Document Summary
Explicit cost: a cost that requires an outlay of money. Implicit cost: does not require an outlay of money. It is measured by the value, in dollar terms, of benefits that are forgone. Total opportunity cost: total explicit cost + total implicit cost. Accounting profit: equal to revenue minus explicit cost. Economic profit: equal to revenue minus the opportunity cost of resources used. Economic profit is usually less than the accounting profit because of the added implicit cost. When the word profit is used it refers to economic profit in economics. Capital: the total value of assets owned by an individual or firm physical assets plus financial assets. Economists like to distinguish between financial assets, such as cash, stocks, and bonds, and physical assets, such as buildings, equipment, tools, and inventory. Implicit cost of capital: the opportunity cost of the use of one"s own capital the income earned if the capital had been employed in its next best alternative use.
