  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.

  COMPARATIVE ANALISYS OF THE BULGARIAN AND ROMANIAN EXTERNAL SECTORS

  Being an area of free movement of “people, goods and capital”, EU gives both Bulgaria and Romania opportunities to improve their access to markets, as well as to attract more foreign direct and portfolio investments. The global economic crisis, that began two years after the two countries’ full EU accession, is likely to discontinue these ... Being an area of free movement of “people, goods and capital”, EU gives both Bulgaria and Romania opportunities to improve their access to markets, as well as to attract more foreign direct and portfolio investments. The global economic crisis, that began two years after the two countries’ full EU accession, is likely to discontinue these advantages and to pose serious hardships to the ability of their economies to function in a crisis and reduced cash flows. The project “Comparative analisys of the Bulgarian and Romanian external sectors” is focused on studying the trends in the balance of payment of the two countries and its components in the light of Euro membership and under the conditions of an economic crisis. Its scope includes the key specifics of trade and capital flows as well as the correlations between them. The views on balancing the external sector are generalized and tools are identified to assess the trends in the balance of payment.
