Under the influence of the instruments and mechanism of the economic policy, differences in the development level have been reproduced, making this way new political and ethnic tensions. The influenced unemployment problem in Kosova has marked a backwardness in development and application of the equality with other nations of former Yugoslavia. From the national product per capita tendencies, it is noticed that the developed have protected their dominant positions in the economic system of former Yugoslavia. Even just before the dissolution of former Yugoslavia, the developed federal units, in terms of development, were prepared to gain their independence.
The influenced economic problems in former Yugoslavia on one side, and evident problems in functioning of the economic system on the other, were a permanent source of conflicts, which occurred due to the significant differences in development level between the federal units. The difference between the two extremes, Slovenia and Kosova was 1:7, while the difference with the average of Yugoslavia or Serbia was almost 1:4. In these relations, the creation of the economic policy and its application became very difficult, because obviously in the platform of such significant differences, the measures of the economic policy and economic regulation, were expressed by different effects in different regions and federal units. So this was a source of permanent economic interest conflicts. In a situation of a very heterogenous national structure of these units, these conflicts got a national color and were a permanent source of the increased nationalism and disintegration tendencies. The developed parts of Yugoslavia were not satisfied with the activity of economic system mechanism, considering that they are providing too much funds for crediting and help for the undeveloped. Undeveloped parts considered that these funds were not sufficient in order to reduce the differences in development, having in mind that with other mechanisms (financing of exports which was mainly concentrated to the developed parts), or by a combined activity of the system of price control and foreign trade, they were losing more than they were winning. This was one of the most essential conflicts in the Yugoslav federation.
This situation was expressed also in Kosova, reflected in the creation of unsatisfactory situations among young people, who claimed a faster progress. This was one of the most significant problems in the eighties, which was reflected also in the demonstrations of 1981. From the experience of former Yugoslavia, it can be concluded that in the conditions of the significant differences in economic development of the different subjects within a country, in cases of the multinational proportions, and historic problems, the economic conflicts could be transformed into national and political problems, thus making a permanent disintegration focus. Therefore, it can be concluded that, under these circumstances, the centralized economic system cannot offer any solution nor economic efficiency, but it rather maintains and reproduces such problems. Independent economic systems could be a solution, as well as promotion of the economic cooperation in the fields of real economic interests. This experience should be considered during the negotiations procedure for any solution of the problem of Kosova and its relations with Serbia.
