2. economic profit
3. normal profit
question
accounting profit formula
answer
total sales (-) explicit costs
question
accounting profit
answer
useful for accountants who are hired to determine the taxable income of the firm ; does not include implicit costs
question
economic profit formula
answer
total revenue (-) explicit and implicit costs
question
economic profit
answer
type of profit a firm wants; includes implicit costs to compensate for time an energy
question
if economic profit>1
answer
the sales receipts of the firms cover more than the opportunity cost of all the resources used; convinces firms to join an industry
question
if economic profit=0
answer
normal profit
question
normal profit
answer
firms stay in business; all the resources are receiving the same amount they would receive if used in their best alternative uses
question
if economic profit<1
answer
economic loss; firms may edit the industry or decrease production
question
short run
answer
amounts of at least one of the factors of production the firm uses can't be changed
question
variable factors
answer
resources that can be changed in the short run
question
fixed factors
answer
resources that can't be changed in the short run
question
long run
answer
all factors of production being used by the firm can be changed
question
marginal product
answer
the additional output created by the increase of one unit of input
question
increasing marginal returns
answer
when marginal returns increase as inputs increase
question
law of diminishing returns
answer
marginal product will continue to decline as more workers are hired
question
average product
answer
reflects the law of diminishing returns
question
AP product
answer
Total output/ # workers
question
ways MP affects AP
answer
1. MP>AP, +1 input causes AP to increase
2. MP<AP, +1 input causes AP to decrease
2. MP<AP, +1 input causes AP to decrease
question
MP=0
answer
Total product is at its maximum
question
MP= negative
answer
Total product is falling
question
AP=MP
answer
AP is at its maximum
question
level of technology
answer
dictates the marginal and average product function for the firm
question
fixed costs
answer
don't change when output changes
question
examples of fixed costs
answer
lease; rent; payments; insurance; principal and interest on loans; garbage; utility bills
question
FC curve
answer
horizontal line
question
variable cost
answer
change as the level of output changes; increases when output increases
question
examples of VC
answer
number of workers; raw material used in the production process
question
total costs formula
answer
= total fixed costs (+) total variable costs
question
total cost
answer
shows a firm's short-run cost structure
question
TC
answer
=FC+VC
question
variable cost curve
answer
shows the relationship between the firm's VC costs and the level of the firm's output
question
total cost curve
answer
parallel to the VC curve; starts at the FC curve
question
marginal cost
answer
additional cost incurred when the business produces one more product
question
marginal cost formula
answer
change in total cost/ change in quantity; Q always= 1; difference between successive total costs
question
Marginal cost curve
answer
decreases then eventually rises with output due to the law of diminishing marginal returns
question
average fixed costs
answer
FC/(Q or Output)
question
AFC curve
answer
falls as output rises -> "spreading the overhead"
question
average variable cost
answer
VC/(Q or O)
question
AVC curve
answer
similar in shape to VC curve; reflects the law of diminishing returns
question
average total cost
answer
AFC + AVC; TC/Q
question
distance between ATC curve and AVC curve
answer
AFC
question
when MC curve crosses the AVC curve
answer
AVC curve at its minimum
question
relationship between ATC and MC
answer
ATC declines as long as MC is below it; ATC rises as MC is above it
question
relationship between AVC and MC
answer
AVC declines when MC is below it; rises when MC is above it
question
long run cost
answer
all factors are variable and therefor all costs are variable; used to plan for the future
question
long run average total cost curve
answer
drawn with the short run average total cost curve at each level of output; connects the lowest portions of the short-run curves
question
cost envelope
answer
LRATC curve because it "hold" the lowest possible production cost at each level of output in the long run
question
economies and diseconomies of scale
answer
influence resource allocations and output decisions in the long run
question
economies of scale
answer
when a firm's growth leads to lower production costs per unit
question
effect of economies of scale
answer
the larger the economies of sale, the greater the advantage to a large firm
question
disadvantages of economies of scale
answer
smaller businesses may struggle to compete; larger firms that are fewer in number
question
constant returns to scale
answer
when firms tend to see their long-run average cost curve flatten out;
question
diseconomies of scale
answer
when a firm's growth leads to higher production costs per unit; set in when a firm continues to grow
question
why is the LRATC "U" shaped
answer
1. economies of scale-> slopes downward
2. constant returns to scale-> flattens out/ horizontal
3. diseconomies of scale -> slopes upward
2. constant returns to scale-> flattens out/ horizontal
3. diseconomies of scale -> slopes upward
