There are 96 producers in the perfectly competitive market of Queen Elizabeth II commemorative tea cosies. Of those 96, 70 each have the following short-run total cost curve: STC(Q) = 22.5 +0.1Q + 20Q, where Q is output (meaning each have short-run marginal cost curve SMC(Q) = 0.2Q +20). The remaining 26 each have the following short-run total cost curve: STC(Q) = 40 + 0.1Q (meaning each have the short-run marginal cost curve SMC(Q) = 0.2Q). a) Assuming all fixed costs are sunk in the short run, find each producer's short- run supply curve, and also the market supply curve. b) Assuming all fixed costs are nonsunk in the short-run, find each producer's short-run supply curve, and also the market supply curve. c) Assume again that all fixed costs are sunk in the short run. If the market de- mand curve is Q = 8990-300P, what is the short-run equilibrium price and quantity? d) Assume again that all fixed costs are nonsunk in the short run. If the market demand curve is again Q = 8990-300P, what is the short-run equilibrium price and quantity? e) Suppose that in the long run, all firms face the following total cost curve: TC(Q) = 600.625 +0.1Q (meaning each have the marginal cost curve MC(Q) = 0.2Q). As well, firm entry and exit is possible in the long run. Assuming market demand is Q = 8990-300P, how many producers will there be in the market in the long run?
