What is a market?

An interaction between buyers and sellers.

What does the law of demand state?

As price falls, quantity demanded rises, and as price rises, quantity demanded falls.

What is a demand schedule?

A table showing the amount consumers are willing to purchase at different prices.

What factors can change demand?

Changes in consumer tastes, number of buyers, income, prices of related goods, and consumer expectations.

What is the law of supply?

As price rises, quantity supplied rises, and as price falls, quantity supplied falls.

What is a supply schedule?

A table showing the amount producers are willing to sell at different prices.

What is market equilibrium?

The point where the demand curve and supply curve intersect, determining the equilibrium price and quantity.

What is productive efficiency?

Producing goods in the least costly way using the best technology and the right mix of resources.

What is allocative efficiency?

Producing the right mix of goods that society values most highly.

What happens to equilibrium price and quantity when demand increases?

Price rises and quantity increases.

What happens to equilibrium price and quantity when supply increases?

Price falls and quantity increases.

What is a price ceiling?

A maximum price set below the equilibrium price, leading to shortages.

What is a price floor?

A minimum price set above the market price, leading to surpluses.

How do student loans affect tuition costs?

Increased demand from loans raises tuition costs; each $1 increase in loans raises tuition by 70 cents.

What is the rationing function of prices?

The ability of demand and supply forces to establish a price where buying and selling decisions are consistent.

What is a determinant of demand related to consumer income?

Changes in income can affect demand for normal and inferior goods.

What is a complementary good?

A good whose demand increases when the price of another good decreases.

What is a substitute good?

A good that can replace another good; demand for it increases when the price of the other good rises.

What is the impact of government-set prices on the market?

They can create shortages or surpluses, affecting market equilibrium.

What is the relationship between demand and consumer expectations?

Expectations about future prices and income can shift the demand curve.

What is the significance of the demand curve?

It visually represents the relationship between price and quantity demanded.

What is the significance of the supply curve?

It visually represents the relationship between price and quantity supplied.

What is economics?

The study of how individuals, businesses, governments, and societies make choices about using scarce resources to satisfy unlimited wants

What is scarcity?

The fundamental economic problem that resources are limited while human wants are unlimited.

What is purposeful behavior?

The idea that people make deliberate choices intended to achieve goals based on their preferences and available information.

What is utility?

The satisfaction or benefit a person receives from consuming a good or service.

What is opportunity cost?

The value of the next-best alternative that is given up when making a choice.

What is marginal cost?

The additional cost of doing or producing one more unit.

What is marginal benefit?

The additional benefit received from doing or consuming one more unit.

What is the basic marginal decision-making rule?

Continue an activity when marginal benefit ≥ marginal cost; choose the activity as long as the additional benefit is at least as large as the additional cost.

Why do economists focus on marginal analysis?

Because many economic decisions involve determining whether the additional benefit of an action is worth its additional cost.

What are incentives?

Factors that motivate people to behave in particular ways by changing the costs or benefits of choices.

What does it mean to think at the margin?

To compare the additional benefits with the additional costs of a decision.

How does opportunity cost affect decision-making?

Every choice requires giving up the next-best alternative, so the opportunity cost should be considered when evaluating a decision.

If the marginal benefit of studying for another hour is greater than the marginal cost, what should a rational decision-maker do?

Study for the additional hour.

How do economists use the scientific method?

They observe economic behavior, formulate hypotheses, collect and analyze data, test hypotheses, and develop or revise economic principles.

What is an economic theory?

A generalized explanation of how economic variables are related and how people or institutions behave.

Why do economists use models?

Models simplify reality so economists can focus on the most important relationships and make predictions.

What is ceteris paribus?

A Latin phrase meaning "other things being equal" or "all else held constant."

Example of ceteris paribus?

If economists examine how price affects quantity demanded, they may assume income, tastes, and prices of related goods remain constant.

What are the basic steps policymakers use?

Identify a problem → formulate goals → consider possible policies → evaluate the alternatives → implement a policy → monitor the results.

Why must policymakers consider trade-offs?

Because resources are scarce, so achieving one goal may require sacrificing another.

What is microeconomics?

The study of individual consumers, firms, and specific markets.

What is macroeconomics?

The study of the economy as a whole, including inflation, unemployment, economic growth, and national output.

What is positive economics?

Economic analysis that describes what is, what was, or what will be and can potentially be tested using evidence.

A government owns all resources and relies on a central planning board to make production decisions. What system is this?

The command system.

An economy relies on private property and decentralized markets where the government only protects property and enforces contracts. What system is this?

Laissez-faire capitalism.

How are economic systems primarily distinguished from one another?

By the degree of decentralized use of markets and prices versus centralized government control.

What is the primary role of government in an ideal laissez-faire capitalist economy?

To protect private property from theft and provide a legal environment for contract enforcement.

Which economic system relies on government ownership of resources and a central planning board?

The command system.

What countries are identified as utilizing a command system in the text?

North Korea, Cuba, and Myanmar.

How is the market system best characterized?

A mix of decentralized decision making with some government control, where private markets are dominant.

What are the core characteristics of the market system?

Private property, freedom of enterprise and choice, self-interest, competition, and markets and prices.

How do consumers determine what goods and services will be produced?

Through consumer sovereignty and 'dollar votes'.

How do businesses determine how goods and services will be produced?

By minimizing the cost per unit using the most efficient technology and resource prices.

What determines who will get the output in a market economy?

Consumers' ability and willingness to pay, which depends on their income.

What three factors drive changes in an economic system?

Changes in consumer tastes, technology, and resource prices.

What three mechanisms help an economic system promote progress?

Technological advance, creative destruction, and capital accumulation.

Who introduced the concept of the 'invisible hand' and in what work?

Adam Smith in his 1776 publication Wealth of Nations.

What three virtues of the market system are highlighted by the invisible hand?

Efficiency, incentives, and freedom.

Why did command systems in the Soviet Union and Eastern Europe ultimately fail?

Due to the coordination problem and the incentive problem.

What is the coordination problem in a command system?

The difficulty of setting correct output targets for all goods without market price signals.

What is the incentive problem in a command system?

The lack of adjustments or motivations for dealing with surpluses or shortages.

What are the two primary decision-making entities in the circular flow model?

Households and businesses.
