Economic research and trade policy analysis

This paper tries to assess quantitatively the role of electronic commerce in economic activity and in trade and tariff revenue collection. The share of value added that potentially lends itself to electronic trade represents around 30 percent of GDP, most importantly distribution, finance and business services. Electronic commerce is also likely to boost trade in many services sectors significantly. Despite the growing importance of electronic commerce for economic activity and trade, tariff revenue loss from electronic commerce is likely to be minimal. Trade in potentially digitizable media goods which currently faces a tariff in some countries represents less than one percent of total world trade. The revenue collected on these products amounts to less than one percent of total tariff revenue in most countries. Even if some of this trade moved “online”, tariff revenue loss would be only a very small share of tariff revenue.

This paper analyzes the reasons why countries may pursue different labeling policies in autarky and how this affects countries’ welfare in the context of international trade. In an asymmetric information environment where producers know the quality of the goods they are selling and consumers are not able to distinguish between them, the quality governments choose to protect by a label depends on consumer preferences for and production costs of different qualities. Countries with different distributions of tastes and/or different production functions will thus decide to label differently. When they trade, welfare effects will be different on the country as a whole and on different types of consumers within each country depending on whether countries choose to mutually recognize each others labeling policy or to harmonize their policies. In particular it will be the case that a country with weak preferences for high quality will oppose the introduction of an international, harmonized label as it is better off under a regime of mutual recognition. When countries only differ in their costs of producing quality instead, none of the trading partners will lose from a move towards trade under an international, harmonized label.

What is the value of the WTO Committee on Agriculture? How much trade do countries talk about at the WTO? Do low-income countries participate less than they should in the work of the Committee? How important are issues not covered by notifications? What are the most important issues on which to focus negotiations?

to identify underlying sources of growth or decline. A key feature is that the unit of analysis (e.g. a city, a region or a country) exists within a broader frame of reference that strongly influences it (e.g. a national productive system or the world economy). It is based on the principle that total change can be disaggregated into contributing factors and any change that can not be accounted for by these factors can be interpreted as the "local contribution" to that total change. This method has been subject to many refinements. Because the objectives of this paper are both didactic and analytic, traditional Shift-Share Analysis is applied to international trade. It uses the "constant market share" assumption by decomposing the growth of exports into four separate components: a global component (GLOBO) indicating changes due to overall growth of world trade, a geographical component (GEO) indicating changes due to the country's distribution of trading partners, a product composition component (COMPO) indicating growth due to the mix of products exported, and a residual term (the "local" contribution) indicating changes in competitiveness, or performance (PERFO). The first 3 components, GLOBO, COMPO and GEO all relate to the "expected change in trade" should trade change proportionally. The fourth and residual component, PERFO, refers to that part of the change in trade that "shifts away" from expected proportional changes, hence the term "Shift-Share Analysis". This paper will analyse a change or "shift" in shares in trade (particularly exports) of different economies. By focusing on selected time periods and using the PERFO indicator, the method will show what industries shift away from the expected change in trade, which economies have experienced such shifts in their industries, and to which regions.

Services is the fastest-growing sector of today's global economy and trade in services is the most dynamic segment of world trade. However, its potential remains constrained by a variety of barriers: trade costs are estimated to be almost double those in goods, and more than 40% of trade costs are accounted for by regulation-related factors. Regulatory measures related to the permission to supply a service, i.e. those related to licensing and qualifications requirements and procedures, and technical standards, can particularly affect service suppliers' ability to trade. With a view to mitigating the unintended trade-restrictive effects of such measures, since 2017, a group of Members has been negotiating a set of regulatory disciplines in the context of the Joint Initiative on Services Domestic Regulation.

