Comparing alternative methods to estimate gravity models of bilateral trade Gómez-Herrera, Estrella International trade Gravity model Estimation methods 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. 2014-05-05T12:48:59Z 2014-05-05T12:48:59Z 2010 report Gómez-Herrera, E.
