Design/methodology/approach An online survey was used to obtain a sample of 246 respondents familiar with P2P accommodation platforms. The model was tested using SmartPLS. Findings The results showed a positive correlation between perceived betrayal and NWOM, vindictive complaining and patronage reduction. Unexpectedly, prior trust had positive moderating effects. High levels of prior trust caused more negative customer reactions than low levels of prior trust. Practical implications The findings of this study caution firms about the potential risks to rely on the forgiveness and tolerance of highly trusted customers who may retaliate fiercely to double deviations. Originality/value This research unveils the prior trust paradox. Customers' prior trust magnified the negative impact of double-deviation experiences. This study contributes to the service-recovery literature by questioning the buffer effect of prior trust in the context of a double deviation.","PeriodicalId":46475,"journal":{"name":"EuroMed Journal of Business","volume":"6 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to examine the impact of financial technology on the relationship between CSR and banks' financial stability. Specifically, it investigates the moderating effect of fintech on the association between CSR and the financial stability of conventional banks operating in Qatar, UAE, Saudi Arabia, Kuwait, Bahrain, Jordan, Pakistan and Turkey from 2010 to 2021. Design/methodology/approach To achieve the authors’ objective, the authors apply Baron and Kenny's three-link model, tested with fixed and random effects regression models. Findings The results reveal that the development of fintech decreases banks' financial stability, whereas it promotes banks' involvement in CSR strategies. Furthermore, the findings indicate that fintech plays a moderating role in the relationship between CSR and financial stability. It positively moderates the impact of CSR on financial stability. The robustness analysis highlights the mutual reinforcement of fintech and CSR dimensions in improving the financial stability of banks.

Design/methodology/approach To achieve the study's purposes, 330 observations are extracted from 30 oil and gas firms for the period between 2010 and 2020, and the estimation method of the Generalized Least Squares (GLS) is used. Actually, the CSR is proxied using the ESG (environmental, social, and governance) score, and the stock price volatility is measured by the degree of stock price variations over 12 months, according to the last 52 week's price. Findings The main findings indicate that CSR negatively impacts the stock price volatility. Nonetheless, this negative relationship is moderated positively by tax avoidance. This result is robust to the variation in the measure of volatility, namely the systematic risk. Practical implications This research is helpful for investors to manage their portfolio risk as this article highlights the importance of engaging in sustainable development to reduce financial risk. This study also helps regulators and policymakers, such as environmental agencies and tax authorities, to reassess their control with oil and gas firms and record them according to their CSR practices, because this article emphasizes that it is not fair to pay taxes and engage in CSR practices at the same time. Originality/value The impact of CSR on stock price volatility is widely treated for firms. Nevertheless, the mechanisms that may affect this relationship are still seldom discussed. This study attempts to examine the impact of tax avoidance on the CSR–stock price volatility relationship for the oil and gas industry.","PeriodicalId":46475,"journal":{"name":"EuroMed Journal of Business","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136293615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The impact of supervision on bank risk: empirical evidence from the Tunisian context","authors":"Sana Belgacem, Manel Hadriche, Fethi Belhaj","doi":"10.1108/emjb-01-2023-0006","DOIUrl":"https://doi.org/10.1108/emjb-01-2023-0006","url":null,"abstract":"Purpose The purpose of this paper is to examine the impact of supervision on banking risk to determine whether prudential measures taken especially after financial crises are effective in limiting banking risks. Design/methodology/approach The empirical study focused on 210 annual reports of almost all Tunisian banks during the 2010–2019 period. Banking supervision effectiveness is measured by enforcement outputs (i.e. on-site audits and sanctions). The generalized least squares method of multivariate analysis was used to analyze this study. Findings The results show that supervision set up and on-site audits reduce bank risk, while the relationship between sanctions and risk appears to be non-significant. The results still hold after robustness tests by changing the bank's risk-taking indicators. Practical implications This study has important implications for managers and investors in the Tunisian context. In particular, the findings provide microevidence for the impact of supervision in Tunisian banks to reduce their risk-taking. The empirical results have important implications for the decision-making of bank managers and regulators in Tunisia as well as for relevant actors in similar emerging economies. Originality/value This study extends the previous literature on supervision by examining the relationship between supervision and banking risk in an emerging country, which has been little explored, Tunisia in particular. Furthermore, this study examines whether supervision reduces risk borne by Tunisian banks, and to the best of the researchers' knowledge, it is one of the pioneering studies of supervision in the Tunisian market. This latter market has different economic, political and social attributes compared to developed countries. So, this paper helps to clarify the impact of supervision enforcement and macroprudential policies. In addition, this paper strongly contributes to the various stakeholders “understanding of the importance and implication of supervision practices. However, since banks tend not to reduce their participation in risky activities to seek higher profits, supervisory policymakers and practitioners should also take a closer look at the composition of banks” investment portfolios to reduce moral hazard and regulatory arbitrage behavior. Empirically, the authors measure supervision by on-site audits and sanctions and examine how they affect bank risk level, which was never approached in Tunisia.","PeriodicalId":46475,"journal":{"name":"EuroMed Journal of Business","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135131742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach The study used the newly developed panel autoregressive distributed lagged (ARDL) approach in order to address any potential endogeneity between research variables. Findings The empirical results show a unidirectional causality in the long run from oil price to both economic growth and banking sector development for oil-importing countries. Also, banking sector development not only leads directly to economic growth but also can play a moderator role in the oil price—economic growth nexus. Research limitations/implications The study has two principal limitations. On the one hand, this study was conducted in a relatively limited sample of countries. On the other hand, the study did not consider others indicators for banking sector development and others macroeconomic variables. Practical implications The results found have imperative implications for banks' managers, regulators and researchers. Bank managers should be more concerned with the negative repercussions of oil price fluctuations on the development of their banks. The regulatory authorities must emphasize policies and strategies to further strengthen their banking sector in order to alleviate the negative influence of oil price shocks on economic growth. Researchers focused on finance-growth nexus must take into account the potential influence of oil price shocks.
