كفاءة و عدالة توزيع الدخل-الشرط الضروري و الشرط الكافي : الاقتصاد الإسلامي أنموذجا

الملخص EN

Economic efficiency and justice in distribution of income is a sensitive economic, social and political topic at the level of formulation of economic theories.

Since the first formulations, mathematical sciences have been used as tools of analysis to arrive at convincing results.

This paper addresses the topic of efficiency and justice in income distribution through a basic issue; namely comprehensive prosperity or happiness via its two main dimensions: the necessary condition and the sufficient condition.

It then demonstrates the foundational settings through logic, philosophy and mathematics.

It then attends to the modern theoretical formulations on the topic and the ongoing controversy concerning the relation of the research with the principle of benefit on the one hand and the issues of right and good on the other hand.

It then presents the Islamic alternative.

The study concludes that there are two responsibilities that fall upon the sector of the economy having more benefits, viz.

funding the incomes of the sector having fewer benefits through alms (zakah) and other financial impositions and the voluntary ones to make their incomes reach the level of sufficient income.

The other one is to fund investment through their savings.

This is an issue of double impact on the total economic activity.
