Structural new trade theory models have never been used to evaluate and quantify the role of preferential trade agreement (PTA) membership for trade in a way which is consistent with general equilibrium. Apart from filling this gap, the present paper aims at delivering an empirical model which takes into account both that PTA membership is endogenous and that the world matrix of bilateral trade flows
contains numerous zero entries. These features are treated in an encompassing way by means of (possibly two-part) Poisson pseudomaximum likelihood estimation with endogenous binary indicator variables in the empirical model. (JEL F11, F13, F15)
