National Income and GDP

National Income and GDP

National income measures the total economic output of a country. It indicates living standards, economic health, and guides policy decisions. GDP is the most widely used measure.

GDP

Gross Domestic Product is the total market value of all final goods and services produced within a country in a given period. Nominal GDP uses current prices; Real GDP adjusts for inflation (base year prices). GDP per capita (GDP/population) approximates living standards.

Measurement Approaches

Production approach: sum of value added at each production stage. Income approach: sum of all incomes (wages, rent, interest, profit). Expenditure approach: GDP = C + I + G + (X - M) where C=consumption, I=investment, G=government spending, X=exports, M=imports.

Economic Growth

Economic growth is the increase in real GDP over time. Sources: increased labour, capital accumulation, technological progress, and improved institutions. Growth rate is the percentage change in real GDP. Sustained growth improves living standards.

Business Cycles

Economies fluctuate between expansion (rising GDP, employment) and contraction/recession (falling GDP, rising unemployment). Phases: peak, contraction, trough, expansion. Fiscal and monetary policies aim to stabilise cycles.

Nepal's Economy

Nepal is a developing economy with GDP heavily dependent on remittances, agriculture, and services. Challenges include landlocked geography, infrastructure gaps, political instability, and vulnerability to natural disasters. Tourism, hydropower, and IT services offer growth potential.

Summary

GDP measures economic output and guides policy. Understanding measurement methods, growth drivers, business cycles, and Nepal's economic context is essential for applied economics.
