Opis:
The study was conducted to assess and substantiate the key systemic problems of the national engineering of different countries in the context of economic globalization. To achieve this goal, the study used the author’s method to assess the dependence of mechanical engineering in Ukraine, Poland and Germany on imports of intermediate goods. According to the results, it was determined that in the periods of increasing economic globalization of mechanical engineering in Ukraine, Poland and Germany has undergone systemic destructive changes and is in a threatening state, from the standpoint of economic security. In particular, in Ukrainian and Polish mechanical engineering, the dependence on imports of high-tech intermediate goods is excessively high. In contrast, German engineering, unlike Ukraine’s and Poland’s, is less dependent on imports of high-tech products, but requires much more resource-intensive intermediate goods. It is analytically substantiated that the identified problems with the import dependence of mechanical engineering in Ukraine, Poland and Germany are the result of irrational, one-sided perception of economic globalization by the main economic entities of these countries.

Opis:
The economy of Slovakia experienced a turning point in the 1st half of 2008 and entered a phase of decline. The negative impacts of the global economic crisis became evident in the 2nd half of 2008 and led into a recession in the 1st quarter of 2009. The composite leading indicator was originally intended for forecasting of business cycle turning points between the decline and growth phases. The aim of this paper is to transform the qualitative information from composite leading indicator into quantitative forecast and verify whether the beginning of recession in Slovakia could have been identified in advance. The ARIMAX and error correction models are used for the composite reference series and GDP forecasts respectively. The final result shows that the composite leading indicator is useful not only for identifying turning points, but also for the prediction of recession phase.

Opis:
We propose a method of constructing multisector-multiregion input-output tables, based on the standard multisector tables and the tools of spatial econometrics. Voivodship-level (NUTS-2) and subregion-level data (NUTS-3) on sectoral value added is used to fit a spatial model, based on a modification of the Durbin model. The structural coefficients are calibrated, based on I-O multipliers, while the spatial weight matrices are estimated as parsimoniously parametrised functions of physical distance and limited supply in certain regions. We incorporate additional restrictions to derive proportions in which every cross-sectoral flow should be interpolated into cross-regional flow matrix. All calculations are based on publicly available data. The method is illustrated with an example of regional economic impact assessment for a generic construction company located in Eastern Poland.

NEO-LIBERAL MARKET MODEL

IDEOLOGY
MARKET VS STATE
LESZEK BALCEROWICZ
Opis:
The article focuses on social and psychological aspects of criticisms of neo-liberal market model, mostly referring to the views of Leszek Balcerowicz. It points out that neo-liberal approach is based on a limited concept of freedom and its meaning in human life, underestimating the connection between freedom and ideological beliefs of people. Moreover, neo-liberalism does not take into account the fact that in conditions of economic freedom the interference between the level of individual effort (productivity) and access to goods (rewards) is weakened and may lead to self-destruction of the market system. But the shortcomings of the market mechanisms are not an argument for their replacement with state control over economy. They rather should instigate problem solving efforts.

Opis:
Many studies on middle income trap draw attention to the product trap that can be expressed as the fact that countries are stuck in the production and export of unsophisticated products. In this sense, it is stated that the role of a country in the production and export of sophisticated goods is one of the determinant factors to increase the level of income. In the literature, the concept of economic complexity, which is expressed as gaining competitiveness of complex products in terms of production and export, is noteworthy in recent years. In this framework, relationship between the per capita GDP and the economic complexity is examined with regression analysis in this study for selected countries with high-level of income. In the analysis, in which random coefficient panel regression model is applied, a significant relationship was found between the two variables for Austria, Finland, Hong Kong, Japan, Norway, Singapore and Sweden.

Opis:
Aiming at the problems of low accuracy, low efficiency and low stability of traditional methods and recent developments in advanced technology incite the industries to be in sync with modern technology. With respect to various available techniques, this paper designs a fuzzy comprehensive evaluation model of the manufacturing industry for transferring risk based on economic big-data analytics. The big-data analysis method is utilized to obtain the data source of fuzzy evaluation of the manufacturing industry to transfer risk using data as the basis of risk evaluation. Based on the risk factors, the proposed model establishes the risk index system of the manufacturing industry and uses the expert evaluation method to design the scoring method of the evaluation index system. To ensure the accuracy of the evaluation results, the manufacturing industry’s fuzzy comprehensive model is established using the entropy weight method, and the expert evaluation results are modified accordingly. The experimental results show that the highest efficiency of the proposed method is 96%, the highest accuracy of the evaluation result is 75%. The evaluation result’s stability is higher than the other existing methods, which fully verifies the effectiveness and can provide a reliable theoretical basis for enterprise risk evaluation research.

Opis:
The competence-based learning-teaching process is a significant approach to the didactical process organization. In this paper the mathematical model of the competence-based learning-teaching process is proposed. The model integrates three models: a knowledge representation model (based on the ontological approach), a motivation model (as a behavioral-incentive model) and a servicing model (in a form of the queuing model). The proposed integrated model allows to control the learning-teaching process on different levels of management. The learning-teaching process can be interpreted as competence-based due to Open and Distance Learning (ODL) philosophy. We assume that the competence is a result of fundamental, procedural and project knowledge acquisition in accordance to the incoming European Qualification Framework.
