THE PROPOSED BUDGET FOR 2000

The proposed budget for 2000 is fully consistent with the four-year plan for 2000-03 ("Avança Brasil"), also submitted to Congress at the end of August 1999. This plan identifies the federal expenditure programmes that are to receive priority in the allocation of budgetary resources over the next four years, reflecting the main governmental objectives in the social, infrastructure and other public expenditure areas. It seeks to exploit regional and cross-projects synergies, and to attract partnerships with the other levels of government, the public enterprises, the multilateral development banks, and the private sector, to promote a more regionally balanced and sustainable development of the country. Increased emphasis will be placed on the evaluation of the results of these programmes, and on the accountability of the public managers of the programmes for these results.
