ISLAMIC BANKING AND FINANCE: RECENT EMPIRICAL LITERATURE AND DIRECTIONS FOR FUTURE RESEARCH

This paper examines the recent empirical literature in Islamic banking and finance, highlights the main findings and provides a guide for future research. Early studies focus on the efficiency, production technology and general performance features of Islamic versus conventional banks, whereas more recent work looks at profit‐sharing and loss‐bearing behaviour, competition, risks as well as other dimensions such as small business lending and financial inclusion. Apart from key exceptions, the empirical literature suggests no major differences between Islamic and conventional banks in terms of their efficiency, competition and risk features (although small Islamic banks are found to be less risky than their conventional counterparts). There is some evidence that Islamic finance aids inclusion and financial sector development. Results from the empirical finance literature, dominated by studies that focus on the risk/return features of mutual funds, finds that Islamic funds perform as well, if not better, than conventional funds – there is little evidence that they perform worse than standard industry benchmarks.     

The Impact of Single Stock Futures on Market Efficiency and Volatility: A Dynamic CAPM Approach

The concerns regarding regulations of futures markets and their destabilizing ability are unresolved in both developed and developing markets. Following stringent regulations of single stock futures (SSFs) for resumption episode after financial crises, this study addresses this concern and investigates the destabilizing impact of SSFs on the underlying stocks in an emerging economy using data of companies listed in the Karachi Stock Exchange between 1999 and 2008. Specifically, the study explores whether SSFs have caused a simultaneous increase in the volatility and operational efficiency of their underlying spot market counterparts. The results reported in the study show that the introduction of SSFs has no significant impact on market efficiency and volatility of SSFs underlying stocks and non-SSFs stocks. The results affirm that SSFs have, at least, no destabilizing impact on the underlying stocks.     

Lockup Agreements and Survival of UK IPOs

This paper examines the role of lockup agreements on the survival of 580 UK Initial Public Offerings (IPOs) during the period of 1990–2011. Our accelerated failure time (AFT) survival model shows a statistically and economically significant effect of lockup length on the post‐IPO survival. A 12 month increase in median lockup period increases the (median) survival time by 27%. Furthermore, the failure rates for IPOs with longer lockups are consistently lower than the failure rates for IPOs with shorter lockups regardless of delisting reasons. The results are robust to choice of different survival estimation models, heterogeneity, clustering, and alternative specification of variables. Our results highlight the importance of lockup characteristics on the subsequent survival of newly listed firms and inform recent debate regarding alleged short‐termism in the UK equity market.     

A conceptual framework for intra-company technology transfer: cases of leveraging production process innovations across MNEs

Multinational enterprises (MNEs) strive to commercialise their knowledge base globally by mobilising their technological competencies, transferring them across organisational boundaries, and selling the resulting systems, products, processes, and services worldwide. However, co-operation within MNEs still leaves potential for improvement, because intra-company transfers of technology as modes of corporate expansion and conquest of new international markets seldom work efficiently. Academic literature has not adequately addressed this important issue. Based on six case studies from MNEs, this paper highlights the challenges of intra-company technology transfer by examining exemplary cases of production process-related technology transfers. It establishes a conceptual framework model for intra-company technology transfers and identifies important success factors.     

Pollution Taxes When Firms Choose Technologies

We consider the properties of a pollution tax when the regulated firm has a discrete choice of technologies with which to reduce pollution. The firm's technology choice makes possible two sequences of play: the traditional one in which the regulator moves first, committing to a tax rate before the firm adopts a technology, and an alternative one in which the firm moves first by adopting a technology. We find that a range of pollution levels, including possibly the first-best one, are unattainable when the regulator moves first. The regulator may be better able to achieve the first-best outcome when the firm moves first.     

Weather Effects on Stock Returns and Volatility in South Asian Markets

We study the effect of mood-proxy variables on index returns and volatility in six South Asian markets. Our mood-proxy variables include six weather (temperature, humidity, cloud cover, air pressure, visibility, and wind speed), three weather indicator variables (fog, thunder storm and rain or drizzle) and two biorhythmic variables (SAD and lunar phases). We adopt a robust approach and attempt to select the best parsimonious econometric model for each market. Our findings suggest that mood-proxy variables have some convincing influences in South Asian capital markets. In some instances, these variables are influencing returns while in other instances they are influencing volatility.     

Can position limits restrain ‘rogue’ trading?

This paper studies the imposition of position limits on commodity futures from the perspective of curbing excessive speculation and thus manipulation. We present a simple general equilibrium model in a static rational expectations framework and agent heterogeneity to illustrate that excessive speculation serves to enrich other agents at the expense of the speculator. Position limits, on the contrary, are not only superfluous, but also counter-productive, as they exacerbate market power and lead to a deterioration in efficiency. Position limits not only reduce social welfare but also cannot restrain market manipulation.     

The Desirability of forgiveness in regulatory enforcement

I present a model that explains two common features of regulatory enforcement: selective forgiveness of noncompliance, and the collection of information on a firm’s compliance activities and not just its compliance status. I show that forgiving noncompliance is optimal if the information on a firm’s compliance activities constitutes sufficiently strong evidence of the firm having exerted a high level of compliance effort. The key benefit of forgiving noncompliance is a reduction in the probability with which the firm needs to be monitored.     

Analysis of School Enrollment in Ghana: A Sequential Approach

In this paper, we depart from the standard way of analyzing school enrollment by accounting explicitly for educational selectivity in order to examine the determinants of child school enrollment in Ghana. Using data from the Ghana Living Standard Survey round 6 (GLSS 6), we estimate a three‐step sequential logit model for the determinants of secondary school enrollment and its dependence on completing primary school. We find that family resources such as parental education, household income and the gender of the head of the household play a role in households' child schooling decisions. Educated parents are relatively more likely to enroll their children in primary school and keep them in school until they complete primary education. As well, we show that educated parents do not promote a gender‐biased investment in the schooling of children at the primary level. While household welfare does not influence children's entry into primary school importantly, their completion of primary school depends on household welfare. The study sheds more light on the pro‐male bias phenomenon regarding entry into primary school and primary school completion. Policies to promote the achievement of Sustainable Development Goal 4 in Ghana must be grade sensitive.
