Usually, the total amount of funding requested in all governmental budget requests is approximately two to three times more than the available government income (Chalongpop, 2003: 151). To allocate budgets in line with the determined budget ceiling, the amount of the proposed budget of every agency is reduced by the Bureau of the Budget. The budget reduction is based on compromises and the negotiations between government agencies and the Bureau of the Budget (Chalongpop, 2003: 151-152).
