WebMar 21, 2024 · According to Öberg (Citation 1997), the spatial gravity model is one of the strongest theories in applied geography. The model is based on the works of Ravenstein (Citation 1885), who stated that the volume of migration is inversely related to distance. WebThomas Chaney. The gravity equation in international trade is one of the most robust empirical finding in economics: bilateral trade between two countries is proportional to size, measured by GDP, and inversely proportional to the geographic distance between them. While the role of size is well understood, the role of distance remains a mystery.
