This study systematizes the theoretical foundations of mathematical modeling of consumer behavior in the choice process in the context of random utility theory. The main attention is paid to some aspects of econometric estimation of discrete choice models. The main thesis is that based on the theory of random utility, you can create tools for predictive analytics of demand. The aim of the study is to develop a transpar-ent and traceable analytical methodology for analyzing empirical data from stated preferences, providing opportunities for evaluating, analyzing and predicting consumer choice. To achieve this goal, a brief synopsis of the discrete choice theory was made, as well as a review of methods for evaluating and analyzing traditional econometric mod-els with discrete dependent variables. Particular attention is drawn to the problems in specifying adequate binary and multinomial regression models, which are the core of analytical tools, and whose evaluation and verification is feasible with the help of open source software. Systematizing achievements in the field, recommendations are given for using predictive models for solving marketing problems. Methods for predictive analytics of consumer choice are proposed, including output of aggregated forecast estimates, building of market simulators for predictive modeling of market share, as-sessment of willingness-to-pay and price elasticity at the level of product alternatives.

  OPPORTUNITIES FOR OPTIMIZING THE REGIME OF PAYMENTS FROM THE STATUTORY PENSION INSURANCE FOR DISABILITY IN BULGARIA

  An attempt has been made to argue the thesis that in the conditions of an unfolding system of social payments and coordinated institutional interaction within the framework of social protection, there is a need to rethink the social philosophy of disability benefits provided by the statutory pension insurance.

An attempt has been made to argue the thesis that in the conditions of an unfolding system of social payments and coordinated institutional interaction within the framework of social protection, there is a need to rethink the social philosophy of disability benefits provided by the statutory pension insurance. The study of opportunities for development of the organizational framework of public pensions for labour activity in case of disability, in the context of the systemic nature of social payments in Bulgaria, is also the main aim of the research, in the connection with which the following specific tasks are set: study of the theoretical and methodological aspects of social security and social protection systems in modern society; study of the practical and applied aspects of social security and social protection systems in modern society; study of the specifics of disability protection in the context of risk differentiation of social protection systems; study of the national identity and the social insurance profile of the disability protection in Bulgaria and assessment of the need and opportunities for development of the organizational framework of payments from the statutory pension insurance for disability in Bulgaria. The results of the research enable to outline guidelines for optimizing the organizational framework of payments from the statutory pension insurance for disability in Bulgaria with the potential to increase the level of pensions within the available resources.

  INTEGRATED REPORTING IN THE MANAGEMENT OF ENTERPRISES IN BULGARIA

  The concept of integrated reporting is relatively new for the practice of enterprises both nationally and internationally. The fact that the Integrated Reporting Committee was established in 2010, which issued the International Integrated Accounting Framework in 2013, is indicative that the concept of integrated reporting is relatively new. The ... The concept of integrated reporting is relatively new for the practice of enterprises both nationally and internationally. The fact that the Integrated Reporting Committee was established in 2010, which issued the International Integrated Accounting Framework in 2013, is indicative that the concept of integrated reporting is relatively new. The essence of this paradigm is to cover the impact not only of phenomena and processes measurable by monetary equivalent, but mainly of events with indirect financial effects, which, however, are crucial for the future development and stability of enterprises. The object of research in this publication is the application of integrated reporting in the practice of enterprises in the non-financial, banking and public sectors in our country. The subject of the study includes the practices related to the disclosure of information from the integrated reporting in the annual reports of the enterprises from the economic sectors indicated in the object of the study. The main goal is on the basis of theoretical studies of the specialized literature and research of practice related to the integrated reporting of enterprises from different sectors of the economy in Bulgaria, to outline the problems and to bring possible solutions to improve the quality of reporting information.
