From Growth to Green
Due to severe climate challenges, global economies are transitioning to green energy, specifically, the solar thermal and wind energy to attain the COP28 targets and sustainable development goals (SDGs). To fulfill energy demand, countries are investing in these sources, yet their role in the global greenhouse gas (GHG) emissions is not clearly examined. The objective of this research is to examine the linear and nonlinear implications of solar t…
Do Land Resources, Agriculture Exports, and Agriculture Growth Induce Agriculture‐Related Greenhouse Gas Emissions
Globally, economies are highly concerned about the balance between climatic issues and attaining agricultural sustainability. However, empirical evidence regarding the nexus of agricultural sustainability, emissions, land use, and agricultural trade is scarce and requires appropriate policy‐level attention. The current study examines the influence of land‐use resources, agricultural exports, and foreign direct investment on agriculture‐related gr…
Impact of ESG rating divergence on corporate resilience
The dilemma of water, food, and greener energy nexus
In the contemporary world, achieving sustainable food production has become an urgent task for the international community and policymakers due to the rapidly growing social challenges of mankind. Sustainable food production practices aid countries in adapting to the challenges posed by climate change, thereby ensuring a better and more sustainable future for all. This study examines the impact of land use, energy efficiency (ENE), water producti…
Natural resources, food, energy and water
There is a notable scarcity of literature addressing the complex affiliation amidst natural resources, water productivity (WPROD), and the food production index (FPI). Existing research focuses on emerging and developing countries, primarily centering on the initial objectives of sustainable development. To bridge this literature gap, our research delves into the nexus of WPROD, FPI, and total land resources (TLRS). Additionally, the study explor…

Trust crisis in the financial sector and macroeconomic stability
Although the growing body of literature that recognises a destabilising role of the trust crisis in the macroeconomic stability, the understanding of mediational pathways remains limited. The current paper fills the gap by contributing to the existing literature by examining closely the mediating effect of the trust crisis in the financial sector on the indicators of macroeconomic stability due to the anticipated impact of the financial intermedi…
Causality of the relationship between wheat prices and economic conditions - an evidence for sustainable development
Changes that are occurring in economic activities over time are the subject of interest for many economists. One of the primary goals of economics is to understand their causes. Nowadays, there is a prevailing view that economy is subject to certain fluctuations, that is disturbances in the long-term growth, which develop at irregular intervals and which are of an irregular force, and cause changes in the functioning of the entire economy Fluctua…
Modelling European sovereign default probabilities with copulas
The goal of this article is to investigate a dependence among sovereign countries’ risk of default. The analysis was based on data for 42 European countries during the period 1994–2013. Three models were used to calculate default probabilities: Li’s based on transition matrix and prudent unconditional and conditional on previous defaults estimation technique for low default portfolios. The relationship was analysed through the use of different ty…
Evaluation of the effectiveness of investment fund deposits in Poland in a time of crisis
The present publication constitutes an attempt at evaluation of the effectiveness of investment fund deposits at Polish market in the years 2000-2015. In the paper, a distinction is made between two subperiods, namely, the years before the economic crisis, meaning 2000-2006, and the years of the socalled crisis, meaning 2007-2015. This approach had the goal mainly of evaluating the effectiveness of investment fund deposits in the years of economi…
Stability analysis of the banking system
The present work deals with the stability analysis of a banking system with the structure in the form of Apollonian graph based on such characteristics of the banking system as the modularity and inhomogeneous distribution of banks by degree, on the basis of the extended mean-field Nier model (a static approach based on a simplified balance sheet of assets and liabilities of the bank) which was used to analyze the extent of the process of bankrup…
Small and medium enterprises in the context of regional development and innovations
The current state of economic development and innovations' support often brings small and medium enterprises (SMEs) at the forefront of government fiscal policy. Various policy measures targeted at SMEs' support and development necessarily include measures on promotion of innovations within small business. However, despite substantial efforts undertaken by the authorities to increased financial injections into this area, development of innovation…
In search of insolvency among European countries
The global financial crisis has proven to be one of the worst and most-demanding events ever. According to common understanding, it is highly unlikely for a country to go bankrupt. However, we have seen a number of countries on the verge of bankruptcy, as well as many which have officially gone bankrupt. It is probable that many more will do so in the future. This knowledge has led us to the question: how probable is it that a sovereign might suf…
Influence of double seasonality on economic forecasts on the example of energy demand
Th e article deals with the issues of forecasting one of the most important elements of modern economies, which is electricity. Th e size of its production must be properly predicted and it should be technically possible and profi table from the economic point of view. Th e most frequently used forecasting models in literature are ARIMA and exponential smoothing. However, these models have a major disadvantage as they do not allow forecasting the…
Factors of Efficiency of Open Investment Funds in 1997-2015
The deepening economic and financial crisis in 2011 highlighted a number of negative phenomena arising from the current state of development of world's financial markets. The problems of the Euro area, the specter of its decay, and continuous rating downgrades of EU Member States undermined the confidence in the markets. This was also reflected on the example of the market of investment funds. A key element becomes a rapid identification of inves…
Qualifications of managers vs. effectiveness of investment funds in Poland
Purpose -The main objective of this paper is to assess the impact of qualifications of the management staff on the effectiveness of open investment funds.

Findings -Investment funds operating in the Polish market divided into four groups of funds have been subject to…
Compatibility of market risk measures
An important element of everyday financial decisions is to assess the scale of the risk of investing in various financial products. Knowledge on the degree of risk of the activities undertaken in this field allows a certain predictability about the negative effects that may occur. This is of great importance in the context of aversion to risk, and thus a better allocation of resources. A multitude of market risk measures is substantial and in add…
