Total Cost =
(Two Answers )
Total Fixed Cost + Total Variable Cost (TC = TFC + TVC)
Or
AC x Q (TC = Average Cost x Quantity)
Total Fixed Cost (TFC) =
(2 solutions)
TFC = TC - TVC (total cost - total variable cost)
Or
TFC = AFC x Q (average fixed cost x quantity)
Total Variable Cost (TVC) =
(2 solutions)
TVC = TC - TFC (Total Cost - Total Fixed Cost)
Or
TVC = AVC x Q (Average Variable Cost x Q)
Average Cost (AC) =
(2 solutions)
AC = TC / Q (Total Cost / Q)
Or
AC = AVC + AFC (Average Fixed Cost + Average Variable Cost)
Marginal Cost (MC) =
MC = ∆TC / ∆Q
(Change in Total Cost / Change in Quantity)
Average Product (AP) =
AP = TP / Q of LABOUR
(Total Product / Quantity of Labour)
Marginal Product (MP) =
MP = ∆TP / ∆Q of LABOUR
(Change in Total Product / Change in Quantity of Labour)
Total Revenue (TR) =
TR = P x Q
(Price x Quantity)
Average Revenue (AR) =
AR = TR / Q
(Total Revenue / Quantity)
Marginal Revenue (MR) =
MR = ∆TR / ∆Q
(Change in Total Revenue / Change in Quantity)
How can you use Total Revenue (TR) simplify the equation for Average Revenue (AR)?
TR = P x Q
AR = TR / Q
AR = (P x Q) /Q
AR = P
(Q cancels out)
Profit =
Profit = TR - TC
(Total Revenue - Total Cost)
Supernormal Profit =
SN P = AR > AC
(Average Revenue > Average Cost)
SUBNORMAL Profit =
SN P = AR < AC
(Average Revenue < Average Cost)
Profit Maximisation occurs
MR = MC
(Marginal Revenue = Marginal Cost)
M = Most Money
Revenue Maximisiation =
MR = 0
(Marginal Revenue = 0)
Meaning of ,
AC = AR (Average Cost = Average Revenue)
- Normal Profit
- Sales Maximisation
- Break Even (no economic profit or loss)
- Entry Limit Price (takes way incentive joining the market)
Allocative Efficiency is where …
(3 solutions)
D = S (Demand = Supply)
MSB = MSC (Marginal Social Benefit = Marginal Social Cost)
P = MC (Price = Marginal Cost)
Productive Efficiency occurs …
(2 solutions)
Minimum Point on AC curve.
AC = MR (Average Cost = Marginal Revenue)
X-efficiency occurs …
At ANY point on the AC (average cost) curve.
