We study the estimation of the additive components in additive regression models, based on the weighted sample average of regression surface, for stationary [alpha]-mixing processes. Explicit expression of this method makes possible a fast computation and allows an asymptotic analysis. The...

The regional distribution of labour productivity in Western Europe is characterised by a Core-Periphery spatial pattern: high (low) productivity regions are in a proximate relationship with other high (low) productivity regions. Over the period 1980 to 2003, intra-distribution dynamics has...
