WebGravity models link trade flows with economic size and inversely with trade costs. Hence, gravity models can capture patterns in international trade and production. Policy researchers can use them to estimate the trade impacts of various trade-related policies, from traditional tariffs to new “behind-the-border” measures. WebMay 1, 2024 · The gravity model, initially made popular by the cartographer E.G. Ravenstein in 1889, was originated to study the impact of country size and location on migration patterns.

The gravity model estimates the pattern of international trade. While the model’s basic form consists of factors that have more to do with geography and spatiality, the gravity model has been used to test hypotheses rooted in purer economic theories of trade as well.
