Built to last: population aging and long run development in metropolitan Europe
The paper examines the role of demography on the growth perspectives of European metropolitan areas. Our findings are in support of the key role played by the demographic structure of the population in determining the economic prospects of European cities. Regions and cities with higher levels of dependency ratios are found to show lower growth rates, in the long run. This evidence supports ...

Impact of logistics performance on world economic growth (2007–2012)
This research proposes a global aggregate production function in dynamic terms which captures the contribution of logistics performance to world economic growth. The well–known model of Mankiw et al. (1992) is used, incorporating the logistics performance index as an explicative production factor, with good results. The production function is estimated empirically for the world's countries with ...

In-house R&D, technology purchase and innovation: empirical evidences from Chinese hi-tech industries, 1995–2004
We empirically estimated the effect of three types of investment in acquiring technological knowledge (in-house R&D, importing foreign technology and purchasing domestic technology) on the innovation output of Chinese firms in four hi-tech industries. These investments on technology are assumed to generate different types of knowledge, which in turn contribute to the enhancement of the ...
