The question asks about the first scientific attempt to estimate national income in India after independence. We need to identify the specific body or individual responsible for this post-independence estimation.
D) The National Income Committee (1949) under P. C. Mahalanobis was constituted by the Government of India in 1949 to compile estimates of national income. This marked the first comprehensive and scientific attempt to estimate national income in India after gaining independence.
The question asks to identify the first individual who attempted to estimate the national income of India. This is a factual question related to the history of economic thought in India.
Correct Option: D) Dadabhai Naoroji was the first individual to attempt the estimation of national income in India. He made his estimates for the year 1867-68, calculating the per capita income to be Rs. 20. His work is significant for highlighting the 'drain of wealth' theory, which argued that Britain was extracting resources from India, leading to its impoverishment.
The question asks to identify the specific organization responsible for estimating national income in India. This is a factual question related to the institutional framework of economic statistics in India.
C) National Statistical Office (NSO) under MoSPI is the organization currently responsible for the estimation of national income in India. The NSO, formed by the merger of the Central Statistical Office (CSO) and the National Sample Survey Office (NSSO), is the primary agency for collecting, compiling, and disseminating macroeconomic statistics, including Gross Domestic Product (GDP) and other national income aggregates.
The question asks for the best definition of National Income. To answer this, we need to understand the various macroeconomic aggregates and their definitions, particularly distinguishing between market prices and factor cost, and gross vs. net values.
A) NNP at factor cost is the best definition of National Income because it represents the net value of goods and services produced by the normal residents of a country, valued at the cost of the factors of production (i.e., excluding indirect taxes
National income is a measure of the total value of goods and services produced in a country over a specific period, usually a year. There are three main methods used to calculate national income, each approaching the measurement from a different perspective but theoretically yielding the same result.
These three methods are fundamental to macroeconomics and are used globally to estimate a country's economic performance.
B) Product, Income and Expenditure methods are the three universally accepted and widely used methods for measuring national income. They represent the three phases of the circular flow of income: production, distribution (income generation), and expenditure.
The value-added method, also known as the product method or output method, is one of the ways to calculate national income (GDP). It measures the contribution of each producing enterprise to the total output of the economy. The core concept is to avoid double-counting by only considering the value added at each stage of production.
Correct Option: B) Value of output minus value of intermediate goods
This option correctly defines value added as the difference between the total value of goods and services produced (value of output) and the cost of inputs purchased from other firms (intermediate goods/consumption) to produce that output. This precisely captures the new value created by a firm.
