There are numerous reasons behind their methodological difficulties. The most important ones are: – Differing perceptions of values for evaluating investment projects and for estimating the social value of a resource. – A varied level of values depending on the time of resource exploitation and its introduction into the economic and financial turnover (the present value and the option value of a resource). – Lack of valuation methodologies with a relevant degree of universality for these applications.
