demand

Answer 3

• The quantity of a good or service that consumers are willing and able to buy at various prices.
• As the price of a good decreases, consumers are generally willing to buy more.

Question 4

Explain:

choice

Context of economics

Answer 4

• Because of scarcity, individuals and societies must make choices about how to allocate resources.
• Every choice involves trade-offs, meaning that to gain something, something else must be given up.

Answer 39

The value of the next best alternative foregone when making a decision. ## Footnote Opportunity cost is a fundamental concept in economics that highlights the trade-offs involved in any decision-making process. It emphasizes that choosing one option means giving up others.

Question 40

# Fill in the blank: Scarcity refers to the limited nature of society's \_\_\_\_\_\_.

Answer 40

resources ## Footnote Scarcity is a core concept in economics, as it forces individuals and societies to make choices about how to allocate limited resources to satisfy unlimited wants.

Question 41

List the **factors** that can cause a shift in the demand curve.

Answer 41

* Changes in consumer preferences * Changes in consumer income * Prices of related goods (substitutes and complements) * Expectations of future prices * Number of buyers ## Footnote A shift in the demand curve indicates a change in demand at every price point, as opposed to a movement along the curve, which is caused by a change in the price of the good itself.

Question 42

How does scarcity **influence** economic decision-making?

Answer 42

Scarcity forces individuals and societies to prioritize needs and allocate resources efficiently. ## Footnote Due to scarcity, choices must be made about what to produce, how to produce, and for whom to produce, leading to trade-offs and opportunity costs.

Question 43

What happens to the supply of a good when its price **increases**, assuming all other factors remain constant?

Answer 43

The supply of the good increases. ## Footnote According to the law of supply, there is a direct relationship between the price of a good and the quantity supplied. As prices rise, producers are more willing to supply more of the good to the market.

Question 44

In a supply and demand scenario, what is the **equilibrium price**?

Answer 44

The price at which the quantity supplied equals the quantity demanded. ## Footnote At equilibrium, there is no tendency for the price to change, as the market is in a state of balance with no excess supply or demand.

Question 45

What are the **key characteristics** of a perfectly competitive market?

Answer 45

* Many buyers and sellers * Homogeneous products * Free entry and exit * Perfect information ## Footnote In a perfectly competitive market, no individual buyer or seller can influence the market price, leading to a situation where firms are price takers.

Question 46

# Fill in the blank: A \_\_\_\_\_\_ is a market structure where a single firm controls the entire market supply of a product or service.

Answer 46

monopoly ## Footnote Monopolies can arise due to factors like control of a key resource, government regulation, or economies of scale that prevent new competitors from entering the market.

Question 47

What are the main features of a **monopoly**?

Answer 47

* Single seller * Unique product with no close substitutes * High barriers to entry * Price maker ## Footnote Monopolies can lead to higher prices and reduced output compared to more competitive market structures, potentially resulting in consumer harm.

Question 48

How does an oligopoly **differ** from a monopoly?

Answer 48

An oligopoly consists of a few large firms dominating the market, whereas a monopoly has only one firm. ## Footnote Oligopolies often engage in strategic behavior, such as collusion or price leadership, to maintain market power.

Question 49

List the characteristics of an **oligopoly**.

Answer 49

* Few dominant firms * Interdependent decision-making * Barriers to entry * Potential for collusion ## Footnote Oligopolistic markets can lead to outcomes similar to monopolies, but competition among the few firms can also drive innovation and efficiency.

Question 50

# Fill in the blanks: In a perfectly competitive market, firms are considered \_\_\_\_\_\_ \_\_\_\_\_\_.

price takers ## Footnote Because no single firm can influence the market price, they must accept the prevailing market price determined by overall supply and demand.

Question 51

What is the **primary reason** for high barriers to entry in a monopoly?

Answer 51

Control of a key resource, government regulation, or economies of scale. ## Footnote These barriers prevent new firms from entering the market, allowing the monopolist to maintain control over prices and output.

Question 52

What is a **trade deficit**?

Answer 55

A situation where a country's imports exceed its exports. ## Footnote A trade deficit can indicate that a country is consuming more than it is producing, which may lead to borrowing from foreign lenders to finance the excess imports.

Question 56

How does specialization **relate** to international trade?

Answer 56

Countries focus on producing goods where they have a comparative advantage, leading to more efficient production and trade. ## Footnote Specialization allows countries to produce a surplus of certain goods, which can then be traded for other goods that are more costly to produce domestically.

Question 57

# Fill in the blank: A \_\_\_\_\_\_ is a tax imposed on imported goods to protect domestic industries.

Answer 57

tariff ## Footnote Tariffs can make imported goods more expensive, encouraging consumers to buy domestically produced goods, but they can also lead to trade wars and increased prices for consumers.

Question 58

What role do **exchange rates** play in international trade?

Answer 58

Exchange rates determine the value of one currency in relation to another, affecting the cost of imports and exports. ## Footnote Fluctuations in exchange rates can impact trade balances, as a stronger currency makes exports more expensive and imports cheaper, while a weaker currency has the opposite effect.
