Webto examination of the gravity equation itself. The Gravity Equation Theoretical Foundations Although aspersions have been cast on the respectability of the gravity model of trade in the past, by now its theoretical pedigree has been proven. Earlier work surveyed by Deardorff (1984, 503-06) provided a partial foundation for the approach. 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. ...

In contrast with the usual specification, our model allows for the realistic assumption of asymmetry in mutual ...

This paper shows that the gravity model may merit continued development and use. Section I develops the simplest linear expenditure model, which produces an equation like (1) but with the last ... WebThe simple gravity equation explains a great deal about the data on bilateral trade flows, and is consistent with several theoretical models of trade. We argue that alternative …
Webgravity rceof = In trade, we replace the force of gravity with the value of bilateral trade and the masses M 1 and M 2 with the trade partners’ GDPs (in physics G is the gravitational constant). Strange as it may seem, this fits the data very well; an R-squared of 0.7 on cross-section data is par for the course. Yet despite its goodness-of-
