The purpose of this article is to identify the main sources of cyclical fluctuations affecting the five Maghreb countries in a general analysis framework through the impact of the exchange rates and foreign direct investment. Besides, will consider in this study a set of variables taking into account the real monetary and fi ancial dimensions of the economies. Therefore, authors have adopted an approach in terms of the VECM Structural model and analyzed the robustness of the response functions. Indeed, the estimation results showed the existence of a regional dynamics where the respective sensitivity to change of the real exchange rate is the same. In addition, FDI and REER stimulate economic growth of the Maghreb economies in exchange for regime transmutations. In addition, the participation of FDI in the socio-economic development seems to be weak without the implementation of a policy of support and guidance aimed at reducing the catastrophic effects on the economy and reorienting its investments towards sectors with a high added value.

An approach is proposed for assessing the uneven use of information resources in the organization’s business processes. Formal representations of the organization’s business processes and security systems are presented, reflecting both business operations carried out in a certain sequence and information resources that ensure the implementation of the relevant business operations, the place of information resources in the general outline of business processes is indicated. The circuits of the security system business processes of and the business processes of the main object of modeling are considered, including both business processes for managing security and business processes for ensuring security management. The assessment of the non-uniform use of information resources in a business process scheme is based on the consistent construction of an information resource incidence matrix for individual business operations, a frequency relationship matrix reflecting the sharing of information resources, and a matrix of derivatives in a discrete formulation. The proposed approach is demonstrated on a conditional example containing both the notional costs of information resources and weighting factors of the importance of business operations that reflect their criticality in the general contour of business processes. Estimates obtained as a result of applying the approach make it possible to group information resources, focusing on the frequency of their joint use in the business processes, which ultimately makes it possible to justify the choice of information resources for protection against threats from cyber intruders.

The inefficiency of the State-Owned Enterprise is a matter of concern to economists. Among the studies carried out, those based on the theory of corporate governance were found. However, most of these studies focus on comparing the public enterprise governance with that of the private one. Thus, this article departs from this comparison towards an analysis of the governance of public enterprises to understand its inefficiency by examining the case of the Tunisian Railway Company. Starting with the approach used by Lehmann et al. (2002), it uses the Data Envelopment Analysis to evaluate the effectiveness of a governance system. The governance scores obtained were used to explain the ef¬ficiency variables for each year in the sample using regression in temporal data. The analysis revealed significant problems in governance mechanisms related to the lack of information transparency, weaknesses in functions of the government shareholder, and, in particular, control system failures.

The current stage of land relations in the agrarian sector is characterized by significant development of lease relations. Today, these relationships are heavily influenced by competition for land tenure, leading to increased land payments. Considering this, as well as the prospects for the agricultural land market formation, the task was to assess the dependence of agricultural land rent on the intensity and economic efficiency of wheat, corn for grain, sunflower production. The research was carried out on the example of agricultural enterprises of Kharkiv region. Grouping, a graphical method was chosen as research methods. The subject of the study was also the rent dynamics for agricultural land in Kharkiv region and Iowa, the USA. The obtained results made it possible to establish the fact that the rent value depends on the total amount of expenses, and the expenses on the articles «wages», «depreciation». It is concluded that the reasons for this may be related to the investment of these enterprises in human capital and the fixed assets that make them lease on more favorable terms for share owners. No dependence was found between the rent value on the value of the yield and the financial result on the selected crops. At the same time, there is a clear tendency that with the increase in the value of the rent, there is an increase in the ratio of its value to the value of costs and income from the crop sector. It is concluded that this can lead to a decrease in investment opportunities for the enterprises with the highest level of lease payments for agricultural land.

The subject of this paper is empirical research on studies of exchange rates in Eastern European countries, such as Albania, Bulgaria, Bosnia and Herzegovina, Belarus, Czech Republic, Estonia, Croatia, Hungary, Latvia, Lithuania, Moldova, (North) Macedonia, Montenegro, Poland, Romania, Serbia, Slovakia, and Slovenia, in order verify the validity of theories that explain these changes. This research aims to explain the mixed evidence of the Balassa-Samuelson effect in Ukraine, taking into account the intentions of Ukraine to become a member of the European Union. Unlike previous works, the attention is shifted to a review of empirical evidence and the identification of main factors that limit the ability to verify the theory. The main conclusion is that all the currencies studied underwent substantial real appreciations during the study period. Thus, it can be concluded that an adequate monetary policy in countries under study is very important, given that local exchange markets are not sustainable enough and the volatility of exchange operations is higher than in countries with developed economies. However, the Balassa-Samuelson Hypothesis (BSH) can explain the impact of the real exchange rate due to changes in productivity in countries in transition.
