Annotation This study aims to make a comprehensive and rigorous policy-theoretic study of Islamic economic co-operation in contemporary perspectives. The principles of Islamic economic theory are rigorously applied to the models, quantitative aspects and analysis of issues relating to Islamic development co-operation. Comparative perspectives of the theory of international economics and development economics are integrated. Critical issues on development financing facing the developing economies in general and the significant proportionate representation of the Islamic economic region in this, are also examined. Finally, the potential of Islamic economic co-operation in the South-South context and the North-South context are studied.
