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.
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.
