Quarterly Gross Domestic Product (QGDP)

Quarterly Gross Domestic Product at market price (QGDP), the main macro-economic aggregate of national accounting, represents the final result of production activity for resident productive units, for a certain period, a quarter, respectively.

NIS compiles national accounts data according to international standards (SNA 2008), EU regulations on national accounts (ESA 2010), and Eurostat, OECD and IMF handbooks and recommendations. Data for GDP and main aggregates are regularly expressed in current prices and in prices of previous year (PYP) as well as in chain link volumes (CLV).Compiling national accounts in CLV, as opposed to nominal GDP (in current prices), allows accurate estimations of real GDP and GDP growth rates across years and quarters, which is helpful for economic analyses.

For quarterly national accounts, NIS Romania applies the annual overlap technique in compiling the chain linked quarterly data, as recommended by Eurostat.

Quarterly Gross Domestic Product is estimated in current prices, in the prices of the corresponding period of the previous year and in chain-linked volumes with reference year 2020. Chain linking with base year 2020 is compiled by linking the volume indices by the annual overlap technique, according to Eurostat requirements. For supllementary information please the document "Methodological note on change of chain-linked reference year in Romanian National Accounts.

Besides the gross estimates of quarterly Gross Domestic Product, seasonally adjusted estimates are also compiled, based on the regressive method, this method being recommended by the European regulations.

The seasonal adjustment envisages the removal of seasonal effects from the data series in view to highlight the real economic evolution during consecutive periods. In order to adjust the main aggregates series, based on which the GDP is estimated by all three methods, JDemetra+ software package is used (X-13ARIMA-SEATS method or TRAMO-SEATS method). The obtained seasonally adjusted series are used to compile the growth rates for GDP and its components.

The revision of the quarterly accounts data is periodically done, when a new version of yearly national accounts is available. The revision of data has as objective to keep the coherence between the quarterly accounts and the yearly accounts. The periodical revision of national accounts unadjusted data series also entails the revison of seasonally adjusted series.
