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.

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.

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.

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.

The depreciation of the yen by 19% since December 2012 has been a concern for many of Japan’s trading partners. Is it really bad news? This column explains that the answer depends on the structure of global value chains. It describes two approaches to incorporate the international fragmentation of production in measures of price competitiveness that can provide new insights.

As the Doha Round continues to stagnate, mega FTAs such as the Trans-Pacific Partnership will likely play the leading role in trade rulemaking for some time to come, creating a 'spaghetti bowl' of trade rules. This column argues that we should multilateralise the results of mega FTAs on an issue-by-issue basis, starting with an International Supply Chain Agreement.

The rise of global value chains (GVCs) is posing new challenges to analyses of countries’ competitiveness. Commonly used measures such as gross exports and revealed comparative advantage are becoming obsolete. This column presents a new measure called ‘global-value-chain income’ that is based on the value added by countries along the international production chain. It shows how this measure can be derived from existing industry-level data and how it changes our view on a country’s competitive strengths.

The rise of international production sharing – ‘global value chains’ – has transformed international commerce and pushed economists into new territory. This column argues that there is evidence to suggest that old-fashioned protection can have an unexpected negative effect on firms that are part of a global value chain. In an increasingly globalised world, exporters’ success seems to positively depend on the free entry of imports rather than the other way round.

CEPR Policy Insight No 64 argues that adapting world trade governance to the realities of supply-chain trade will require a new organisation – a WTO 2.0 as it were.
