Study Notes

The Scientific Method in Economics

Economists utilize the scientific method to analyze real-world phenomena.
They develop theories and test them with data.
Assumptions simplify complex situations to better understand cause and effect.

The Role of Assumptions

Economists make assumptions to simplify models and make them easier to comprehend.
An example is the simplified model of international trade with only two countries.

Economic Models

Economic models are simplified representations used to analyze economic situations.
The Circular-Flow Diagram and Production Possibilities Frontier are two key models.

Circular-Flow Diagram

Illustrates the flow of goods, services, and resources between households and firms.
Shows the interactions in two main markets: the market for goods and services, and the market for factors of production.

Production Possibilities Frontier (PPF)

Shows the trade-offs between producing two goods.
Demonstrates opportunity costs, efficiency, and economic growth.

Microeconomics vs Macroeconomics

Microeconomics focuses on individual markets and decision-makers like households and firms.
Macroeconomics focuses on broader economic factors such as inflation, unemployment, and national income.

Positive vs Normative Analysis

Positive statements are objective and based on facts.
Normative statements are subjective and value-based.
Example:
- Positive: Increasing the minimum wage will reduce employment.
- Normative: The government should raise the minimum wage.

Economists as Policy Advisers

Economists provide advice to policymakers based on positive analysis.
They offer recommendations on issues like minimum wage laws, taxation, and healthcare reforms.

Why Economists Disagree

Differences arise from varying scientific judgments, models, and values.
For example, economists may disagree about the balance between fairness and efficiency.
