indifference curve

a curve that shows consumption bundles that give the consumer the same level of satisfaction

a good that consumers demand less of when their incomes increase

normal good

a good that consumers demand more of when their incomes increase

Suppose that the equilibrium price in the market for widgets is $5. If a law increased the minimum legal price for widgets to $6, producer surplus

might increase or decrease.

As a result of a decrease in price,

new buyers enter the market, increasing consumer surplus

If the price of pasta increases and a consumer buys more pasta, we can infer that

pasta is an inferior good, and the income effect is greater than the substitution effect.

$80, and this figure represents the surplus that is lost because the tax discourages mutually advantageous trades between buyers and sellers.

Matthew and Susan are both optimizing consumers in the markets for shirts and hats, where they pay $100 for a shirt and $50 for a hat. Matthew buys 4 shirts and 16 hats, while Susan buys 6 shirts and 12 hats. From this information, we can infer that Matthew's marginal rate of substitution is _____ hats per shirt, while Susan's is _____.

The effects of free trade can be determined by

comparing the domestic price without trade to the world price

Jen values her time at $60 an hour. She spends 2 hours giving Colleen a massage. Colleen was willing to pay as much at $300 for the massage, but they negotiate a price of $200. In this transaction,

government's tax revenue.

has a large deadweight loss.

When a market is in equilibrium, the buyers are those with the ________ willingness to pay and the sellers are those with the ________ costs.

highest, lowest

Peanut butter has an upward-sloping supply curve and a downward-sloping demand curve. If a 10 cent per pound tax is increased to 15 cents, the government's tax revenue

increases by less than 50 percent and may even decline.

Eggs have a supply curve that is linear and upward-sloping and a demand curve that is linear and downward-sloping. If a 2 cent per egg tax is increased to 3 cents, the deadweight loss of the tax

increases by more than 50 percent.

The infant-industry argument

is based on the belief that protecting industries when they are young will pay off later.

Darius buys only lobster and chicken. Lobster is a normal good, while chicken is an inferior good. When the price of lobster rises, Darius buys

less lobster and more chicken

market power and externalities

Motor oil and gasoline are complements. If the price of motor oil increases, consumer surplus in the gasoline market

may increase, decrease, or remain unchanged.

Producing a quantity larger than the equilibrium of supply and demand is inefficient because the marginal buyer's willingness to pay is

positive but less than the marginal seller's cost.

When a nation opens itself to trade in a good and becomes an importer

producer surplus decreases, but consumer surplus and total surplus both increase.

When a country allows trade and becomes an exporter of a good

producers of the good are better off, and consumers of the good are worse off

A supply curve can be used to measure producer surplus because it reflects

sellers cost

Explain how sellers' costs, producer surplus, and the supply curve are related.

The Sellers cost is how much they pay to obtain a good. The producers surplus is the amount they pay minus the cost of providing it. The supply curve measures this amount by looking at the area above the supply curve.

The main difference between imposing a tariff and handing out licenses under an import quota is that a tariff increases

government revenue.
