what are the four fundamental questions to ask in any economic system?

1. what goods and services will be produced? 2. how will the goods and services be produced? 3. who will get the goods and services? 4. how will the system promote progress?

Explain how changes in supply and demand affect equilibrium prices and quantities.

Changes in supply and demand affect equilibrium prices and quantities because they determine these things. For instance, an increase in demand would also raise equilibrium price and equilibrium quantity. Changes in supply would either reduce equilibrium price and increase equilibrium quantity, or vice versa.

Identify what government-set prices are and how they can cause product surpluses and shortages.

Government-set prices are when the government decides that prices are either unfairly high to buyers or unfairly low to sellers. This can cause product surplus and shortage because of the prices not going along with supply and demand. Either the quantity supplied exceeds quantity demanded, or quantity demanded exceeds quantity supplied.

Relate how supply and demand interact to determine market equilibrium.

Supply and demand interact to determine market equilibrium because of equilibrium price and equilibrium quantity. Supply and demand are the determinants of market equilibrium because when the amount demanded and the amount supplied are equal, that is market equilibrium.

List the categories of scarce resources and delineate the nature of the economizing problem.

The categories are: land, labor, capital, and entrepreneurial ability. The economic problem has to do with resources and the scarcity of them. Where is the best place in society to put these resources when there are few of them? This is why society has an economic problem as a whole.

Describe the role of the economics theory in economics.

The economic theory is a statement of a cause-effect relationship; when accepted by nearly all economists, an economic principle. The role of this theory in economics is that everything having to do with the economy has a cause and an effect on society and the individual.

Are the goods that businesses offer for "free" to consumers also free to society? Select one: a. Yes, because the individual consumer does not have to pay for them. b. Yes, because the marginal benefit is greater than the marginal cost. c. No, because scarce resources were used to produce the free goods. d. No, because society does not assign a value to free goods.

c. no because scarce resources were used to produce the free goods

characteristics: private property, freedom of enterprise and choice, self-interest, competition, markets and prices, technology and capital goods, specialization, use of money, and active but limited government

distinguish between goods that are complements and substitutes

complements are like bread and butter. substitutes are like pen and pencil

d. individuals and communities have to make choices from among alternatives

(t/f) U.S. CEOs are overpaid and something should be done about it.

depends on the situation, if they worked hard then they deserve it. but if the people under them work hard and are paid little, then the CEO does not deserve it

Among competing issues, the most important concern of economics is with the:

efficient use of limited productive resources to satisfy economic wants.

what are the determinants of demand?

factors other than price that locate the position of a demand curve

what are determinants of supply?

factors other than price that locate the position of the supply curve

(t/f) economics is the study of abundance

false, economics is the study of scarcity. Although it could be true because of the abundance of wants.

(t/f) in the world we live in, there are unlimited resources, but limited wants

false, there are limited resources but unlimited wants

(t/f) in economics, "rational self-interest" is a bad thing

false. rational self-interest is a good thing because a lot of the time it helps others

what are some facts about U.S. businesses?

firms that purchase resources and provide goods and services to the economy, or commercial establishments that attempt to earn profits for their owners by offering goods and services for sale

what happens when the government interferes in the functioning of supply and demand?

government occaisonally concludes that changes in supply and demand have created prives that are unfairly high to buyers or unfairly low to sellers. government may then place legal limits on how high or low a price may go. shortage/surplus

what does "capital" mean?

human-made resources (buildings, machinery, and equipment) used to produce goods and services

how do advances in technology affect the economy?

it betters and improves the methods of production

the U.S. economic system is a command system. Why or why not?

it is not a command system, but a market system since things are privately owned and operated

what are capital goods?

items that are used to produce other goods and therefore do not directly satisfy consumer wants

what is law of demand and supply?

law of demand is an increase in a products price will reduce the quantity demanded. law of supply is as price rises, quantity rises

the basic economic problem is essentially one of deciding how to make the best use of:

limited resources to satisfy unlimited economic wants

what is marginal thinking?

marginal thinking is marginal benefits compared to marginal cost

what is market demand and supply?

market demand is the deciding factor of a price. supply is a schedule showing the amounts of a good or service that sellers will offer at various prices

what is market supply?

market supply is derived from individual supply, the supply and demand of all individuals

you go to your bank and you say "**** this line" and leave. what economic decision did you just make?

opportunity cost

what are private and public goods?

private goods are goods that people individually buy and consume and that private firms can profitably provide because they keep people who do not pay from receiving the benefits. public goods are goods that everyone can simultaneously consume and from which no one can be excluded, even if they do not pay

what are consumer goods?

products and services that directly satisfy consumer wants

as a student of economics, when you speak of scarcity, you are referring to the ability of society to:

satisfy economic wants given economic resources

discuss the concepts of shortage and surplus in the context or supply and demand

shortage is when quantity demanded of a product exceeds quantity supplied surplus is when quantity supplied exceeds quantity demanded

describe society's economic problem

society needs to make choices because economic wants are unlimited, but the means (income, time, resources) for satisfying those wants are limited. Same issues as individuals

explain the production possibilities model

society uses its scarce resources to provide goods and services. the alternatives and choices it faces can be best understood through a macroeconomic model of production possibilities. to keep things simple, we assume -full employment: the economy is employing all of its available resources -fixed resources: the quantity and quality of the factors of production are fixed -fixed technology: the state of technology (the methods used to produce output) is constant -two goods: the economy is producing only two goods: food products and manufacturing equipment

how do you achieve an efficiently functioning market?

to achieve an efficiently functioning market, the demand curve in the market must reflect consumers' full willingness to pay and the supply curve in the market must reflect all the costs of production

(T/F) a production possibilities frontier is a model that illustrates the combination of outputs that a society can produce if all of its resources are being used efficiently

true

(T/F) comparative advantage refers to the situation where an individual, business, or country can produce at a lower opportunity cost than a competitor can

true

(T/F) in a market economy, resources are allocated among households and firms with little or no government interference

true

(t/f) a budget line shows combinations of two things a person can buy at specific prives and income

true

(t/f) there are two general types of economic systems: command and market systems

true

entrepreneurial ability is an economic resource, why?

true, because entrepreneurial ability helps others, society, and the production of goods

(t/f) marginalism involves looking at extra benefits or costs of a decision

true, marginal means extra or additional

the satisfaction or pleasure one gets from consuming a good or service is called:

utility

the utility of a specific product:

varies from person to person using the product

when are we sure we have achieved optimal allocation?

when we have achieved marginal benefit = marginal cost
