In a graph for a firm in pure competition with the quantity of output measured on the horizontal axis, the total revenue curve is
profit maximizing/ loss minimizing rule
MR = MC rule is known as the
decrease in marginal cost for firms in the industry and an increase in the industry supply curve
The resource cost falls in a purely competitive industry. This change will result in a(n)
all market structures
Unit price and average revenue are the same or equal in
pure
_____ competition is considered to be rare in the real world
marginal; production
_____ revenue is the additional revenue that an additional unit of _____ would add to total revenue
pure
a _____ competitive firm's average-revenue schedule is also known as its demand schedule
large number of sellers
a basic feature of the purely competitive market is the presence of _____
variable; greater than
a firm should stop producing if its average _____ cost is _____ price
purely
a firm will not increase its product price in a _____ competitive market
marginal cost is equal to marginal revenue
a firm within a purely competitive market can maximize its profit in the short run by producing up to the point where
1. it will experience the highest possible profits at this point and 2. it will experience the lowest possible losses at this point
a firm within pure competition will produce up to the point where marginal revenue equals marginal cost because
false; MP must exceed the minimum average variable cost
a purely competitive firm in the short run will maximize profit by producing up to the point where marginal revenue is equal to marginal cost if the market price is less than minimum average variable cost
a, c
a purely competitive firm's demand schedule equals its a. marginal-revenue schedule b. total-revenue schedule c. average-revenue schedule
a
all of the following describe purely competitive firms, except a. they engage in non-price competition b. they produce standardized products c. they make no attempt to differentiate their products d. they produce homogeneous products e. they produce identical products
$69.50 in a perfectly competitive market, price is equal to marginal revenue Profit/Loss = (price - ATC)Quantity; price = MR
at a profit-maximizing level of output of 25 units, a perfectly competitive firm's marginal revenue is $4, average variable cost is $0.30, average total cost is $1.22 and marginal cost is $3.75. This firm's economic profit equals
by comparing marginal revenue to marginal costs; by comparing total revenue to total costs
by which two ways can a purely competitive firm determine the level of output at which it will realize maximum profit or minimum losses
four
economists group industries into _____ distinct market structures
do not differentiate their products
firms that operate in a purely competitive industry
takers
firms within pure competition are considered to be price _____
a normal; a zero
from an economic standpoint, the break-even point is the level of output at which a firm makes _____ profit
less; variable
if price is _____ than a firm's minimum average _____ cost, the firm will not operate
equal to; equal to
in a perfectly competitive market, price is _____ marginal revenue, therefore, price is _____ marginal cost at the profit-maximizing output
substitute other firm's products such as B, C, or D
in a purely competitive industry, an increase in the price of product A supplied by one firm will cause consumers of product A to:
revenue; marginal cost OR cost; price OR revenue; price
in a purely competitive industry, at profit-maximization or loss-maximization, marginal _____ is equal to _____
revenue; marginal
in a purely competitive market, price per unit to the purchaser is synonymous with _____ per unit or _____ revenue to a seller
price
in pure competition, _____ and marginal revenue are equal
marginal revenue minus average total cost multiplied by quantity; price minus average total cost multiplied by quantity
in pure competition, economic profit is calculated as _____ or _____
price; marginal
in pure competition, to calculate economic profit, we first calculate the difference between product _____ or _____ (average) revenue and average total cost and then multiply it by output
enter and exit
in purely competitive industries, firms can freely
product price; the total supply of a product; the firm's demand
in purely competitive markets, an individual firm does not exert control over _____
low; revenue; cost
in the initial stages of production, where output is relatively _____, marginal _____ will usually, but not always, exceed marginal _____
output
in the short run, a purely competitive firm can maximize its economic profit (or minimize its loss) by adjusting its _____
change; one
marginal revenue is the _____ in total revenue that results from selling _____ more unit (extra unit) of output
price; marginal revenue; marginal cost
profit in a purely competitive market is maximized when _____ equals _____ equals _____
pure monopoly; oligopoly; monopolistic competition
the market structures designed as "imperfect competition" are
in the short-run, the firm will maximize profit or minimize loss by producing the output at which marginal revenue equals marginal cost
the profit maximizing rule of MR=MC states that
profit; losses
there are two ways to determine the level of output at which a firm will realize maximum economic _____ or minimum economic _____
not produce that additional unit of output
when the marginal cost of an additional unit of output exceeds the marginal revenue, the firm should
equal; variable; total; fixed
when the price is _____ to a firm's lowest average _____ cost, the firm will be able to cover its _____ variable cost and its loss will equal its total _____ cost
all
which of the following are true about the profit-maximizing rule of MR=MC a. the rule can be re-stated as P=MC when applied to a purely competitive firm because product price and MR are equal b. the rule is an accurate guide to profit maximization for all firms regardless of their market structure c. the rule applies only if producing is preferable to shutting down d. when MR is equal to MC at a fractional level of output, the last complete unit of output should be produced where MR>MC
a relatively large number of sellers producing differentiated products and in which entry or exit from the industry is quite easy
which of the following best describes a monopolistic competition
one firm selling a single unique product, where entry of additional firms is blocked and product differentiation is not an issue
which of the following best describes a pure monopoly
an industry involving a very large number of firms producing identical products and in which new firms can enter or exit the industry very easily
which of the following best describes pure competition
one of a large number of firms producing an identical product as every firm in its industry and only providing a fraction of total market supply
which of the following best describes the situation of a price-taking firm
because the firm would gain more in revenue from selling that unit than it would add to its costs by producing it
which of the following best explains why the firm should produce any unit of output whose marginal revenue exceeds its marginal costs
