In economics, the pleasure, happiness, or satisfaction received from a product.
Joe sold gold coins for $1000 that he bought a year ago for $1000. He says, "At least I didn't lose any money, because he could have received a 3 percent return on the $1000 if he had bought a bank certificate of deposit instead of the coins. The economist's analysis in this case incorporates the idea of:
In response to the terrorist attacks of September 11, 2001, the government decided to allocate more resources toward defense goods. The government's decision reflects their assessment that:
The marginal benefits of additional defense goods outweighed the marginal cost.
Economics may best be defined as the:
Social science concerned with how individuals, institutions, and society make optimal choices under conditions of scarcity.
Are generalizations based on a careful observation of facts.
The term "ceteris paribus" means:

persists because economic wants exceed available productive resources.
The four factors of production are:
land, labor, capital, and entrepreneurial ability.

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.
Which of the following will not produce an outward shift of the production possibilities curve?
the reduction of unemployment.
A nation's production possibilities curve is bowed out from the origin because:
resources are not equally efficient in producing every good.
Refer to the above table. If the economy is producing at a production alternative C, the opportunity cost of the tenth unit of consumer goods will be.
1/3 of a unit of capital goods.
Refer to the above table. As compared to production alternative D, the choice of alternative C would:
tend to generate a more rapid growth rate.
Assume that a change in government policy results in greater production of both consumer goods and investment goods. We can conclude that:
the economy was not empoying all of its resources before the policy change.
Assume an economy is operating at some point on its production possibilities curve, which shows civilian and military goods. If the output of military goods is increased, the output of civilian goods:
must be decreased.
Refer to the above diagram. Other things equal, this economy will achieve the most rapid rate of growth if:
it chooses point A.

The pleasure, happiness, or satisfaction obtained from consuming a good or service.
Comparisons of marginal benefits and marginal costs, usually for decision making.
Observing real-world behavior and outcomes. Based on those observations, formulating a possible explanation of cause and effect (hypothesis). Testing this explanation by comparing the outcomes of specific events to the outcome predicted by the hypothesis. Accepting, rejecting, and modifying the hypothesis, based on these comparisons. Continuing to test the hypothesis against the facts. If favorable results accumulate, the hypothesis evolves into a theory.
A statement about economic behavior or the economy that enables prediction of the probable effects of certain actions.
"Other-Things-Equal" Assumption. A prediction, or a statement about causal or logical connections between two states of affairs, is qualified by ceteris paribus in order to acknowledge, and to rule out, the possibility of other factors that could override the relationship between the antecedent and the consequent.

The study of the performance of national economies and the policies that governments use to try to improve that performance
A person who takes fewer hours to perform a task compared to another

Efficiency is an important social goal because when the economic pie grows larger, everyone can have a larger slice.
(AKA "No-Cash-on-the-Table" Principle): A market in equilibrium leaves no unexploited opportunities for individuals but may not exploit all gains achievable through collective action

Reveals the relationship between the various prices of corn and the quantity of corn a particular consumer would be willing and able to purchase each of these prices.
Law of Demand
If supply is held constant, an increase in demand leads to an increased market price, while a decrease in demand leads to a decreased market price.
Diminishing Marginal Utility
the law that for a single consumer the marginal utility of a commodity diminishes for each additional unit of the commodity consumed.
indicates that a lower price increases the purchasing power of a buyer's money income, enabling the buyer to purchase more of the product than before.
suggests that at a lower price buyers have the incentive to substitute what is now a less expensive product for other products that are now relatively more expensive.
a downward slope that reflects the law of demand--people buy more of a product, service, or resource as its price falls.
Determinants of Demand
When price changes, quantity demanded will change. That is a movement along the same demand curve. When factors other than price changes, demand curve will shift. These are the determinants of the demand curve, i.e., income, consumer preferences, number of buyers, and prices of related goods.
Products whose demand varies directly with money income.
Goods whose demand varies inversely with money income.
is one that can be used in place of another good.
is one that is used together with another good.
Change in Demand
is a shift of the demand curve to the right (an increase in demand) or to the left (a decrease in demand). It occurs because the consumer's stte of mind about purchasing the product has been altered in response to a change in one or more of the determinants of demand.
Change in Quantity Demanded
is a movement from one point to another point--from one price-quantity combination to another--on a fixed demand curve. The cause of such a change is an increase or a decrease in the price of the product under consideration.
is a schedule or curve showing the various amounts of a product aht producers are willing and able to make available for sale at each of a series of possible prices during a specific period.
It shows the quantities of corn that will be supplied at various prices, other things equal.
Law of Supply
A supply schedule tells us that, other things equal, firms will produce and offer for sale more of their product at a high price than at a low price. This, again, is basically common sense.
A graph showing the hypothetical supply of a product or service that would be available at different price points.
Determinants of Supply
are (1) resource prices, (2) technology, (3) taxes and subsidies, (4) prices of other goods, (5) producer expectations, and (6) the number of sellers in the market.
Change in Supply
means a change in the schedule and a shift of the curve. In increase in supply ***** the curve to the right; a decrease in supply shifts it to the left. The cause of a change in supply is a change in one or more of the determinants of supply.
Change in Quantity Supplied
is a movement from one point to another on a fixed supply curve. The cause of such a movement is a change in the price of the specific product being considered.
the quantitiy at which the intentions of buyers and sellers match, so that the quantity demanded and the quantity supplied are equal.
the quantity at which the intentions of buyers and sellres match, so that the quantity demanded and the quantity supplied are equal.
quantity demanded exceeds quantity supplied at that price.
the production of any particular good in the least costly way.
the particular mix of goods and services most highly valued by society (minimum-cost production assumed).
is a government-imposed limit on how high a price is charged for a product. Governments intend price ceilings to protect consumers from conditions that could make necessary commodities unattainable.
is a government- or group-imposed limit on how low a price can be charged for a product.
