In this paper, we perform a non-linear assessment of Islamic rate - conventional rate relations for the case of Malaysia. Using monthly data covering the period January 1999 to November 2016, we find strong evidence supporting non-linear reactions of the Islamic investment rates to conventional rates in the long run and/or short-run for all matched maturities. More precisely, the Islamic investment rates exhibit faster upward movement (slower downward movement) in responses to conventional deposit rate increases (decreases). The asymmetric pricing behaviour of Islamic banks however tends to weaken as maturity lengthens. Accordingly, we infer that Islamic banks do not rigidly peg their investment deposit rates to conventional deposit rates as some have claimed in questioning the Islamicity of Islamic banks.

The purpose of this paper is to use Ferrell and Gresham (1985) contingency model to examine the impact of situational factors on decision-making behaviour related to ethical issues of Islamic banking practitioners. A total of 262 samples are collected from Islamic banking practitioners in the United Arab Emirates (UAE) and data analysis is conducted using structural equation modelling (SEM) with a confirmatory approach. The empirical findings indicate that decision-making behaviour related to ethical issues of Islamic banking practitioners is significantly influenced in the process of interacting with persons who are part of the organisation, and these influences are determined by the intra-organisational distance and legitimate authority between the individuals and the focal person. Further, it is also empirically verified that decision-making behaviour related to ethical issues of Islamic banking practitioners is significantly influenced by the presence and/or absence of the opportunity factors such as corporate policies, professional codes of ethics and rewards/punishment system that prevails in the organisation.

Even though large banks could imply large risks and heightened vulnerability for a country's macroeconomy, the presence of many small banks with similar behavior such as Islamic banks could also cause systemic risks. This article makes an initial attempt to investigate the impact of bank size on banking performance. Our study spans 12 emerging countries with dual banking systems and applies two-step dynamic system GMM estimator. The results show that size really does matter in the banking industry, and its impact on performance tends to be non-linear with a trade-off between profitability and efficiency. Comparing conventional with Islamic banks, we find that bank size has almost the same impact on the performance of both types of banks.
