This study explores the relationship between income inequality, economic growth, and unemployment in Greece from 2003 to 2020, encompassing key economic phases: pre-crisis, crisis, memoranda, and post-memoranda. The aim is to analyze how economic growth (logarithm of GDP-LOGGDP) and unemployment influenced income inequality (GINI coefficient) during periods of economic turmoil and recovery. Using linear regression analysis on 18 years of annual data, this study identifies significant relationships between the variables, with diagnostic tests confirming model robustness. The findings reveal a strong positive and statistically significant relationship between LOGGDP and income inequality, indicating that economic growth, without effective redistributive mechanisms, exacerbated disparities. Unemployment had an even stronger positive effect on inequality, highlighting its role in deepening income disparities, particularly during the crisis years marked by economic contraction and austerity measures. These results underline the critical need for balanced economic policies that promote inclusive growth while addressing structural inequalities and labor market vulnerabilities. This study also employs advanced econometric methods, including Vector Autoregression (VAR), Vector Error Correction Model (VECM), and Granger Causality Test, to analyze the dynamics between GDP (LOGGDP), income inequality (GINI), and unemployment. The Granger Test reveals that unemployment Granger-causes GDP with a two-period lag, highlighting the importance of labor market conditions for economic growth, while no direct causal relationship is found between GDP and inequality. These methods provide deeper insights into the short- and long-term interactions, offering valuable guidance for balanced economic policymaking.

While prior research has established direct relationships between strategic risk integration and ESG performance in banking, critical gaps remain in understanding the transformation mechanisms, particularly in emerging markets. This study investigated how banking innovation capacity mediates the relationship between strategic risk integration and ESG performance in Jordanian banks. Drawing on dynamic capabilities theory and questionnaire data from 165 banking executives (71.7% response rate), the results revealed that strategic risk integration significantly influences ESG performance both directly and indirectly through banking innovation capacity. The multi-group analysis showed institutional invariance between commercial and Islamic banks, suggesting the generalizability of these relationships. The findings advance dynamic capabilities theory by demonstrating innovation capacity’s role as a transformative mechanism in banking sustainability and provide practical insights for emerging market banks seeking to enhance ESG performance through integrated risk management and innovation strategies.

The risk-neutral density is a fundamental concept in pricing financial derivatives, risk management, and assessing financial markets’ perceptions over significant political or economic events. In this paper, we propose a new nonparametric method for estimating the risk-neutral density using natural cubic splines (NCS). The estimated density is twice continuously differentiable with linear tails at both ends. Our method targets the logarithm of the underlying asset price, releasing the restriction to the positive domain. We theoretically prove the consistency of our NCS method. We conduct a comprehensive empirical study comparing the proposed NCS method with a piecewise constant method, a uniform quartic B-spline method, and a cubic spline method from the literature using 20 years of S&P 500 index option data. The empirical results show that our NCS method is more robust than the piecewise constant method, which can only produce a discontinuous density, especially for options with maturities longer than six months. Moreover, our NCS method outperforms other historical continuous methods in terms of optimization feasibility and option price estimation.

This study examined the influence of cognitive biases on financial literacy test outcomes across four generational groups: Gen Z, Millennials, Gen X, and Baby Boomers. Using the National Financial Capability Test and an online in silico experiment, we analyzed how cognitive biases influence the likely responses of each generation. The results indicate that the current test format aligns more closely with Baby Boomers, who are less affected by certain biases but tend to exhibit resistance to new financial strategies. A key contribution of this research is the identification of generational bias profiles and actionable recommendations for tailoring financial literacy assessments to reflect these differences. Our approach not only advances behavioral finance literature but also introduces innovative methodology through AI-driven simulations, providing a replicable framework for exploring cognitive influences in decision-making. The findings underscore the need for tailored financial education programs that consider these cognitive biases, aiming to foster unbiased financial decision-making across age groups.

This study investigates how an increase in the quality of business ventures, measured as their success probability, affects trust and return on investment (ROI) in situations where the investor–entrepreneur interaction is affected by moral hazard and asymmetric information. We model a repeated trust problem between investors and entrepreneurs, featuring moral hazard and adverse selection. Hidden Markov techniques and computer simulations are used to derive the main results. We find that trust and ROI may decline as quality improves. Although lenders tend to reduce the requirements for granting initial credit, they nevertheless become less tolerant of current borrowers who fail to pay back. Additionally, we demonstrate a novel substitution effect, where lenders prefer new borrowers over existing borrowers that experienced early failures. The main conclusions of our study are that while impressing early on is effective in gaining first access to credit, it may nevertheless hurt the cause of getting credit in subsequent periods, following an early failure. In business environments plagued with ex post moral hazard, entrepreneurs might do better by gaining trust first and impressing later. Furthermore, our results imply that in a thriving economy, not only are bad loans made, but good loans are lost as well.

