In the context of microeconomics, the concept of 'scarcity' refers to:
- A situation where demand always exceeds supply.
- The limited availability of resources relative to unlimited human wants.
- A state of perfect competition in all markets.
- The inability of firms to increase production.
Show answer
Answer: B. The limited availability of resources relative to unlimited human wants.
Scarcity is a fundamental concept in economics. It highlights the basic economic problem that arises because society's desires for goods and services are virtually unlimited, while the resources available to satisfy these desires are limited. This forces individuals and societies to make choices about how to allocate these scarce resources.
Which of the following is NOT a factor of production?
- Land
- Labor
- Capital
- Money
Show answer
Answer: D. Money
The traditional factors of production are Land (natural resources), Labor (human effort), and Capital (man-made aids to production). Entrepreneurship is often considered the fourth factor. Money is a medium of exchange and a store of value, but it is not directly involved in the production process itself; rather, it facilitates the acquisition of factors of production.
Marginal analysis involves comparing:
- Total costs and total benefits.
- Average costs and average benefits.
- Additional costs and additional benefits.
- Fixed costs and variable costs.
Show answer
Answer: C. Additional costs and additional benefits.
Marginal analysis is a decision-making tool that involves examining the additional benefits of an activity compared to the additional costs incurred. Rational decision-makers choose to do something if the marginal benefit outweighs the marginal cost.
Which of the following is an example of 'labor' as a factor of production?
- A farmer's tractor.
- A hydroelectric dam.
- The wages paid to factory workers.
- The skills and effort of a construction worker.
Show answer
Answer: D. The skills and effort of a construction worker.
Labor refers to the human effort, both mental and physical, that is used in the production of goods and services. The farmer's tractor is capital, the dam is infrastructure (capital), and wages are the payment for labor, not labor itself.
The bowed-out shape of the production possibilities frontier is a visual representation of:
- Increasing returns to scale.
- Diminishing marginal utility.
- The law of increasing opportunity cost.
- The law of supply and demand.
Show answer
Answer: C. The law of increasing opportunity cost.
As more of one good is produced, resources that are better suited for the other good must be diverted, leading to a progressively higher cost in terms of the forgone production of the other good. This is visually depicted by the concave (bowed-out) shape of the PPF.
