Study Notes

Economic Systems and Agents

Economists analyze economic systems and interactions among economic agents, including individuals, businesses, organizations, and governments.
The purpose of economics is to explore the optimal use of scarce resources to achieve objectives.

Classification of Economics

Divided into microeconomics and macroeconomics.
Microeconomics studies individual and household decision-making to address economic problems and resource allocation.
Macroeconomics examines systems as a whole, aiming to achieve large-scale objectives like maximizing employment and maintaining price stability.

Nature of Economics

Economists apply scientific methods to observe and explain behaviors of economic agents.
Adam Smith emphasized the importance of objectivity in economic analysis.
The scientific approach involves forming hypotheses, collecting evidence, testing hypotheses, and developing theories.

Variables in Economics

A variable is an element that can change and affect outcomes.
Independent variables are causes, while dependent variables are the effects.
Example: In an experiment, heat can be the independent variable affecting the chemical reaction (dependent variable).

Economics vs. Pure Science

Although economics uses scientific methods, it is not a pure science; experiments involving humans are often unethical or impractical.
Economists build models and use reasoning rather than controlled experiments.

Ceteris Paribus Rule

The ceteris paribus rule assumes all other factors remain constant when analyzing economic variables.
This rule is crucial for testing hypotheses and understanding relationships between variables.

Positive and Normative Economics

Positive statements can be tested and verified, such as "house prices rose by 6% in London."
Normative statements are value judgments and cannot be tested, for example, "the rise in house prices is unfair to the poorest."
Economic advancement relies on generating and testing positive statements and hypotheses.

Summarized Comparisons

Positive statements focus on measurable outcomes while normative statements reflect personal beliefs.
Distinction: Positive statements are based on facts and data, normative statements are subjective value judgments.
