This article looks at recently published research on social media consumers. Five topics are highlighted: consumer digital culture, responses to digital advertising, the impact of social media on consumer behavior, mobile environments, and online rumors (WOM). The articles examines how consumers experience, are influenced and are influenced by the digital environment they are in as part of their daily lives. Much remains to be understood, and existing knowledge tends to focus disproportionately on WOM, which is only part of the digital consumer experience. Several avenues for future research have been proposed to encourage researchers to consider a wider range of phenomena.

This article is devoted to the creation of intelligent modelling tools for decision support in the evaluation of intellectual projects submitted for financing, as based on qualitatively defined characteristics. The economic and mathematical models that form the basis of the toolkit are constructed using the mathematical apparatus of fuzzy logic, which allows for the description of poorly structured knowledge of specialists, as well as their application in solving questions about the extent of the impact of the proposed projects on the environment. The authors classify investment projects according to the degree of impact on the environment, the environmental criteria required by the investor for the evaluation of investment projects, and the formal formulation of the problem of evaluation of investment projects when taking into account the environmental factor. The toolkit was created based on the concept of intellectualization, where economic and mathematical models for the evaluation of investment projects are programmatically implemented via the tools and functions available in the MATLAB package.

The article deals with the problem of adaptation of the Russian oil and gas company (Novatek, Russia) to the rapidly changing external environment, the avalanche of data from competitors, and the need to filter important information for business development and the prosperity of the industry as a whole. The approach is based on the system of integrated software monitoring of key business processes at the enterprise developed by the authors—from the formation of the idea of a new product to its implementation to paying customers. The scientific novelty lies in the use of an optimization model that allows for minimizing the maximum losses of the investor at all levels of decision-making, from the distribution of capital between companies, to the optimization of internal reserves to increase the competitiveness of the company. The toolkit is a minimax model that allows you to redistribute the shares of investor influence at the portfolio level, and then within the business processes of each company selected by investors, in order to achieve the optimal solution in accordance with the selected estimated indicators. Application of the well-known portfolio investment models of Markowitz, Tobin, Sharp, etc. is not possible due to the lack of necessary data on the basis of which the probabilistic parameters involved in the model are estimated. Even if we get them, it is necessary to take into account the level of correlation influence of the technological process in the composition of each subsystem, which is unacceptable for the data used, as it leads to a strong increase in errors. Using minimax and a systematic approach allows you to minimize such errors by choosing a balanced concentration of distributed assets for both the investor and the buyer. To this end, a three-way analysis of the company’s development was carried out and a technology for comprehensive improvement of the company’s activities was developed in the following areas: the company’s rating in the industry, financial condition, and interaction with counterparties using merchandising technologies. Tools for optimal image zoning at the Novatek site using the minimax approximation criterion have been developed. The technology provides a procedure for creating a comfortable mode of image perception based on high-tech visualization of merchandising, zoning of the screen area, and a mathematical approach that allows you to develop a calculation algorithm.

Investor expectations, rather than fundamentals, are increasingly influencing the value of a company. At a time when nonfinancial assets are becoming an important component of determining the value of the company, the disclosure of non-financial statements as a source of more extensive and meaningful information than financial statements, is becoming an increasingly popular topic of discussion of the scientific and business communities. Non-financial reporting includes "various types of external reporting provided by organizations to their stakeholders and covering those aspects of the organizations that go beyond the historical framework of financial performance". The information contained in non-financial reports can help investors form an opinion about the intellectual, financial, natural, human and social capital of the company and make a decision about investing. In the developed world, the publication of nonfinancial statements has become a common norm, while in Russia only a small proportion of companies still issue this type of reporting. The study of publishing non-financial reports dedicated to both theoretical and empirical literature, most empirical studies showed a positive effect of issue of non-financial reporting on the financial stability of companies. However, these studies do not focus on the impact of the publication of non-financial statements on the financial performance of companies in Russia. The purpose of this article is to study the impact of the publication of non-financial statements on the financial performance of Russian companies with the identification of intersectoral features. As a result of this study, it will be possible to understand how the disclosure of non-financial information affects the financial performance of Russian companies. From a practical point of view, this can help managers of companies in various industries to realize the importance or, conversely, the absence of the need to publish non-financial statements as a factor that can increase the credibility of the company in the eyes of investors and positively affect the financial results.
