Author(s): Rosen Nikolaev,Tanka Milkova / Language(s): Bulgarian / Issue: 1/2012

The present work is devoted to the study of some possibilities for determining optimal variants for the attachment of consumers to suppliers in the economic systems of supply of raw materials, prime materials, production, services, etc. There are presented several static models for attaching consumers to suppliers, and there are also offered some modifications in order to adapt those to real, practical situations. There are designed a general static model for attaching consumers to suppliers and a model accounting for the carrying capacity of available vehicles, as are done approbations of these models. There are suggested dynamic models for attaching consumers to suppliers, based on: known intensities of production and consumption for the subperiods of the entire planned period; fixed determined demand and the possibility for attachment to a single supplier; equal volume of delivery for all suppliers.

The article reviews contemporary concepts about corporate inventory planning and management from a systematic perspective. It elucidates the nature and the underlying principles of the technology of corporate inventory management. These are followed by a detailed description of deterministic and stochastic quantitative models which are most frequently applied in the sphere of financial theory and practice. The article finally arrives at the conclusion that deterministic models are easy to apply, yet their major disadvantage is that they could only be applied for one type of inventory. Stochastic models, on the other hand, are much more complex in nature, yet they could be applied to any type of corporate inventory, which renders them more flexible and applicable.

Модели на образовен менаџмент

Author(s): Vasil Popovski / Language(s): Macedonian / Issue: 3/2009

This article gives short description of the different aspects and models of educational management. Educational management is a field of study and practice concerned with the operation of educational organizations. Many authors argued about the objectives of the educational management as a specific field of management process. According to the world experience theory and practice of the educational management can define six models: formal, collegial, political, subjective, ambiguity and cultural.The six management models discussed in this chapter represent different ways of looking at educational institutions. Each screen offers valuable insights into the nature of management in education but none provides a complete picture. The six approaches are all valid analyses but their relevance varies according to the context. Each event, situation or problem may be understood by using one or more of these models but no organization can be explained by using only a single approach. There is no single perspective capable of presenting a total framework for understanding of educational institutions.The six models differ along crucial dimensions but taken together they do provide a comprehensive picture of the nature of management in educational institutions. The six models present different approaches to the management of education and the syntheses indicate a few of the possible relationships between them. However, the ultimate test of theory is whether it improves practice.

The problem of efficient forecasting for the agriculture is connected with the imperfect methodological and instrumental substantiation of its development parameters. Systematisation of the western models of partial equilibrium has proved that projecting the international experience of forecasts’ substantiating on the Russian agrarian economy reduces the forecasts’quality and distorts the predicted situation for the food market. That happens because such models are based on different criteria and objectives for the farmers’ development. We developed modern models for substantiating the parameters of agricultural development and scenario forecasts. The research objectives are connected with generalisation, systematisation and critical assessment of the instruments used for agricultural forecasting in Russian and foreign practice. We focused on shaping the substantially different instruments of scenario forecasting and model calculations. We applied the method of econometric diagnostics, the partial equilibrium model, and Cobb-Douglas production function. We used the data of financial reporting of 250 agricultural manufacturers from Penza oblast for the period from 2006 to 2016 as the study’s information basis. Further,we developed a set of scenario forecasting models, which are significantly different. These models have the functional capabilities of assessing the prospects of the agricultural development taking into account the attained production level, agrarian market’s environment, state measures, key factors of the agricultural products’ output. Based on the assessment of these models and diagnosed results, we concluded that the existing trends of forward movement in terms of the agricultural production’s supply are insufficient, as they do not fully satisfy the demand. We revealed the elasticity and disproportionality of the relationships between the growth rates of supply and demand in the agro-food market. Moreover, we collected the data on the qualitative dependence of the activities’ results in total on the factors of agricultural production and the state support measures. These factors show the threshold of expediency for additional investments of land, labour, capital and subsidies. This information will allow improving the economic mechanism of forecasting the agricultural strategic development. Additionally, it will contribute to strengthening the focus on the outcome of the manufacturers’ activities and increasing the level of achievement of the anticipated indicators

