Opis:
This article presents the concept of sustainable development that might be defined as a tool leading to not only a favorable economic growth, but also the elimination of disproportions within a society in the long run. In this context, the social and economic inclusion of all existing social groups, as well as maintaining safety in terms of environmental protection seem to be important. Such practices, known as an inclusive growth, are frequently practiced by public and private institutions. In this publication, the special focus is put on the importance of finance in the concept of sustainable development. The authors try to prove the hypothesis that it is the financial system (financial institutions, financial markets and avoidable regulations) that plays a main role in the realization of goals of sustainable development.

Opis:
In recent years, the banking sector has started to prioritize sustainable development, recognizing the growing benefits of sustainable investment. However, they e ncounter many obstacles on the road, among others, the time horizon, waiting for regulatory proposals, and a lack of understanding of the potential effects of climate change. To strengthen its sustainability policy, the ESMA decided to harmonize transparency rules that should have a significant impact on the entire banking sector. The purpose of the article is to organize basic definitions related to the sustainable development policy, to show the role of finance in the whole process, to present important changes in the regulation, and to approximate current changes in the field of sustainable development in the banking sector.

Opis:
Theoretical background: The green bonds market is growing rapidly and serving as a source of financing for energy transition, social impact investments, green economy transition, and climate change mitigation projects. It is also an interesting alternative investment opportunity for increasingly conscious investors. Researchers are studying the green bonds market from several perspectives, among others they search for premiums for being green – greenium; they analyse the interconnectedness of conventional and green bonds markets in the search for portfolio diversification opportunities and they consider the usefulness of green bonds in the times of market crisis or turbulences as hedging strategies instruments. Purpose of the article: The purpose of this article is to verify the nature and direction of the relationship between green bonds markets and conventional bonds markets, as well as its permanence during market shocks. Research methods: Our analysis is based on rates of returns from green bonds indices and their respective counterparts in the period between January 2015 and April 2021, we used conditional volatility and dynamic conditional correlation with multivariate Gaussian and T-Student distributions. Main findings: We found similar patterns of behaviour between green and conventional bonds markets, but the green bonds market is riskier than the non-green one and the risk relationship of both bond markets is changing. Our research results lead to the conclusion that investors are more prone to flee from the green bond market and stay in the conventional bond market in times of market shocks such as the outburst of COVID-19 pandemic.

Opis:
The article discusses the potential impact of sustainable finance initiatives on financial stability. A careful literature review on the subject of sustainable development and stability of the financial sector is performed in order to identify potential gaps in policies and regulations. Existing considerations around the impact of sustainable development efforts focus exclusively on the consequences of climate change for the portfolio of assets held by the financial sector, whereas the author examines the growing market for sustainable financial instruments as a potential threat. The results indicate that sustainability features of new financial instruments are not methodically evaluated in the context of their credibility and may therefore suffer from sudden loss of value that is not accounted for under the existing supervisory mechanisms. Inconsistent definitions and no single perception of sustainability further enhance the risk for investors and issuers and that risk needs to be accounted for under the mechanisms safeguarding financial stability.

Aim. The aim of this article was to analyse relevant literature as well as financial services sector professionals’ expectations on future sustainability competence needs among vocational business graduates as part of an ideation process to design an open online course within the project “Sustainability in Finance – SuFi” (2020-2022). Methods. The online mixed-method survey was elaborated using Google Forms and Webropol and distributed via email among finance services industry professionals in Finland, Latvia, Estonia, and Aland Islands. In total, 221 responses were obtained. The qualitative and quantitative data analysis was performed using NVivo and SPSS. Results. Qualitative data analysis revealed that the conceptual knowledge of business graduates was the most frequently mentioned category, followed by procedural knowledge. Among the key competencies in sustainability, the most necessary was intra-personal competence, followed by inter-personal competence. Quantitative data analysis revealed that the top three sustainable finance competencies in demand within respondents’ organisations were: to understand relevant driving sustainable forces, to think and operate with a long-term perspective, and to communicate sustainable financial information in a meaningful way. Conclusion. In the Baltic Region’s finance sector, there is a need for a more holistic view for understanding the market as part of society as a whole and also the meaning of understanding long-term horizons. The competencies that financial services sector professionals found important for vocational business graduates in future work were used as an input for elaborating vocational business education study courses.

