What are costs: total revenue, total cost and profit. All businesses are just trying to maximize profit. Total revenue (for a firm): the amount a firm receives for the sale of its output. Total cost: the market value of the inputs a firm uses in production. Profit: total revenue total cost: costs as opportunity costs. Explicit costs: input costs that require an outlay of money by the firm. Implicit costs: input costs that do not require an outlay of money by the firm. Opportunity costs: the cost of capital as an opportunity cost. E. g. interest received from money otherwise invested: economic profit versus accounting profit. Economic profit: total revenue minus total cost including both explicit and implicit costs. Accounting profit: total revenue minus total explicit cost. If economic profit is negative, firms will close down or change area of business. People can change their input costs over time: the production function.
