The globalization and the free movement of people have an adverse effect on the own income of the municipalities in the country because of their depopulation and to a large extent, they depend on the state subsidies and transfers which seriously limits their independence.

Findings & Value added: The analysis allows us to make suggestions about legal changes and recommendations for more useful budgetary relations between the municipal budgets and the state budget.
