When an economist says that the demand for a product has increased, this means that
consumers are now willing to purchase more of this product at each possible price.
There will be a surplus of a product when
consumers want to buy less than producers offer for sale.
An increase in the price of a product will reduce the amount of it purchased because
consumers will substitute other products for the one whose price has risen.
With a downsloping demand curve and an upsloping supply curve for a product, a decrease in resource prices will
decrease equilibrium price and increase equilibrium quantity.
If X is a normal good, a rise in money income will shift the
demand curve for X to the right.
If Z is an inferior good, an increase in money income will shift the
demand curve for Z to the left.
Demand-side market failures occur when
demand curves don't reflect consumers' full willingness to pay for a good or service.
People enjoy outdoor holiday lighting displays and would be willing to pay to see them, but can't be made to pay. Because most people who put up lights are unable to charge others to view them, they don't put up as many lights as people would like. This is an example of a
demand-side market failure.

increase, quantity demanded to decrease, and quantity supplied to increase.
A government subsidy to the producers of a product
increases product supply.
Broadly defined, competition involves
independently acting buyers and sellers and freedom to enter or leave markets.
College students living off-campus frequently consume large amounts of ramen noodles and boxed macaroni and cheese. When they finish school and start careers, their consumption of both goods frequently declines. This suggests that ramen noodles and boxed macaroni and cheese are
inferior goods.

is nonrivalry and nonexcludability.
Answer the question on the basis of the data given in the following production possibilities table. Refer to the table. For these data, the law of increasing opportunity costs is reflected in the fact that
larger and larger amounts of capital goods must be sacrificed to get additional units of consumer goods.
One reason that the quantity demanded of a good increases when its price falls is that the
lower price increases the real incomes of buyers, enabling them to buy more.
Refer to the diagram. A decrease in quantity demanded is depicted by a
move from point y to point x.
Refer to the diagram. An increase in quantity supplied is depicted by a
move from point y to point x.
Refer to the diagrams for two separate product markets. Assume that society's optimal level of output in each market is Q0 and that government purposely shifts the market supply curve from S to S1 in diagram (a) on the left and from S to S2 in diagram (b) on the right. We can conclude that the government is correcting for
negative externalities in diagram (a) and positive externalities in diagram (b).
For most products, purchases tend to fall with decreases in buyers' incomes. Such products are known as
normal goods.

product; resource
Economists contend that most economic decisions are
purposeful.
Answer the question based on the given supply and demand data for wheat. If price was initially $4 and free to fluctuate, we would expect the
quantity of wheat supplied to decline as a result of the subsequent price change.
If we say that a price is too high to clear the market, we mean that
quantity supplied exceeds quantity demanded.
The term "quantity demanded"
refers to the amount of a product that will be purchased at some specific price.
Refer to the diagram. Arrows (1) and (2) represent
resources and goods, respectively.
An effective price floor on wheat will
result in a surplus of wheat.
Refer to the diagram. A decrease in demand is depicted by a
shift from D2 to D1.

smaller in Duckistan than Herbania.
Refer to the diagram for athletic shoes. If the current output of shoes is Q3, then
society should produce fewer shoes to achieve the optimal allocation of resources.
Refer to the diagram for athletic shoes. If the current output of shoes is Q3, then
society would consider additional units of shoes to be less valuable than alternative products.
A leftward shift of a product supply curve might be caused by
some firms leaving an industry.
Refer to the diagram, which shows demand and supply conditions in the competitive market for product X. Given D0, if the supply curve moved from S0 to S1, then
supply has decreased and equilibrium quantity has decreased.
If government set a minimum price of $50 in the market, a
surplus of 21 units would occur.
Refer to the diagrams for two separate product markets. Assume that society's optimal level of output in each market is Q0 and that government purposely shifts the market supply curve from S to S1 in diagram (a) on the left and from S to S2 in diagram (b) on the right. The shift of the supply curve from S to S1 in diagram (a) might be caused by a per-unit
tax on the producers of this product.
Refer to the provided supply and demand graph for a product. In the graph, line S is the current supply of this product, while line S1 is the optimal supply from the society's perspective. One solution to this externality problem is to
tax producers by the amount DE per unit.
Refer to the diagram, in which S is the market supply curve and S1 is a supply curve comprising all costs of production, including external costs. Assume that the number of people affected by these external costs is large. If the government wishes to establish an optimal allocation of resources in this market, it should
tax producers so that the market supply curve shifts leftward.
The production possibilities curve tells us
the combinations of two goods that can be produced with society's available resources.
When the price of a product falls, the purchasing power of our money income rises and thus permits consumers to purchase more of the product. This statement describes
the income effect.
Because of the free-rider problem,
the market demand for a public good is nonexistent or understated.
If there is a shortage of product X, and the price is free to change,
the price of the product will rise.
Allocative efficiency refers to
the production of the product mix most wanted by society.
At the point where the demand and supply curves for a product intersect,
the quantity that consumers want to purchase and the amount producers choose to sell are the same.
A negative externality or spillover cost occurs when
the total cost of producing a good exceeds the costs borne by the producer.
Productive efficiency refers to
the use of the least-cost method of production.
In a competitive market economy, firms select the least-cost production technique because
to do so will maximize the firms' profits
Which of the following most closely relates to the idea of opportunity costs?
trade-offs
Refer to the diagram. Flow 1 represents
wage, rent, interest, and profit income.
The optimal allocation of resources is found
where MB = MC.

If the demand curve for product B shifts to the right as the price of product A declines, then
A and B are complementary goods.
A and B are substitute goods, but A and C are complementary goods. If the cost of producing A decreases, then the demand for
B will decrease and the demand for C will increase.

"Consumer sovereignty" means that
buyers determine what will be produced based on their "dollar votes" for the goods and services offered by sellers.

diminishing marginal utility
Private property
encourages owners to maintain or improve their property to preserve or enhance value.
Refer to the competitive market diagram for product Z. Assume that the current market demand and supply curves for Z are D1 and S1. If there are substantial external benefits associated with the production of Z, then
government can improve the allocation of resources by subsidizing consumers of Z.
The "invisible hand" concept refers to the
guiding function of prices in a market system.
Unlike a private good, a public good
has benefits available to all, including nonpayers.
The production possibilities curve illustrates the basic principle that
if all the resources of an economy are in use, more of one good can be produced only if less of another good is produced.
A market is in equilibrium
if the amount producers want to sell is equal to the amount consumers want to buy.
