The interaction matrix, or spatial weight matrix, is the fundamental tool to model cross-sectional interdependence between observations in spatial econometric models. However, it is most of the time not derived from theory, as it should be ideally, but chosen on an ad hoc basis. In this paper,...

L'objectif de cet article est d'introduire des externalités spatiales dans le modèle de croissance de Solow afin de tenir compte de l'interdépendance géographique des régions. Ces externalités sont générées par le stock de capital accumulé par les régions voisines. Par conséquent,...

We explore the role of financial development to explain the negative correlation between capital inflows and productivity catch-up. Evidence shows that countries with higher productivity growth rates export capital while countries with lower productivity growth rates receive positive capital...

The aim of this paper is to analyze the theoretical and econometric implications of omitting spatial dependence in the Mankiw, Romer, and Weil (1992) model. Indeed, the international distribution of income levels and growth rates suggests the existence of large international disparities, and...
