Book excerpt: Research Paper (postgraduate) from the year 2010 in the subject Business economics - Trade and Distribution, course: Technical-paper/ Private research, language: English, abstract: This paper explores the extent to which products and product-markets diversifications contribute to export growth. It has used the bilateral trade at a very detailed level across countries, between 1996 and 2008. The results suggest that the export growth comes mainly from the intensive margin, i.e. product lines that had been already exported to the existing established trading partners. The decline in export, either due to the fall or the extinction in the existing established trade relationships, occurs more substantially on export growth for developed countries than for developing countries. And the appearance of new exports (extensive margin), either new products or markets, represents a vital source in export earnings for the developing countries, especially for the least developed countries (LDCs).
