Integrating gravity: the role of scale invariance in gravity models of spatial interactions and trade (English)

Abstract

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 constrain... See More +
