Common Mistakes

Confusing normal profit with abnormal profit: Normal profit is when TR = TC (zero economic profit). Abnormal profit is when TR > TC (positive economic profit). Don’t use them interchangeably.

Forgetting that perfect competition firms are price takers: In perfect competition, firms cannot set prices. They must accept the market price. Don’t assume firms can charge whatever they want.

Mixing up short-run with long-run equilibrium: In the short run, firms can earn abnormal profit or make losses. In the long run, entry/exit drives economic profit to zero. Don’t confuse the two timeframes.
