Formalism versus purposivism in Islamic jurisprudence : the case of Islamic finance law

This manuscript critically discusses the current implications of the scriptural injunctions against gharar and maysir. It elaborates how overlooking the features of the contemporary world and adopting a formalistic approach in Islamic jurisprudence have led to absurdity in the implication of the doctrines of gharar and maysir for Muslims’ financial activities. The manuscript also underscores the necessity of adopting the maqāsid approach (purposivism) in Islamic jurisprudence. It propounds that the cogent concern of the injunctions could have been an initiative for Islamic scholars to establish an advanced contract law and to promote transparency in economic activities if a maqāsid approach had been adopted in Islamic jurisprudence.Publisher PDFPeer reviewe

Finance-growth nexus and dual-banking systems : relative importance of Islamic banks

This paper investigates the relative importance of Islamic banks, alongside their conventional counterparts, in relation to banking and financial development and economic welfare. Using a sample of 22 Muslim countries, with dual-banking systems, during the period 1999–2011, this paper reports some significant positive relationship between the market share of Islamic banks and the development of financial intermediation, financial deepening and economic welfare, particularly in low income or predominantly Muslim countries, and countries with a comparatively higher uncertainty avoidance index. Additionally, the results reveal that a greater market share of Islamic banks is associated with higher efficiency of conventional banks.PostprintPeer reviewe

Finance-Growth Nexus and Dual Banking System: Relative Importance of Islamic Banks

This paper investigates the relationship between the coexistence of Islamic banks alongside their conventional counterparts and the quantitative and qualitative development of commercial banking and economic welfare. We study 22 Muslim countries with a dual banking system during the 1999-2009 period and find a positive relationship between the market share of Islamic banks and the development of financial intermediation and economic growth. The results also show a negative linkage between Islamic banks' presence and income inequality and poverty. Moreover, a greater market share of Islamic banks is associated with lower credit risk and cost inefficiency of conventional banks in certain countries. The extent and modality of the relationships considerably depend on the institutional environment within which a dual banking system operates

Stock price synchronicity and price informativeness : evidence from a regulatory change in the U.S. banking industry

Whether return synchronicity is associated with higher or lower stock price informativeness is still an ongoing debate in the academic literature. This paper contributes to this debate by exploiting an exogenous shock, provided by a regulatory change introduced by the Federal Reserve in 2015, and examining its impact on return synchronicity using a sample of U.S. listed bank holding companies (BHCs) operating during the period of 2014: Q3 – 2016: Q2. Applying a regression discontinuity design, we find that return synchronicity of treated BHCs decreases after the regulatory change. This finding suggests that lower return synchronicity represents lower stock price informativeness.PostprintPeer reviewe

Flood, farms and credit: The role of branch banking in the era of climate change

Using Iran’s unexpected flood in April 2019 as a natural experiment, we show that local branches bridge the time gap between the disaster and governmental aids by immediately increasing their lending for two months following the flood. Analyzing proprietary information on more than 53,000 farmers, we find that farmers with a stronger relationship with their branch - particularly younger and females - are more likely to receive a recovery loan. Our findings underscore that despite recent technological advancements, relationship-based branch banking is still important for agrarian societies during catastrophic events

The sale of failed banks : the importance of their branch networks and of the acquirer's financial strength

Funding: The authors acknowledge funding for data by the School of Management, University of St Andrews.This paper investigates the pricing of insolvent banks in the U.S. that are sold under the purchase and assumption resolution method of the Federal Deposit Insurance Corporation (FDIC). We consider quarterly data for 444 acquisitions of insolvent U.S. banks between 2009 and 2016. We find that acquirers not only pay higher prices for insolvent banks with larger core deposits, as has been highlighted by the literature (and is consistent with the FDIC’s beliefs), but also for those banks with larger branch networks that are less dispersed geographically. When the acquirers bid (separately) for the assets of the insolvent banks, they place a positive value on the number of branches of the insolvent bank, but appear to be insensitive to geographic dispersion. Acquirers also pay more for banks with a national charter. The results additionally show that failed banks are most likely to be acquired by relatively large and highly capitalized banks whose organic growth is not affected in the years following the acquisition. Overall, our findings contribute to a better understanding of the implications of the purchase and assumption resolution method for the FDIC and for the banking industry.Peer reviewe

