Abstract
To contract out public services or deliver them internally? Transaction costs, as part of the total costs for a public service, should represent an important factor when choosing how a public service should be delivered. Despite this, previous domestic and foreign literature shows that oftentimes, the service provider is unable or unwilling to calculate these costs, even if it might result in finding the most effective service delivery option. The goal of this paper is to analyse the situation in Slovak municipalities regarding transaction costs associated with public procurement and producer monitoring for the service of municipal waste management. The primary data from 254 Slovak municipalities, obtained through an online questionnaire, reveal a certain level of ignorance regarding transaction costs, as most municipalities were unable to provide the necessary data required to calculate the transaction costs associated with the selected service.
