dc.description.abstract
We measure the Data Quality (DQ) of official National Accounts (NA) data that
are published at the international level. Measured are availability,
timeliness and reliability. We make first time assessments of the “actual”
timeliness of data publication at the UN level; of the data availability
regarding the 2008 Minimum Requirement Data Set (MRDS); and of the data
reliability of 12 OECD and 4 non-OECD countries. The existing UN timeliness
assessment does not reflect how many years a country needs to produce the
reported data. The UN availability assessment only covers the old MRDS, not
the new MRDS (valid as of 2014). The reliability assessments according to the
OECD recommended methodology cover major comprehensive revisions and analyze
Quarter-on-Quarter (QoQ) growth rates, disregarding that some data are non-
seasonally adjusted. We assess timeliness at the first time publication of
data at the international level. This indicates the time lag of data
production at the country level. Over 90% of the county data indicate either
no time lag or at most one year. With our timeliness and availability
assessments, we can identify the performances of economic and geographic
regions and other country groups. For research our timeliness assessment
informs about the time point (in years) when data for a specific reference
year becomes available at the UN. Further, IOs can identify country groups
that potentially benefit from technical assistance. Our availability study
reveals that 55% or the UN Member States fulfill at least all but one of the
1993 MRDS criteria, but only 27% do so regarding the 2008 MRDS criteria. That
means the availability of detailed data, precisely the institutional sector
accounts until “net lending” of the capital account, is much lower than of
basic NA data. Government sector accounts are compiled by nearly 90% of the
developed countries, the total economy by more than 80%. However, other
institutional sectors (both of the households and non-profit institutions
serving households, or the individual non-financial and financial sector
accounts) are often missing. Besides the developing regions even developed
regions need improvement. More non-G20 advanced economies than G20 countries
fulfill the 2008 MRDS. The availability study also covers the fulfillment of
milestone levels one and two, indicating the progress of countries’ NA data
production. For our reliability study, we use Year-on-Year (YoY) growth rates
of quarterly GDP. We eliminate revisions across SNA versions. Our study
reveals higher reliability of the data than previously assessed. Our
international comparison considers for the first time 34 countries. The study
informs decision makers about the reliability of data at the different release
time points. The considered revision measures are Mean Absolute Revision (MAR)
and Relative Mean Absolute Revision (RMAR). The latter is better suited for
cross-country comparisons. For most countries the size of MAR of the first
estimated YoY growth rate of GDP to the three years later published value is
less than 1 percentage point. For the 30 OECD countries, the RMAR of the first
to the three years later vintage is an average 22%. Countries with rather
small size of MAR in percentage points may substantially revise the data
relative to its size.

dc.description.abstract
Wir untersuchen die Datenqualität (DQ) bezüglich Aktualität, Verfügbarkeit und
Zuverlässigkeit von Daten der Volkswirtschaftlichen Gesamtrechnung (VGR) die
von Ländern an internationale Organisationen gemeldet und dort veröffentlicht
werden. Die existierende DQ Untersuchung der Vereinten Nationen (VN) für
Aktualität reflektiert nicht die Zeit (in Jahren) die seitens der Länder
benötigt wird um diese Daten zu produzieren. Die Untersuchungen der VN zur
Verfügbarkeit legen den alten „Mindestdatensatz“ [„Minimum Requirement Data
Sets“ (MRDS)] zu Grunde. Die Untersuchungen zur Zuverlässigkeit gemäß den OECD
Empfehlungen beinhalten Revisionen über verschiedene SNA Versionen und
untersuchen Wachstumsraten im Vormonatsvergleich (QoQ). Unsere Aktualität
bezieht sich auf die Zeitperiode bis zur Erstveröffentlichung auf
internationaler Ebene. Dies ergibt den Zeitraum den die Länder zur
Datenproduktion benötigen. Unsere Ergebnisse zeigen, dass beinahe 90% aller
Länder Daten für das vergangene Kalenderjahr oder für das Vor-vorjahr liefern
(d.h. mit maximal einem Jahr Verzögerung). Anhand unserer Untersuchungen zur
„Aktualität“ und „Verfügbarkeit“ lassen sich die Kapazitäten verschiedener
Regionen und Ländergruppen identifizieren. Internationale Organisationen
können feststellen welche Ländergruppen von Hilfe zur Qualitätssteigerung
profitieren könnten. Datennutzer können anhand unserer Aktualitätsstudie
herausfinden in welchem Publikationsjahr Daten für welche Referenzjahre bei
den VN zur Verfügung stehen werden. Unsere Ergebnisse zur Verfügbarkeit
zeigen, dass 55% der VN Mitgliedsstaaten alle außer eines der 1993 MRDS
Kriterien erfüllen. Im Fall des 2008 MRDS sind es nur 27%. Dies bedeutet, die
Verfügbarkeit von einfachen VGR Daten ist höher als die der detaillierten,
präzise der Kontentabellen bis zum Indikator „net lending / net borrowing“,
d.h. bis zum „Finanzierungssaldo“. Diese Kontentabellen werden für den
Staatssektor von 90% der entwickelten Länder erstellt, für die
Gesamtwirtschaft von 80%. Andere Wirtschaftssektoren fehlen jedoch häufig.
Sogar viele entwickelte Länder müssen die Datenverfügbarkeit noch verbessern.
Mehr nicht-G20 Staaten erfüllen die 2008 MRDS Kriterien als Staaten der G20
Gruppe. Die Verfügbarkeitsstudie umfasst auch die Meilenstein Stufen eins und
zwei, die die Produktionskapazität unterschiedlicher VGR Konzepte durch die
Länder messen. Für unsere Zuverlässigkeitsstudie von BIP Quartalsdaten
verwenden wir Wachstumsraten im Vorjahresvergleich (YoY). Wir schließen
Revisionen über verschiedene SNA Versionen aus. Unsere Ergebnisse weisen
geringeren Revisionsbedarf der einzelnen Länder aus und somit eine höhere
Zuverlässigkeit der erstveröffentlichen BIP Daten. Wir analysieren erstmalig
34 Ländern anhand empirischer Revisionsdaten. Wir messen die Zuverlässigkeit
der erstveröffentlichten Daten gegenüber verschiedenen Revisionszeitpunkten.
Wir berechnen die Mittlere Absolute Revision „Mean Absolute Revision“ (MAR)
und die Relative Mittlere Absolute Revision „Relative Mean Absolute Revision“
(RMAR). Letztere ist besser geeignet für den internationalen Vergleich. Die
MAR vom erstveröffentlichen zum drei Jahre späteren Wert ist für die meisten
Länder kleiner als ein Prozentpunkt. Die RMAR vom erstveröffentlichen zum drei
Jahre späteren Wert beträgt für die 30 OECD Länder durchschnittlich 22%.
Länder mit kleiner MAR können jedoch eine erhebliche RMAR aufweisen.