We examine in this paper the impact of the tightening of IPRs, notably patents rights, and the adoption of utility model laws on export diversification. To perform our analysis, we used panel data covering 89 developing and developed countries (of which 55 developing countries) over the period 1975 – 2003, and Lewbel (-2012-)'s instrumental variable technique. Our results lead us to conclude that for developing countries, legal protection for minor and adaptive inventions could be a springboard for further strengthening of IPRs protection in spurring export diversification, which is essential for the structural change needed for their economic development.

In September 2015, Heads of State and Government will gather in New York to agree the post-2015 development agenda. The role that trade will play in this agenda is neither clear, nor agreed. Yet an open, non-discriminatory, rules-based multilateral trading system underpins sustainable development - a concept that lies at the core of much of the post-2015 debate to date. Indeed, sustainable development is recognized as an objective in the Marrakesh Agreement Establishing the World Trade Organization (WTO). With the aim of stimulating discussion, this paper asks the question of how trade, and WTO rules, can contribute to the post-2015 development agenda? In reply, the author offers some thoughts on 10 contributions that trade, and WTO rules, can make to the post 2015 development agenda. The list is indicative, not exhaustive. The 10 contributions highlight the complex way in which trade and trade policy interact with the evolving debate on the post-2015 development agenda - a debate which encompasses issues ranging from poverty eradication, inclusive growth, climate change mitigation, decent work, food security, access to health services and sustainable development financing, to name but a few of the topics under consideration. The paper organizes the 10 indicative contributions around three headings: trade rules as part of the enabling environment for the achievement of the post-2015 development agenda; the role that trade, and trade policy, can play in meeting specific goals (including possible Sustainable Development Goals); and the contribution that Aid for Trade can make.

Over the past months, it has become increasingly clear that the services negotiations under the Doha Development Agenda will not produce significant improvements on current commitments unless major new impetus is provided. In an introductory section, this paper discusses various impediments, from the perspective of participating governments, that may explain the lack of negotiating momentum to date. It then provides an overview of existing commitments under the GATS (by sector, mode of supply, and level of development) and of the initial offers that had been tabled by early 2005. Despite the substantial benefits that may be associated with the liberalization of services trade, the GATS has obviously not yet lived up to ambitious expectations. For example, on average across all WTO Members, only one-third of all services sectors have been included in current schedules of commitments; and many entries have been combined with significant limitations on market access and national treatment or with the complete exclusion of particular types of transactions (modes of supply) from coverage. While the ongoing services negotiations provide an opportunity to complement the rule-making efforts of the Uruguay Round with genuine market opening, many governments apparently have found it difficult, despite generally more restrictive access regimes and, thus, potentially higher gains from liberalization than in merchandise trade, to undertake or envisage economically significant bindings across a broad range of services. Five years after the inception of the services round, current negotiating arrangements, based mainly on (bilateral) exchanges of requests and offers, may need to be complemented by common points of reference to provide greater focus and guidance.

The Marrakesh Agreement establishing the WTO recognizes the need for positive efforts designed to ensure that developing countries and especially the least developed among them secure a share in the growth in international trade commensurate with the needs of their economic development.This article discusses how the WTO contributes to facilitating Africa’s integration into the WTO multilateral trading system. It is argued that, while African countries are actively engaged in the work of the WTO, securing their economic and policy interests, some main challenges remain. These include the need to further diversify production, linking to the Global Value Chains and developing adequate infra-structures facilitating digital trade as a vehicle for economic growth.

In this paper I sketch out the rough contours of the challenge faced by the WTO in dealing with non-tariff measures (NTMs) as seen from the economic theories of trade agreements. The key questions for the WTO - the answers to which largely dictate the choice between shallow and deep approaches to integration – appear to be two: (1) Is it the terms-of-trade problem or the commitment problem that WTO member governments seek to solve with their WTO membership?; and (2) Is it market clearing or offshoring/bilateral bargaining that is now the most prominent mechanism for the determination of international prices? I suggest that evidence on the first question points to the terms-of-trade theory and hence toward shallow integration, but that answering the second question may be the key to identifying the best way forward on NTMs for the WTO.