Resilience of environmental and social stocks under stress : lessons from the COVID-19 pandemic

This paper examines whether environmental and social (ES) activities affect the resiliency of firms during the COVID-19 crisis. We study a sample of 330 firms operating in five developed countries: Canada, France, Japan, the UK and the US. Our analysis shows that US firms with a high ES ranking experienced a significantly lower stock price range volatility during the Covid stock market rundown of February-March 2020. Such findings also hold for Japanese firms but only later on after the introduction of government support. In terms of returns, compared to their peers with a low ES ranking, Japanese and UK stock prices with a high ES ranking suffered more during and after the market rundown. For other countries, we do not find significant differences in stock price behavior based on ES ratings. Our findings suggest that engaging with ES activities is not associated with a better or worse performance during crisis times, which has important implications for investors and managers.Publisher PDFPeer reviewe

Non-interest income and bank lending

This paper examines the influence of non-interest activities on bank lending in terms of loan quality and interest spread. We also investigate the possible existence of profit complementarities between non-interest activities and lending. Using quarterly data on 6,921 U.S. commercial banks between 2007:Q3 to 2016:Q3 we find that non-interest activities have no adverse influence on bank credit risk. This is the case for banks of different asset size (including systemically important banks) as well as for distressed banks. There is evidence that banks with assets between $100 million and$1 billion that have a greater share of fiduciary income have lower credit risk. They also have lower interest rates on loans secured by real estate, and higher franchise values, particularly post-crisis. Moreover, banks in the aforementioned size range benefit from synergies in joint production of non-interest income and lending, whereas other banks, in particular smaller banks (below $100 million in assets) suffer from diseconomies of joint production. Larger banks exhibit cross-subsidization between several non-interest activities and lending business.PostprintPeer reviewe

Heterogeneous market structure and systemic risk : evidence from dual banking systems

The authors acknowledge the financial support received from the PhD program in Economics and management of technology (DREAMT), at the University of Pavia.This paper investigates how banking system stability is affected when we combine Islamic and conventional finance under the same roof. We compare systemic resilience of three types of banks in six GCC member countries with dual banking systems: fully-fledged Islamic banks (IB), purely conventional banks (CB) and conventional banks with Islamic windows (CBw). We employ market-based systemic risk measures such as MES, SRISK and CoVaR to identify which sector is more vulnerable to a systemic event. We also compute weighted average GES to determine which sector is most synchronised with the market. Moreover, we use graphical network models to determine the most interconnected banking sector that can more easily spread a systemic shock to the whole system. Using a sample of observations on 79 publicly traded banks operating over the 2005–2014 period, we find that CBw is the least resilient sector to a systemic event, it has the highest synchronicity with the market, and it is the most interconnected banking sector during crisis times.PostprintPeer reviewe

Chlamydia trachomatis Serovar Distribution in Patients with Follicular Conjunctivitis in Iran

Objectives:Chlamydia trachomatis infects the urogenital tract and eyes. Anatomical tropism is correlated with serovars which are characterized according to the variation in the major outer membrane proteins encoded by the ompA gene. The aim of the present study was to determine the distribution of C. trachomatis serovars among patients with follicular conjunctivitis in Iran.Materials and Methods:A total of 68 conjunctival specimens from symptomatic adults were studied for the presence of C. trachomatis using polymerase chain reaction (PCR) analysis. Serovars were determined by Omp1 PCR-RFLP analysis.Results:C. trachomatis was detected in 38 (55.9%) of patients with follicular conjunctivitis, with higher C. trachomatis prevalence in the younger age groups. Twenty-six (38.2%) of these patients had a history of urinary tract infection. Four distinct serovars were identified in the conjunctiva samples using molecular genotyping. The most prevalent was serovar E, followed by G, I, and F.Conclusion:Our serovar distribution indicated that chlamydial follicular conjunctivitis usually has a genital source. Genital serovars may cause eye diseases, especially in sexually active adults. On the other hand, conjunctivitis might be the only sign of sexually transmitted infection. Therefore, genotyping C. trachomatis in ocular and genital specimens could be beneficial for acquiring more detailed epidemiological information about the etiology of the disease and monitoring treatment success
