Abstract:
How does one compare economic data between countries that is expressed in units of national currency? And in particular, how should measures of production and Gross Domestic Product (GDP) be converted into a common unit? One answer to this question is to use market exchange rates. While straightforward, this turns out to be an unsatisfactory solution for many purposes – primarily because exchange rates reflect so many more influences than the direct price comparisons that are required to make volume comparisons. Purchasing Power Parities (PPPs) provide such a price comparison and this is the rationale for the work of the OECD and other international organisations in this field (see chart 1). The OECD publishes new sets of benchmark PPPs every three years, drawing on detailed international price comparisons. Every time a new set of benchmark PPPs is released, this also gives rise to a new set of international comparisons of levels of GDP and economic welfare.

2. Creation of the Euro Area: Implications for Economic Statistics

Abstract:
A major event in early 2002 was the arrival of the euro banknotes and coins and the withdrawal of the existing twelve national currencies from circulation. The event has influenced every citizen in the euro area and is clearly a historic change. It heralds a new phase in forging an “ever closer union among the peoples of Europe”. In economic terms, however, the introduction in January 1999 of the single currency after determining the irrevocably fixed exchange rates of the national currencies with the euro was a more important event. It meant that decisions on monetary policy moved from national central banks to the Governing Council of the European Central Bank. This Statistics Brief highlights some of the consequences for economic statistics of the creation of the euro area.
