This result can be explained by the fact that the top EPP exporters are low-income Asian and African countries that have not attracted significant levels of FDI. This correlation is robust and positive for eight of the ten categories of EGs. In most cases the elasticities are also very high - significantly more than one - indicating the crucial role of technical assistance projects in explaining trade in EGs. The profile of these projects indicates that tied aid may be an important factor contributing to trade in EGs to developing countries.
