  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.

  THE BANKING SECTOR IN CRISIS

  Banking crises are costly for the economic crises, not only because of the high direct rescue costs, but also due to the negative effects on the economy by limiting the access to credit resources, negative impact on the price of government debt and securities of local companies, as well as a possible devaluation of the national currency. The aim ... Banking crises are costly for the economic crises, not only because of the high direct rescue costs, but also due to the negative effects on the economy by limiting the access to credit resources, negative impact on the price of government debt and securities of local companies, as well as a possible devaluation of the national currency. The aim of this study is to clarify the causes and transmission mechanisms of the global financial crisis of 2007, and to advocate the following idea: effective risk management in the financial sector at the international level is the only way to prevent future global financial crises. In this context, the following main tasks are defined: (1) factors for the occurrence of banking crises, and in particular – the global financial crisis of 2007, (2) transmission mechanisms of infection in the international banking sector, (3) the impact of the global financial crisis on the banking sector, and (4) policy options for risk management in the banking system and for strengthening it.

  EXPLORING THE POSSIBILITIES FOR IMPROVING THE COMPETITIVENESS OF BREWERIES IN BULGARIA

Contemporary realities and the transition to a new civilizational model of development – “Knowledge-based economy” modify the ways of achieving competitiveness of enterprises. ICT, innovations and human capital are becoming major factors of corporate progress. The three listed pillars determine relevant changes in the sectoral structure of Bulgaria, especially in the brewing sub-sector; in the “architecture” of its competitive intensity and in the formation of its competitive advantages. In this respect, the purpose of this particular project study is to assess and analyze the competitiveness of Bulgarian enterprises in the brewing sub-sector at present and in the future. The paper advocates the idea that in order for the breweries in Bulgaria to be highly competitive, they have to intensively use ICT, actively implement innovations and constantly broaden and enrich the knowledge of their staff. The assessment (based on surveys and direct interviews) of the competitiveness of national brewers reveals their state and “bottlenecks”, defines the main conclusions and outlines recommendations for their effective development and growth.
