In recent years, the European Union (EU) dairy sector has experienced considerable changes, triggering heavily fluctuating milk prices and a crash in milk prices in 2015/2016. These changes were forcing dairy farmers to respond by reconsidering their strategy. Since there is a lack of insight into how farmers were adjusting their strategies to the new circumstances, this study aimed to fill the gap by conducting a survey on farmers’ development plans in three Central and Eastern European countries (Poland, Lithuania and Slovenia) with different farming systems and one Western European country with a well-developed dairy sector (the Netherlands) before (2010 and 2013) and one year after the EU milk quota was abolished (2016).

The subject of the research is the condition of cross-country tax competition and its influence on the tax system compatibility. The urgency of the research is determined by the prospects of tax government risks mitigation tools introduction in response to the necessity to reduce budget deficit on the whole and to the increasing risks of competitiveness lowering as a result of growing tax bases mobility in particular.

This paper aims at developing the theoretical framework for linking the CSR of energy utilities with sustainable energy development achievements and at applying this framework in selected countries. The main issues of CSR relevant to the energy sector are discussed, and a comparative analysis of CSR reports of energy utilities and sustainable energy development trends in the Baltic States (Lithuania, Latvia, and Estonia) is performed based on the developed framework.

The identification of “industrial soot” or “vehicle exhaust” pollution facilitates developing proper measures for the mitigation of regional air pollution. In order to identify the pollution types at a regional level, this paper applies the Luenberger productivity indicator to decompose air pollutant emissions performance. Furthermore, we simultaneously consider pollution rates and the productivity change.

The purpose of this article is to propose the integrated index of Public Governance efficiency based on the Fishburne’s method, considering the impact’s power and direction of the different sub-indexes (Worldwide Government Indicators) on macroeconomic stability and eliminating the issue of multicollinearity.

This paper seeks to propose a network data envelopment analysis (DEA) framework for analysis of heterogeneous systems. The paper introduces the dummy connector so that every network structure can be transformed into the sun network structure. In his case, the dummy connector allows for heterogeneity of the decision making units (DMUs) in terms of their inner structure.

An analysis of the scientific literature has revealed that companies in advanced countries have mixed capital structures, whereas companies in less advanced countries mostly depend on bank credits and loans. The reason for dependence on bank funding lies in the fact that corporate bonds are profitable only to large companies with a high credit rating, while small and medium companies - as well as large companies with lower credit ratings - find bank loans to be a more attractive method of external financing.

he picture fuzzy set (PFS) is a powerful tool to collect and handle large amounts of uncertain assess information in a new light. In this study, we explore some distance measures for the PFSs and propose Picture fuzzy ordered weighted distance measure and Picture fuzzy hybrid weighted distance measure. Some of their properties are also mathematically explored. Moreover, we introduce a model for the aforesaid distance measures to solve multiple attribute group decision making (MAGDM) method in an updated way.

The main objective of this study is to analyze and compare greenhouse gas emission profiles, dynamics thereof, and the climate change mitigation efforts of the major players in the global climate change arena, namely the G7 and BRICS countries that are accounting for more than 60% of the world greenhouse gas emissions as in 2017. Given that the energy sector is the major source of the greenhouse emissions in these countries, the framework of sustainable energy development indicators was applied to the comparative analysis.

China has undergone a series of agricultural policy reforms since 1978. The measurement of the productivity gains and identification of the underlying drivers thereof are important facets of policy analysis. The commonly used Total Factor Productivity (TFP) measures often lack such desirable properties as completeness or independence of the direction of the optimization (orientation).
