Statistical revisions, expenditure over-runs associated with organising the Athens Olympics and other spending items, and revenue shortfalls have been blamed for the budget gap.
Revizuirile statistice, depăşirile cheltuielilor estimative asociate cu organizarea Olimpiadei de la Atena şi alte costuri, precum şi veniturile scăzute, au fost considerate principalele cauze ale deficitului bugetar.
