, put slightly differently, the Profit maximizing condition is for marginal revenue to equal marginal cost: MR = MC Or, put slightly differently, the additional revenue gained by making and selling one additional unit should be equal to the extra cost incurred to mak
Chapter 9: Profit Maximization Profit Maximization The basic assumption here is that firms are profit maximizing. Profit is defined as: Profit = Revenue – Costs Π(q) = R(q) – C(q) To maximize profits, take the derivative of the profit function with respect to q and set this equal to zero.