This paper develops a set of time series models to provide short-term forecasts (6 to 18 months ahead) of international trade both at the global level and for selected regions. Our results compare favourably to other forecasts, notably by the International Monetary Fund, as measured by standard evaluation measures, such as the root mean square forecast error. In comparison to other models, our approach offers several methodological advantages, inter alia, a focus on import growth as the core variable, the avoidance of certain difficulties affecting the performance of structural models, the selection of variables and lags on the basis of theoretical considerations and empirical testing as well as a full documentation of the modelling process.

The objective of this manuscript is to serve as a practical guide for estimations with the structural gravity model. After a brief review of the theoretical foundations, we summarize the main challenges with gravity estimations and we review the solutions to address those challenges. Then, we integrate the latest developments in the empirical gravity literature and we offer six recommendations to obtain reliable partial equilibrium estimates of the effects of bilateral and non-discriminatory trade policies within the same comprehensive, and theoretically-consistent econometric specification. Our recommendations apply equally to analyses with aggregate and disaggregated data. Interpretation, consistent aggregation methods, and data challenges and sources for gravity estimations are discussed as well. Empirical exercises demonstrate the usefulness, validity, and applicability of our methods.

This study surveys safeguard provisions on trade in goods in 232 regional trade agreements (RTAs) notified to the GATT/WTO up to 31 December 2012. In particular, it identifies those RTAs that modify the conditions applicable to the RTA partner (either substantively or procedurally) in the event that a global safeguard is invoked. In the case of bilateral (or intra-RTA safeguards), the study analyses provisions governing injury assessment, causation, conditions for the invocation of a measure and the types of measures that may be employed. We use the yardstick of GATT Article XIX and the WTO Safeguards Agreement to determine whether the provisions applicable to bilateral safeguard measures are more or less stringent than the corresponding multilateral rules. The study also includes an inventory of infant industry, balance of payments, and special safeguards applicable to agricultural products found in RTAs. We demonstrate through various examples that safeguard provisions have become more prescriptive in recent years, though little homogeneity in their design is found even for a given country. In the case of global safeguards, roughly a quarter of RTAs provide for the possible exclusion of the RTA partner, subject to certain criteria, thus discriminating against non-parties. In the case of bilateral safeguards, some RTAs use looser language to define the trigger mechanism to invoke a safeguard and to determine injury standards, thus potentially offering greater scope to use such measures. We found wide variety in the types of bilateral safeguard measures that are permitted in RTAs. A number of more recent RTAs tighten the conditions for application of a bilateral safeguard through limiting the duration of the safeguard measure, allowing the use of tariff-based measures only, and binding the use of the measure to the transition period. Other RTAs specify neither the length of the bilateral safeguard measure nor the conditions for its reapplication, thus providing greater scope to impose such measures than in the multilateral context.

There are essentially two types of plurilateral trade agreements (PAs) among WTO Members, n exclusive and an open variant. While the benefits of the former agreements are shared among participants only, the latter are implemented on an MFN-basis, thus profiting non-signatories as well. The most prominent examples are the Information Technology Agreement (1996) and the Fourth and Fifth Protocols under the GATS (1997) on telecom and financial services, respectively. To preclude ‘free riding’, their entry into force was made contingent on the participation of a ‘critical mass’ of countries. The respective benchmarks, usually market shares of some 80% or more, are quite challenging, however. To promote more widespread use of plurilaterals, given the plethora of pressing policy concerns, whether investment-, competition- or labour-related, and the persistent stalemate in the Doha Round negotiations, the conclusion of exclusive agreements is thus being (re-)considered in ongoing policy discussions. This article takes a sceptical view, since any such PA would need to be agreed by consensus among all 160-odd WTO Members. It may prove more rewarding to further explore the potential of open agreements to address policy concerns among interested Members either in the form of co-ordinated improvements of their current schedules or, if not covered by existing treaty frameworks, as ‘WTO-extra’ understandings.

