Economics: Development, Sectors, Money, and Public Finance
What the Economics section tests
Development, sectors, human development indicators, money and banking, public finance, and the Karnataka economy. Expect definition-plus-application: classify an activity, compute a simple indicator, or explain a policy effect.
Core rules
- Sectors: primary (agriculture, mining), secondary (manufacturing, construction), tertiary (services). GDP is the market value of final goods and services produced in a country in a year; GNP adds net factor income from abroad.
- Per capita income = national income ÷ population; it is an average and hides inequality.
- The Human Development Index combines life expectancy, education (mean and expected years of schooling), and per capita income.
- The Reserve Bank of India is the central bank: it issues currency, controls credit, acts as banker to the government, and is lender of last resort. The repo rate is the rate at which the RBI lends to banks.
- Deficits: revenue deficit (revenue expenditure exceeds revenue receipts); fiscal deficit (total expenditure minus total receipts excluding borrowings).
Worked example
A village sells ₹500 crore of milk, ₹300 crore of cheese, and ₹200 crore of transport services. Cheese uses the milk as an input. What is the sector-wise contribution to value added? Milk is primary, ₹500 crore; cheese adds ₹300 crore, but do not count the milk again inside the cheese; transport is tertiary, ₹200 crore. Name the sector and show the no-double-count rule.
Traps
Double counting intermediate goods; confusing GDP and GNP; calling the RBI a commercial bank; mixing revenue and fiscal deficits; assuming high per capita income means equal distribution.
