A Critique of Pareto Efficiency and an Introduction to the Maqasid al-Shari’ah

pareto efficiency is a concept in economics that describes a situation where no one can be made better off without making someone else worse off. It means that the resources in an economy are allocated in the most efficient way possible, and there is no waste or inefficiency. Pareto efficiency is named after Vilfredo Pareto, an Italian economist who studied economic efficiency and income distribution. Pareto efficiency can be illustrated by a production possibility frontier (PPF), which is a curve that shows the maximum possible output of two goods or services using the available resources. Any point on the PPF represents a Pareto efficient allocation, where it is impossible to produce more of one good without producing less of the other. Any point inside the PPF represents a Pareto inefficient allocation, where some resources are not used or used inefficiently. Any point outside the PFF represents an unattainable allocation, where the resources are not enough to produce that level of output.

Pareto efficiency may seem logical and value-free, but it is not. It is based on the secularist worldview of the prevailing systems, which ignores the moral and spiritual dimensions of human well-being. Pareto efficiency also grants a veto power to anyone opposed to change, even if that change would benefit the majority of the society. Pareto efficiency does not take into account the distributional aspects of welfare, and it may justify the status quo of inequalities and injustices. 

The maqasid al-Shari’ah are the objectives or purposes of the Islamic teachings, which aim at realizing human well-being in this world and the hereafter. The maqasid al-Shari’ah include everything that is necessary to preserve and enrich faith, life, intellect, posterity and wealth. The sources of the maqasid al-Shari’ah are the Qur’an and the Sunnah, which are the primary sources of Islamic law and guidance. The methods of deriving the maqasid al-Shari’ah are based on rational interpretation and deduction, using principles such as analogy, public interest, necessity and custom.

Islam recognizes that there are different perspectives and approaches to human problems, and that there is room for dialogue and cooperation among them. Islam also respects the freedom and dignity of all human beings, regardless of their faith or background. However, Islam also offers a comprehensive and coherent framework for human well-being, based on its own concepts of falah (success) and hayat tayyibah (good life), which give utmost importance to brotherhood and socio-economic justice. Islam also provides a moral filter for allocation and distribution of resources, a motivating system for economic effort, and a socio-economic restructuring to ensure efficiency and equity. Islam thus offers a viable alternative to the unsuccessful systems that have failed to realize their professed goals.
