What is the law of demand?

As price increases, quantity demanded decreases

100

What is true at the market equilibrium?

Quantity supplied = quantity demanded

What is the price and quantity in the labor market? 

wage, jobs

What is a price ceiling? Give one example.

Regulation that says price can't be above a certain amount. Example: rent control

100

What does elasticity of demand measure?


Responsiveness of quantity demanded to a change in price

200

Explain the difference between an increase in supply and an increase in quantity supplied

An increase in supply means that more is supplied at every price - never due to a change in price. An increase in quantity supplied is movement along the supply curve (due to a change in price)

A severe freeze has once again damaged the Florida orange crop. What is the impact on equilibrium price and quantity of orange juice?

supply decreases 

200

How will a decrease in the price of oil impact the wages in the market for oil workers? 

wages will decrease because demand will decrease

200

What is the effect of a price control (floor or ceiling) on the total surplus (consumer + producer)

decreases

200

What is the shape of elastic supply curves (relative to inelastic supply curves)?

They are flatter

300

After widespread press reports about the dangers of contracting "mad cow disease" by consuming beef from Canada, what will be the likely economic effect on the U.S. market for beef from Canada?

Demand will shift to the left, and equilibrium quantity & price will decrease

300

What will be the effect on market price and quantity if demand and supply both increase?

quantity will increase, effect on price is ambiguous (depends on size of shift)

300

On April 1, 2009, in the middle of a recession, the government of the province of Ontario, Canada increased the provincial minimum wage from $8.75 to $9.50. What will the likely effect of this policy be?

There will be a surplus in the market for minimum wage jobs (Both the leftward shift in the labor demand curve and the higher minimum wage will lead to an increase in the unemployment rate.)

300

When is a price floor binding (meaning, it will have an impact on the market)?

when it is above the equilibrium price

300

What is the shape of a supply curve with constant elasticity? 

Straight line from the origin

If an increase in the price of Good X causes a decrease in the demand for Good Y, we can conclude that the two goods are:

complements

Many cooks view butter and margarine to be substitutes. If the price of butter rises, what will be the effect on the equilibrium price and quantity of margarine?

both the equilibrium price and quantity will rise.

If the United States allowed a greater quantity of immigration of foreign highly skilled workers, what will be the impact on the average wages of highly skilled employees?

Wages will decrease

Whenever there is a surplus at a particular price, the quantity sold at that price will equal:

the quantity demanded

400

If the supply curve for housing is perfectly inelastic, what will be the effect on price and quantity if demand decreases?

price will decrease and quantity will stay the same

500

Explain why the following statement is false: “In the goods market, no seller would be willing to sell for less than the equilibrium price.”

Firms will typically sell at any price that gives a nonnegative profit margin. Those with very low costs are making profits at the equilibrium price, but even if the price decreased, they would still sell as long as it was above their cost (the producer surplus would just be lower).

If the supply curve is P=2Q-2 and the demand curve is P=10-2Q, what is the equilibrium price and quantity?

3,3

Several types of economic events can cause a shift in labor demand, so that a higher or lower quantity of labor is hired at every salary or wage. List three of these events.

Changes in education and training, changes in technology, changes in government regulations
