Study Notes

Chapter 1: Limits, Alternatives, and Choices

Economics is a social science focused on optimal choices in a world of scarcity.
Economic wants typically exceed society's productive capacity.

The Economic Perspective

This perspective envisions individuals and institutions making rational decisions based on self-interest.
Key considerations include:
- Scarcity and choice
- Opportunity cost
- Purposeful behavior to increase utility
- Marginal analysis (comparing marginal benefits and costs)

Scarcity and Choice

Resources are scarce.
Choices must be made.
Opportunity cost exists—there is no free lunch.

Purposeful Behavior

Individuals act with rational self-interest.
This includes seeking utility maximization.
Businesses seek profit maximization.
The desired outcome is always in mind.

Marginal Analysis

Comparing marginal benefits and marginal costs is a common tool for decision-making.
Marginal means "extra" or "additional."

Theories, Principles, and Models

The scientific method is used to develop theories, principles, and laws.
- Observe
- Formulate a hypothesis
- Test the hypothesis
- Accept, reject, or modify the hypothesis
- Continue to test if needed

Economic Principles

Other-things-equal assumption (ceteris paribus): Factors not being considered remain constant.
Graphical expression often used to represent economic principles.

Microeconomics and Macroeconomics

Microeconomics studies individual consumers, firms, and markets.
Macroeconomics studies the entire economy or large segments.

Positive and Normative Economics

Positive economics describes factual statements.
Normative economics involve value judgments.

The Economizing Problem

Individuals face a limited income with unlimited wants.
The budget line illustrates attainable and unattainable combinations of goods.
Trade-offs and opportunity costs are central to this problem.
Choices and income changes affect individual and societal economizing.

A Consumer's Budget Line

Shows combinations of goods attainable with a given income.
The slope shows the opportunity cost between different goods.

Global Perspective

Average income per person varies significantly across nations.
Factors like cost of living and exchange rates need adjustments for meaningful comparisons.

Society's Economizing Problem

Four key resources are essential for societal production:
- Land (natural resources)
- Labor (physical and mental work)
- Capital (man-made objects and intangible ideas used in production)
- Entrepreneurial ability (distinct from labor—organizing and innovating)

Functions of Entrepreneurs

Employ factors of production
Assume initiative
Make strategic decisions
Innovate
Take risks

Production Possibilities Model

An economic model representing different combinations of two goods an economy can produce, given resource constraints and technology.
Assumptions usually include full employment, fixed resources, fixed technology, and two goods.
One good is typically consumer goods, another is typically capital goods.

The Production Possibilities Curve

Shows different output combinations of two goods.
Points on the curve represent maximum output levels.
Points outside the curve are unattainable.
Points inside the curve represent underutilization of resources.

Increasing Opportunity Costs

The cost of producing more of one good typically increases as the economy shifts production toward it.
The production possibilities curve is typically concave to illustrate this.
Economic rationale: Resources aren't perfectly adaptable to different production tasks.

Optimal Output

Optimal output occurs where marginal benefit (MB) equals marginal cost (MC).

Unemployment, Growth, and the Future

Economic growth shifts the production possibilities curve outwards.
Unemployment implies the economy is operating inside the curve.

Present Choices, Future Possibilities

Present choices affect future possibilities, with implications for future production potential.

Global Perspective (Gross Fixed Capital Formation)

Measures how much a country invests in capital goods as a proportion of national income.

International Trade

Specialization in the production of particular goods leads to increased production possibilities through international trade.

Pitfalls to Sound Economic Reasoning

Avoid biases, loaded terminology, fallacies of composition, post hoc fallacies, and confusing correlation with causation.
