Technology spillover and TFP growth: A spatial Durbin model

2016

Beginning with a model in which technological progress is reflected by product variety, we provide a structural approach to estimate technology spillovers allowing for spatial interdependencies. To this end, we first present a theoretical model of TFP growth by decomposing TFP into quality and variety components. We address the quality component by introducing a country׳s distance to the technological frontier. Quality is assumed to be a negative function of the technological gap of country i with respect to its own technological frontier. This technological threshold is defined as the geometric means of knowledge levels in all countries. We deal with the variety component by using R&D expe…

Neighbourhood effects and determinants of population changes in Italy: a spatial perspective

2023

Population trends in Italy are strongly spatially differentiated, with some munic- ipalities showing a systematic loss of population, and others showing an equally continuous demographic increase. Here, we focus our attention on the spatial dimension of population change, looking at how different socio-economic and demographic dimensions affect population changes, as well as their spatial effects. After performing a preliminary descriptive analysis of the trends of population growth and decline in Italy over the last 40 years and the relevant demographic components, we used a spatial Durbin model (SDM) to investigate the potential existence of a diffusion process and the determinants of the…
