Justification of the choice of the concession mechanism for projects economically efficient for the infrastructure owner

In modern economic realities, the state is playing an increasingly important part, managing the economy to achieve greater social efficiency. From this standpoint, the crucial aspect of efficient application of the concession mechanism is the selection of project proposals that have socio-economic practicality. The purpose of the paper is to justify the choice of the concession mechanism for projects economically efficient for the infrastructure owner. The authors conclude that upon justifying the choice of the concession mechanism, it is important both to analyse the economic efficiency with the benefit of the best analytical practices of investment management in conjunction with budget efficiency evaluation and to assess the specific risks and probability deviations, factoring in the specifics of projects on creation of public railway infrastructure in order to evaluate and subsequently monitor the comparative advantages of the concession over the state law and other PPP tools.
