  OPTIMIZING THE EFFECTIVENESS OF DIRECT MARKETING CAMPAIGNS USING DATA MINING

  In this article several data mining models, together with the conventional RFM model, are designed and applied for optimizing the effectiveness of direct marketing campaigns. Regardless of its popularity as a means for generating “optimal” target lists, RFM analysis is far from optimal solution. Applied on empirical data for one-year activities of ... In this article several data mining models, together with the conventional RFM model, are designed and applied for optimizing the effectiveness of direct marketing campaigns. Regardless of its popularity as a means for generating “optimal” target lists, RFM analysis is far from optimal solution. Applied on empirical data for one-year activities of an e-shop of electronic and home appliance technique, all data mining models surpass RFM model in predictive performance.

  INVESTIGATION OF THE RELATION BETWEEN EXTERNAL COSTS AND ECOEFFICIENCY

  The development of reliable methodologies for assessing the harmful effects of production and consumption of goods and services on the environment is a major challenge to the scientific community. Along with the existing indicators, indexes and other measurement tools, in recent years relevant quantitative methods for evaluating these influences ... The development of reliable methodologies for assessing the harmful effects of production and consumption of goods and services on the environment is a major challenge to the scientific community. Along with the existing indicators, indexes and other measurement tools, in recent years relevant quantitative methods for evaluating these influences have become increasingly popular and much used. By increasing the reliability of these methods the topical question of how they are integrated into the assessment of eco-efficiency of goods and services has been put forward. The aim of this project is to offer a scheme using external environmental costs in the evaluation of eco-efficiency. For that purpose, after a detailed analysis of the results taken from various sources, this project offers the basic steps of the integrated circuit, as well as different approaches for assessing eco-efficiency at macro level, and the software used for this purpose and support systems for decision-making. Computations have been performed and concrete results have been obtained.

  BUSINESS CYCLE SYNCHRONIZATION OF THE EUROPEAN UNION MEMBER-STATES: A STUDY OF THE ECONOMIC CONVERGENCE WITHIN THE EU

  The aim of this paper is to investigate the level of business cycle synchronization of the EU member states. Three macroeconomic indicators within EU members are studied – GDP, unemployment and inflation. The methodology of the study is based on two parallel econometric techniques – Baxter-King and Hodrick-Prescott filters. Different levels of ... The aim of this paper is to investigate the level of business cycle synchronization of the EU member states. Three macroeconomic indicators within EU members are studied – GDP, unemployment and inflation. The methodology of the study is based on two parallel econometric techniques – Baxter-King and Hodrick-Prescott filters. Different levels of synchronization are distinguished within the estimated indicators – high s synchronization of GDP, moderate of unemployment and low synchronization of inflation. Different levels of synchronization are identified between the old and new members of the EU.
