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.

  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.

  MODELS FOR BUILDING LOGISTICS CHAINS IN AGRIBUSINESS

Characteristic of Bulgarian agriculture is the presence of many, mostly small and medium-sized agricultural enterprises, occupying an insignificant market share, which operate in the highly competitive market of agricultural products. This fragmentation challenges agricultural holdings to improve their competitiveness and imposes a realistic orientation towards market innovations, including the formation of logistics chains. Building and improving logistics models is essential for optimizing business processes and generating added value in the sector. In this regard, the main research goal is to construct logistics models applicable in agribusiness. The research defends the thesis that the construction of logistics chains is a market reaction of the business for effective utilization of available resources and generation of added value, contributing to cohesion among the regions in Bulgaria. The results of the study can be systematized in the following areas. First. Based on the surveyed 212 business organizations from different business sectors and 47 agricultural companies that support Internet platforms in carrying out their activities, the main problems facing the business have been outlined and good logistics practices have been identified. Second. Based on a benchmarking study, the strengths and key problems related to logistics in the analyzed organizations were identified. Third. Applicable in agribusiness models have been constructed for the leading sectors of logistics - Transport, Warehousing and Processing and Finishing, depending on the capacity of the organization.
