What is the Gravity Model of Trade? by Aaron Schnoor
The basic model for trade between two countries (iand j) takes the form of. Fij=G⋅MiMjDij.{\displaystyle F_{ij}=G\cdot {\frac {M_{i}M_{j}}{D_{ij}}}.} In this formula G is a constant, F stands for trade flow, D stands for the distance and M stands for the economic dimensions of the countries that are being measured. See more The gravity model of international trade in international economics is a model that, in its traditional form, predicts bilateral trade flows based on the economic sizes and distance between two units.
