Gravity with Gravitas: A Solution to the Border Puzzle

Abstract: Gravity equations have been widely used to infer trade flow effects of various institutional arrangements. We show that estimated gravity equations do not have a theoretical foundation. This implies both that estimation suffers from omitted variables bias and that comparative statics analysis is unfounded. We develop a method that (i) consistently and efficiently estimates a theoretical gravity equation and (ii) correctly calculates the comparative statics of trade frictions. We apply the method to solve the f… Show more

“…Some authors (Frankel and Wei 1993;Frankel 1997b;Anderson and van Wincoop 2003) have proposed using the NLS method in estimating the gravity equation: this function gives more weight to observations where exp(Xb ) is large, so that countries with larger S i and M j for instance, get more weight. There is economic intuition for this weighting scheme, as countries with higher GDP tend to report more accurately and therefore get more weight in estimating the model.…”

“…This dummy clarifies the effective distance among two countries (i and j) which may engage in large volumes of border trade (McCallum, 1995;Anderson & Wincoop, 2003). The dummy variable for Border is unity if countries i and j share a common border and 0 when they do not.…”
