The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible.
We have identical firms, each with a Total Cost curve of TC=358+q^2 and Marginal Cost curve MC=2q.
Market demand is Q=600-2P.
If the Marginal Cost for every firm decreases by $10 at every quantity, what is the short-run market price?
Hint: first find the number of firms by solving for the original LR equilibrium.
Firms in a perfectly competitive market are said to be “price takers”—that is, once the market determines an equilibrium price for the product, firms must accept this price. If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent?

What is the number of firms in the market in the long run equilibrium?arrow_forwardA perfectly competitive market is in a long-run equilibrium. Prices of variable inputs for the typical firm decrease. Describe what will happen in the short run, to the typical firm’s marginal costs, average fixed costs, average costs, profits, and production as the firm makes its choices. In each case, describe why those changes take place. Describe exactly why the firm decides to make changes. As part of that discussion, summarize what happens in the market and how those changes relate to the typical firm. You do not need to discuss why the changes take place in the market. Outline in several sentences what will happen in the long run to the typical firm and the market.arrow_forwardWhat is the equilibrium or profit-maximizing quantity of production for a perfectly competitive firm?arrow_forward
