Document Summary

Chapter 4: co(cid:374)su(cid:373)er a(cid:374)d producer surplus: how to measure benefits from being able to purchase a good ( consumer surplus). There is a corresponding measure (producer surplus) of the benefits sellers receive from being able to sell a good. It"s also a model of how much consumers and producers came from participating in that market. The gains from trade: total surplus: the total surplus generated in the market is the total net gain to consumers and producers from trading in the market. An efficient market performs four important functions: it allocate consumption of the good to the potential buyers the most value it, as indicated by the fact that they have the highest willingness to pay. It allocates sales to potential sellers who most value the right to sell the good, as indicated by the fact that they have the lowest cost.

7) Indicate whether each of the following statements is true or false, and explain why.

A. Producer surplus tends to fall as the supply curve becomes more elastic.

B. Consumer surplus tends to rise as demand becomes more elastic.

C. The market demand curve indicates the minimum price buyers are willing to pay at each level of production.

D. The market supply curve indicates the minimum price required by sellers as a group to bring forth production.

E. Consumer surplus is the amount that consumers are willing to pay for a given good or service above and beyond the amount actually paid.

The market for packets of cigarettes has been described by the following supply and demand functions:

Supply: P = 10 + 4Q Demand: P = 100 - 5Q where P is the price in dollars and Q is the quantity of packets of cigarettes per month (in thousands).

Part A) Construct a graph of supply and demand for this market showing all intercepts. What are the equilibrium prices and quantities? Show these on your graph.

Part B) At the market equilibrium price, what would be the total monthly revenue?

Part C) Calculate consumer surplus at the market equilibrium and indicate this surplus as an area on your diagram.

Part D) Calculate producer surplus at the market equilibrium and indicate this surplus as an area on your diagram.

Part E) Assume that a per-unit tax of $9.00 per packet of cigarettes is imposed by the government on the suppliers of cigarettes. Depict this on your demand and supply diagram. (Hint: the new tax inclusive supply function will be: P = 19 + 4Q). What is the new market equilibrium quantity? What price will consumers now pay and what price will suppliers now receive?

Part F) How much is the government revenue from the tax on suppliers?

Part G) Calculate consumer surplus and producer surplus after the imposition of the tax and any deadweight loss associated with the tax. Indicate these surplus and tax revenue areas on your diagram. Explain what the deadweight loss represents.

Part H) Now assume that instead of imposing a per-unit tax of $9.00 per pack on the suppliers of cigarettes the government decides to apply the same per-unit tax of $9.00 on consumers. Depict this on your demand and supply diagram. (Hint: the new tax inclusive demand function will be: P = 91 - 5Q) What is the new market equilibrium quantity? What price will consumers now pay and what price will suppliers now receive? (5 marks)

Part I) How much is the government revenue from the tax on consumers? (1 mark)

Part J) Who bears the greatest burden of the tax in each case, producers or consumers? Does your answer depend on whether the tax is levied on producers or consumers?

I am really having difficulty understanding Part J - can that please be answered with some detail?

1. We can conclude that international trade is beneficial because, regardless of whether the country imports or exports a good, the overall increase in well-being outweighs the losses associated with trade.

Is the statement true or false?

2. Owners of firms in young industries should be willing to incur temporary losses if they believe that those firms will be profitable in the long run.€ This observation helps to explain why many economists are skeptical about the:

a. Unfair-competition argument.

b. Infant-industry argument.

c. national-security argument.

d. Jobs argument

3. Suppose that the U.S. has a comparative advantage in the production of spreadsheet software. As a result of opening up the market to international trade:

a. U.S. citizens benefit from lower software prices, increasing consumer surplus in the market.

b. U.S. producers benefit from higher software prices, increasing producer surplus in the market.

c. U.S. software producers are harmed since the price that these producers receive will decline as the price falls to the world price.

d. total surplus in this market will remain unchanged, as the decline in benefits received by software producers exactly balances the increase in benefits received by US software consumers.
