Perceptions on the accessibility of Islamic banking in the UK—Challenges,opportunities and divergence in opinion

This study examines the views of UK-based Muslims, Islamic Scholars and Islamic banking employees on the current state of the latter industry, both in practical terms and as regards engagement with the nation’s large, but often marginalised Islamic community. The British Government has recently championed the Islamic banking sector and committed to supporting it as a means of addressing financial services needs and consolidating London’s position as the global centre for Islamic investment. The analysis adds to the substantive literature in two principal ways: (i) by contextualising the evidence via the notions of empowerment, engagement and social justice that underpin both the state’s attempts to foster growth and the central tenets of Islam; and (ii) by placing comparison of the opinions of key groups at the heart of the investigation. The findings reveal that while progress has been made, UK-based Muslims see several substantive impediments to access, including the complex terminology of Islamic banking products, the lack of internet banking facilities and branch networks as well as a generalised lack of interest in marketing on the part of the institutions. Whilst some coincidence of perception is evident, the views of bankers are shown to be out of line with those of the other parties in a number of key areas. For example, bankers appear to see less potential in the role of the internet as a medium for spreading awareness than do either potential customers or religious scholars. The paper therefore concludes with a call for multi-party Ijtihad and Qiyas (deductive analogy) that will encourage industrial outreach and, in so doing, support long-term growth.     

Where is the distribution tail threshold? A tale on tail and copulas in financial risk measurement

Estimating the market risk is conditioned by the fat tail of the distribution of returns. But the tail index depends on the threshold of this distribution fat tail. We propose a methodology based on the decomposition of the series into positive outliers, Gaussian central part and negative outliers and uses the latter to estimate this cutoff point. Additionally, from this decomposition, we estimate extreme dependence correlation matrix which is used in the measurement of portfolio risk. For a sample consisting of six assets (Bitcoin, Gold, Brent, Standard&Poor-500, Nasdaq and Real Estate index), we find that our methodology presents better results, in terms of normality and volatility of the tail index, than the Kolmogorov–Smirnov distance, and its unnecessary capital consumption is lower. Also, in the measurement of the risk of a portfolio, the results of our proposal improve those of a t-Student copula and allow us to estimate the extreme dependence and the corresponding indexes avoiding the implicit restrictions of the elliptic and Archimedean copulas.

Can both Bitcoin and gold serve as safe-haven assets? — A comparative analysis based on the NARDL model

This paper uses the nonlinear autoregressive distributed lag (NARDL) model to analyze the different performances of Bitcoin and gold under the impacts of three different uncertainties, namely global economic policy uncertainty (GEPU), US stock market volatility index (VIX) and the CBOE crude oil ETF volatility index (OVX). The results indicate that faced with shocks of different uncertainties, Bitcoin is unable to serve as a safe-haven, while gold can hedge against uncertainties to varying degrees. Moreover, the three types of uncertainties have asymmetric impacts on the prices of Bitcoin and gold respectively. The decrease of uncertainties has a greater impact on Bitcoin price than the increase, while the increase of uncertainties has a greater impact on gold price than the decrease. It suggests that investors are cautious and optimistic about Bitcoin, and gold remains unanimously recognized as the traditional safe-haven.     

Challenges and opportunities in disclosure research—A discussion of ‘the financial reporting environment: Review of the recent literature’

Beyer et al. (2010) review the financial reporting literature related to voluntary and mandatory firm disclosures, and sell-side analyst reports. The discussion summarizes their approach, highlights some of their main conclusions, and presents alternative ideas about promising avenues for future research.     

A Wealth Tax on the Rich to Bring Down Public Debt? Revenue and Distributional Effects of a Capital Levy in Germany

The idea of higher wealth taxes to finance the mounting public debt in the wake of the financial crisis is gaining ground in several OECD countries. We evaluate the revenue and distributional effects of a one‐time capital levy on personal net wealth that is currently on the political agenda in Germany. We use survey data from the German Socio‐Economic Panel (SOEP) and estimate the net wealth distribution at the very top, based on publicly‐available information about very rich Germans. Since net wealth is strongly concentrated, the capital levy could raise substantial revenue, even if relatively high personal allowances are granted. We also analyse the compliance and administrative costs of the capital levy.     

Can differences in the background characteristics of the chairperson–CEO vertical dyad reduce management agency costs?—A perspective Based on the internal configuration of the top management team

We test whether differences in the background characteristics of firms’ chairperson and CEO can reduce management agency costs. We find that when the chairperson is older, has a higher level of education, and has more overseas experience than the CEO, the management agency costs will be lower. A series of robustness tests do not change our conclusions. In further analysis, we find that the negative relationship between the two is more significant for SOEs or firms experiencing fierce market competition. Finally, we also find that the chairman-CEO’s vertical dyad background characteristics differences can help to improve firm performance. Our study provides theoretical and practical implications for companies on how to best configure their top management team.