The article reviews potential channels of impact of climate change on monetary policy and central bank operations. The issue of climate change is increasingly becoming the focus of central banks. The article begins with the discussion on the consistency of central banks’ mandates and a potential role of central banks in climate policy. The second section concentrates on risks climate change poses to the effectiveness of central bank action and operations. Then it reviews options for the central bank to engage in the fight against climate change. Finally, the determinants of this engagement are presented. The author argues that some intellectual progress has been made in central banks in terms of adjusting their operating framework, but many gaps still exist and much more analytical work is needed.

Opis:
Research background: Achieving a jointly stable and inclusive financial system represents an important pillar of the call for action among Sustainable Development Goals. Considerable attention from previous research has been given to traditional financial inclusion (FI) and its implications on financial stability and overall development, but the findings are mixed. Furthermore, there is limited evidence related to the implications of digital financial inclusion on banking system stability. Therefore, the present study tends to address two main research questions, as follows: Can traditional financial inclusion protect banking stability? Can digital finance inclusion become a new driving force to promote banking stability? Purpose of the article: The paper aims to assess the influence of both traditional and digital financial inclusiveness on banking stability, using quantile regression, across a panel of 81 countries. We also examine the potential transmission channels through which financial inclusiveness influences banking stability. Methods: We construct three different financial inclusion indices, which capture the degree of access and usage of financial services, based on a three-stage Principal Component Analysis. Next, based on quantile analysis, we test the role of these financial inclusion indices in shaping banking stability. Findings & value added: We provide international evidence on the non-linear relationship between traditional and digital FI and banking stability, respectively. Our empirical findings suggest that FI indices are negatively related to banking stability until a certain threshold, after which, increases in financial inclusiveness have a positive effect on banking stability. The magnitude of the impact is more sizeable for low-range quantiles, meaning that the effect of digital inclusiveness is more pronounced in countries with excessive risk-taking tendencies. We find support for operational efficiency transmission channels and uncover new evidence on the association between digital FI and banking stability.

W opracowaniu zwrócono uwagę na konieczność postrzegania finansów zrównoważonych, jako kategorii ewoluującej pod wpływem oddziaływania triady czynników środowiskowych, społecznych i ekonomicznych, kształtujących współczesne zjawiska i stosunki finansowe. Dokonano także próby wskazania i uporządkowania priorytetów, którymi powinna kierować się współczesna nauka finansów oraz wskazano na pożądany udział poszczególnych czynników w kształtowaniu decyzji finansowych podmiotów gospodarki narodowej.
This article attempts to make a redefinition of conceptual categories, which are “financial balance” and “sustainable finance” in response to changes taking place in contemporary surroundings. The study highlighted the necessity of considering the sustainable finance, as a category evolving under the influence of the triad of environmental, social and economic factors impacting on the contemporary phenomena and financial relations. There have also been attempts to identify and clarify priorities, which should be guided by the modern science of finance and pointed out the expected share of individual factors in shaping the financial decisions of entities of the national economy.

Opis:
The readiness to sacrifice profit while making socially responsible investments among millennials, as future investors and managers, was examined. Specifically, a multi-level perspective on willingness to pay for socially responsible investment was assumed to understand how nationality, personal values and investment knowledge affect millennials’ readiness to sacrifice profit to achieve sustainability goals. Using survey data of 521 business students from Italy, Poland and Ukraine, it is showed that a considerable share of millennials prefer social and environmental performance of investment over financial return and that their nationality is the most powerful factor in explaining willingness to pay for socially responsible investment along with their sensitivity to environmental issues that takes the leading role among all personal values motivating investors to accept lower rates of return. The results can be relevant for financial institutions aiming at developing socially responsible investment products. Policy implications of the results are insights into nationality-related tensions while Europe-wide regulation of socially responsible investment could enter into force.

