Understanding GDP of India (by Be Money Aware Blog)

This is an excellent article written by Be Money Aware Blog on the basics of GDP interpretation and the mechanics behind that number. Here is the link to the original article.

Overview of GDP

GDP, or Gross Domestic Product, is the value of all goods and services produced in the economy over a period of time, normally a year. GDP is considered to be yardstick of measuring the functioning of the economy. GDP is usually expressed as a comparison to the previous GDP value in percentage. That is calledGDP Growth Rate. Usually yearly or quarterly GDP growth rates are used. To account for inflation two GDP figures are released one based on current prices called as Nominal GDP and other one based on base-year prices called as Real GDP. GDP can be calculated in many ways such as income approach, production approach, expenditure approach.

Who releases GDP numbers?

In India GDP is calculated by Central Statistical Office (CSO) which is part of Ministry of Statistics and Programme Implementation.  CSO introduced the quarterly estimates of GDP in 1999 as part of the requirements under the Special Data Dissemination Standard of the IMF. In India, the quarterly GDP releases with a delay of approximately two months with respect to the end of the reference period. For Instance- the data for Fourth Quarter(Jan-Mar) 2011-12 were published on 31st May 2012. MOSPI releases the Advance Release Calendar which is updated on 1st of every month. The Advanced Release Calendar for Year 2012-13 is shown below.

Central Statistical Office or CSO, a part of part of Ministry of Statistics and Programme Implementation,is responsible for coordination of statistical activities in India, and evolving and maintaining statistical standards. Its activities include compilation of National Accounts; conduct of Annual Survey of Industries and Economic Censuses, compilation of Index of Industrial Production, as well as Consumer Price Indices. It also deals with various social statistics, training, international cooperation, Industrial Classification etc.

Understanding GDP figures of India

Market Prices and Base Year Prices

Every time any GDP number is released, 2 different numbers for GDP are released, one for the base year prices which currently is 2004-05(Real GDP) , which are inflation adjusted prices and one for the current prices (Nominal GDP) or market price. Base Year keeps on changing. Change of base year from 1999-2000 to 2004-05 happened in n 29.1.2010 The reason for periodically changing the base year is to take into account the structural changes which have been take place in the economy and to depict a true picture of the economy through macro aggregates like GDP, consumption expenditure, capital formation etc. MOSPI:Brochure on the New Series of National Accounts, Base Year 2004-05 explains the change of base year to 2004-05.

Production and Expenditure Approach

As we know GDP can be calculated in many ways such as income approach, production approach, expenditure approach.  In India the two ways used are Production and Expenditure Approach. Ref:Onemint:How GDP is calculated (Dec 2011)

  • Production Approach: It breaks down the economy into different sectors such as agriculture, forestry, fishing, mining, manufacturing, electricity etc and then computes the value that has been added in each sector. This is reported as ESTIMATES OF GDP BY ECONOMIC ACTIVITY
  • Expenditure Approach: is calculated by adding what everyone has spent. A common equation for GDP calculation is:

GDP = Private or Consumer Consumption(C) + Government(G) + Investment (I)+ Net Exports(NX)

This is reported as ESTIMATES OF EXPENDITURES ON GDP

Quarterly, Cumulative Data

Along with the Data for each quarter the data is also reported for

  • Quarterly data of previous quarters of the same year: say if report if for Q3 or third Quarter Oct-Dec 2011-12, GDP numbers for Q1 (Apr-Jun), Q2 (Jun-Sep) of 2011-12 are also reported, as shown in the first figure GDP calculation using production approach given below.
  • Quarterly data of previous quarters of the two earlier years:  say if report if for Q3 or third Quarter Oct-Dec 2011-12, GDP numbers for Q1 (Apr-Jun), Q2 (Jun-Sep) of 2009-10, 2010-11 are also reported, as shown in the first figure GDP calculation using production approach given below.
  • Cumulative data of earlier quarters for this year: say if report if for Q4 or fourth Quarter Jan-Mar 2011-12, GDP numbers for entire year are reported as in figure 3 GDP using production approach showing annual(cumulative) data. Q2 report will have half-yearly data from Apr-Sep, Q3 report will have data from Apr-Dec.
  • Cumulative data of  earlier quarters for previous year: say if report if for Q4 or fourth Quarter Jan-Mar 2011-12, GDP numbers for year 2009-10, 2010-11 are also reported as in figure 3 GDP using production approach showing annual(cumulative) data

Interpreting GDP numbers

The information per-se is not in numbers but what story these numbers tell. NDTV: 10 things that numbers say (Jun 2012), Economic Times:Has GDP growth rate bottomed out?(Jun 2012) Hindustan Times:Anatomy of Slow Down (Jun 2012) details out the interpretations. The interpretation includes:

Understanding the living conditions

As onemint:A few thoughts on the GDP Numbers says breakup of GDP by economic activity shows

  • India went from being primarily an Agriculture economy to a Services economy, and missed the Industrial phase in between
  • A 19% agricultural share when close to three quarter of Indians live on agriculture is totally off balance.
  • Disparity that exists between Indians today.
  • We have one of the fastest growing economies, but we also have an unbelievably high number of people below the poverty line.
  • Developing a manufacturing sector is a must to bring millions of people out of poverty, and bridge this huge gap.

Understanding the Growth of Indian Economy

Wiki:Economic History of India covers how Indian Economy has been over the years.  Quoting from it:

India has followed central planning for most of its independent history, which have included extensive public ownership, regulation, red tape, and trade barriers. After the 1991 economic crisis, the central government launched economic liberalization. India has turned towards a more capitalist system and has emerged as one of the fastest growing large economies of the world

After independence from 1950′s to 1980′s India had growth rate around 3.5% called as Nehruvian Socialist rate of growth or Hindu rate of growth

Economic liberalization in India in the 1990s led to large changes in the economy.

Comparing India economy with other Asian countries

The graph shows GDP per capita of South Asian economies and South Korea as a percent of the American GDP per capita. Compare India (orange) with South Korea (yellow). Both started from about the same income level in 1950.

Questioning GDP data

Top policy makers, economists, rating agencies have questioned the robustness of the India’s GDP Estimates. Quoting from Times of India:Crisil questions GDP data (Jul 2011)

“Large revisions in GDP estimates in recent years have led to questions on the robustness of these estimates,” said Roopa Kudva, MD & CEO, Crisil. “As the most important economic indicator, GDP estimates influence policy making at the highest level, and hence the need for accurate estimation,” she added. Crisil study finds that the current method of computing GDP underestimates the size and growth of the Indian economy. The Crisil study comes on the heels of RBI governor D Subbarao questioning the series of revisions for a number of crucial data heads that are taken into consideration for major policy decisions, including the key policy rates by the central bank that decide the interest rate in the economy.

Dedication:This post is dedicated to Manshu of onemint.com who explained the concept of GDP’s in very simple terms to his readers and also provided the links to the reports. That helped a non-financial person like me to understand about GDP and even write an article on it.
