Responses to Economic Profits
Markets with excess profits attract resources
If a firm is covering its variable cost, it can stay
in the market in the SR
If a firm would like to stay in the market in the
LR, it must cover all costs: explicit and implicit
Markets in which firms are earning an economic
profit tend to attract additional resources
> More firms want to enter the market
> Market supply is expected to increase

costs
A firm that earns no more than a normal profit
(zero profits) has managed only to cover the
opportunity cost of the resources
> A firm that makes a positive economic profit earns
more than the opportunity cost of the invested
Markets in which firms are experiencing
economic losses tend to lose resources

minimum value of ATC, giving rise to positive

IAssumptions
> Firms are free to enter and leave the market
> Inputs can be purchased in any quantities at fixed
prices
> All firms employ similar standardized production
methods
ICondition: P<minimum ATC
> TR = 0.75 x 70 = $52,500
> TC = 1.05 x 70 = $73,500
• Total losses = $21,000
• Incentive for some firms to leave the market
• Supply decreases
• Price increase until incentive to leave the market
disappears
Final outcome: zero economic profit
> Do firms want zero economic profit?
• The zero economic profit is a consequence of price
movements following entry and exit of firms
