gross national product

Gross National Product (GNP) measures the aggregate value of final goods and services attributable to the normal residents (nationals) of a country during an accounting year, irrespective of whether that production occurs within the domestic territory or abroad. It is derived from Gross Domestic Product (GDP) by adding Net Factor Income from Abroad (NFIA) — the difference between factor incomes (wages, rent, interest, profit) earned by a country's residents abroad and factor incomes earned by foreigners within its domestic territory. The defining algebraic identity is GNP = GDP + NFIA. Where a country's residents earn more abroad than foreigners earn within it, NFIA is positive and GNP exceeds GDP; for labour-exporting, remittance-receiving economies the relationship is straightforward, while for economies hosting large foreign capital the NFIA is typically negative. The concept rests on the residency principle of the System of National Accounts (SNA 2008), the international standard administered by the UN Statistical Commission, IMF, World Bank, OECD and Eurostat.

In national-accounts methodology, GNP can be computed by the product (value-added), income, or expenditure approaches, all of which converge on the same figure net of statistical discrepancy. From GNP, two further aggregates are derived: Net National Product (NNP) = GNP − Depreciation (consumption of fixed capital), and National Income, which is NNP measured at factor cost (NNP at market price minus net indirect taxes, i.e. indirect taxes minus subsidies). The distinction between market price and factor cost valuations, and between gross and net (the deduction of depreciation), is central to all national-income arithmetic. GNP at market price is the headline residency-based aggregate; NNP at factor cost is the textbook definition of "national income."

Significantly, the SNA 2008 and the 1993 revision replaced the term "Gross National Product" with Gross National Income (GNI) as the standard nomenclature, since the magnitude is fundamentally an income aggregate rather than a production one — GNI and GNP are numerically identical. India's national accounts, compiled by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation, with the base year revised to 2011–12, now report GNI rather than GNP, and the World Bank classifies economies into low-, middle- and high-income groups using GNI per capita computed by the Atlas method. For an economy like India with substantial worker remittances, GNI tends to exceed GDP modestly, whereas for economies such as Ireland — distorted by multinational profit repatriation — GNI falls well below GDP.

For the UPSC examination, GNP is tested in General Studies Paper III (Indian Economy) and the optional Economics paper, almost always through the chain of national-income aggregates: candidates must convert fluently between GDP, GNP, NNP, national income, and personal/disposable income, and apply the market-price versus factor-cost and gross versus net adjustments. Prelims questions frequently ask which aggregate uses the residency versus territory principle (GNP/GNI is resident-based; GDP is territory-based), the precise role of NFIA, and the renaming of GNP as GNI under SNA. A common trap is conflating GDP and GNP for remittance economies; aspirants should anchor answers in GNP = GDP + NFIA and the depreciation/indirect-tax deductions that yield national income.
