The present study is provoked by the idea of revealing the influence of the factors of both the internal environment of wine-producing enterprise and the factors of the external macro environment. The subject of study are the factors influencing the activity of wine producers located in the North Central, South Central and Southeast planning regions. The object of study are the economic entities on the market that produce and offer wine from the subsector “Wine Production” in three geographical regions of Bulgaria - North Central, South Central and Southeast. The aim of the research is, as a result of theoretical and practical research, to establish the influence of various factors, grouped in a certain way, on the development of wine production in the North Central, South Central and Southeast regions. The study attempted to combine the two approaches and as a result of the information, a cluster analysis was performed to classify enterprises on the basis of five selected objective indicators - net working capital, income / expense ratio, turnover ratio of non-current assets, turnover ratio, current assets and rate of return on sales revenue. As a result, a difference in geographical location was reported only for enterprises in the South-East region. The factor analysis was conducted on the basis of the subjective perceptions of the respondents about the economic condition of their enterprise and the factors belonging to the macro environment. As a result, recommendations are made for improving the business environment and the relationships among the individual contractors at the appropriate level - company, region, country.

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.
