Given that profit is defined as the difference in total revenue and total cost, a firm achieves its maximum profit by operating at the point where the difference between the two is at its greatest. The goal of maximizing profit is also what leads firms to enter markets where economic profit exists, with the main focus being to maximize ...
The profit model may represent actual data (c), planned data (p)or standard data (s) which is the actual sales quantities at the planned costs. The actual data model will be (using equation 8): π = p c *q c - [F c + (mμ c + lλ c + n c)q c] The planned data model will be (using equation 8): π = p p *q p - [F p + (mμ p + lλ p + n p)q p]
Profit maximization using the total revenue and total cost curves of a perfect competitor. To obtain the profit maximizing output quantity, we start by recognizing that profit is equal to total revenue minus total cost (). Given a table of costs and revenues at each quantity, we can either compute equations or plot the data directly on a graph.
Suppose the production function is = / /. The unmaximized profit function is (,,,,) =. From this can be derived the profit-maximizing choices of inputs and the maximized profit function, a function just of the input and output prices, which is
Mathematically, the markup rule can be derived for a firm with price-setting power by maximizing the following expression for profit: = () where Q = quantity sold, P(Q) = inverse demand function, and thereby the price at which Q can be sold given the existing demand C(Q) = total cost of producing Q.
Important to note, in this case, the market demand is continuous; however, the firm's demand is discontinuous, as seen in the above function statement. This means the firm's profit function is also discontinuous. [5] Therefore, firm aims to maximise its profit, as stated below, taking as given: [10]
Cost–volume–profit (CVP), in managerial economics, is a form of cost accounting. It is a simplified model, useful for elementary instruction and for short-run decisions. It is a simplified model, useful for elementary instruction and for short-run decisions.
These functions describe each firm's optimal (profit-maximizing) quantity of output given the price firms face in the market, , the marginal cost, , and output quantity of rival firms. The functions can be thought of as describing a firm's "Best Response" to the other firm's level of output.
