Introduction: What is Economics?
Economics is the study of how people, businesses, and governments use limited resources to meet unlimited wants. It helps us understand how goods and services are produced, distributed, and consumed.
Example: A student with only ₹50 has to decide whether to buy a notebook, a pen, or save it for lunch. This decision-making is economics in daily life.
Types of Economics
a) Microeconomics
Microeconomics deals with individual units of the economy such as households, firms, or industries. It studies supply, demand, prices, and consumer behavior.
Example: If the price of onions rises in Delhi, how will customers react? Some may reduce buying, and sellers may increase supply. This is microeconomics.
b) Macroeconomics
Macroeconomics looks at the economy as a whole. It studies national income, GDP, inflation, employment, poverty, and economic growth.
Example: When
RBI increases the repo
rate, loans become costlier for all citizens, reducing overall
demand in the economy.
