The analysis of literature on liberalisation of the services reveals that public goods, public institutions, privatisation and liberalisation have become the main subject of studies and different debates of the economists, politicians, as well as theoreticians and practicians of public administration during the last century. In the course of the period, there have been changes both in theoretical ideas and practical solutions while providing public services. During the last thirty years, theory of the public goods has involved topics of the analysis on the liberalisation and privatisation processes. Most of the studies related to the liberalisation of the services have been concentrated to financial aspects (expenses and income), while social benefits of the liberalisation, such as public interest, equality, versatility and accessibility of services, transparency, social cohesion and justice, have been left in the background.
