Resumen
The gravity equation has been traditionally used to predict trade flows across countries. However, several problems related with its empirical application still remain unsolved. In this paper, I provide a survey of the recent literature concerning the specification and estimation methods of this equation. In addition, I compare the performance of two widely extended estimators, panel OLS and Poisson Pseudo Maximum Likelihood (PPML), for a dataset covering 80% of world trade.
