TOWARDS AN OBJECTIVE MEASURE OF GHARAR IN EXCHANGE

This paper develops a framework for analyzing gharar based on economic aspects of game theory. The framework is consistent with Shari’ah maxims as well as individual gharar transactions widely studied in classical fiqh resources. In addition, the framework brings insights into explaining different fiqhi positions on controversial gharar contracts. When extended to contemporary practices, the measure helps understanding the logic of instrument design, and where violation of Islamic rules exactly lies. The moral, ethical, and social aspects of this framework show the deep consistency between Islamic rules of exchange and general Islamic principles of human behavior.
