RT Journal Article SR Electronic T1 Precipitation Modeling and Contract Valuation JF The Journal of Alternative Investments FD Institutional Investor Journals SP 93 OP 99 DO 10.3905/jai.2004.439656 VO 7 IS 2 A1 Melanie Cao A1 Anlong Li A1 Jason Z Wei YR 2004 UL https://pm-research.com/content/7/2/93.abstract AB This article has two objectives. First, it describes the market for precipitation derivatives and provides examples of applications of such contracts. Second, it proposes, estimates, and compares several models for precipitation. Based on the data for Chicago Midway Airport (1950–2003), we find that a mixture of exponentials and kernel density provide a better fit than a gamma distribution. A valuation example is also presented.
