question
AP
answer
(Average Product)- output per unit of labor AP= total product/change in labor input
question
TP
answer
(Total Product)- total quantity or output of a particular good or service produced.
question
MP
answer
(Marginal Product)- the extra output or added product assosiated with adding a unit of a variable resource
MP=change in total product/change in labor input
MP=change in total product/change in labor input
question
Economic Profit
answer
Revenue-explicit costs-implicit costs
question
Accounting Profit
answer
Revenue-total explicit costs
question
Normal Profit
answer
...
question
TC
answer
(total costs) total fixed(TFC)+total variable costs(TVC)
question
AFC
answer
(average fixed cost) AFC=TFC/Q
question
AVC
answer
(average variable costs) AVC= TVC/Q
question
ATC
answer
(average total costs) ATC= AFC+AVC
question
MC
answer
(marginal cost) the additional cost of producing one more unit of output MC= change in TC/change in Q
question
Economies of Scale
answer
the downsloping part of a long run ATC curve and mnimum ATC occurs at low out put
question
Diseconomies of Scale
answer
difficulty controlling, coordinating a firms opperations because it has become too big.
question
Constant returna to scale
answer
long run average cost does not change
question
MES
answer
(minimum efficient scale) lowest level of output at which a firm can minimize long-run average costs.
question
Monopoly
answer
average total cost is minimized when only one firm produces a particular good or service.
question
Pure Competition
answer
a large number of firms producing a standardized product with each output being identical.
question
MR in pure competitoin ='s
answer
PRICE, becuse the producer isa price take.
question
In the SHORT RUN a firm with maximize profit when:
answer
MR(marginal revenue)=MC(marginal cost)
question
In a PURELY COMPETITIVE firm P(price)=
answer
MC(marginal Cost) becuase demand is perfectly elastic at market price so MR(marginal Revenue)=Price
question
To maximize profit or minimize loss a firm should produce at:
answer
the point where P=MC(marginal cost)
Because: if you multiple price ex:(131) by output (9) TR = 1179 an if ATC at 9 units is 97.78 then that gives us TC of 880. the difference is 1179-880=299 economic profit.

question
Short-Run Loss
answer
where P(price) still exceeds the minimum AVC(avergae variable costs)
question
Short-Run Shut down
answer
when P(price falls below minimum AVC. There is not level of output which the firm can produce that is less then their fixed cost.
question
Equilibrium Price
answer
MR=MC
question
Productive efficiency (LONG RUN)
answer
Price will settle at minimum average total cost, P(MR)=minimumATC.
The good or service is being produced in the least costly way possible forced by pure competition.

question
When MC&ATC&MR(P) meet in the LONG RUN
answer
minimum ATC (normal profit)