This paper investigates the scope for international rules to address market failures in trade in natural resources and the associated international transactions of prospecting and investment in resource exploitation. We argue that several market failures are likely to have substantial costs. However, due to the distinctive features of natural resources, the market failures are particular to them. The ad hoc approaches which have attempted to address them to date leave scope for a more systematic and comprehensive approach by the WTO, but the distinctive features of natural resources imply that this could not simply be an application of the rules appropriate for other forms of trade.

The Trade Policy Reviews conducted in the Western Hemisphere over 1989-2009 contain a wealth of information that puts in clear evidence the considerable improvements achieved in most American countries during the first two decades of operation of the Trade Policy Review Mechanism. Those Reviews show that trade liberalization came hand-in-hand with internal reforms, and was generally of an autonomous nature and an intrinsic component of improved economic management. Trade liberalization slowed down during the second decade under review, with tariffs having come down mostly during the earlier years. The use of non-tariff barriers also fell over time although at a slow pace in some of the smallest Members, which found it difficult to implement the more complex trade policy instrument applied by larger countries. Export and other government assistance schemes proliferated throughout the continent but were often characterized by a lack of unity in the criteria used to assign and apply them. The review period also witnessed enormous changes in the services sectors, where reforms usually proved more complex than in the goods area. The multilateral and other international trade agreements contributed to the stability of trade policies and the general rejection of protectionism, although backtracking did occur in a number of cases. Because the commitments made during the Uruguay Round negotiation now fall short of the more liberal trade regimes that came to be over the review period, most Members in the Americas could presently raise trade and investment barriers without violating multilateral rules. Thus, the pressing need to conclude the Doha Development Agenda in order to lock in the considerable trade policy liberalization achieved during past years, and to strengthen the multilateral trading system.

Transitioning from the post-2008 financial meltdown to a sustained period of global growth and prosperity involves a major challenge: how to ensure the effective management of international economic interdependence. Trade, growth, good governance and sustainable development constitute essential ingredients to any solution, as is a fairer distribution of the gains of trade. Two issues stand out in this conversation. The first concerns the unfinished business of the global fight against the scourge of poverty, which impacts one region more than most: Africa. At the same time, a key pre-requisite for economic performance - affordable and efficient public infrastructure and services – remains lacking in this region – notably, in Sub-Saharan Africa. To address this, the region itself has initiated a major, long-term, continent-wide infrastructure development programme which is intended to fix this problem sustainably - namely, the Programme for Infrastructure Development in Africa (PIDA). Its success foreshadows an economic transformation that will potentially usher in an emergent Africa in the 21st century. Secondly, in one area of economic activity – trade in government procurement markets - the revised WTO Agreement on Government Procurement (GPA) is emerging as a multi-dimensional tool of trade, governance and development. The thesis of this paper is that GPA participation by African countries - a prospect which, to date, they have declined to take up - holds strong potential to reinforce the positive effects of PIDA and to contribute to the region's growth and development more generally. Developing this thesis, the paper examines the possible application of the GPA to support Africa's infrastructure programme, drawing on its three dimensions of instrument of governance, market access instrument, and 'policy space' instrument in support of the development, financial and trade needs of developing countries. Based on the analysis, the paper concludes that the potential benefits outweigh the potential costs of participation in the GPA by African countries, and, accordingly, that the GPA merits consideration by the region in this regard. A successful implementation of the infrastructure programme also portends a significant expansion in the size of the African government procurement market. Were African countries to accede to the Agreement in this context, it would constitute not only a big rise in membership numbers, but also a significant expansion in the value of market access under the Agreement. The broad outlines of a potential win-win scenario for both African countries and GPA Parties thus begin to emerge. The paper, nonetheless, acknowledges that delivering these benefits would involve significant practical and political challenges. It concludes that if the challenges can be overcome and the mutual benefits delivered, the revised GPA would have been demonstrated as an effective tool for balancing flexibility and reciprocity in the government procurement sector, consistent with sustainable development principles, with the capability to deliver win-win benefits for a broad range of stakeholders, in the post-2015 era.

