Property indices : Extrapolation of the IPD Japan Capital Growth Index

Abstract: The aim of this work is to extrapolate the IPD Japan Capital Growth index series historically back to the early 1980’s. Using existing, long-running, macro-economic and property-related time series as inputs, we will try to set up a statistical model which can extrapolate the existing eight-year track record back for as many years as statistically significant. Our aim is to set up a model which allows us to produce a historical real estate capital growth series going back for 15 to 20 year.
