Quiz: What is Economics?

Test your understanding of the fundamental concepts of economics with these review questions.

1. What is the fundamental economic problem that forces people to make choices?

  1. Scarcity
  2. Inflation
  3. Unemployment
  4. Government regulation
Show Answer

The correct answer is A. Scarcity is the basic economic problem: there are not enough resources to satisfy all human wants. This applies to everyone, regardless of wealth. Even billionaires face scarcity of time. Because resources are limited and wants are unlimited, people must make choices about how to use what they have.

Concept Tested: Scarcity

2. You choose to attend a concert instead of working a shift that would pay $60. The ticket costs $30. What is the opportunity cost of attending the concert?

  1. $30
  2. $60
  3. $90
  4. $0, because you enjoyed the concert
Show Answer

The correct answer is C. Opportunity cost includes both the direct cost ($30 for the ticket) and the value of the best alternative you gave up ($60 in wages). So the total opportunity cost is $30 + $60 = $90. Opportunity cost captures the true price of every decision, not just the money spent.

3. Which statement is an example of normative economics?

  1. The unemployment rate is currently 4.1%
  2. When prices rise, people tend to buy less
  3. The government should raise the minimum wage
  4. Raising taxes by 5% would increase revenue by $200 billion
Show Answer

The correct answer is C. Normative economics describes "what ought to be" and involves value judgments. The word "should" is a giveaway. Options A, B, and D are positive statements that can be tested and verified with data. Distinguishing positive from normative claims is essential for spotting opinions disguised as facts.

4. In a command economy, who answers the three fundamental economic questions of what, how, and for whom to produce?

  1. Individual consumers and businesses
  2. The stock market
  3. International trade organizations
  4. Government central planners
Show Answer

The correct answer is D. In a command economy, the government answers all three fundamental economic questions through central planning agencies. Government planners decide what to produce, how to produce it, and who receives the output. Real-world examples include the former Soviet Union, North Korea, and Cuba.

Concept Tested: Command Economy

5. What does marginal analysis help a decision-maker determine?

  1. Whether one more unit is worth the additional cost
  2. The total cost of all units produced
  3. The historical average of past decisions
  4. The maximum possible output of a factory
Show Answer

The correct answer is A. Marginal analysis examines decisions in terms of "one more unit" rather than all-or-nothing. It compares the marginal benefit (additional satisfaction or revenue) to the marginal cost (additional expense) of one more unit. Smart decisions happen when marginal benefit equals marginal cost.

6. Which of the following is an example of capital as a factor of production?

  1. A barrel of crude oil
  2. A $10,000 savings account
  3. A company CEO's leadership
  4. A factory assembly robot
Show Answer

The correct answer is D. In economics, capital refers to human-made resources used to produce other goods, such as machines, factories, and equipment. A factory assembly robot is physical capital. A savings account is financial capital (a different concept). Crude oil is land (natural resources), and a CEO's leadership is entrepreneurship.

7. A point located inside the Production Possibilities Frontier indicates that the economy is operating with what condition?

  1. Maximum efficiency
  2. Inefficiency or unused resources
  3. Impossible output levels
  4. Allocative efficiency
Show Answer

The correct answer is B. Points inside the PPF represent inefficiency, meaning the economy is not using all its resources or is using them poorly. Points on the frontier represent efficient production, while points outside the frontier are unattainable with current resources. An economy inside its PPF could produce more without giving anything up.

8. A daycare started fining parents for late pickups, but late arrivals actually increased. This is best explained by which economic concept?

  1. Diminishing marginal benefit
  2. Comparative advantage
  3. Unintended consequences of incentives
  4. The law of supply
Show Answer

The correct answer is C. This classic example demonstrates how incentives can backfire. Before the fine, parents felt guilty about being late (a social incentive). After the fine was introduced, parents viewed it as simply paying for extra childcare, which eliminated the guilt. The financial incentive accidentally replaced a more powerful social incentive, leading to unintended consequences.

Concept Tested: Incentives

9. What distinguishes microeconomics from macroeconomics?

  1. Microeconomics studies money; macroeconomics studies trade
  2. Microeconomics focuses on individual markets; macroeconomics studies the economy as a whole
  3. Microeconomics is theoretical; macroeconomics is practical
  4. Microeconomics studies businesses; macroeconomics studies consumers
Show Answer

The correct answer is B. Microeconomics zooms in on individual decision-makers and specific markets, such as how consumers choose what to buy or how businesses set prices. Macroeconomics looks at the entire economy, studying questions like what causes recessions, inflation, and unemployment. Think of micro as studying individual trees while macro examines the whole forest.

10. Almost every real-world economy today is best described as which type of economic system?

  1. Pure market economy
  2. Command economy
  3. Traditional economy
  4. Mixed economy
Show Answer

The correct answer is D. A mixed economy combines elements of both market and command systems. Markets handle most decisions, but government provides certain goods (roads, defense), regulates activities (environmental rules, safety standards), and redistributes some income (taxes, welfare). The United States, Sweden, Japan, and virtually all modern nations are mixed economies with different balances between market and government roles.
