Islamic versus conventional banks in the GCC countries: A comparative study using classification techniques

This paper contributes to the empirical literature on Islamic finance by investigating the feature of Islamic and conventional banks in Gulf Cooperation Council (GCC) countries over the period 2003–2010. We use parametric and non-parametric classification models (Linear discriminant analysis, Logistic regression, Tree of classification and Neural network) to examine whether financial ratios can be used to distinguish between Islamic and conventional banks. Univariate results show that Islamic banks are, on average, more profitable, more liquid, better capitalized, and have lower credit risk than conventional banks. We also find that Islamic banks are, on average, less involved in off-balance sheet activities and have more operating leverage than their conventional peers. Results from classification models show that the two types of banks may be differentiated in terms of credit and insolvency risk, operating leverage and off-balance sheet activities, but not in terms of profitability and liquidity. More interestingly, we find that the recent global financial crisis has a negative impact on the profitability for both Islamic and conventional banks, but time shifted. Finally, results show that Logit regression obtained slightly higher classification accuracies than other models.     

Impact of the global financial crisis on Islamic and conventional stocks and bonds

This study explores the impact of the global financial crisis (GFC) on Islamic and conventional stock and bond indices in 11 Islamic and eight non‐Islamic countries. We find that there are benefits of Islamic stocks during the GFC, particularly during the early stage of the crisis because Islamic institutions are prohibited from holding sub‐prime mortgage securities and derivatives. The strongest benefits of Islamic stocks are in the UK and USA. We conclude that there are benefits of risk reduction and stability for Islamic stocks during a financial crisis, although not necessarily during a global recession.     

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.     

Risk governance and financial stability: A comparative study of conventional and Islamic banks in the GCC

While the linkage between bank governance and financial stability has been discussed widely, empirical explorations of the strength of this relationship are scant. This paper examines the specific role of risk governance in promoting financial stability in banks. Using hand-collected data, it develops a Risk Governance Index (RGI) to measure the strength of risk governance structures and then examines its impact on four main indicators of financial stability for conventional and Islamic banks in the countries of Gulf Cooperation Council (GCC). The results from the dynamic panel models using two-step GMM method suggest that risk governance significantly contributes to the enhancement of the key financial stability measures. The RGI for Islamic banks is found to be smaller than their conventional counterparts and the regression results indicate that risk governance in Islamic banks has a negative impact on stability indicators. While the business models of Islamic banks have features that can enhance stability, poor risk governance can potentially negate this positive feature.

Controlling Investment Decisions: Depreciation- and Capital Charges

This paper examines a multiperiod principal-agent model in which a divisional manager has superior information regarding the profitability of an investment project available to his division. The manager also contributes to the periodic operating cash flows of his division through personally costly effort. We demonstrate that it is optimal for the principal to delegate the investment decision and to base the manager's compensation on the residual income performance measure. Our analysis points to a class of depreciation rules and to a particular capital charge rate which together ensure that a profitable (unprofitable) project makes a positive (negative) contribution to residual income in every period. As a consequence, the compensation parameters for each period can be chosen freely so as to address the moral hazard problems without impacting the manager's investment incentives.     

美国投资银行危机及其转型剖析

本文通过分析美国投资银行经营模式的缺陷,找出2008年美国投资银行危机及其转型的深刻原因。分析结果显示,融资模式的缺陷、过度依赖高风险业务是美国投资银行危机的内因,而外部监管漏洞放任了投资银行的经营管理,是投资银行危机的重要外因。投资银行危机促使美国主要独立投资银行转型为全能银行经营模式,这是美国银行业发展一个重要的转折点。但危机仅仅是投资银行转型的诱因,全能银行经营模式的相对优势是美国独立投资银行转型的根本原因。     

Efficiency and Dynamics of Islamic Investment: Evidence of Geopolitical Effects on Dow Jones Islamic Market Indexes

This paper analyzes both the market quality and price dynamics of a sample group of Islamic indexes. Our results highlight that efficient investment allocation is not compromised by the application of Shariah criteria. However, although few indexes impose an additional liquidity cost on investors, a vast majority of indexes present degrees of liquidity that are similar to conventional indexes. Ultimately, investors whose investment decisions are guided by religious principles do not bear significant additional costs of inefficiency but may have to accept that their portfolios are more sensitive to geopolitical events. However, Islamic indexes may contribute to the international diversification of investors' portfolios.     

