This paper introduces cultural gravity as a new concept for analyzing socio-economic disparities among immigrants. It tests the existence of cultural gravity effects on the geographic concentration and human capital productivity of immigrants. Using cultural distance as a proxy for the local...

Using quarterly data of 58 countries, this paper provides empirical evidence that mobile phone diffusion from 2007 to 2009 is positively influenced by international network effects. Direct and indirect network effects are a result of the international standadization of telecommunication...

The purpose of this paper is to illuminate the geographical diffusion of photovoltaic installations in Germany quantitatively and to test if preexisting photovoltaic systems stimulate further installations nearby; thus we investigate to which extent knowledge flows depend on geographic...

This paper aims to identify the contribution of knowledge capital and its determinant - human capital - to total factor productivity differences among regions within a regression framework in general and the impact of their spillovers on regional total factor productivity in particular. The...

Regarding context conditions and the role of territories on competitiveness and innovation, clusters have become progressively a spreading phenomenon all around the world. Recently, the importance of clusters has been mixed with the concept of smart specialization, a territorial development...

This paper proposes a fixed-effect panel methodology that enables us to simultaneously take into account both TFP convergence and the traditional neoclassical-type of convergence. We analyse a sample of 199 European regions between 1985 and 2006 and find the absence of an overall process of TFP...

Cloud computing is widely seen as a new source of innovation as well as a driving factor of productivity improvements of firms. This paper analyses the determinants of cloud computing adoption in general as well as for specific deployment (Public vs. Private) and service models (SaaS, IaaS,...

Applications such as iMessage, KakaoTalk, LINE, Signal, Skype, Snapchat, Threema, Viber, WhatsApp and WeChat have become an increasingly popular means of personal and business interaction. Surprisingly little academic effort has gone into understanding the nature and origin of these...

We study spatio-temporal variation of peer effects in rooftop photovoltaics adoption of households. Our investigation employs locational data on potential adopters and a geocoded data set of all grid-connected photovoltaic systems set up in Germany through 2010. The detailed locational data...
