Study Notes
Economics Fundamentals
- Economics is the study of choices people and societies make to attain their unlimited wants, given their scarce resources.
- Markets are groups of buyers and sellers of a good or service and the institution or arrangement by which they come together to trade.
Three Key Economic Ideas
- People are rational.
- People respond to economic incentives.
- Optimal decisions are made at the margin.
- Marginal analysis compares marginal benefits and marginal costs.
Scarcity and Trade-offs
- Scarcity exists when unlimited wants exceed the limited resources available to fulfill those wants.
- Resources are the inputs used to produce goods and services, including natural resources, labor, capital, and entrepreneurial ability.
- Trade-offs result from scarcity and involve producing more of one good or service while producing less of another.
Opportunity Cost
- Opportunity cost is the highest-valued alternative that must be given up to engage in an activity.
Efficiency
- Productive efficiency occurs when a good or service is produced using the least amount of resources.
- Allocative efficiency happens when production reflects consumer preferences; in particular, every good or service is produced up to the point where the last unit provides a marginal benefit to consumers equal to the marginal cost of producing it.
- Dynamic efficiency occurs when new technology and innovation are adopted over time.
Economic Models
- Economic models are simplified versions of reality used to analyze real-world economic situations.
- Economic variables are measurable aspects related to resources that can have different values, such as wages, prices, and liters of petrol.
- Economic models make behavioral assumptions about the motives of consumers and firms.
- Economists develop models by following these steps:
- Decide on the assumptions to be used.
- Formulate a testable hypothesis.
- Use economic data to test the hypothesis.
- Revise the model if it fails to explain the economic data.
- Retain the revised model to help answer similar economic questions in the future.
Production Possibility Frontiers (PPF)
- PPF is a curve showing the maximum attainable combinations of two products that may be produced with available resources.
- The bowed-out shape of the PPF illustrates the concept of increasing marginal opportunity costs.
Comparative Advantage
- Comparative advantage is the ability of an individual, firm, or country to produce a good or service at a lower opportunity cost than others.
- Countries specialize in producing goods with comparative advantage and trade with other countries, leading to overall gains from trade.
Market System
- A market system is an economic system in which individuals and firms make decisions about resource allocation through voluntary exchange in markets.
Property Rights
- Property rights are the legal rights to use, control, and transfer resources.
- Well-defined property rights are essential for a well-functioning market system as they:
- Encourage investment and innovation
- Promote efficiency and productivity
- Reduce disputes and conflicts over resources
