The growth rates seen in the constant local pricing series are preserved in our constant U.S. dollar price series. To make constant price averages, we convert each country’s constant local pricing data into constant 2010 US dollars, then sum by year with implicit gap-filling of missing values. Different nation weights in aggregations based on the values in the base year chosen would be reflected by rescaling to a different base year, however data for missing countries would have to be guessed. You can rescale 2010 data to 2005, for example, by first constructing an index that divides each year of the constant 2010 series by its 2005 value (thus, 2005 will equal 1). Then divide each year’s index result by the current U.S. dollar price value in 2005.
How is the GDP base year chosen?
The change in the base year reflects the actual changes in the economy’s structures. In a few months, the Ministry of Statistics and Programme Implementation (MOSPI) will choose a new base year for the GDP series. The ministry is working to introduce a new set of national accounts, which would result in the existing base year of 2011-12 being revised.
Despite the fact that the MOSPI is evaluating 2017-18 as the new base year, no decision has been made, and expert committees are awaiting further data before forming a judgment.
What happens if the base year is changed?
Changing the base period changes the viewpoint on what has happened, but it has no effect on the outcomes. The base year for significant economic indicators like the Consumer Price Index, Real Gross Domestic Product, and Producer Price Index is changed by the federal government on a regular basis.
What is the procedure for changing my CPI base year?
The Reference Base Period: An Overview (end value of CPI – start value of CPI)/ start value of CPI * 100 Equals percent change in CPI. Assume that the CPI in 2017 is 245.12 and 207.3 in 2007. To calculate the CPI increase from 2007 to 2017, subtract the CPI value in 2017 from the CPI value in 2007. The result is 37.82.
Why do we adjust the base year for GDP calculations?
According to him, the base year was altered in 1967, 1978, 1988, 1999, 2006, 2010, and most recently in 2015, when the base year was changed to 2011-12.
“This isn’t the first time the base year for estimating GDP has been altered.
“Even the United Nations System of National Accounts recommends that the base year be modified on a regular basis to incorporate the full rainbow colors of the economy into the mapping and to get a proper approximation of what is going on in the country’s GDP,” he said.
The rationale for the change in the base year was because the country’s socioeconomic environment had altered.
“Previously, there were teleprinters and typewriters, but now there are smartphones.” Like Ola and Uber, business models have shifted. He added, “There is a pricing dynamic because the price of computers has reduced.”
“The structural shift in the economy has been computed throughout multiple decades because the base year has been changed at numerous occasions,” he said, adding that there is no need for concern.
The minister responded to a follow-up question from Santanu Sen of the All India Trinamool Congress.
What is the new calendar year?
Of an economic or financial index, the base year is the first in a series of years. It’s usually set to a random value of 100. To keep data current in a given index, new, up-to-date base years are introduced on a regular basis.
Why did the base year fluctuate over time?
Every few years, the base year or reference year for assessing real growth is adjusted to ensure that the products and services used in GDP estimates accurately reflect the current state of the Indian economy. Aside from that, base year revisions include the incorporation of conceptual changes, methodology changes, and the addition of new and recent data sources.
For example, when the base year was changed from 2004-05 to 2011-12, the method industrial activity was measured changed. In comparison to the database supplied by the yearly survey of industries and other sources previously used, the government used a database of companies kept by the Ministry of Corporate Affairs, as well as other databases, to measure the sector’s growth.
What is real and nominal GDP?
The growth in the value of output in the economy adjusted for prices is referred to as real GDP growth. Nominal GDP is calculated by adding inflation to actual GDP. All budget calculations, including tax collection predictions and fiscal deficit computations, are based on nominal GDP.
What explains the controversy surrounding the GDP data?
The debate over GDP data began in November, when the government issued the controversial GDP data for the years prior to 2011-12, based on the new basis. Between 2005-06 and 2011-12, when the Congress-led United Progressive Alliance (UPA) was in power, the figures substantially reduced growth downwards. Many economists questioned how growth could have been scaled down systematically for all sectors in the back series data, prompting accusations of political intervention in data.
Furthermore, once the National Sample Survey Organisation (NSSO) pointed out several irregularities in the data, the use of the MCA-21 database in GDP calculations was questioned.
The most recent controversy was sparked by former chief economic advisor Arvind Subramanian’s article in The Indian Express on 11 June, in which he claimed that India’s GDP growth may have been overstated by 2.5 percentage points, with the economy growing at only 4.5 percent on average between 2011-12 and 2016-17.
Subramanian argued that real-world measures like energy usage, train freight, and airline passenger traffic differed from GDP estimates, implying that the manufacturing and informal sectors were over-estimated by statisticians, however the government quickly refuted his findings.
When the base year changes, what happens to real GDP?
The output of real GDP is weighed using prices from a base year. Real GDP accounts for changes in the total price level by measuring aggregate output at constant prices.
Why is 1982 the CPI’s starting point?
To put it another way, prices climbed by 2.6 percent. The CPI’s reference base was altered from 1967=100 to 1982-84=100 in 1988. The years 1982-1984 were chosen to match with the updated expenditure weights based on the Consumer Expenditure Surveys for 1982, 1983, and 1984.
