The aim of this study is to outline guidelines and recommendations for the implementation of the commitments under the EU directives related to climate change and energy efficiency, contributing to prosperity of the market and its sustainable development based on an empirical study of the state of real estate market in Bulgaria. To achieve the goal the following tasks are defined: clarification of the EU strategy on energy efficiency; outlining the place and role of real estate buildings in the country's economy; the development of a model for professional management of residential real estate buildings as a product provided by real estate agencies, able to foster increased energy efficiency. The main research thesis is that improving energy efficiency in buildings is essential for the stabilization and sustainable development of the real estate market by offering long-term benefits for owners and users of real estate.

  PRODUCTION AND MARKETS OF GENETICALLY MODIFIED ORGANISMS, FOODS AND AGRICULTURAL PRODUCTS

  This paper aims to study and find out the problems in the production and markets for agricultural products in terms of genetically modified organisms and genetically modified foods. To achieve this aim the influencing factors, defined in the tasks, are identified. The scarcity of land as a resource, the global economic crisis, food security, ... This paper aims to study and find out the problems in the production and markets for agricultural products in terms of genetically modified organisms and genetically modified foods. To achieve this aim the influencing factors, defined in the tasks, are identified. The scarcity of land as a resource, the global economic crisis, food security, global famine and some other factors make it necessary to create species sustainable to natural and climatic conditions, on the one hand. On the other hand, the insufficient information about how safe species are in terms of production, distribution and use of genetically modified organisms and foods requires state intervention. The agricultural sector is a strategic sector that requires the application of well-grounded economic measures by the government for seeking ways to control and eliminate potential negative consequences in terms of providing normal conditions for the existence of humans, plants and animals and protection of environment.

  PREDICTING DEMAND OF BUNDLED TELECOMMUNICATIONS SERVICES USING DISCRETE CHOICE-BASED MODELS

  This study explores consumer choice of bundled telecommunications services and empirically investigates some new possibilities of menu-based choice models for explaining and predicting the share of preferences. It demonstrates how to use menu-based conjoint analysis, aggregate multinomial logit and hierarchical Bayes models in order to estimate ... This study explores consumer choice of bundled telecommunications services and empirically investigates some new possibilities of menu-based choice models for explaining and predicting the share of preferences. It demonstrates how to use menu-based conjoint analysis, aggregate multinomial logit and hierarchical Bayes models in order to estimate part-worth utilities of attributes and price levels of digital telecommunications services for home users. A spreadsheet-based analytical simulation model for predictive analysis of the demand structure for alternative scenarios is composed based on empirical estimates of preferences. Our research purpose is to offer and demonstrate opportunities for optimal planning of product bundles that match the actual and potential customers’ expectations and willingness to pay.
