Contribution of mathematical models to Islamic economic theory: a survey

Purpose - The purpose of the study is to explore contributions made in Islamic economics methodology, particularly in the use of mathematical models used to build Islamic economic theories. Design/methodology/approach - The methodology adopted is a survey by means of literature review. Findings - Overuse of mathematical models in economics has it apparent weakness in simplifying complex realities and use of impracticable assumptions. But, that notwithstanding, they have a role to play in the development of Islamic economics. Empirical analysis in Islamic economics has weaknesses, including the very fact that moral phenomenon in Islamic economics is difficult to quantify, but its contribution, just like mathematics, is needed to develop the field. Islamic economics adopt mathematical models that do not cause obstacles in achieving the aim of Islamic economics, which is Falah. Where it is harmful, it is discarded. Islamic economics has yet to have a universally accepted research methodology; instead, numerous methodologies are used today. The poor use of mathematics in Islamic economics by new researchers, among other factors, may be due to young researchers’ poor background in mathematics. Originality/value - The paper is unique in looking at the topic of Islamic economic methodology from the angle of application of mathematical models.
