###### PLAY
The concept of scarcity, as used by economists, refers to
A situation in which the available resources are not enough to satisfy the wants of the people.
An important implication of scarcity is that
People must make a choice.
The opportunity cost of a choice is the
Value of the next best activity not chosen.
The opportunity cost of attending college
Includes the lost wages that would have been earned if the student had not attended college.
When the economy is in recession, jobs are generally harder to find and more people go to college. We can conclude that the opportunity cost of
Going to college decreases when the economy is in recession.
According to the law of demand, if the price of compact disks decreased (ceteris paribus) the
Quantity demanded of compact disks would increase.
Suppose you observe that taxi fares per trip increased when more commuters took taxis. What is the best possible explanation?
The price of gasoline went up.
According to the law of demand, one way to reduce the amount of tobacco consumption is to
Raise the price of tobacco.
What will increase the demand for a normal good?
An increase in consumer income.
Consider the market for pop music played on compact disks. If there is a decrease in the number if pop music programs broadcast on radio, we can expect
The demand for compact disks to increase.
Suppose that Sunny D is an inferior good. What is true given an increase in consumer income?
A leftward shift in the demand curve of Sunny D.
Coffee and tea are substitutes so that if the price of tea increases, the
Demand for coffee increases.
If the price of product X falls and this causes the demand for product Y to shift to the right, then we can conclude that X and Y are
Complements.
If an increase in the price of product X causes an increase in the demand for product Y, we can conclude that
They are substitutes.
What will not cause the demand for ice cream to change?
A change in the price of ice cream.
According to the law of supply, if the price of personal computers increased, (ceteris paribus)
The quantity supplied of personal computers would increase.
What would not affect the supply of automobiles?
An increase in the price of motor oil.
Suppose all blue collar workers receive a substantial pay increase. What will happen in the product markets that employ these workers?
Supply will decrease.
Market equilibrium occurs when the
Quantity supplied equals quantity demanded.
If quantity supplied is less than quantity demanded, then
There is a shortage in the market.
If there is a surplus of a product, we can conclude that
The products prices is above equilibrium.
If price is below equilibrium
Quantity demanded exceeds quantity supplied, and a shortage exists.
The U.S. surgeon general warns that animal fat in the diet is unhealthy. With the discovery that longhorn beef cattle have little body fat, you would expect
Ranchers to be more willing to produce longhorn cattle as the price rises.
If it is discovered that using a smartphone regularly causes brain cancer, then in the market for smartphones
Equilibrium price and equilibrium quantity will fall.
What is the most likely reason for the increase in the price of roses on Valentines Day?
An increase in the demand for roses.
If a technological improvement took place in the computer industry, we should expect to see the equilibrium price of computers to
Decrease and the quantity of computers sold to increase.
Suppose it is observed in a market that price has fallen but more product is being produced and sold. This could be caused by a(n)
Increase in supply.
When both supply and demand shift right at the same time
The change in equilibrium price cannot be predicted, but the change in equilibrium quantity can be predicted.
Suppose in a financial crisis, major automakers reduce their production of autos while consumers reduce their demand for autos. We can conclude with certainty that in the market of autos
The equilibrium quantity will decrease but the equilibrium price will increase, decrease or remain unchanged.
Suppose a war in the Middle East destroys many oil fields. This will cause a(n)
Increase in oil prices.
The high price of gasoline in the late-2000's was likely the result of
A decrease in the supply of gasoline along with an increase in the demand for gasoline.
A price ceiling would result in a(n)
Shortage.
A price floor would result in a(n)
Surplus.
If price changes from \$8 to \$12 and quantity demanded changes from 80 units to 40 units, the the price elasticity of demand is
1.67.
A product with an inelastic demand means that
Consumers are relatively insensitive to a change in the price of the product.
A product with an elastic demand means that
Consumers are relatively sensitive to a change in the price of the product.
If a 3% change in price results in a 1.5% change in quantity demanded, then the price elasticity of demand is ___ and demand is ___.
1/2, inelastic.
In the process of calculating the production of the economy in the U.S., what must be taken into account?
-The fact that some of the goods that people buy are shipped to the U.S. from abroad.

Sally has recently graduated from college and has bought a house that was built 50 years ago for \$100,000. She used a real estate agent to help her find and purchase the house, and the real estate agent received 6% of the value of the sale, or \$6,000, to be paid by the seller of the house. The value of GDP in this case would
Increase by \$6,000.
What is the correct ordering if we want to rank the four spending components, as a share of U.S. GDP in 2010, in descending (from highest to lowest) order?
Consumption, government purchases, investment, net exports.

-Used goods.
-Intermediate goods.

Investment, as defined in the text, refers to

20%.
The natural unemployment rate is the unemployment rate
When the real and potential GDP are equal.
Cyclical unemployment can best be described as the

The rate of increase in real GDP per capita.
The term per capita refers to
The population.
The average annual growth rate of the U.S. economy over the past 40 years has been about
3%.
Because of the increase in population over the past 40 years
The rate of increase in real GDP per capita has been less than the rate of increase in real GDP.
Over the past 40 year, the average rate of increase in U.S. real GDP per capita has been about
2%.
The increase in real GDP per capita over the past 40 years is closest to
\$22,000.
Over the past 40 years, real GDP per capita has roughly
Doubled.
The unemployment rate
Increases as real GDP decreases.
