We study whether and when parameter-driven time-varying parameter models lead to forecasting gains over observation-driven models. We consider dynamic count, intensity, duration, volatility and copula models, including new specifications that have not been studied earlier in the literature. In...

We propose a new methodology for designing flexible proposal densities for the joint posterior density of parameters and states in a nonlinear non-Gaussian state space model. We show that a highly efficient Bayesian procedure emerges when these proposal densities are used in an independent...

We perform a test of the inflation hedging properties of commodities on the longest data series ever used for this purpose. We apply wavelet analysis to commodity prices and inflation data from the United Kingdom for the years 1265 through 2017, to detect co-movement across different times and...