The main aim of this paper is to investigate the debt capacity of the Bulgarian municipalities as an area of the municipality finance, requiring decision-making based on modern methodology. Those decisions are exceeding the traditional one year planning horizon. With the introduction of the multyyear models for budgeting and analyses of the capacity of municipalities’ debt issue it is allowed to consider with the unique characteristics of the municipality debt-issuer. Such approach enlarges the capabilities in front of the municipal financial management. Therefore it is confirmed that Bulgarian municipalities are able to maximize the effects of absorption of operating programs funds through development of the capacity of co-finance, including debt issue. Such policy could be introduced in borders, guarantying acceptable debt services under the conditions of various, multiyear scenarios for the development of the local community under the condition of fiscal decentralization.

Моделиране кривата на spot лихвените про¬цен¬ти в българските условия

Author(s): Alexander Ganchev / Language(s): Bulgarian / Issue: 1/2008

Object of study in the article is the curve of spot interest rates taken at the market of government securities in Bulgaria for the period of time - January 2006 – December 2007. The quantitative models for modeling the yield curve are subject of research and especially the spot interest rates’ models, including the model of Vasicek, the model of Nelson and Siegel, the model of Svensson, the model of ElKaroui, Cherif, Dicoum and Savidan and the model of Martellini and Priaulet. The article reaches the conclusion that most ineffectively the curve of spot interest rates is drawn up by means of Nelson and Siegel’s model. The main results from the carried out empiric tests show that the Martellini and Priaulet model distinguishes with its high stability, satisfactory accuracy and high ability to model correctly the bond prices. This makes it the most suitable for modeling the spot interest rate curve at the market of government securities in Bulgaria.

Author(s): Elena Ralinska / Language(s): Bulgarian / Issue: 1/2019

We propose an upgrade, adaptation and implementation of a factor model of historical financial analysis, forecasting and valuation of the banking institution through the method of discounted cash flows based on publicly accessible data, which can be applied in the practice. We research the adequacy and plausibility of the approach, its benefits and drawbacks, as we test it on Unicredit Bulbank Ltd, and we apply a comparative valuation approach and accounting reference values of control of the obtained results. The research objective is to upgrade and calibrate the model by introducing restrictive conditions for forecasting in compliance with the existing regulatory framework and the observations of the practice. For this purpose, we have also introduced a feasible parametrization and we have brought forth relevant recommendations for forecasting the activity of banking financial institutions.

The article describes an attempt to use, through microeconomic models, factors and causes determining investor’s behaviour of the participants in the mass privatisation. In particular the object of the research is the demand of stocks issued by the offered for privatisation enterprises. The survey includes all enterprises listed on the three auctions of the first round of mass privatisation, carried out in 1996. The results of the estimated model of the logistic regression show that the investors have made their decisions for buying stocks from enterprises guided by the classical investment and finance theory. The data shows that enterprises with positive profitability, low immobilization of property, high turnover of the capital, lower debts and bigger share of stocks listed on the auction, have higher probability for buying out. The investor’s attention has been directed to enterprises in light industry and in services.

Author(s): Sardor Sadykov / Language(s): English / Issue: 2/2018

The paper presents the results of an empirical evaluation of various types of new Keynesian Phillips curves for modeling inflation dynamics in Uzbekistan in particular, was rated "standard" form of the new Keynesian Phillips curve, its modification for a small open economy, as well as a hybrid form of this curve, which, along with the rational (being proactive (forward-looking)) inflation expectations also considers adaptive (nasal spray (backward-looking)) inflation expectations. According to the results of the evaluation of the new Keynesian curves of Phillips, the degree of influence of forward-looking inflation expectations and the deviation of the average marginal cost of production from the equilibrium level on inflation in Uzbekistan were determined, additional macroeconomic factors of inflation were identified, and the degree of relevance of the inflation expectations in relation to inflation and its comparison with the degree of influence on inflation of forward-looking inflation expectations was calculated. The results of the study can be used to improve the efficiency of the development and implementation of monetary policy in Uzbekistan within the framework of the inflation targeting regime. Also, this study can serve as a basis for further modeling of economic processes in the framework of the approach of the new Keynesian theory in Kazakhstan and in other countries with economies in transition.
