One of the basic principles working in the European Union between the integrated individual member states is a programmatic reduction of differences in their economic level. It is based upon creating optimal conditions for the less developed countries to approach gradually the level of the economicly developed countries. For this purpose the financial funds are transferred by means of the EU budget in different forms: as a structural fund, regional fund, compensation fund etc. The membership in the EU implicates full participation in the redistribution funds of this kind. For the economicly extraordinarily developed countries it follows that they have to contribute to the EU budget (showing deficit, i.e. higher expenditures than receipts and, on the other hand, the countries economicly developed under the average level obtain net financial contribution from the EU budget (a surplus, i.e. higher receipts than expenditures). From the EU viewpoint the individual states as well as new candidates of the membership in EU must fulfil political and economic criteria. From the political point of view the countries must be with a democratic rule and reveal a political stability. From the economic point of view the countries must be characterized by a market economy, developed and going market economy institutions, balanced development and by the fact that their per capita economic level shall not be lower than that of the poorest EU countries. For the EU the extension with the EFTA countries is favourable: firstly, because the countries with an economic level higher than that of an average will significantly increase the economic contribution to the EU budget. Secondly, their stable economic and political structures will contribute to the internal EU stability. Thirdly, it is expected that the membership of these countries will contribute to acceleration of the European monetary union establishment. The countries of the Central and Eastern Europe have a different economic level compared with the EFTA countries. Central and Eastern European countries are not yet compatible with joining the EU common market working with free transfer of goods, services, capital and labour. The incorporation of the Central and Eastern European countries in the European monetary system presents another problem. The incorporation is not possible because their higher rate of inflation is not compatible with a fixed nominal exchange rate. Moreover, there is still a lasting pressure upon public expenditures drawn-down from the state budget, and an underdeveloped capital market in which the budgetary deficit is cumulatively increasing. The EU cannot monetarize deficits of these countries as it would disturb working of the monetary union. The situation requires a preceeding coping with inflation and budgetary deficits of the Central and Eastern European countries under the control of International Monetary Fond and the World Bank.
