This article has explored whether Aid for Trade (AfT) flows that accrue to recipient-countries depend on the latter's level of export product concentration. The analysis covers a sample of 133 countries over the period 2002-2017. The findings indicate that least developed countries (LDCs) receive higher AfT flows when they experience a rise in the level of export product concentration, while NonLDCs enjoy higher AfT flows when they diversify export products. Interestingly, higher amounts of AfT accrue to countries that diversify their export product basket towards manufacturing products, although different result patterns appear for the components of manufactured exports.