Payout policy and ownership structure: The case of Islamic and conventional banks

Using a sample of Islamic and conventional financial institutions domiciled in 16 countries for the period 2000–2015, we examine how ownership structure affects dividend policy. Our main findings indicate that ownership identity is important in explaining dividend policy in these banks, albeit in different patterns. In particular, the results suggest that government ownership seems to exert negative effects on dividend payouts in both types of banks, which is in line with the preference of governments towards bank stability. With respect to family ownership, the impact is negative for conventional banks but positive for Islamic ones, consistent with agency theory. These results are to some extent similar in the case of foreign ownership where it is associated with a higher payout policy in Islamic banks, but not significant in conventional ones. Our results are robust to an array of additional analyses including propensity score matching.     

Capital expenditures and firm performance: evidence from a cross‐sectional analysis of stock returns

Using a simple two‐period model of investment, we show that there should be a nonlinear relation between a firm's investment‐to‐capital ratio and its subsequent stock returns. This prediction finds substantial empirical support. The evidence indicates that the slope of the investment function is negative at low investment levels, close to zero at intermediate investment levels and negative at high investment levels. Our results, which are robust to the use of narrowly‐ and broadly‐defined measures of capital investment, pose a challenge to the hypothesis that the negative cross‐sectional correlation between investment and stock returns is attributable to some sort of overinvestment phenomenon.     

A net stable funding ratio for Islamic banks and its impact on financial stability: An international investigation

The Islamic Financial Services Board (IFSB) is the standard setting body for the Islamic banking industry. The IFSB, while endorsing the Basel III accord, modified the criteria to calculate the Net Stable Funding Ratio (NSFR) to cater for the unique aspects of the Islamic banking industry. In this paper, we calculated the modified NSFR of 136 Islamic banks from 30 jurisdictions between 2000 and 2013 and explored the potential impact the requirements of this ratio has on the financial stability of Islamic banks after controlling for bank, country, and market-specific variables. The empirical findings suggest that the modified NSFR has a positive impact on the financial stability of Islamic banks during the sample period. However, the marginal impact of the NSFR on stability diminishes as the size of the bank increases. The results remained robust after applying an alternative measure of stability and using an alternative estimation model based on an instrumental variable approach. These results validate the use of the IFSB’s modified NSFR for Islamic banks as a regulatory measure.     

Growth Opportunities and Investment Decisions: A New Perspective on the Cost of Capital

This paper shows that it is not always correct to make an upward adjustment to the stock beta in calculating the hurdle rate for capital budgeting even when the project under consideration is riskier than existing assets. The paper also shows that the correct hurdle rate is smaller than the market capitalization rate calculated from the firm's stock beta when the project under consideration has the same risk as existing assets. In addition, it is shown that the market capitalization rate will be an underestimate (overestimate) of the correct hurdle rate when the risk of future assets is greater (smaller) than both the risk of assets in place and that of future capital expenditures. These new results are direct consequences of the insight that the firm's investment opportunities are in fact real call options written on underlying assets.     

