I'm looking for a book (or similar: journal review article, chapter in
a book, etc.) on modeling commodity prices and
price-based indexes. 
More specifically, I want to learn how to
specify stochastic models
(both parametric and non-parametric) that
replicate as closely as
possible the statistical properties of the
past decade's prices time
series.




I am not interested in general books on statistics or time
series
analysis without specific and extensive discussions on the
problem of
modeling price fluctuations.

Although I expect there are many books and review articles on
this
topic, I have had little success in my search; I suspect I
just
haven't hit on the right keywords for my search.