Abstract

We consider an optimal dynamic control problem for an insurance company with opportunities of proportional reinsurance and investment. The company can purchase proportional reinsurance to reduce its risk level and invest its surplus in a financial market that has a Black-Scholes risky asset and a risk-free asset. When investing in the risk-free asset, three practical borrowing constraints are studied individually: (B1) the borrowing rate is higher than lending (saving) rate, (B2) the dollar amount borrowed is no more than K > 0, and (B3) the proportion of the borrowed amount to the surplus level is no more than k > 0. Under each of the constraints, the objective is to minimize the probability of ruin. Classical stochastic control theory is applied to solve the problem. Specifically, the minimal ruin probability functions are obtained in closed form by solving Hamilton-Jacobi-Bellman (HJB) equations, and their associated optimal reinsurance-investment policies are found by verification techniques.     

Do Repeated Wildfires Change Homebuyers’ Demand for Homes in High-Risk Areas? A Hedonic Analysis of the Short and Long-Term Effects of Repeated Wildfires on House Prices in Southern California

Unlike most hedonic studies that analyze the effects of a one-time event, this paper analyzes the effects of forest fires that are several years apart in a small geographical area. We find that repeated forest fires cause house prices to decrease for houses located near the fires. We test and reject the hypothesis that the house price reduction from one fire is equal to the house price reduction from a second fire. The first fire reduces house prices by about 10%, while the second fire reduces house prices by nearly 23%, a statistically significant difference. The pattern of these results are robust to several alternative econometric specifications.

The accountant will have a central role in saving the planet … really? A reflection on ‘green accounting and green eyeshades twenty years later’

There is widespread but not universal acceptance that organisations should provide ‘accounts’ of not only their financial performance, but also of their social and environmental performance. There have also been various suggestions across time that traditional financial reporting frameworks, albeit with some modification, have relevance to calls for greater corporate accountability. This paper seeks to dismiss such suggestions. For the accounting profession to be able to meaningfully contribute to extending accountability beyond investors, lenders, and creditors (and it undoubtedly serves these interests well) it will need to abandon many core accounting conventions and principles – something that is deemed unlikely to occur – at least in the readers’ lifetime. This paper also highlights the apparent absurdity of using market-based mechanisms (such as cap-and-trade systems for pollutants) to solve social and environmental problems that were effectively caused by ‘the market’. Having questioned the role of the accounting profession in contributing to broad-based corporate accountability, the paper concludes by questioning the role of accounting and business educators in instilling some form of personal social responsibility in the minds of students.

Abstract

We consider the valuation of credit default swaps (CDSs) under an extended version of Merton’s structural model for a firm’s corporate liabilities. In particular, the interest rate process of a money market account, the appreciation rate, and the volatility of the firm’s value have switching dynamics governed by a finite-state Markov chain in continuous time. The states of the Markov chain are deemed to represent the states of an economy. The shift from one economic state to another may be attributed to certain factors that affect the profits or earnings of a firm; examples of such factors include changes in business conditions, corporate decisions, company operations, management strategies, macroeconomic conditions, and business cycles. In this article, the Esscher transform, which is a well-known tool in actuarial science, is employed to determine an equivalent martingale measure for the valuation problem in the incomplete market setting. Systems of coupled partial differential equations (PDEs) satisfied by the real-world and risk-neutral default probabilities are derived. The consequences for the swap rate of a CDS brought about by the regimeswitching effect of the firm’s value are investigated via a numerical example for the case of a two-state Markov chain. We perform sensitivity analyses for the real-world default probability and the swap rate when different model parameters vary. We also investigate the accuracy and efficiency of the PDE approach by comparing the numerical results from the PDE approach to those from the Monte Carlo simulation.     

Optimal time to sell a stock in the Black–Scholes model: comment on ‘Thou shalt buy and hold’, by A. Shiryaev,Z. Xu and X.Y. Zhou

We reconsider the problem of the optimal time to sell a stock studied by Shiryaev et al. (2008 Shiryaev, A, Xu, Z and Zhou, XY. 2008. Thou shalt buy and hold. Quant. Finan., 8: 765–776. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) (following in this issue of Quantitative Finance) using path integral methods. These methods allow us to confirm the results obtained by these authors and extend them to the entire parameter region. We also obtain the full distribution of the time t_m at which the maximum of the price is reached for arbitrary values of the drift.
