The impact of Islamic accounting standards on information asymmetry

Abstract

Purpose The purpose of this paper is to investigate whether disclosure as required by Islamic Financial Service Board Standard No. 4 (IFSB-4) influences information asymmetry among investors in the Gulf Cooperation Council (GCC) member countries. In addition, the paper investigates whether the influence of IFSB-4 on information asymmetry varies between Islamic and conventional financial institutions. Design/methodology/approach The paper tests the hypotheses using a sample of firms listed in the GCC over a period of 2000-2013. Ordinary least square regression and fixed-effects estimation techniques are applied to test the hypotheses. Findings The findings reveal that information asymmetry among investors is lower after the implementation of IFSB-4 than before, indicating that the standard has increased transparency. The results also reveal that information asymmetry after the implementation of IFSB-4 is lower for Islamic than for conventional financial institutions. This suggests that IFAB-4 promotes more transparency for Islamic than conventional institutions. Research limitations/implications Owing to data availability, we were unable to use other proxies of information asymmetry, e.g. bid-ask spreads, and the level of disclosure, e.g. self-constructed disclosure index. Practical implications The paper concludes that disclosures under IFAB-4 reduce information asymmetry among investors. In this context, this study increases the awareness of standard setters academics investors regulators and many other stakeholders about the economic consequences of disclosure standards in the region. Originality/value This study takes a first step to fill evident gaps in the literature by investigating the influences of disclosure standard on information asymmetry in a unique setting that is often ignored by accounting researchers, which helps to widen our knowledge on accounting practices across the globe.

Information Asymmetry, Ownership Structure and Cost of Equity Capital: The Formation for Open Innovation

“…According to our expectations, the higher the voltrade, the higher the cost of equity capital. The results of this study are in line with the studies of [3,46]. We found a negative relationship between price non-synchronization (PNSY) and cost of equity capital in our study.…”

“…First is VOLTRADE. Following [46] we used VOLTRADE as a proxy for information asymmetry. The higher the trading volume, the lower the information asymmetry.…”

The effects of corporate disclosure on firm value and firm performance: evidence from Turkey

“…Early studies also pointed that disclosure channel is an effective way to reduce information asymmetry between managers and information users (Healy and Palepu, 2001; Brown and Hillegeist, 2007; Tessema et al , 2017; Liu, 2015). Especially, when there is information asymmetry between firms and investors, the relationship between disclosure and information asymmetry was found to be more pronouncedly negative (Brown and Hillegeist, 2007).…”

Sharia governance standards and the role of AAOIFI: a comprehensive literature review and future research agenda

“…Islamic accounting can be defined as “the accounting framework which plans to provide the accounting information, clients data and financial reports to the various stakeholders as per the principles laid down by the Sharia” (Atmeh and Maali, 2017; Siswantoro, 2018; Tessema et al , 2017). Early studies focused on the need for the Islamic accounting and need for the Sharia standards for the Islamic financial institutions (Mohammed et al , 2019; Mohammed Sarea and Mohd Hanefah, 2013).…”
