Peculiarities of Risk Concept Formation

Summary/Abstract: The paper analyses the essence of risk concept in the context of social sciences, focusing on risk contents in investment science. The classic distinction between risk and uncertainty concepts is presented; the relation of risk with reliability (guarantee) is disclosed. Various possible measures of risk are also analysed, providing the features a coherent risk measure should possess. After thorough investigation of various scientists’ points of view, a definition of risk as an extent of loss for the subject is being proposed. While describing possible loss with the help of probability distribution, an accumulated distribution function is proposed for measuring and expressing the extent of loss, presenting the parameters of probability distribution as stochastic values.
