short run Flashcards
describe how profit is maximized in the short run using the total revenue/total cost or marginal revenue/marginal cost approaches
firm has fixed plant and maximize profits or minimizes losses by adjusting output
short run
output can be adjusted only through changes in amount of variable resources it uses
short run
the perfectly competitive firm makes two decisions in the short run
whether to produce or to shut down
-if the decision is to produce, what quantity to produce
firm should produce that output which maximizes its profits or minimizes its loss
where TR curve exceeds TC curve by largest amount
Short run profit maximization
two approaches
- total-revenue-total cost approach
- marginal revenue- marginal cost approach
total revenue total cost approach
- should the firm produce?
- what quantity should be produced?
- what profit or loss will be realized?
Produce in the short run if it can realize
1-a profit (or)
2-a loss less than its fixed costs
shutting down the firm does not eliminate all costs
fixed costs must be paid even if all output ceases
- if a firm makes losses, it cannot pay all its fixed costs and its variable costs
- the firm will lose less by shutting down if losses from continue production exceed fixed costs
MR = MC Rule
MR = MC profit maximization in all markets
Competitive markets maximize at….
P = MC
MR=MC rule
firm will maximize profits or minimize losses by producing at the point at which MR = MC in short run
Each firm adjusts output until price =
MC
each firms’ supply curve slopes upward as does market supply curve
..
higher product prices and MR encourage purely competetive firm to expand output
short run
changes in price of variable inputs or technology will shift MC curve
short run
