Study Notes

What is Economics?

Economics is the study of efficient allocation of scarce resources to meet unlimited needs and wants.
It examines how individuals, businesses, governments, and societies satisfy their needs with limited resources.

Microeconomics vs. Macroeconomics

Microeconomics studies individual economic agents like households and firms and their decision-making processes regarding resource use.
Macroeconomics looks at the economy as a whole, focusing on aggregate phenomena such as GDP, inflation, unemployment, and national income.

Importance of Microeconomics

Analyzes how resources are allocated at the individual and firm levels.
Explains price determination through supply and demand interactions.
Identifies market efficiencies and potential failures.
Aids policymakers in designing tax, regulation, and welfare policies.
Provides business insights for decision-making on production and pricing.
Examines income distribution and addresses issues of inequality and poverty.

Basic Economic Concepts

Economic Problem: The challenge of satisfying unlimited wants with limited resources.
Needs: Essential requirements for survival and well-being (food, shelter, healthcare).
Wants: Desires shaped by culture and individual preferences that extend beyond basic needs.
Scarcity: The condition where resources are limited compared to the demand for them.
Choice: The decision-making process among alternatives due to scarcity.
Productivity: Efficiency of resource use in producing goods and services.
Factors of Production: Inputs such as land, labor, capital, and entrepreneurship used in production.
Opportunity Cost: The value of the next best alternative foregone when making a decision.
Trade-off: The sacrifice of one option for another, closely linked to opportunity cost.

Principles of Microeconomics

Decision-Making: Individuals face trade-offs; costs involve what is sacrificed; rational choices are made at the margin; incentives influence behaviors.
Interaction: Trade benefits all parties; markets effectively organize economic activities; government can improve market outcomes.
Overall Economy: National well-being hinges on productive capacity; inflation occurs when too much money is printed; society experiences trade-offs between inflation and unemployment.

Economic Models

Circular Flow Diagram: Illustrates the movement of goods and services and money between households and firms, highlighting the interactions within factor and product markets.
Production Possibilities Frontier (PPF): Depicts maximum combinations of outputs that can be produced with available resources and technology; shifts can occur with changes in technology or resource availability.

Positive vs. Normative Economics

Positive Economics: Describes and explains economic phenomena without value judgments; relies on data and empirical evidence (e.g., "Increasing minimum wage may decrease low-skilled employment").
Normative Economics: Involves value judgments and opinions about economic actions (e.g., "Government should increase education spending for societal benefits"); focuses on what should be done for improvements.
