Gravity has long been one of the most successful empirical models in economics. Incorporating deeper theoretical … foundations of gravity into recent practice has led to a richer and more accurate estimation and interpretation of the spatial … relations described by gravity. Wider acceptance has followed. Recent developments are reviewed here, and suggestions are made …

We dedicate much … to the explanation of the micro-foundations of the gravity equation and to the solution of the Border Puzzle achieved in … Gravity and NEG relations, are discussed in order to show how much these two theories are used in empirical trade analysis. …

Distance effects in empirical gravity equations appear to be too high to be explained by transport costs alone … existing empirical evidence. An empirical gravity equation is used to estimate the effect of exporter networks on distance …
