Document Summary

Chapter 7: reservation value - (willingness to pay value) Explain - there is really no definitive answer to this question since the issues surrounding efficiency and equity are the domain of normative economics, where subjective value judgements are made. The government, she reasons, can resolve the coordination problem of getting the agents in these markets to trade. Sofia"s reasoning is flawed because declining industries do not face a coordination problem. A coordination problem results when economic agents with coinciding interests cannot be brought together to trade. However, in this case, falling demand is responsible for the decline of industries like video rentals and print newspapers. It means that total surplus (or total welfare) will decrease as equity increases. This is because policies to increase equity (e. g. a price ceiling) cause deadweight loss (i. e. they decrease total welfare). In order to spread wealth more evenly throughout society, we must decrease total wealth.

True or False:

1. Consumer surplus is the buyer's willingness-to-pay minus the seller's opportunity cost of production.

2. If your willingness-to-pay for a hamburger is $3 and you paid $2, then your consumer surplus is $5.00

3. The opportunity cost of production for a seller includes the implicit cost of the seller's time.

4. The height of the supply curve at a selected quantity is the seller's opportunity cost of producing that marginal unit.

5. Total surplus (total well-being) is the seller's cost of production minus the buyer's willingness-to-pay.

6. The competitive market equilibrium outcome is efficient because it allocates the produced output to the buyers who place the highest value on the good

7. Producer surplus is the area above the supply curve and below the price.

8. The competitive market equilibrium outcome maximizes total surplus (total well-being)

9. Producing and consuming more of a good will always increase the total surplus(total well-being).

A) True
B) False

17.

A monopoly always makes an economic profit.

A) True
B) False

18.

		$0.40
		$0.75
		$0.67

2. In Market X, the external benefit of consumption is $5. In Market Y, the external cost of consumption is $10. Efficiency in both markets could be achieved by:

		a tax of $5 in Market X and a subsidy of $10 in Market Y.
		subsidizing both markets.
		taxing Market Y and subsidizing Market X.
		taxing both markets.

3.Economic theory suggests that a natural monopoly should be:
