The object of research in this study is the foreign exchange market, and the subject – the factors influencing the exchange rates of the leading world reserve currencies. The analysis focuses on the thesis of the increasing role of reserve currencies for the expansion of the transactions on the foreign exchange markets while preserving their ability to rebalance budgetary imbalances in trade flows through the mechanism of floating exchange rates. The aim of this study is to present the up-to-date perspective on evaluation of the factors influencing the exchange rates of the global reserve currencies that are also the basis of the predominant volume of transactions on the global currency markets.

  CUSTOMER RESPONSE PREDICTIVE ANALYSIS USING UPLIFT MODELLING

  Traditional customer response models are based on the understanding that marketing campaign effectiveness could be measured by predicting response probabilities of each customer. Such approach seems to be very reasonable and in most cases it gives better results than random targeting. A fundamental problem of response modelling is that it does not ... Traditional customer response models are based on the understanding that marketing campaign effectiveness could be measured by predicting response probabilities of each customer. Such approach seems to be very reasonable and in most cases it gives better results than random targeting. A fundamental problem of response modelling is that it does not separate the impact of a campaign from other stimuli and spontaneous responses because response models predict the wrong thing. They model and predict response probabilities, not the change in those probabilities as a result of the given marketing intervention. Following the understanding that traditional response models do not give optimal marketing decisions, the goal of this study is to define, estimate and apply on a real data base uplift model for predicting the change in customer behaviour resulting from marketing action. The specific tasks relate to studying the opportunities of a relatively new and less familiar methodology for identifying hesitant and persuadable customers. The study illustrates the application of the direct approach for uplift modeling and demonstrates its significant advantages over targeting based on uplift models over traditional response models.

  APPROACHES AND MODELS FOR MEASURING AND MANAGING COMMERCIAL BANKS LIQUIDITY

  The problems related to liquidity management and maintaining optimal levels of liquid assets of banks have become very topical and have stirred the interest of both the regulatory bodies and researchers in the field of banking and the general public. The pertinence of these problems arises from the importance of banks for the economic development ... The problems related to liquidity management and maintaining optimal levels of liquid assets of banks have become very topical and have stirred the interest of both the regulatory bodies and researchers in the field of banking and the general public. The pertinence of these problems arises from the importance of banks for the economic development of the national economies on the one hand, and from the possibility for transformation of banking problems into sectoral, national and international financial crises, on the other. The integration and the high level of interdependence of the economies worldwide are the key factors for accumulation of covert negative effects, which may trigger crises under certain conditions.
