Models of Hedging the Price Risk of Raw Materials: A Literature Review

Abstract

Mandeng Ma Ntamack Jules

This article highlights a set of model risk management in commodity prices since the pioneering work of Yamey in 1951 to the most resents contributions. Only hear were taken into account theoretical models and in a nonexhaustive way, but grouped into three streams of reflection (the traditional models, modern approaches and recent contributions). The models place particular emphasis on the behaviour of suppliers of raw materials to the risk of price and seek ultimately to stabilize commodity prices turn an acceptable average. But the results obtained through various tests of these models show the apparent ineffectiveness of these and give reason to the market. This confirms the theory of efficient markets, in the sense that no one can beat it.
