Despite the gravity equation's empirical success in "explaining" trade flows, the model's predictive potential has been inhibited by an absence of strong theoretical foundations. A general equilibrium world trade model is presented from which a gravity equation is derived by making certain assumptions, including perfect international product substitutability. If, however, trade flows are differentiated by origin as evidence suggests, the typical gravity equation is misspecified, omitting… Expand

Review of Gravity Model Derivations
The gravity model of international trade flows is a common approach to modeling bilateral trade flows. But it is criticized on the ground of weak theoretical base and poor micro-foundation. TheExpand
The Gravity Equation in International Trade
This chapter offers a selective survey of the gravity equation (GE) in international trade. This equation started in the Sixties as a purely empirical proposition to explain bilateral trade flows,Expand
Recalculating Gravity: A Correction of Bergstrand’s 1985 Frictionless Case · Econ Journal Watch : international economics, trade, gravity model
Jeffrey Bergstrand (1985) derives a theoretical gravity equation for bilateral international trade flows focusing on the role of prices. The gravity equation has served as the basis for thousands ofExpand
An extended gravity model with substitution applied to international trade
The traditional gravity model has been applied many times to international trade flows, especially in order to analyze trade creation and trade diversion. However, there are two fundamentalExpand
Undertstanding the Home Market Effect and the Gravity Equation: the Role of Differentiating Goods
This paper argues that the theoretical foundations for the gravity equation are general, while the empirical performance of the gravity equation is specific to the type of goods examined. MostExpand
Disaggregated trade flows and the “missing globalization puzzle”
This study analyzes the stability of the distance coefficient values over time in the generalized gravity equation of Bergstrand (1989) using both aggregate and disaggregated trade flows among 22Expand

This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and rich substitution patterns across goods. InExpand
