Document Summary

Let"s recall definition of perfectly competitive market: Total revenue for a competitive firm is interesting, compared to other types of firms that we will see later. They take price as given, they cannot affect price. Marginal revenue = change in tr/ change in q. So, for competitive firms, profit = ar = mr* Firm would be better off increasing production as the price they sell at (mr) is greater than the cost of that additional unit. This means the additional cost (mc) of the last unit is greater than the price at which the firm can sell it. If p < avc = shut down* Sunk costs -> costs a firm must pay even if they shut down. In the short run, fixed costs are sunk costs** If p>atc => firm is making short run profits. If atc > p > avc => firm operates at a loss in the short run. Long-run equilibrium: p=atc => zero economic profits.
