This book examines the impacts of fiscal decentralization reforms on the efficiency of local governments in Central and Eastern European (CEE) countries. By offering a comparative perspective and by applying econometric methods and regression models, it analyses various reform trajectories and their effects on individual CEE countries. Furthermore, the book discusses input and output indicators for evaluating the efficiency of municipalities. Readers will learn about the common features of these countries, the impact of path dependence, and future prospects for decentralization reforms. In closing, the book discusses modern management and administration methods, opportunities for cooperation between municipalities, co-creative service delivery, and other measures that could improve the efficiency of public service provision.
