Study Notes

Economics Definition

Economics is a social science that studies how individuals, businesses, and nations make choices about allocating scarce resources to satisfy unlimited wants.

Economic Theory

Economics uses the scientific method to create theories. This involves:
- Observation: Studying real-world events.
- Hypothesis Development: Creating testable explanations.
- Data Collection: Gathering evidence.
- Hypothesis Acceptance/Rejection: Evaluating hypotheses using data.
Accepted hypotheses become theories, and repeated testing leads to established economic principles or laws.

Economic Models

Economic models simplify reality, combining multiple theories into frameworks.
They help understand and analyze complex economic situations, using simplified representations.

Scarcity and Opportunity Cost

Resources are scarce and have alternative uses.
Choosing one use means trading off other possibilities, which leads to an opportunity cost.

Purposeful Behavior

Individuals make decisions with desired outcomes in mind.
These choices are generally considered rational, aiming for the best possible result.
Factors like personal situations, preferences, and information influence choices.
Differences in choices do not automatically mean errors or irrationality.

Marginal Analysis

Decisions involve weighing the marginal benefits and costs of a small change.

Microeconomics vs. Macroeconomics

Microeconomics studies individual economic units and markets (individuals, firms, specific industries).
Macroeconomics examines the entire economy, looking at broad measures like national output, inflation, and unemployment.

Theoretical vs. Policy Economics

Theoretical economics analyzes objective reality and observable data.
Policy economics incorporates values and judgments to create recommendations about what should be.

Logical Positivism

Logical positivism emphasizes empirical verification as the basis for knowledge.
It rejects concepts without empirical evidence (e.g., values, beliefs) as valid knowledge.
Focuses on verifiable, measurable facts.

Value Judgments in Economics

Economists strive to avoid subjective value judgments in their analysis. However, interpreting data and creating policies necessitates value judgments.
Differing values lead to varying perspectives on economic performance (e.g., differing views on unemployment rates).

Positive vs. Normative Economics

Positive economics describes facts, avoiding value judgments (e.g., "the unemployment rate is 5%").
Normative economics prescribes what "should be" and offers policy recommendations (e.g., "the unemployment rate is too high and needs reduction").

Scarcity and Resources

Scarcity is a fundamental economic issue facing all individuals, societies, governments, and organizations.
Key resources for societies: land, labor, capital, and entrepreneurial ability.

Resources Explained

Land: Natural resources (minerals, oil, gas, water, wind, solar).
Labor: Human resources, skilled and unskilled.
Capital: Manufactured resources used in production (tools, equipment, factories, transportation).
Entrepreneurial Ability: The ability to combine land, labor, and capital effectively, taking risks in business decisions.

Production Possibilities Model

Production Possibilities Curve (PPC) illustrates the maximum combinations of two goods an economy can produce, given resources and technology.
PPC Assumptions:
- Full employment of resources.
- Fixed resources and technology.
PPC Concepts:
- Unemployment: Points inside the curve.
- Inefficiency: Points inside the curve.
- Full Employment: Points on the curve.
- Economic Growth: Shifting the curve outwards.
- Opportunity Cost: The trade-offs when increasing production of one good.
Trade-offs demonstrate that increasing production of one good requires decreasing the production of another.

Example of the Production Possibilities Model

Example uses pizza (consumer good) and industrial robots (capital good) to illustrate the PPC.
Different points on the curve represent various combinations of goods produced.
Points illustrate choices between consumer and capital goods production.
The PPC's downward slope illustrates trade-offs: Shifting resources from one product to another involves an opportunity cost.
The initial unit of a good means sacrificing a specific amount (opportunity cost) of another good

Opportunity Cost

Opportunity cost represents the cost of choosing one option by forgoing another.

It is the value of the next best alternative.
Moving from one point to another on the PPC demonstrates the opportunity cost.

Law of Increasing Opportunity Cost

The PPC's concave shape shows increasing marginal opportunity costs as production of a good increases.
This happens because resources are not equally suited for all activities.
Initially, the most efficient resources are used, leading to a smaller trade-off.
As production increases, less efficient resources are used, resulting in a larger opportunity cost.

Unemployment

Unemployment lies inside the PPC, indicating unused resources and potential output below the economy's capacity.
Consequences: Lost output, reduced income, decreased business revenue.

Economic Growth

Economic growth is an outward shift of the PPC, due to increased resources and technology.
This allows for greater production of all goods and services.
