Effect of transparency on decision making the case of Euphrates and tigris river water use

Transparency is an important factor in decision making because availability of information aids in clarity of thought. This paper focuses on information transparency and examines its impact on decision making through a case study of river water use in the Euphrates and the Tigris, Iraq. To conduct a detailed discussion on the role of transparency, other related concepts, namely uncertainty, indeterminacy, and instability in players' decisions, are defined in the framework of a game theoretical model, and the effects of them on the results of decision making are analyzed.
