There is a competitive industry with an infinite number of potential firms. All firms have the same cost function c( q) = q^2 + 4. Industry demand is Q = 100 − 5p, where Q is total industry output and p is the output price. Let n denote the number of firms in the industry. Find the long-run equilibrium number of firms (n), price and quantity produced by each firm.
Industry X has a market demand curve given by the equation P = 100 – Q/100, where P is the market price, and Q is industry-wide output.100 perfectly competitive firms currently operate in industry X. Each of these firms has a total cost function given by TC = 100 + 10q + q2, where q is the output of the individual firm, and thus MC = 10 + 2q.
(a) Would any of the firms in industry X ever shut down in the short run? If so, what is the cut-off price required for firms to operate – Shut-down price?
(b) What is the market output in the short run? What is the market price? How much do individual firms produce? Do firms earn economic profits? [Hint: you will first need to work out the industry supply curve.]
*Note: when finding answers for this question online, they wrote to first find the AVC function for part a but I don't understand how they found that AVC function first- any help would be much appreciated!
Consider a competitive industry with a market demand curve of P = 252 – Q, where P is market price and Q is the quantity demanded in the market. Each firm in the industry has a cost function of TC = 196 + q2, if q > 0 where q is output of the individual firm (TC = 0 if q = 0). The market is initially in long-run equilibrium. The government decides to regulate the industry by issuing licences to all firms currently in the industry, and not to allow any further entry by other firms without a licence. That is, the number of licences is fixed, and entry requires that an existing licence holder sells their licence to the potential entrant, leaving the number of firms producing in the industry fixed. Subsequent to the introduction of this regulation, the market demand curve shifts to P = 432 – Q. What is the value of the licence?
