Scarcity, choice and trade-offs. Every economic question starts with the fact that wants exceed what is available.
Because resources are limited, every choice has an opportunity cost — the next best thing given up. Prices in a market emerge from supply and demand: more buyers than goods pushes prices up, which both rations the goods and signals producers to make more. Markets are efficient at this and bad at some other things, which is why governments provide public goods such as roads, defence and basic education, and regulate where market outcomes are unacceptable.
GDP measures the value of what a country produces, and is the most quoted and most misread economic number. It says nothing about distribution, nothing about unpaid work, and nothing about environmental cost. Inflation is a general rise in prices, which erodes savings and hurts people on fixed incomes most. India's economy is usually described in three sectors — agriculture, industry and services — with services now the largest share of output while agriculture still supports the most people.
