  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.

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.

  STATISTICAL DIMENSIONS OF REGIONAL DIFFERENCES AND INEQUALITIES BETWEEN NORTH AND SOUTH BULGARIA

Nowadays, the implemented regional policy is invariably related to adopting a certain concept and setting specific goals to limit the economic, social and demographic differences in the country. The present paper is a theoretical and applied study. The theoretical problems are related to the demographic, social and economic processes as objects of statistical study of the NUTS 2 regions of North and South Bulgaria for the period 2004-2018. The applied aspect of the study is a thorough analysis of the economic, social and demographic situation of North and South Bulgaria. The purpose of this study is to theoretically justify and empirically estimate the regularities in the demographic, social and economic situation of North and South Bulgaria and to identify the regional differences and inequalities based on a statistical analysis of the dynamics, structure and their factor determination. To achieve this goal, the following main tasks are performed: characterizing the nature and theoretical concepts of inequality; presenting the methodology of the statistical survey of the regional differences between North and South Bulgaria; identifying the regularities in the demographic, social and economic development of North and South Bulgaria; classifying the areas according to their geographical location using discriminant analysis. The research thesis advocated by the authors and confirmed by the results is that improving the functional and spatial connectivity between the regions in North and South Bulgaria will lead to reducing the economic, social and demographic differences and inequalities between them.
