Abstract

This paper is aimed at multiplicatively estimating the parameters of the gravity equation by using the Poisson Pseudo-Maximum-Likelihood (PPML) estimator, and taking heteroskedasticity into account at the same time. Besides, in order to compare the results, the model will be estimated trough OLS and Tobit, and the precision of the different estimators will be assessed by a set of specification tests. Results indicate that the effects of Preferential Trade Agreements are very sensitive to the method chosen to estimate the gravity model and the results obtained under PPML are the most reliable.
