As for modelling, the trend has been either to provide :
* a model describing at the same time, nominal rates, real rates and inflation and representing the inflation as the exchange rate between nominal and real rates. The first type of model along these lines has been the one of Jarrow and Yildirim.
* a market model that represents the inflation like a real asset and uses similar ideas as the one of BGM to represent the inflation returns. The first type of model along these lines has been the one of Belgrade, Benhamou, Koehler that is commercially available in Pricing Partners modelling suite. Another more advanced version has been the one of Fabio Mercurio and Nicola Moreni
