For the following, please answer "True" or "False" and explain why. -While producing less than the competitive output decreases social welfare,the same cannot be said about producing more than the competitive output.

Suppose that all firms in a constant-cost industry have the following long-run cost curve: c(q)= 4q² + 100q + 100 The demand in this market is given by Qᴰ = 1280 - 2p.Suppose the number of firms in the market is restricted to 80 a.Derive the supply curve with this restriction.Find the market equilibrium price and quantity with the restriction. b.If firms are allowed to buy and sell these permits in an open market,what will be the rental price of permits? Will firm's that own permits make profit? Briefly explain. c.How much deadweight loss is generated by the permit system? Provide a graph showing the region of this deadweight loss. d.Suppose the government abandons the permit system and simply imposes a fixed fee on firms in the market.If the fee is set equal to the permit price you found in c.,what will be the equilibrium price,quantity,number of firms and deadweight loss?

For the following, please answer "True" or "False" and explain why. -Producer surplus is the sum of the profits earned by all firms in a market.

Suppose the market supply curve is p = 5Q.If price increases from 10 to 15,the change in producer surplus is

Suppose a consumer advocacy group has convinced legislators that vitamin pills should be free to consumers.Such a policy would enhance the health of the citizenry,they argue.Assuming a downward-sloping linear demand curve and a horizontal long-run supply curve,determine the resulting output and social welfare from such a policy.Compare this result to the competitive equilibrium.

For the following, please answer "True" or "False" and explain why. -If entry is limited due to a limited input,firms in that market earn long run economic profit.
