This paper considers barriers to the development of the sharing economy from the perspective of actors who are directly faced with the challenges of running a business. An original barrier classification model referred to as the two-phase neutrosophic Expert REputation RAting (ERERA) is formulated. Uncertainties regarding severity estimations of barriers and reputation appraisals of decision analysts are addressed using type-2 neutrosophic numbers (T2NNs). In the first phase, neutrosophic ERERA differentiates the decision analysts by taking into account their reputation indicators and built-in trade-off parameters. In the second phase, this innovative barrier classifier determines the severity degrees of the barriers and categorizes them by taking into account the nature of the addressed problem. The number of intrinsic parameters of neutrosophic ERERA equals the number of reputation indicators plus classification parameters, thus making it flexible for real-life multi-criteria group decision-making applications. Based on research conducted in Serbia, a set of critical severity barriers is found. In-depth sensitivity analysis confirmed the stability of the initial classes produced by neutrosophic ERERA. Funding, pre-opening requirements, and familiarity should be regarded as critical severity barriers to the sharing economy adoption in Serbia.