The purpose of the article/hypothesis: The purpose of the paper is to present the historical background of sustainable development and importance of sustainable finance, and to discuss the most important challenges currently facing sustainable finance. The article verifies the research hypothesis: recent changes (implementing of the EBA Action Plan, the Sustainable Finance Disclosure Regulations and facing the COVID-19) in the finance sector can help institutions pursue an effective, sustainable development policy. Methodology: The article contains an extensive literature review of the sustainable development policy (including legal acts). Results of the research: Sustainable development in the finance sector plays an important role and is currently facing three main challenges: the implementation of the EBA Action Plan, the Sustainable Finance Disclosure Regulation and COVID-19. The EBA Action Plan and SFDRs may initially require financial institutions to change their policy and thus complicate their operations, but later bring only benefits (e.g. transparency). On the other hand, the COVID-19 pandemic is a significant obstacle to the implementation of the sustainable development policy due to countries and entities focused on fighting this threat (including using financial resources). However, it should be mentioned that sustainable development brings long-term effects (including more effective development), thanks to which companies can achieve the desired benefits and overcome the obstacles and crises caused by the pandemic and future crisis.

The financial sector is highly affected by the spectre of climate change and other sustainability-related factors, as recognised by various global and EU policies. The 2015 Paris Agreement enshrines the signatories’ goal to make “finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.” The European Union, since the European Commission’s 2018 Sustainable Finance Action Plan, has introduced an array of regulations intended to facilitate private investment in transition as well as to include ESG risk management in the prudential regulation. The article tracks and analyses the latter interventions with view to assess their coherence and to identify the potential long-term effects, in the context of the persistent barriers to the development of the Polish sustainable finance sector.

Research background: Fintech development shapes corporate investment efficiency and economic growth with innovative tools, and can decrease financing constraints of enterprises, enabling direct and indirect financing and furthering inter-bank competition. Crowdfunding- and blockchain-based fintech operations harness deep and maching learning algorithms, augmented and virtual reality technologies, and big data analytics in mobile payment transactions. Purpose of the article: We show that fintechs have reconfigured financial service delivery by harnessing AI-based data-driven algorithms and cloud and blockchain technologies. Fintech optimizes financial organization and services, economic structures and growth, data analysis, and digital banking performance.  Machine learning algorithms can streamline payment operation capabilities and process promptness, ensuring smooth operational flows, assessing risks, and detecting frauds and money laundering by historical data and customer behavior analysis across instant payment networks and infrastructures.

Data visualization tools: Dimensions and VOSviewer. Reporting quality assessment tool: PRISMA. Findings & value added: Fintech development enables organizational innovation by mitigating information asymmetry and financing limitations while providing financial assistance and tax incentives in relation to products and services. The fintech growth has influenced the dynamic intermediary function of financial institutions in terms of sustainability and economic development. Fintech and natural resources negatively influence, while green innovations and financial development further, environmental sustainability.

Opis:
Sustainable development, as a new political and economic doctrine of the global economy, has been manifesting for a long time in the energy transformation of the EU Member States. In July 2021, the European Commission renewed its sustainable finance strategy, pointing out that in the current decade, Europe will need additional investments to achieve its climate targets, expecting, in connection with their implementation, an increase in private sector expenditure. Financial institutions, including banks, joined this process. The article presents the results of a questionnaire survey conducted among representatives of the largest commercial banks in Poland, aimed at identifying the importance of greening their loan portfolios. The main aim of the paper is the exegesis of bank risk, taking into account the escalation due to factors that have destabilized banks’ lending activity in recent years, including the growing ESG (Environmental, Social and Governance) risk. The following research methods were used: survey research, a literature review, observation method, synthesis method and cause-and-effect analysis – all of which enabled the adoption of the main research hypothesis (H1), which assumes that the constantly growing interest and involvement of domestic banks in green loans increases the regulatory mix of bank risk, becoming a serious challenge for the banking compliance function. The research results presented in the article indicate that banking institutions in Poland are increasing their involvement in the implementation of sustainable finance assumptions, and green investments have better chances of financing in commercial banks in Poland. However, despite the ongoing process of greening the credit portfolios of commercial banks in Poland, financing green investments does not change their approach to bank risk management.

