This paper focuses on the sluggish growth of world trade relative to income growth in recent years. The analysis uses an empirical strategy based on an error correction model to assess whether the global trade slowdown is structural or cyclical. An estimate of the relationship between trade and income in the past four decades reveals that the long-term trade elasticity rose sharply in the 1990s, but declined significantly in the 2000s even before the global financial crisis. These results suggest that trade is growing slowly not only because of slow growth of Gross Domestic Product (GDP), but also because of a structural change in the trade-GDP relationship in recent years. The available evidence suggests that the explanation may lie in the slowing pace of international vertical specialization rather than increasing protection or the changing composition of trade and GDP.

The global economy is at a critical juncture today. According to the International Monetary Fund's latest World Economic Outlook, global gross domestic product (GDP) is set to grow at only 3.1 percent this year, the lowest rate of growth since the Global Financial Crisis. Investment and productivity remain subdued, despite extremely low and even negative interest rates in many economies. One key aspect of global weakness that is of particular relevance to emerging Asian economies is the sharp slowdown in global trade. This slowdown represents a notable departure from the "normal" times of the past few decades, and is the subject of my remarks today.

Global trade growth has slowed since 2012 relative both to its strong historical performance and to overall economic growth. This paper aims to quantify the role of weak economic growth and changes in its decomposition in accounting for the slowdown in trade using a reduced form and a structural approach. Both analytical investigations suggest that the overall weakness in economic activity, particularly investment, has been the primary restraint on trade growth, accounting for over 80 percent of the decline in the growth of the volume of goods trade between 2012–16 and 2003–07. However, other factors are also weighing on trade in recent years, especially in emerging market and developing economies, as evidenced by the non-negligible role attributed to trade costs by the structural approach.

The global financial crisis of 2008/9 is the Great Depression of the 21st century. For many though, the similarities stop at the Wall Street Crash as the current generation of policymakers have acted quickly to avoid the mistakes of the past. Yet the global crisis has made room for mistakes all of its own. While governments have apparently kept to their word on refraining from protectionist measures in the style of 1930s tariffs, there has been a disturbing rise in "murky protectionism." Seemingly benign, these crisis-linked policies are twisted to favour domestic firms, workers and investors. This book, first published as an eBook on VoxEU.org in March 2009, brings together leading trade policy practitioners and experts - including Australian Trade Minister Simon Crean and former Mexican President Ernesto Zedillo. Initially its aim was to advise policymakers heading in to the G20 meeting in London, but since the threat of murky protectionism persists, so too do their warnings.

Asia and China made disproportionate contributions to the slowdown of global trade growth in 2015. China’s import growth slowed starkly, driven by both external and domestic factors, including a rebalancing of demand. Econometric results point to weak investment and rebalancing as the main causes of the import slowdown. Spillover effects from China’s rebalancing are estimated for some 60 countries using value-added trade data, and are found to be more negative on Asia and commodity exporters than others.
