Introduction

Over the past decades, trade flows have become increasingly global. Today, South- South trade represents around one-half of global trade and the top ranks of major traders are not exclusively occupied by industrialized countries (OECD, 2010). Trade now spans all major world regions and continues to grow within and across those regions. Trade also takes new forms as trade in goods is increasingly accompanied by trade in tasks. Capital flows more freely across regions and trade and capital flows together have contributed to an increased transfer of technological change across regions. There is a strong sense that companies and countries well integrated in these global networks are part of a virtuous circle involving technological progress and growth. Not being connected, however, can represent a very serious bottleneck for future growth and economic development.
