If a firm shuts down, it
incurs an economic loss equal to its total fixed cost.
explicit cost
is a cost paid in money

is a firm that cannot influence the price of the good or service that it produces.
The long run
is a time frame in which the quantities of all resources can be changed.
The short run
is a time frame in which the quantities of some resources are fixed. In the short run, a firm can usually change the quantity of labor it uses but not the quantity of capital (fixed plant size).
economic depreciation
is an opportunity cost of a firm using capital that it owns — measured as the change in the market value of capital over a given period.
In perfect competition, marginal revenue
is equal to the market price.
marginal revenue
is the change in total revenue that results from a one-unit increase in the quantity sold (MR = Price!)
Total Fixed Cost (TFC)
is the cost of a firm's fixed factors of production used by a firm—the cost of land, capital, and entrepreneurship. We describe the relationship between output and cost using three cost concepts: -Total fixed cost doesn't change as output changes.
Total variable cost (TVC)
is the cost of the variable factor (labor) of production. To change its output in the short run, a firm must change the quantity of labor it employs. -Total variable cost changes as output changes
The long run is a time period that is
long enough to change the size of the firm's plant and all other inputs.
If the wheat industry is perfectly competitive with a market price of $4 per bushel and Farmer Brown charged $5 per bushel, how many bushels would Farmer Brown sell?
none
the return to entrepreneurship, which is what the firms owner could earn running another business, is known as
normal profit
Jennifer's Bakery Shop produces baked goods in a perfectly competitive market. If Jennifer decides to produce her 100th batch of cookies, the marginal cost is $120. She can sell this batch of cookies at a market price of $110. To maximize her profit, Jennifer should
not produce this additional batch.
As a typical firm increases its output, its marginal cost
decreases at first and then increases.
A perfectly competitive firm is producing 50 units of output and selling at the market price of $23. The firm's average total cost is $20. What is the firm's economic profit?
$150

Juan's Software Service Company is in a perfectly competitive market. Juan's total fixed cost is $25,000, his average variable cost at 1,000 service calls is $45, and marginal revenue is $75. Juan's makes 1,000 service calls a month. What is his economic profit?
$5,000
Total variable cost
Includes the cost of labor
Perfect competition means
Many firms sell an identical product to many buyers. • There are no restrictions on entry into (or exit from) the market. • Established firms have no advantage over new firms. • Sellers and buyers are well informed about prices.
The Firm's (Economic) Goal?
To maximize profit (= revenue - cost)
TFC/TVC/TC on graph?
Total fixed cost (TFC) is constant - a horizontal line. Total variable cost (TVC) increases as output increases. Total cost (TC) also increases as output increases.
total fixed cost is the cost of
a firm's fixed factors of production
A subsidy is
a payment by the government to a producer to cover part of the cost of production.
implicit cost is
an "opportunity cost" incurred by a firm when it uses a factor of production which does not involve direct money payment. The two main implicit costs are • economic depreciation • cost of using the firm owner's resources
increasing marginal returns to labor
are the results of specialization and division of labor in the production process
what always decreases when output increases?
average fixed cost
average total cost equals
average fixed cost + average variable cost
Average total cost equals
average fixed cost plus average variable cost.
An effective price support ________ producers and ________ a deadweight loss.
benefits; creates
Under perfect competition,
buyers and sellers have a lot of information about prices.
a price-taking firm
cannot influence the price of the product it sells
A perfectly competitive firm is earning an economic profit when total fixed costs increase. Assuming the firm does not shut down, in the short run the firm will
continue producing the same quantity as before but will earn less economic profit.
Jay set up his hotdog stand near the business district. His total variable cost includes the
cost of hot dogs and condiments
Jerry's Jellybean Factory produces 2,000 pounds of jellybeans per month and sells them in a perfectly competitive market. The marginal cost is $3 per pound, the average variable cost is $2 per pound, and the beans sell for $4 per pound. Jerry

A firm pays $50,000 for a machine that is used in production for one year, after which it is sold for $40,000 to another firm. The $10,000 difference is
economic depreciation, an implicit cost of production.
When a firm's long-run average total cost decreases as its output increases, the firm is experiencing
economies of scale
when a firm's long-run average total cost decreases as its output increases, the firm is experiencing

economies of scale are present
when the long-run average cost curve is downward sloping
economies of scale are present
economic profit
equals total revenue
Economies of scale
exist if when a firm increases its plant size and labor employed by and average total cost decreases. The main source of economies of scale is greater specialization of both labor and capital.
Diseconomies of scale
exist if when a firm increases its plant size and labor employed by and average total cost increases. Diseconomies of scale arise from the difficulty of coordinating and controlling a large enterprise.
Henry, a perfectly competitive lime grower in southern california, notices that the market price of limes is greater than his marginal cost. What should henry do?

The main source of economies of scale is
greater specialization of both labor and capital.
A perfectly competitive firm definitely earns an economic profit in the short run if price is
greater than average total cost.
If total fixed cost increases, which of the following will NOT change?

the firm's supply curve is its
marginal cost curve above the average variable cost curve.
If a business owner decided to expand her business but rather than borrowing money from a bank used her own funds, then
she would forego the opportunity to earn interest on the money.
Suppose that marginal revenue for a perfectly competitive firm is $20 . When the firm produces 10 units, its marginal cost is $20, its average total cost is $22, and its average variable cost is $17. Then to maximize its profit in the short run, the firm
should stay open and incur an economic loss of $20.