This study addresses FinTech implementation challenges in the banking industry in Palestine. This was accomplished by adopting qualitative research methods. Semi-structured interviews were conducted with interviewees from the Palestinian Monetary Authority, banks, and FinTech companies. Thematic analysis was conducted using NVivo 12 software to identify themes in the interview scripts. Research outcomes suggest that FinTech development in Palestine encounters a range of multifaceted challenges, which can be categorised using the TOE (technological, organisational, environmental) framework. On the technological front, issues such as underdeveloped IT and telecommunications infrastructure, restricted mobile frequencies due to Israeli occupation, limited IT expertise, cyber risks, low digital literacy, and minimal FinTech awareness hinder progress. Organizationally, resistance to change, inadequate agility, limited digital skills, and slow Sharia compliance updates in Islamic banking impede innovation. Environmentally, the absence of a dedicated FinTech framework, unclear regulatory guidance, limited market size, and strict AML/CFT regulations create uncertainties for non-bank entities and restrict investment opportunities. Addressing these interconnected barriers requires coordinated efforts across legal, financial, and technological sectors to foster FinTech integration and growth in Palestine.

This study explores the financialization of agricultural commodities, focusing on how financial derivatives and index funds impact the volatility of agro-food markets. Using a Dynamic Conditional Correlation (DCC) GARCH model, we analyze volatility spillovers among key agricultural commodities, particularly maize, and related financial assets over a sample period from 2007 to 2020. Our analysis includes major financial assets like Exchange-Traded Funds (ETFs), the S&P 500 index, and agribusiness corporations such as ADM and Bunge and the largest corn flour producer, GRUMA. The results indicate that financial speculation, especially via passive investments such as ETFs, has intensified price volatility in commodity futures, leading to a systemic risk increase within the sector. This study provides empirical evidence of increased market integration between the agro-food sector and financial markets, underscoring risks to food security and economic stability. We conclude with recommendations for regulatory actions to mitigate systemic risks posed by the growing financial influence in agricultural markets.

This work aims to create and validate the digital financial knowledge scale (DFKS). Three studies were carried out, including a focus group, expert validation, pre-testing, and the application of item response theory. From these procedures, two versions of the scale were constructed and validated. An evaluation and classification methodology was proposed. Two versions for measuring digital financial knowledge are presented. The long version is composed of 40 items and the short version has 26 items. Applying the proposed methodology, it is possible to classify the level of digital financial knowledge as low, intermediate, or high. The DFKS can be useful for both financial system agents and governments and researchers, who can use it in different contexts. In the banking sector, identifying the level of digital financial knowledge can reduce risks, as losses suffered by clients due to an uninformed adoption of digital banking services break the relationship of trust and can lead to lower financial inclusion.

We use a laboratory experiment to explore the effect of a change in pre-trade anonymity in a quote-driven dealer-to-customer market, organised as a request for quote (RFQ). We consider two treatments in which dealers interact with two types of customers (informed or uninformed). In the first treatment, there is no anonymity: dealers know whether the customer that sent them the request for quote is informed or uninformed. In the second treatment, there is complete anonymity: dealers do not know the type of customers they are interacting with. We find that anonymity improves price efficiency, whereas it does not adversely impact dealers’ trading profits. Our results contribute to the debate on transparency versus the adoption of anonymity in financial markets.

This study investigated the impact of mobile financial services on the shadow economy in Southern Africa countries and explored how regulatory quality moderates this relationship. Utilising panel data from 1993 to 2022, this study employed dynamic common-correlated effect (DCCE) and dynamic seemingly unrelated regression (DSUR) methods to assess long-run effects. The findings reveal that increased mobile financial services adoption markedly diminishes the scale of the underground economy by enhancing transaction transparency and accessibility, thus drawing more participants into the formal economy. The results are consistent across DCCE and DSUR estimations. Additionally, improvements in regulatory quality further diminish the shadow economy by bolstering trust and compliance within the financial system, suggesting that well-crafted regulations enhance the effectiveness of mobile financial services. Economic and financial sector developments also contribute to a reduced shadow economy, indicating that broader economic growth and advanced financial systems facilitate formal sector participation. Conversely, larger public sector expenditures appear to expand the shadow economy enterprises, likely due to inefficient resource allocation and increased fiscal burdens that push economic activities underground. Policy recommendations include the need to expand mobile financial services infrastructure, enhance financial literacy, and optimise financial regulatory frameworks to balance oversight with innovation encouragement.
