- 9.- A competitive firm reaches the minimum of the long-run average cost for y = 20 when it operates with the short-run cost function C = yi3-20yi2 + 100yi + 8000, where yi is the production of the firm. Then the long-run price equilibrium will be 500. If the government imposes a specific tax on output of 40 euros, what are the taxes collected by the government in the short-run and in the long-run, if the market demand is given by x = 2500 - 3p, where x is the quantity demanded by consumers and p is the price? Will the government collect more or less taxes in the long-run than in the short-run? Why?26.A firm operates in a perfectly competitive market and is producing at the profit-maximizing output.

- The market demand and supply equations for a product of a perfectly competitive industry. Qd=60-10P Qs=30+2.5P Where Q is quantity and P is price. Required: i.What is the equlibrium price and quantity? ii.Suppose that an increase in income resulted in the new demand equation Qd=80-10P What is the new equilibrium price and quantity? Suppose the government enact a legislation that imposes a price equivalent to the original equilibrium price.What kind of price legislation is this?Explain two implications of such a price control.Effect of tax on economic activity Suppose a per unit tax is imposed on perfectly competitive, profit-maximising firms that operate in an increasing-cost industry. What would happen to the market price, market output, the number of firms in the industry, output and profit of each firm in the short run? Illustrate on a graph. Assume that firms have upward-sloping marginal cost curve.Repeat your analysis for the long run. Compare the new long run equilibrium to the short run equilibrium and to the original long run equilibrium (before tax).Consider the market for electronic components ("chips") and assume that there is complete competition.1a) Graph the short-run market equilibrium in a supply-demand diagram. 1b) Due to entry restrictions, there are long waiting times and thus supply passports. Show what impact these supply bottlenecks have on the market for electric cars. For this purpose, graphically represent the situation with and without supply bottlenecks in a supply-demand diagram. Label the old and new market equilibrium as well as the new and old consumer and producer surplus. Be sure to include the necessary labels in your diagram. 1c) Since the effects on the market for electric cars related to the supply bottleneck are not desirable from a macroeconomic perspective, the government is considering intervening with economic policy measures. In your diagram from 1b), show why the effects addressed are not desirable from a macroeconomic perspective. Also explain this briefly in the text or annotated keywords.1d)…
