We estimate annual gravity equations for 1960-85 on a large sample, allowing us to identify time trends in the coefficients. Our results include the following: (1) The weight of exporter's supply has increased relative to importers' demand in explaining the long-run strong performancee of global...

In recent decades, the growth of information and communications technologies (ICT) and the move toward the digitalization of trade and global value chains has been radically transforming the global trade scene, with important implications for women engaged in trade. In order to identify adequate...

Many improvements have been proposed for the basic gravity model specification, most of which are confirmed by standard statistical tests due to the large number of observations often used to estimate such models. We use Monte Carlo experiments to examine situations in which features of models...

Significant progress has been made in quantifying the effects of non-tariff measures since OECD commissioned its last major review of this topic in 1997. This paper reviews the literature of NTMs and assesses the different methods available. Additionally, the paper develops a series of questions...
