Gravity model of trade equation
WebAccording to the gravity model, trade between any two countries is a function of each country's gross domestic product, the distance between them, and possibly other variables that reflect the costs of trade between them. We start from a standard gravity equation that incorporates variables for geographical proximity, common language, trade ... WebGravity equation An estimated equation of the gravity model. Gravity model A model of bilateral trade flows similar to the law of gravity in physics: T ij = AY i Y j /D ij, where T ij is exports from country i to country j, Y i,Y j are their national incomes, D ij is the distance between them, and A is a constant. Other constants as exponents ...

In a world without trade frictions, a simple gravity relationship is given by … WebJan 1, 2014 · The gravity equation is sometimes disparaged on the grounds that any model of trade should exhibit size effects for the exporter and importer. What these figures and regression results show is that the size relationship takes a relatively precise form—one that is predicted by most, but not all, models.
