Quiz: Introduction to Economics and Finance — 13 questions

1. What is the central economic problem created by resources being limited relative to human wants?

A. Consumer sovereignty

B. Market equilibrium

C. Scarcity

D. Economic abundance

Answer: (C)

Explanation

Scarcity exists because available resources cannot satisfy all human wants. Economic abundance describes a situation in which resources are not constrained relative to wants, so it does not identify the central problem here.

2. Which set contains the main categories of economic resources, also called factors of production?

A. Savings, profits and wages, and interest

B. Labour, land and raw materials, and capital

C. Demand, supply and markets, and equilibrium

D. Income, prices and taxation, and consumption

Answer: (B)

Explanation

Economic resources consist of labour, land and raw materials, and capital. Demand and supply describe market relationships rather than categories of productive resources.

3. Why do economists examine both demand and supply in markets?

A. To measure whether resources are physically unlimited

B. To separate human inputs from financial assets

C. To classify natural inputs according to ownership

D. To understand how market quantities can be reconciled

Answer: (D)

Explanation

Economists study demand and supply to understand their interaction and the importance of reconciling them in markets. Classifying labour and natural inputs addresses factors of production, not the relationship between market forces.

4. Which issue is most clearly a macroeconomic concern?

A. A household's choice of groceries

B. The national unemployment rate

C. The pricing decision of one firm

D. The demand for a particular brand

Answer: (B)

Explanation

Unemployment is a macroeconomic issue because it concerns the performance of the economy as a whole. Household, firm, and individual-product decisions are typically microeconomic concerns.

5. What is the focus of supply-side macroeconomic policy?

A. Changing demand for one product

B. Improving aggregate supply

C. Increasing one household's consumption

D. Regulating a single firm's wages

Answer: (B)

Explanation

Supply-side policy is concerned with aggregate supply across the economy. Policies aimed at aggregate demand belong to the demand-side category, while the other choices concern individual markets or decision makers.

6. What does opportunity cost measure when a scarce resource is used to make a choice?

A. The market price charged by every supplier

B. The quantity of resources available before choosing

C. The total money held by the decision maker

D. The cost associated with the choice made

Answer: (D)

Explanation

Opportunity cost is the cost associated with choices made when resources are scarce. The amount of money held and the resources available describe conditions surrounding a choice, not its opportunity cost.

7. A firm should expand an activity when its marginal benefit exceeds its marginal cost because rational decision making calls for what response?

A. Stopping every activity with a positive cost

B. Keeping output fixed regardless of benefits

C. Doing more of the activity

D. Doing less of the activity

Answer: (C)

Explanation

Rational decision making requires doing more when marginal benefit is greater than marginal cost. Doing less is appropriate when marginal cost exceeds marginal benefit, so it does not fit this situation.

8. What does a production possibility curve show about an economy?

A. The amount of money created by the banking system

B. The production choices available under stated conditions

C. The income earned by each household in the economy

D. The prices charged for every product in a market

Answer: (B)

Explanation

A production possibility curve shows the production choices available to an economy and connects those choices with opportunity cost. Household income, product prices, and money creation are not what the curve represents.

9. What does increasing opportunity cost mean on a production possibility curve?

A. The economy produces more outputs without giving anything up

B. The economy operates below its possible production capacity

C. The output trade-off becomes larger as production changes

D. The set of available production choices remains unchanged

Answer: (C)

Explanation

Increasing opportunity cost means that the trade-off between outputs becomes larger as production changes. Operating below possible capacity describes production within the curve in macroeconomic analysis, not increasing opportunity cost itself.

10. What does the circular flow of income model describe?

A. Transactions between governments and banks through financial markets

B. Interactions between firms and households through goods and factor markets

C. Distribution of income among households within a single region

D. Competition among firms within a particular goods market

Answer: (B)

Explanation

The model represents how firms and households interact through both goods markets and factor markets. A particular market, by contrast, is narrower than the circular-flow model and does not capture the whole interaction between these two groups.

11. Which pairing correctly describes the real and money flows in goods markets?

A. Labour services flow as the real flow, while wages flow as the money flow

B. Goods and services flow as the real flow, while consumer expenditure flows as the money flow

C. Consumer expenditure flows as the real flow, while goods and services flow as the money flow

D. Wages flow as the real flow, while household labour services flow as the money flow

Answer: (B)

Explanation

In goods markets, firms provide goods and services as the real flow, while households provide consumer expenditure as the corresponding money flow. Labour services and wages belong to the factor-market flows instead.

12. A household supplies labour to a firm and receives income in return; which flows are represented in this factor-market exchange?

A. Goods and services as the real flow and consumer expenditure as the money flow

B. Consumer expenditure as the real flow and goods sales as the money flow

C. Wages as the real flow and labour services as the money flow

D. Labour services as the real flow and wages as the money flow

Answer: (D)

Explanation

Factor markets involve the real flow of labour and other factor services and the money flow of wages and other incomes. Goods and consumer expenditure describe the exchange taking place in goods markets.

13. How does macroeconomic analysis of the circular flow differ from microeconomic analysis?

A. Macroeconomics examines household choices, whereas microeconomics measures the size of total national flows

B. Macroeconomics examines the size of total flows, whereas microeconomics examines individual markets and choices

C. Macroeconomics focuses on firms and households together, whereas microeconomics excludes their market interactions

D. Macroeconomics studies factor services, whereas microeconomics studies consumer expenditure in goods markets

Answer: (B)

Explanation

Macroeconomic analysis considers the overall size of flows in the economy, while microeconomic analysis focuses on individual markets and the choices made within them. Microeconomics does not exclude firms or households; it examines their decisions in particular markets.
