Definition of Economics

• Economics studies how societies allocate scarce resources to meet unlimited wants.

Major Branches of Economics

• Microeconomics

  • Analyzes supply and demand dynamics, price setting, and consumer purchasing habits.

• Macroeconomics

  • Examines the economy in its entirety, considering aggregate measures.
  • Key indicators include Gross Domestic Product (GDP), unemployment rates, inflation, and national income.

Key Concepts

• Scarcity

  • Represents the limited availability of resources in comparison to infinite consumer desires.

• Opportunity Cost

  • Refers to the value of the next best alternative that is lost when a decision is made.

• Supply and Demand

  • Supply indicates the total quantity of goods or services available for purchase.
  • Demand expresses consumers' willingness and ability to buy those goods or services.

• Market Equilibrium

  • The condition where supply equals demand, which helps in determining the market price.

• Economic Systems

  • Traditional: Relies on customs and historical practices.
  • Command: Central authority dictates resource allocations and production.
  • Market: Decisions are influenced by supply and demand dynamics.
  • Mixed: Combines elements of both market and command systems.

Economic Indicators

• Gross Domestic Product (GDP)

  • Measures the total monetary value of all finished goods and services produced within a country over a specified period.

• Unemployment Rate

  • Indicates the percentage of the labor force that is jobless yet actively seeking employment.

• Inflation Rate

  • Represents the pace at which the overall level of prices for goods and services is rising, eroding purchasing power.

Types of Economic Policies

• Monetary Policy

  • Consists of measures implemented by central banks to control money supply and interest rates.

• Fiscal Policy

  • Involves government spending decisions and tax strategies aimed at influencing economic performance.

• Classical Economics

Current Issues in Economics

• Globalization influences interwoven trade policies and international market dynamics.
• Income inequality raises concerns regarding wealth distribution and economic fairness.
• Environmental sustainability impacts economic practices and resource management.
• Technology's role in disrupting labor markets and enhancing productivity is a growing focus.
