This article presents Professor Joanicjusz Nazarko’s outstanding achievements in research, scientific cooperation, teaching and organizational work, in celebration of the 45^th jubilee of his scientific work. Over the years, Professor Nazarko has contributed significantly to the development of technical and social sciences in Poland. He authored more than 300 publications, which constitutes a substantial knowledge base on its own. Using bibliometric and statistical methods and techniques, we present an overview of Professor’s most important scientific achievements and major works. We also highlight his efforts to establish a national and international network for scientific cooperation. Lastly, we present his didactic successes. This jubilee serves as the opportunity to recognize and honour Professor Joanicjusz Nazarko’s significant contribution to the development of science in Poland.

Unveiling the role of industries for European financial stability. Insights from the energy sector

Iulia Lupu — 2024-05-24

Extensive analysis of intertwinement with other industries caused the energy sector to gain momentum in the recent economic literature. This paper aims to create an indicator that captures the impact of financial stability for energy companies on all other industrial groups. To this end, we use daily data from 2007 until the end of 2021 to compute financial stability metrics for all European companies from the STOXX 600 index. The main contribution of our study is to harness the neural network forecasting power to predict extreme levels of this impact. We motivate this choice with evidence from the literature that documents the improved performance of these methods in predicting crises. Our methodological approach also employs an outlier detection algorithm based on copula (COPOD) to identify situations when the energy sector substantially impacts other industries and develop a framework to predict out-of-sample situations. We found evidence that the Deep Renewal model has superior forecasting accuracy to the standard Croston model. The main conclusion is that the design of this methodological framework allows authorities to monitor the impact of shocks produced by the energy sector on financial stability at the European level and undertake strategic management actions.

Does online media attention improve China’s green fund performance?

Yaping Xiao — 2024-05-27

This study investigates the relationship between online media attention and the performance of China’s green funds. The results show that increased media attention can boost the performance of green funds in the short term, however, this effect is short-lived. The mechanism of short-term positive effects may be due to increased media attention leading to larger purchases, which may undermine funds’ long-term performance. In particular, online media attention has a greater impact on larger and older funds. Moreover, it indicates that media attention reduces the returns of individual investor-dominated funds, but has little effect on institutional investor-dominated funds.

The relationship between the circular economy and business performance: a systematic literature review

Marta Nosková — 2024-06-17

The circular economy represents an effective way to address limited resources and mitigate the impact of human activity on the planet. To summarize the possible effect of circular economy implementation on business performance and its possible measurement, a systematic literature review on a final sample of 28 papers was conducted. The main findings reveal that the circular economy can help to improve business performance and that numerous indicators could be used to measure it, especially the balanced scorecard approach, which seems suitable for such classification (however, more research on this topic is needed). Additionally, it was revealed that the circular economy concept itself has no clear and generally used definition, which complicates the summarizing of the revealed indicators. To simplify future research, we proposed a research framework based on this systematic literature review and emphasized the research gaps.
