We provide econometric evidence that relative per capita GDP and relative unemployment rates are the main determinants of migration flows across Italian regions from 1970 to 2002. The empirical analysis is based on an accurate study of the dynamic properties of the series. In fact, we deal with...

This paper investigates the relationship between intra-industry trade (IIT) and immigration flows using a gravity model for the period 2000-2010 between Portugal and European Union’s Member States (EU-27). The present study uses the methodology of Kandogan (2003) for separating IIT into its...

With the rise of the knowledge economy, delivering sound innovation policies requires a thorough understanding of how knowledge is produced and diffused. This paper takes a step to analyze a new form of globalization, the so-called system of Global Innovation Networks (GINs), to shed light on...

This paper aims to explore how the competitiveness of the EU economy, here captured by export dynamics over the medium run (1996-2007), has been affected by environmental regulation both on the public and private sector side. The strong and weak versions of the Porter hypothesis are tested by...

This paper analyses the contribution to the creation of a culturally diverse Sydney landscape by ethnic communities following the arrival of over a million and half non-English speaking settlers since 1948. Through fragmented collective actions, around 450 communal places were established to...

We examine how three different communication processes operating through social networks are affected by homophily - the tendency of individuals to associate with others similar to themselves. Homophily has no effect if messages are broadcast or sent via shortest paths; only connection density...
