Local governments in the Western Balkan countries are dependent on central governments’ transfers, with low fiscal autonomy and limited efforts for own-source revenue mobilisation. The paper identifies that besides central government transfers, other significant factors in determining municipal own-source revenues include central and local public investment, current expenditures, human development index, and population density. Municipal own-source revenue is adversely affected by intergovernmental transfers, implying their de-incentivising effect in collecting local revenues. Local capital expenditure is a significant and strong determinant with a higher strength than central government investments, suggesting their importance for local fiscal autonomy. The human development index as a composite measure, unlike GDP per capita, positively affects the municipal fiscal autonomy.
