•Implicit and explicit Costs •A firm’s cost of production includes explicit costs and implicit costs Economic profit-total revenue minus total cost, including both explicit and implicit costs Accounting profit-firm’s total revenue minus only firm’s explicit costs Production Function-shows the relationship between quantity of inputs used to make a good and quanity of output of that good, short fun As Input increase, output increases…diminishes at higher scale, short fun phenomenon “too many cooks spoil the broth” Marginal profuct-any input in the production process is the increase in output that arises from an additional unit of that input MP labor = DELTA output/ DELTA input (labor) The slope of the production f(n) measures the marginal produce of an input, such as a worker. When the marginal product declines, the production f(n) becomes flatter. The total-cost curve shows the relationship between the quantity a firm can produce and its costs graphically. Costs of production may be divided into fixed costs and variable costs

In the short run, some costs are fixed. In the long run all fixed costs become variable....
