Selectivity and Transparency in Social Banking: Evidence from Europe

How do social banks signal their social commitment to motivated funders? We hypothesize that two main channels are used: selectivity and transparency. We test these predictions using a rich dataset comprising balancesheet information on 5,000 European banks over the period from 1998 to 2013. The results suggest that social screening leads social banks to higher project selectivity compared to mainstream banks. Social banks also tend to be more transparent than other banks. However, combining selectivity and transparency can result in excess liquidity. Overall, the empirical findings not only confirm our theoretical hypotheses, but also raise challenging issues regarding the management of social banks.     

Financial innovation,systematic risk and commercial banks’ stability in China: theory and evidence

We are dedicated to revealing the impacts of financial innovation and systematic risk on commercial banks’ stability in China, both theoretically and empirically. We established a theoretical model and derived a theoretical mechanism from this model revealing two distinctive patterns of the impacts determined by the profitability of financial derivatives: the impacts of financial innovation and systematic risk on banks’ stability in China are linear under the circumstances of a positive expected risk premium of financial derivatives; conversely, the impacts can be linear, U-shaped or cubic when the expected risk premium is negative. We make three propositions to analyse the patterns and conditions of these impacts in detail. In the empirical analysis, we do not focus only on the banking industry but also on individual commercial banks. The empirical results demonstrate that the impact of financial innovation on both the banking industry’s and most individual commercial banks’ stability are U-shaped, and the impact of systematic risk on the banking industry’s and on only one commercial bank’s stability are significantly linear, which confirms certain conditions mentioned in the theoretical propositions. Finally, the study’s conclusions are presented, and the contributions of the article to future study are also mentioned.     

Shari’ah supervision,corporate governance and performance: Conventional vs. Islamic banks

The performance and accountability of boards of directors and effectiveness of governance mechanisms continue to be a matter of concern. Focusing on differences between conventional banks and Islamic banks, we examine the effect of (i) Shari’ah supervision boards, (ii) board structure and (iii) CEO-power on performance during the period 2005–2011. We find Shari’ah supervision boards positively impact on Islamic banks’ performance when they perform a supervisory role, but the impact is negligible when they have only an advisory role. The effect of board structure (board size and board independence) and CEO power (CEO-chair duality and internally recruited CEO) on the performance of Islamic banks is overall negative. Our findings provide support for the positive contribution of Shari’ah supervision boards but also emphasize the need for enforcement and regulatory mechanism for them to be more effective.     

Downside risk in Dow Jones Islamic equity indices: Precious metals and portfolio diversification before and after the COVID-19 bear market

Besides great turmoil in financial markets, the COVID-19 pandemic also disrupted the global supply chain, putting the precious metal market into great uncertainty. In this study, we revisit the diversifying role of precious metals – gold, silver, and platinum – for six Dow Jones Islamic (DJI) equity index portfolios using a battery of tests: dynamic conditional correlations (DCCs), four-moment modified value at risk (VaR) and conditional VaR, and global minimum-variance (GMV) portfolio approach. Our empirical results exhibit drastically increased DCCs between sample assets during the COVID period; however, pairing gold with any of the DJI equity indices (except for the Asia-Pacific region) decreases the downside risk of these portfolios. Other precious metals (silver and platinum) do not provide such benefits. Furthermore, we find that a higher allocation of wealth in DJI Japanese equities and gold is required to achieve a GMV portfolio in the post-COVID-19 era, implying higher transaction (hedging) costs to rebalance portfolios (weights) accordingly. Our out-of-sample tests examining the global financial crisis, European debt crisis, and extended sample (2000–2020) periods yield similar findings as gold glitters across all market conditions. Overall, our findings provide notable practical implications for both domestic and international investors.     

A shared boundary object: Financial innovation and engineering in Islamic financial institutions

This paper explores the way in which ethico-faith-based rules act as a boundary object in constraining the process of financial innovation and engineering (FIE) in Islamic Financial Institutions (IFIs). The paper examines how this faith-based approach is enacted in the FIE process amid different social worlds and groups that cooperate without consensus within IFIs. We contribute to studies of governance in faith-based organizations, by identifying the plasticity of faith-based rules that act as boundary objects in the governance of the FIE process. The plasticity of ethico-faith based rules allows coordination among local and global actors with intersecting faith-based values, logics, and interests. IFIs ensure that the products of FIE become an integral part of and as compatible as possible with the logics of global financial markets.     

Eating at the limits: Barriers to the emergence of social enterprise initiatives in the Australian emergency food relief sector

This article explores the absence of social enterprise responses to food insecurity in Australia. Continued growth in demand from chronically food insecure consumers and criticism of the dominant food bank model of gifted food support has led to the development of ‘community supermarkets’ that charge consumers for donated food in countries including Canada, the United Kingdom, France and Italy, but not in Australia. This research investigates barriers to the development of community supermarkets in Australia through in-depth interviews with senior staff within seven organizations involved in the food relief supply chain, as well as a pilot survey of 38 food insecure consumers. The results of this research are analyzed through the lens of ‘voluntary failure’ theory and highlight systemic barriers to the reach of social enterprise as a mechanism for addressing food insecurity.     

Foreign bank subsidiaries’ risk-taking behavior: Impact of home and host country national culture

This paper examines whether the risk-taking behavior of foreign affiliates of multinational banks is more influenced by the national culture of their parent banks’ home country or the national culture of foreign affiliates’ host country. The study uses a dataset of 292 foreign affiliates (i.e., subsidiaries or branch operations) operating in 66 countries having parent banks in 26 countries for empirical analysis. National culture of both home and host countries is measured with four dimensions—uncertainty avoidance, individualism, masculinity and power distance—of Hofstede's framework of national culture. Findings suggest that the national culture of parent banks’ home country has higher impact on the risk-taking behavior of foreign affiliates of multinational banks than the national culture of their host country. Specifically, foreign affiliates’ risk-taking is higher if parent banks’ home country has low uncertainty avoidance, high individualism and low power distance cultural values. This study extends our understanding that how informal institutions, such as the national culture, influence the financial decisions in multinational banks.     

Internationalization of Korean banks during crises: The network view of learning and commitment

This study addresses the effect of crisis on bank internationalization from the perspective of network theory. Employing the internationalization process (IP) model, we particularly examine the role of learning and commitment in overseas expansion for banking services under stable and critical periods. Following the IP model and business network approach, the study develops a theoretical view for analysis of international banks from South Korea. South Korean banks are selected as they experienced two global crises, one in 1998 and the other in 2008. Findings show that while the first crisis in 1998 stopped internationalization, the 2008 crisis stimulated firms to find new markets, especially in developing countries. Different from the studies showing that commitment increases in stable periods and decreases in crisis, this study contributes to the finding that experiencing earlier crises enhances learning and increases commitment needed for expansion and strengthening of the business network.
