Spatial filtering and eigenvector stability : Space-time model for German unemployment data

Patuelli, Roberto ; Griffith, Daniel A. ; Tiefelsdorf, Michael ; Nijkamp, Peter

Regions, independent of their geographic level of aggregation, are known to be interrelated partly due to their relative locations. Similar economic performance among regions can be attributed to proximity. Consequently, a proper understanding, and accounting, of spatial liaisons is needed in order to effectively forecast regional economic variables. Several spatial econometric techniques are...

A spatial-dependence continuous-time model for regional unemployment in Germany

Oud, Johan H.L. ; Folmer, Henk ; Patuelli, Roberto ; Nijkamp, Peter

This paper analyzes patterns of regional labour market development in Germany over the period 2000-2003 by means of a spatial-dependence continuous-time model. (Spatial) panel data are routinely modelled in discrete time. However, there are compelling arguments for continuous time modelling of (spatial) panel data. Particularly, most social processes evolve in continuous time such that analysis...

Poolability and aggregation problems of regional innovation data : an application to nanomaterial patenting

Patuelli, Roberto ; Vaona, Andrea ; Grimpe, Christoph

Research and development (R&D) in the field of nanomaterials is expected to be a major driver of innovation and economic growth. In this respect, many countries, as national systems of innovation, have established support programs offering subsidies for industry- and government-funded R&D. Consequently, it is of great interest to understand which factors facilitate the creation of new...

Knowledge production in nanomaterials : An application of spatial filtering to regional systems of innovation

Grimpe, Christoph ; Patuelli, Roberto

Nanomaterials are seen as a key technology for the 21st Century, and much is expected of them in terms of innovation and economic growth. They could open the way to many radically new applications, which would form the basis of innovative products. In this context, it seems all the more important for regions to put their own innovation systems in place, and to ensure that they offer a suitable...