A comparative performance of conventional and Islamic unit trusts: Market timing and persistence evidence

It is expected that the returns and resistance of Islamic mutual funds will be different from conventional mutual funds as the former have limited choices for portfolio diversification. This article analyses the performance of conventional and Islamic unit trusts for the period February 1995 to July 2012 in the Malaysian market, one of the most developed Islamic mutual fund markets. The performance analysis is based on four parameters: (i) risk-adjusted returns of unit trusts; (ii) market timing abilities; (iii) selection performance; and (iv) persistence. The results of this study suggest that the returns of both conventional and Islamic unit trusts have outperformed the market throughout the sample period. The results for market timing and selectivity are mostly the same for both categories of funds. However, Islamic unit trusts seem to have better resistance to market downturn than conventional unit trusts. The results of this research can be used by investors to identify funds or create portfolios that are more suitable for a recessionary scenario and for fund managers to better manage their portfolio performance during times when markets are likely to fall. The findings in this article are highly relevant for policymakers, investors and fund managers to determine policy matters, deciding on investment and marketing strategy for Islamic mutual funds.     

Islamic Banking Sustainability: A Review of Literature and Directions for Future Research

This study reviews literature on the Islamic banking sustainability and presents directions for future research. The article discourses scholars’ and practitioners’ views on the two perspectives of sustainability in relation to the objectives of Islamic banking and finance. That there are limited studies on Islamic banking sustainability is one of the major issues presented in the article. The study highlights essential issues on the sustainability without in-depth empirical analysis. The needs for long-term economic, social, and environmental sustainability are not a compromising issue. Therefore, Islamic banks must strike a balance between the institutional, societal, and environmental sustainability in order to achieve the objective of Sharia.     

Risk,return and mean‐variance efficiency of Islamic and non‐Islamic stocks: evidence from a unique Malaysian data set

We find that Islamic stocks are more mean–variance efficient than non‐Islamic stocks and the market because they reduce risk of the same level of returns. We combine a unique Malaysian data set of individual Islamic stocks (as opposed to aggregate stock indices) since 1997 with a new method where we apply Islamic business activity and financial ratio screens to the universe of Malaysian stocks. Both data sets show that Islamic stocks have an annualised standard deviation that is on average 3.43–3.78 percent points lower compared to non‐Islamic stocks. This lower variance of Islamic stocks is exclusively driven by financial ratio screens.     

Originators,wholesalers, and conduits: The marginal value of the contract rate on 30-year conventional mortgages

The model we present solves for the value of an incremental change in the mortgage contract given an expectation about the time the mortgage will be outstanding and a required return for this time span. The marginal value participants in the primary mortgage market place on the contract rate of a 30-year conventional mortgage determines the array of bids for new mortgage production. Mortgagors can issue mortgages at various discounts. High discounts are associated with low contract rates, and low discounts are associated with high contract rates. This article examines the way wholesale dealers and conduits value the various contract rates associated with current production of 30-year conventional mortgages.     

公允价值会计与市场投资异象研究——来自中国上市公司的经验证据

以2007～2010年我国A股公司为样本,研究了上市公司在采用公允价值计量方式后是否会产生新的投资异象以及造成这种投资异象的影响因素。运用均值T检验和Wilcoxon符号等级检验,并采用Fama-French三因素模型对样本公司进行回归。研究发现,在控制了市场风险、规模风险和账面市值比风险之后,投资策略仍然可获得超常回报率,并且公允价值变动损益占净利润比重大(小)的组,超常回报率低(高)。套利风险、交易成本是公允价值变动损益对净利润的波动性风险造成的投资异象的影响因素。交易成本越大,套利风险越高,错误定价越不容易被消除,其超常回报率也越高。     

基于风险选择与投资收益的外汇储备币种结构研究

随着外汇储备规模的不断增加,国家外汇储备投资的风险偏好亦会发生相应的变化。借鉴 J. H.Makin(1971)的方法,构建外汇储备币种结构配置理论模型,讨论在效用最大化的情况下,储备资产投资如何在安全性、流动性和盈利性三原则间进行权衡。假设外汇储备仅投资于美元和欧元两种币种资产,选取2000年初~2014年第三季度的10年期美国国债和欧元区公债季度数据,运用协整分析、格兰杰检验等方法进行的实证研究发现：储备货币在外汇储备中的比重与储备货币收益率及其三阶矩显著正相关,国家外汇储备投资总体而言是风险规避型的。
