We prove the uniqueness of linear i.i.d. representations of heavy-tailed processes whose distribution belongs to the domain of attraction of an $\alpha$-stable law, with $\alpha2$. This shows the possibility to identify nonparametrically both the sequence of two-sided moving average coefficients...

This paper proposes a modified present-value model that takes into account the fact that movements in the price-rent ratio for housing may not be mean-reverting. Our approach decomposes the price-rent ratio into expected real rent growth, expected housing return and a non-present-value (NPV)...

I discuss models which allow the local level model, which rationalised exponentially weighted moving averages, to have a time-varying signal/noise ratio. I call this a martingale component model. This makes the rate of discounting of data local. I show how to handle such models effectively using...