Opis:
The paper presented intends to fill up a gap in surveying the Hotelling Rule by taking a company based, microeconomic approach based on analyses of annual reports. Using selected data three fundamental hyphothesis are tested: 1) growth rate of margins (“net margins” including a capital charge) per unit realized by mining companies must exceed a rate equal to their cost of capital, 2) output shall follow deviations from the Hotelling growth line, 3) margins shall follow a path set by individually defined expected rate of return. The analysis was based on 5 leading gold producers, responsible for ca 15–20% of global primary production, all of them public and listed on a stock exchange for the entire period of 2004–2019/2020. As margin shall grow at a rate compensating individual risk of a company in consideration, they shall not be homogenous. At 1st step industry WACC was adopted to calculate a normalized capital charge. The calculations revealed no support for Hotelling Rule. There is no evidence that over a period of above 15 years margins follow any path determined by a growing expotential function, following a compound rate. Subsequently it was checked whether output volume is corrected due to development of actual versus expected (resulting from the Hotelling Rule) margin values. Selected companies were near indifferent to this parameter while taking decisions in area of volumes supplied. Neither there is no evidence of relation between changes in output and margins. Finally, it was checked whether differences between expected and actual margins’ growth paths could be described by a linear function, resulting from consequent adoption of a risk rate component. Here neither any evidence was found. In conclusion no support for the Hotelling rule was identified.
Prezentowany artykuł ma na celu wypełnienie luki w badaniach nad twierdzeniem Hotellinga poprzez przyjęcie podejścia mikroekonomicznego, opartego na analizie sprawozdań finansowych konkretnych firm górniczych. Wykorzystując zawarte w nich dane, poddano sprawdzeniu trzy hipotezy: 1) stopa wzrostu marży jednostkowej netto (z uwzględnieniem kosztu kapitału) musi być wyższa niż koszt kapitału, 2) zmiany wolumenu produkcji powinny odzwierciedlać odchylenia od stopy wzrostu marż wyznaczonych twierdzeniem Hotellinga, 3) marże powinny wzrastać zgodnie z indywidualnie wyznaczoną przez każdego producenta stopą wzrostu. Analizę przeprowadzono na przykładzie 5 wiodących producentów złota, którzy dostarczali 15–20% podaży pierwotnej (z wyłączeniem odzysku) tego metalu, notowanych na giełdach w całym badanym okresie. Ponieważ wzrost marż powinien kompensować indywidualne ryzyko każdej z firm, nie powinien on być homogeniczny. Jednak w pierwszym kroku średnioważony koszt kapitału (WACC) dla całego górnictwa złota został wykorzystany dla wyznaczenia kosztu kapitału. Obliczenia wykazały brak zgodności z twierdzeniem Hotellinga. Nie znaleziono dowodu, że w 15-letnim badanym okresie wzrost marż odpowiadał jakiejkolwiek wykładniczej funkcji. Następnie zbadano, czy wolumen produkcji był korygowany tak, aby przeciwdziałać odchyleniom od teoretycznej ścieżki wzrostu marż wyznaczonej twierdzeniem Hotellinga. Wykazano, że korporacje podejmowały decyzje o wydobyciu niezależnie od zmian w marżach. Tak samo nie znaleziono dowodu na zbieżność pomiędzy poziomem ich indywidualnej produkcji a wielkością ich marż. W końcu sprawdzono, czy różnice pomiędzy oczekiwanymi a uzyskiwanymi marżami mogą być opisane przez statystyczną zależność w postaci funkcji liniowej mogącej wynikać z zastosowania innej stopy ryzyka niż tej homogenicznej przyjętej pierwotnie do obliczeń. Tu też nie znaleziono żadnej przesłanki potwierdzającej taką zależność. W konsekwencji stwierdzono brak przesłanek uzasadniających stosowanie twierdzenia Hotellinga na poziomie mikroekonomicznym.
