Gross trade accounting: A transparent method to discover global value chain-related information behind official trade data: Part 1
Zhi Wang, Shang-Jin Wei, Kunfu Zhu07 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.

Production segmentation across national borders has become an important feature of the world economy. With the rapid increase in intermediate trade flows, trade economists and policymakers have reached a near consensus that official trade statistics based on gross terms are deficient, often hiding the extent of global value chains. There is also widespread recognition among the official international statistics agencies that fragmentation of global production requires a new approach to measure trade, in particular the need to measure trade in value-added.
Excessive short-termism is always a problem for policy, but the Global Crisis has brought it sharply into focus. This column introduces a report that discusses how a shift to longer-term solutions is necessary and possible. A key message is that businesses as well as governments need to take a longer-term view. The report identifies ways to overcome the current impasse in key economic, climate, trade, security, and other negotiations.
Just when we thought high-frequency trading couldn’t get any faster, a US communications company is developing a high-speed laser network between the New Jersey data centres of the New York Stock Exchange and the NASDAQ stock exchange, to shave an additional few nanoseconds off high-frequency trading times.
Waste of effort? International environmental agreements
Derek Kellenberg, Arik Levinson01 March 2014
Economic theory predicts that international environmental agreements will fail due to free-rider problems, and previous empirical work suggests that such agreements do not in fact reduce emissions. This column presents evidence that the Basel Convention and Ban on trade in hazardous waste has also been ineffective. The authors find no evidence that Annex-7 countries that ratified the Ban slowed their exports to non-Annex-7 countries as the agreement requires.

To address environmental problems that span national borders, countries have negotiated more than 1,000 international environmental agreements (IEAs). But do they work? According to most theoretical economic models, because of free-rider problems IEAs cannot reduce pollution much below business-as-usual levels (Barrett 1994, 1997; Carraro and Siniscalco 1993; Finus and Maus 2008). Of course, game-theoretic models rarely predict real-world behaviour, which leaves room for hope that IEAs might be effective in practice.
Before the introduction of the euro, it was hoped that by promoting increased intra-regional trade it would increase business-cycle synchronisation within the Eurozone, and thus help it to fulfil the criteria for an optimum currency area. This column presents recent research that compares the evolution of business-cycle synchronisation in the Eurozone and east Asia. While the euro has had some impact on business-cycle synchronisation in the Eurozone, it has done so not through increased intra-regional trade intensity, but rather through some other channel – most likely financial integration.
World-leading trade lawyer, Gary Horlick, talks to Viv Davies about the 2013 WTO Bali ministerial conference and the post-Bali agenda. Horlick discusses food security, agriculture and whether mega regional trade agreements pose a threat to the future of the WTO. They also discuss the potential benefits of the post-Bali agenda for developing countries and the ‘trade transforming’ effect of SMEs and the internet. The interview was recorded in January 2014.
Alejandro Jara talks to Viv Davies about the 2013 WTO Bali ministerial conference and the recent Vox report, ‘Building on Bali’, co-edited with Simon Evenett. Jara presents his views on the post-Bali agenda, mega regional trade agreements and trade protectionism. They also discuss the extent to which the ‘global value chain revolution’ has changed the nature and focus of international trade and trade agreements. Jara concludes by presenting policy recommendations for the way forward. The interview was recorded in January 2014.
The global value chain revolution has changed trade and trade agreements. Trade now matters for making goods as well as selling them. Trade governance has shifted away from the WTO towards megaregional agreements. This column argues that 21st-century regionalism is not fundamentally about discrimination, and that its benefits and costs are best thought of as network externalities and harmonisation costs respectively. More research is needed to determine how the megaregional trade agreements across the Pacific and Atlantic will fit with the WTO.
Trade and trade agreements used to be relatively simple. Trade primarily meant trade in ‘made-here-sold-there’ goods, so 20th-century regional and multilateral trade agreements dealt primarily with barriers to goods crossing borders – especially tariffs. For governments, the key purpose of trade and trade agreements was to help their firms sell things.
Rich nations tend to specialise in manufacturing high-quality products – an achievement that many emerging markets are eager to imitate. But high-quality specialisation could stem either from proximity to high-income consumers, or proximity to high-skill labour. This column discusses research that quantifies the contributions of these two mechanisms by looking at quality-specialisation across US cities. Plant-level data shows that proximity to consumers matters at least as much as differences in plants’ workforces.
The well-known Linder hypothesis (1961) posits that profitably exporting a product requires robust demand for that product in the exporter's home market. Since higher-income consumers tend to purchase higher-quality products, Linder conjectured that demand by local consumers causes high-income countries to produce and export high-quality products. In contrast, the canonical factor-abundance theory of comparative advantage argues that high-income countries’ greater supply of capital and skills is the reason why they export high-quality products.
Global value chains, interdependence, and the future of trade
Pascal Lamy18 December 2013
The emergence of intra-firm trade as the primary component of international trade reflects a global interdependence in the production process. In this column the former Director-General of the WTO argues that this necessitates a re-examination of how we think about – and how we measure – trade between nations. Interdependence allows different sectors to add value, and complicates the implementation of trade barriers. Only with a modern perspective can effective trade policy be conducted.

Today, the expansion of global value or production chains means that most products or services are assembled with inputs from many countries. We may still think in terms of Ricardo’s world of trade between nations, but in reality most trade now takes place within globe-spanning multinational companies and their suppliers. The results of this ‘trade in tasks’ are all around us.
The WTO signed a mini-package of trade initiatives in Bali last week. This column argues that the ‘Bali package’ is welcome but not enough. Without some new initiative or direction, the WTO looks set to drift for the next few years. The WTO cannot move ahead until the trans-Pacific and trans-Atlantic ‘mega-regionals’ are done or dead. In the meantime, the WTO should promote research and discussion on how 21st-century trade issues could be brought into the WTO when the time is ripe.
Bali’s success got multilateralism out of the emergency room and into the intensive care unit – but we don’t know whether the operation was a success. The Bali package is only distantly related to the heart of the 2001 agenda (WTO 2013). Indeed, the ‘Bali Package’ should really be called the ‘Bali Ribbon’ since very large parts of it were already being implemented unilaterally by members (Meltzer 2013).
