In the ‘currency wars’ discussion, it is almost taken for granted that exchange rate depreciations will result in non-trivial export gains.  Using evidence from countries in Europe and Asia, this column argues instead that factors unrelated to prices/exchange rates often play a predominant role in shaping trade developments. Moreover, these factors affect export outcomes in a very diversified manner across countries, in part because of the interplay of global value chains.

With the rise of global value chains, trade in intermediates now accounts for more than two-thirds of total trade. This column provides evidence that trade in parts and components of capital goods between new and old EU countries is driven by wage differences across countries. It further shows that wage differences play an important role in the ex ante investment decision to establish a new production network.

Now that the worst of the Eurozone Crisis has passed, one question that emerges is whether improving current account balances should be an objective for policymakers. And if so, what tools are available? This column argues that because of the emergence of global value chains, trade imbalances within the Eurozone are to a large extent an endogenous result of the international organisation of production at the firm level. It is therefore better to disregard intra-EZ imbalances and focus on the total.

Global value chains have increased the complexity of good economic analysis no end. This column assess the extent to which global value chains change how we think about the world, and argues that the evolution of global market shares is no longer an adequate indicator of a country’s competitiveness in most cases. ‘Made in China’ has changed almost everything.

While domestic content in exports has been declining globally, the opposite trend has been observed in China. This column argues that this is mainly due to the structural transformation and FDI liberalisation in the country since 2000. As a result, individual processing exporters have substituted domestic for imported materials, both in terms of volume and varieties. These results indicate that China has become more competitive, particularly in the intermediate input sectors, which supports its ascent along the global value chains.

Building on Antras and Chor (2013), we describe a property-rights model of firm boundary choices along the value chain. To assess the evidence, we construct firm-level measures of the upstreamness of integrated and non-integrated inputs by combining information on the production activities of firms operating in more than 100 countries with Input-Output tables. In line with the model’s predictions, we find that whether a firm integrates upstream or downstream suppliers depends crucially on the elasticity of demand for its final product. Our results suggest that contractual frictions play an important role in shaping the integration choices of firms around the world.

The export-less depreciation of the yen has opened a debate on the power of exchange rates to boost exports. This column presents new evidence on how the exchange rate elasticity of exports has changed over time and across countries, and how global value chains have affected it. The upshot is that greater integration in global value chains makes exports substantially less responsive to exchange rate depreciations.

Manufacturing is often seen as the key to sustainable export and productivity growth in developing countries. This column argues that, while manufacturing played a key role in some countries’ development, high growth can be sustained without relying primarily on manufacturing. A process of learning, productivity improvement, and investment that touches all sectors characterises the most successful economies. Policies that artificially favour manufacturing should instead give way to maximising learning from the frontier in all sectors of the economy.

Global value chains (GVCs) clearly promote trade and investment but their impact on domestic value-added is less clear. This column discusses new evidence showing that GVCs participation stimulates domestic value, but not for all nations. It is necessary for low- and middle-income countries to increase their absorptive capacities if they are to reap benefits from GVC participation.

While Brazil has become one of the largest economies in the world, it remains among the most closed economies as measured by the share of exports and imports in GDP. This column argues that this cannot be explained simply by the size of Brazil’s economy. Rather it is due to a reliance on domestic value chain integration as opposed to participation in global production networks. Greater trade openness could produce efficiency gains and help Brazil address its productivity and competitiveness challenges.

The past three years have witnessed a slowdown in global trade. This column shows that the slowdown was particularly pronounced in advanced economies, especially the Eurozone. In a panel of 18 OECD economies, most of the slowdown can be explained by cyclical factors. However, structural factors – global value chains and especially protectionism – may have played a role too.

While participation in global value chains is giving developing countries the opportunity to diversify production and to acquire know-how from global buyers, few countries in Latin America are taking advantage of these new forms of production. Using a combination of innovative datasets at the macro and micro levels this column presents a comprehensive picture of the participation of Latin America and the Caribbean in global value chains and describes why it is so low.

The rise of trade in intermediate inputs is well documented, but its role in shaping domestic economies is not yet completely understood. This column presents evidence from French firms on the effects of importing intermediate inputs. Firms importing more varieties of intermediate inputs increased their productivity and exported more varieties. Foreign inputs from the most advanced economies have the strongest effect on firm productivity, but imported inputs from all countries help raise the number of export varieties.

Brazil has grown rapidly and reduced poverty over the past decade, but it has grown more slowly than other emerging economies and its income per capita remains relatively low by global standards. This column points out that sectors of the Brazilian economy that have been opened up to international competition have outperformed those that remain heavily protected. Deeper integration into global markets and value chains could provide competitive pressures that would improve Brazil’s productivity and living standards.

The explosion of trade in intermediate goods has created new development opportunities, but many of the jobs at the bottom of global value chains are low-paid, insecure, and dangerous. This column argues that participation in global value chains brings risks as well as opportunities. The gains from ‘moving up the global value chain’ are not equally distributed – large, professional, high-tech firms with diversified export markets, and high-skilled workers with formalised contracts benefit the most.

Joining international production networks has been the successful path to industrialisation taken by some Asian and eastern European countries in the last decades. This column argues economic integration agreements are a major force behind the formation of these international linkages. Using a global dataset of establishments to measure global value chains, it shows that countries with integration agreements have 8% more linked subsidiaries.

Global value chains play an important role in many nations’ globalisation and development policies. Using a new indicator based on a global dataset – the World Input-Output Database – this column shows that international production networks have, since 2000, spread across regional blocs faster than they have spread within them. ‘Factory World’ is still a work in progress, but the construction is progressing rapidly

One common measure of trade linked international production networks is the so-called VAX ratio, i.e. the ratio of value-added exports to gross exports. This column argues that this measure is not well-behaved at the sector, bilateral, or bilateral sector level, and does not capture important features of international production sharing. A new gross trade accounting framework is proposed that can better track countries’ movements up and down global value chains.

Zhi Wang, Shang-Jin Wei, Kunfu Zhu, 07 April 2014

The growth of international trade in intermediate inputs means that standard trade statistics can give a misleading picture of the real patterns of production behind world trade. This column introduces an accounting framework that decomposes traditional trade flows into components that better reflect the underlying location of the value addition linked to exports.

Michael Ferrantino, Daria Taglioni, 06 April 2014

Recent growth in trade has decelerated significantly since its sharp recovery in 2010. This column discusses the role of global value chains in international trade and their contribution to the trade slowdown. Trade in complex products organised by global value chains, in particular motor vehicles, has been more sensitive to global downturn than has trade in simple products. Thus, either focusing on simpler products less dependent on global value chains, or diversifying the export folios, could be useful in reducing the risk of a slowdown in global merchandise.
