This paper studies how the strength of social ties are affected by the geographical location of other individuals and their social capital. We characterize the equilibrium in terms of both social interactions and social capital. We show that lower travel costs increase not only the interaction...

This study quantifies the spillover effects of PM2.5 emissions on emergency room visits due to respiratory diseases in Chile. We use several spatial panel methods and models controlling also for the potential endogeneity of air quality. Our estimates show that the spillover effects are downward...

Cross-border, transnational regional development in the Rhine-Alpine EU transport corridor represents an ongoing challenge. With 18 partners from five countries, the Rhine-Neckar regional association (Verband Region Rhein-Neckar, VRRN) therefore initiated an EU-funded project along the corridor...

In order to allocate resources and formulate policies effectively, governments and enterprises often need accurate geographical information on profit-seeking enterprises. This study explores the impact of local fiscal expenditure and environmental regulation on the number of profit-seeking...

This paper develops a nonlinear spatial dynamic panel data model, with one particularly interesting application to a structural interaction model for share data. To account for effects from popular units, the spatial weights matrices in our model can allow for dominant units, with unbounded...
