Show Summary Details

A number of assumptions have been adopted for the projections presented in the Regional Economic Outlook: Middle East and Central Asia. It has been assumed that established policies of national authorities will be maintained; that the price of oil will average US$107¼ a barrel in 2008 and US$100½ in 2009; and that the six-month London interbank offered rate (LIBOR) on U.S. dollar deposits will average 3.17 percent in 2008 and 3.10 percent in 2009. These are, of course, working hypotheses rather than forecasts, and the uncertainties surrounding them add to the margin of error that would in any event be involved in the projections. The 2008 data in the figures and tables are estimates. These estimates for 2008 and projections for 2009 are based on statistical information available through end-September 2008.

The following conventions are used in this publication:

  • In tables, ellipsis points (…) indicate “not available,” and 0 or 0.0 indicates “zero” or “negligible.” Minor discrepancies between sums of constituent figures and totals are due to rounding.
  • An en dash (–) between years or months (for example, 2006–07 or January–June) indicates the years or months covered, including the beginning and ending years or months; a slash or virgule (/) between years or months (for example, 2006/07) indicates a fiscal or financial year, as does the abbreviation FY (for example, FY2007).
  • “Billion” means a thousand million; “trillion” means a thousand billion.
  • “Basis points” refer to hundredths of 1 percentage point (for example, 25 basis points are equivalent to ¼ of 1 percentage point).

As used in this publication, the term “country” does not in all cases refer to a territorial entity that is a state as understood by international law and practice. As used here, the term also covers some territorial entities that are not states but for which statistical data are maintained on a separate and independent basis.
