Q1 What is the difference between Microeconomics and Macroeconomics?

The key differences lie in the scope of study and the variables involved:

Basis Microeconomics Macroeconomics
Scope Studies individual economic units (e.g., a consumer, a firm). Studies the economy as a whole (e.g., National Income, Aggregate Demand).
Central Problem Determination of price and output in individual markets. Determination of income and employment level in the economy.
Main Tools Demand and Supply. Aggregate Demand and Aggregate Supply.
Objective To maximize individual utility or profit. To maximize social welfare and economic growth.
Q2 What are the important features of a Capitalist Economy?

A capitalist economy is characterized by the following features:

  • Private Ownership: The factors of production (land, labor, capital) are owned and controlled by private individuals, not the government.
  • Profit Motive: The primary driving force behind economic activities is the generation of profit.
  • Market Mechanism: Prices are determined by the forces of demand and supply (Price Mechanism) without government intervention.
  • Freedom of Enterprise: Individuals are free to make their own economic decisions regarding what to produce, how to produce, and for whom to produce.
  • Competition: There is free competition among firms to sell goods and among consumers to buy goods.
Q3 Describe the four major sectors in an economy according to the macroeconomic point of view.

In macroeconomics, the economy is divided into four key sectors:

  1. Household Sector: Includes consumers of goods and services. They are also the owners of factors of production (supplying land, labor, capital, and entrepreneurship).
  2. Firms (Production Sector): Includes all economic units that carry out production. They hire factors of production from households to produce goods and services.
  3. Government Sector: Includes the state or government which acts as a welfare agency (maintaining law and order, defense) and a producer (public sector enterprises). It also collects taxes and pays subsidies.
  4. External Sector (Rest of the World): Deals with the export and import of goods and services and the flow of capital between the domestic economy and other countries.
Q4 Describe the Great Depression of 1929.

The Great Depression was a severe worldwide economic depression that took place predominantly during the 1930s, beginning in the United States.

  • The Event: It started with the stock market crash in 1929 and led to a catastrophic decline in production and employment.
  • Key Characteristics:
    • Fall in Aggregate Demand: Consumers stopped spending, leading to a pile-up of unsold inventories.
    • Unemployment: Unemployment rates soared (e.g., in the USA, it rose from 3% to 25%).
    • Deflation: Prices of goods and services fell drastically.
  • Impact on Economics: It shattered the classical belief that “supply creates its own demand” and led to the emergence of Keynesian Economics (John Maynard Keynes), which advocated for government intervention to boost aggregate demand.
