Economics: An Overview

What is Economics?

Economics, a branch of social science, studies the production, distribution, and consumption of goods and services. It examines how societies organize and manage economic activity.

  • Definition: Economics explores how society decides what to produce, how to produce it, and for whom, given limited resources.
  • Resource Management: It analyzes how scarce resources are managed to produce and distribute goods and services among society’s members.
  • Resource Allocation: Economics studies the optimal allocation of a company’s scarce resources to achieve a set of objectives.

Microeconomics vs. Macroeconomics

Microeconomics

Microeconomics examines the economic behavior of individual elements within an economy. This includes factors like:

  • The price and demand of a commodity or product.
  • The supply of a particular good and its market.
  • Consumer tastes and preferences.

Macroeconomics

Macroeconomics analyzes the economy as a whole, focusing on aspects such as:

  • A country’s total output.
  • Money supply.
  • Levels of imports and exports.
  • Unemployment and inflation.
  • National budget revenues and expenditures.

Hierarchy of Needs

  1. Physiological Needs: Food, clothing, shelter.
  2. Safety Needs: Security and protection from physical and emotional harm.
  3. Social Needs: Affection, belonging, acceptance, and friendship.
  4. Esteem Needs: Self-respect, self-esteem, autonomy, achievement, status, recognition, and attention.
  5. Self-Actualization Needs: Growth, realizing one’s potential, self-satisfaction, and the drive to become the best version of oneself.

Economic Agents

The key players in an economic system are:

  • Families: Make decisions about consumption and savings, choosing goods and services to meet their needs.
  • Government: Oversees the system’s operation and directly participates in the economy through activities like collecting taxes, undertaking public works, managing healthcare, ensuring national security, and providing education.
  • External Sector: Includes entities outside the country, such as businesses, consumers, and governments of other nations, who make decisions about spending, buying and selling goods and services (imports and exports), and engaging in lending and borrowing.

Classification of Goods

Goods are objects or activities that are valued and produced to satisfy needs.

1. Economic Viewpoint

  • Free Goods: Relatively abundant, have no owner or price, and require no production factors.
  • Economic Goods: Relatively scarce, have owners and prices, and require production factors.

2. Depending on Use

  • Capital Goods: Used in the production of other goods (also called intermediate goods or resources).
  • Consumer Goods: Intended to satisfy an immediate need.

Durability

  • Durable Goods: Satisfy a need over a long period.
  • Non-Durable Goods: Satisfy a need once or disappear after use.

3. According to Material

  • Tangible Goods: Physical objects with mass.
  • Intangible Goods: Services, lacking physical form.

5. Relationship Between Goods

  • Substitute Goods: Satisfy the same need but with different technologies.
  • Complementary Goods: Consumed together to satisfy the same need.

6. From the Income Perspective

  • Normal Goods: Consumption remains relatively constant regardless of income level.
  • Inferior Goods: Consumption increases as disposable income decreases.
  • Superior Goods: Consumption increases as disposable income increases.

Economic Efficiency

  • Efficiency: Finding the best and maximum use of resources for a specific purpose.
  • Economic Efficiency: Achieving a given output of goods and services at the lowest possible cost while preserving resources.
  • Production Efficiency: Achieving a given output using the least amount of inputs.

Opportunity Cost

Choosing one alternative means rejecting others, incurring a cost. This cost represents what we forgo because our resources are limited. The opportunity cost of a good or service is the amount of other goods and services we must give up to obtain it.

Law of Diminishing Returns

Occurs when adding successive amounts of one factor to the production process (while holding other factors constant) yields decreasing amounts of output.

Production Possibilities Frontier (PPF)

  • The Basic Economic Problem: Limited resources necessitate choices, which can be illustrated graphically.
  • The PPF: Shows the maximum quantity of a good or service an economy can produce given its resources and technology, considering the amounts of other goods and services also produced.
