Muslim economists have employed the mainstream economics tools to explicate consumption in the Islamic framework. Two of the key limitations of these early works are that they used the Keynesian framework without building micro foundations and they did not model the behaviour in an intertemporal context.
There is considerable debate in Islamic economics literature on what shall be the correct response and attitude towards mainstream economics methodology. There are three varied responses among Islamic economists regarding the issue. The first response is to use the methodology of mainstream economics in Islamic economics as is. The second response is to modify it according to the needs and the context of Islamic framework. The third response is to discard it altogether and devise a new methodological framework from scratch.
This article highlights the points of distinction and compatibility between the Islamic and mainstream economics framework. The distinction comes in the decision horizon and the addition of moral filters on the choice set. The difference also appears explicit when one looks at the encouragement and incentive structure for pure altruism in a two-worldly Islamic framework. The distinction is even deeper in values whereby the Islamic framework encourages contentment, pure altruism and self-less behaviour while the mainstream economics framework is at best neutral between the moral content of economic choices.
This article looks at some of the descriptive and prescriptive teachings of Al-Quran and Sunnah (Ways of Prophet Muhammad [pbuh]) on consumption and spending behaviour.
