This paper deals with the application of mathematical methods to the inventory of blood units in a regional supply system.A complex simulation model was designed and implemented in the discrete simulation language SIMSCRIPT to investigate alternative inventory and distribution policies for blood units by means of defined objective criteria. These procedures include a method for inventory forecasting and blood donor call-up and a heuristic allocation model for blood units.Empirical data was collected from the Berlin Blood Donor Service for model construction and validation.The simulation results suggest that the inventory procedures presented may lead to a considerable cost reduction in a regional blood banking system.A specific statistical testing procedure was employed to justify the simulation results statistically. In the final section it is suggested that the inventory methods described in this paper can be implemented within a computer information system providing the blood bank management with decision aids.

The dynamic nexus between money supply, fiscal deficit, inflation, output and exchange rate management has recently generated much debate in economic literature in Nigeria. To contribute to this debate, this paper uses the co-integration and error correction framework of analysis and also conducts policy simulation experiments to investigate how monetary variables interact with aggregate supply, demand and prices in order to aid stabilization policies. The results show that monetary variables and government finance are linked through government’s net indebtedness to the banking system. The simulation results show that a 20 per cent monetary squeeze would reduce the inflation rate faster than if the reduction in money supply were 10 per cent. This reduction in money supply would also lead to a reduction in output, employment and government expenditure, which may hurt the domestic economy. The paper thus concludes that there is a trade-off between higher GDP growth and inflation in Nigeria.

This paper attempts, first by a simple numerical example and then by more rigorous mathematical methods, to investigate the important relationships between supply, demand, distribution, and price in the housing market. A theory of house price is linked to the derivation of home-workplace interaction models. A function for evaluating different distributions is derived and a possible linear programming approach to a marginal stock allocation model is discussed.

Introduction. The article deals with the main problems of adaptation of the NBU monetary and credit regulation to the inflation-targeting mode. The main reasons for the low efficiency of the introduction of world experience in the field of monetary policy to domestic realities are considered. The methodical recommendations for increasing the efficiency of monetary regulation, optimizing the monetary mode of inflation targeting and implementing the monetary rule in the practice of realization of monetary policy of the NBU are developed. Purpose. The article aims to study the world experience in the field of adapting monetary and credit regulation to the monetary mode of inflation targeting on the example of New Zealand and to develop the theoretical and practical conclusions for Ukraine. Method (methodology). The following general scientific methods have been used in this research: method of synthesis and generalization (to substantiate the basic problems of monetary regulation in the context of realization of the monetary regime of inflation targeting in Ukraine); methods of analysis and comparison (to study the experience of New Zealand in the field of the formation of the monetary mode of inflationary regulation); statistical and mathematical methods (to develop monetary rule in Ukraine). Results. The main problems of low efficiency of monetary regulation in Ukraine that are related to the neglect of national interests, imbalances in the development of the national economy, inappropriate structure of exports and imports, negative business environment, and conditions for the absorption of monetary impulses have been identified. The experience of New Zealand in the field of the formation of the monetary mode of inflation targeting has been researched. It has been made the conclusion concerning a long transitional period during which, at the level of inflationary purposes, de facto, as intermediate monetary policy objectives, the exchange rate and liquidity of the banking system are used. The monetary rule for Ukraine has been developed. The methodical recommendations for increasing the effectiveness of the monetary and credit regulation of the NBU within the framework of flexible inflation targeting have been worked out.

Ensuring efficiency improvement of banks is a priority task for Ukrainian banking system at the stage of creating the developed financial sector of economy. The study of a bank performance, which takes into account a risk factor of banking business, is particularly relevant due to the need to ensure competitiveness and stability of both individual banks and the banking system as a whole.The aim of this article is to develop a methodology for integral evaluation of the Ukrainian banks according to the efficiency and risk criteria. Ratio analysis, mathematical methods, comparison and grouping, synthesis, table, matrix and graphic methods make the methodological basis of the research. The object of the analysis is the activities of Ukrainian banks.The study was conducted to elaborate a method for risk-oriented integral estimation of efficiency of the banks functioning. One can state that high efficiency and low risk of a bank’s work do not depend on the volume of assets, equity and profit for Ukrainian banks.The analysis made it possible to evaluate the strategies for the development of Ukrainian banks. The vast majority of Ukrainian banks have chosen a moderate strategy in the context of balancing the efficiency and riskiness of their activities. According to the results of factor analysis using Raiffeisen Bank Aval as an example, the main factors of gross profit growth were determined as increase in bank profitability and expansion of its active operations volume relative to its own capital.

AbstractIn this paper, we suggest new cointegration tests that can become more powerful in the presence of non-normal errors. Non-normal errors will not pose a problem in usual cointegration tests even when they are ignored. However, we show that they can become useful sources to improve the power of the tests when we use the “residual augmented least squares” (RALS) procedure to make use of nonlinear moment conditions driven by non-normal errors. The suggested testing procedure is easy to implement and it does not require any non-linear estimation techniques. We can exploit the information on the non-normal error distribution that is already available but ignored in the usual cointegration tests. Our simulation results show significant power gains over existing cointegration tests in the presence of non-normal errors.
