Formulae
- Name
Profit Maximization Condition
- Note
Applies to all market structures for profit-maximizing firms.
- Expression
Marginal Revenue (MR) = Marginal Cost (MC)
- Name
Perfect Competition Price-Output Equilibrium
- Note
Firms are price-takers.
- Expression
Market Demand = Market Supply => Equilibrium Price (P) = Firm's MR = Firm's AR
- Name
Monopoly/Monopolistic Competition Price-Output Equilibrium
- Note
Firms are price-makers.
- Expression
MR = MC => Determine Quantity (Q); then find Price (P) on the Demand Curve
- Name
Average Revenue
- Note
Same as price for all market structures.
- Expression
AR = Total Revenue (TR) / Quantity (Q) = Price (P)
- Name
Marginal Revenue
- Note
MR curve lies below the AR (Demand) curve for firms with market power.
- Expression
MR = Change in TR / Change in Q
Prerequisites
Basic understanding of demand and supply.
Concept of cost (Fixed, Variable, Marginal, Average).
Understanding of revenue (Total, Average, Marginal).
Common mistakes
Confusing price-taker and price-maker firms.
Assuming firms in oligopoly act independently.
Overlooking the role of product differentiation in monopolistic competition.
Incorrectly applying the P=MR=AR rule to non-perfectly competitive markets.
