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...

Cultural diversity is a complex and multi-faceted concept. Commonly used quantitative measures of the spatial distribution of culturally-defined groups 'such as segregation, isolation or concentration indexes' are often only capable of identifying just one aspect of this distribution. The...

The rapidly increasing dissemination of scientific results exhibits features of complex systems and brings also to light (seemingly) inconsistencies among research findings. At the same time, there is a fast growing interest in comparative studies and related research tools such as meta-analysis...

This paper positions time in the centre of spatial economic analysis, with a particular view on transport behaviour. The conventional assumption is that there is for most people in our society a constant travel time budget, so that higher speeds tend to lead to longer travel distance....

We propose a new Markov switching model with time varying probabilities for the transitions. The novelty of our model is that the transition probabilities evolve over time by means of an observation driven model. The innovation of the time varying probability is generated by the score of the...
