Exports of processed foods from developing countries have expanded rapidly in recent times, contributing to those countries’ development. Recent research showed that the developing country exporter’s ‘openness’ and agric resource endowment offer significant explanations of this export growth. But what if ‘openness’ is enhanced? What if processed and other food trade barriers are lowered? What if trade in manufactured goods is further liberalised? Would developing countries continue expanding processed food exports, or would resources be drawn into textiles and manufacturing? This paper discusses some approaches to multilateral negotiation of improved market access, and then applies one such approach in an attempt to shed light on the above questions.
