Integrating Gravity: The Role of Scale Invariance in Gravity Models of Spatial Interactions and Trade

This paper revisits the ubiquitous bi-proportional gravity model and investigates the reasons why different theoretical frameworks may lead to the same empirical formula. The generic gravity equation possesses scale invariance symmetries that const...