We examine the effects of transit, documentation, and ports and customs delays on Africa’s exports. We find that transit delays have the most economically and statically significant effect on exports. A one day reduction in inland travel times leads to a 7 percent increase in exports. Put another way, a one day reduction in inland travel times translates into 1.5 percentage point decrease in all importing-country tariffs. In contrast, longer delays in the other areas have a far smaller impact on trade. We control for the possibility that greater trade leads to shorter delays in three ways. First, we examine the effect of trade times on exports of new products. Second, we evaluate the effect of delays in a transit country on the exports of landlocked countries. Third, we examine whether delays affect time-sensitive goods relatively more. We show that large transit delays are relatively more harmful because of high within-country variation.

Albeit nominal tariffs have been decreasing in the past decades, the rise of global manufacturing along global value chains lead to their accumulation along the international supply chain. The calculation of effective protection rates provides important insights on the impact of nominal protection on the international competitiveness of industries in a trade in tasks perspective. Building on the results of the OECD-WTO Trade in Value-Added TiVAdatabase, the paper analyses the evolution of effective protection in about 50 developed and developing countries from 1995 to 2008. The paper reviews also the role of preferential agreements on effective protection as well as the impact of tariffs on the production costs of services. A final chapter is dedicated to exploring the underlying patterns that may exist beyond the EPR profiles.

The revolution in the telecommunication industry of recent years raises a number of interesting economic questions with significant policy implications. One of these questions is the extent to which foreign investments in the telecommunication industry is accompanied by policies that are conducive to cross–border investments. These policies can be both domestic and international. The discussion in this paper is limited to the latter by concentrating on the role of the WTO and other international agreements. The purpose of the paper is to evaluate the GATS/Telecom Agreement. This is done by looking at the guiding principles for negotiating market access for foreign investors, by comparing the Agreement with the Telecom Agreement under NAFTA and by discussing the merits of the multilateral approach to negotiating foreign investment in the telecommunication sector. The WTO GATS/Telecom Agreement comes out rather well from this evaluation exercise.

MERCOSUR is one of the most important examples of renewed world-wide interest in regional trade agreements. It may be seen as a consolidation of unilateral reforms undertaken in conjunction with major macroeconomic adjustments. The paper reviews the objectives of MERCOSUR and assesses its achievements, focusing on institutions and fulfilment of commitments. It concludes that considerable progress has been made to achieving a customs union and even beyond that towards a common (but not EU-style single) market, but there are a number of areas where progress is still to be made.

The paper investigates the role of global supply chains in explaining the trade collapse of 2008-2009 and the long-term variations observed in trade elasticity. Building on the empirical results obtained from a subset of input-output matrices and the exploratory analysis of a large and diversified sample of countries, a formal model is specified to measure the respective short-term and long-term dynamics of trade elasticity. The model is then used to formally probe the role of vertical integration in explaining changes in trade elasticity. Aggregated results on long-term trade elasticity tend to support the hypothesis that world economy has undertaken in the late 1980s a “traverse” between two underlying economic models. During this transition, the expansion of international supply chains determined an apparent increase in trade elasticity. Two supply chains related effects (the composition and the bullwhip effects) explain also the overshooting of trade elasticity that occurred during the 2008-2009 trade collapse. But vertical specialization is unable to explain the heterogeneity observed on a country and sectoral level, indicating that other contributive factors may also have been at work to explain the diversity of the observed results.

Forest plays a significant role in the overall balance of carbon in the atmosphere. Forest carbon sequestration can potentially reduce the accumulation of greenhouse gases in the atmosphere. However, when deforestation takes place, carbon is released to the atmosphere again. Globally, it has been estimated that about 11% to 39% of all carbon emissions from human origin come from the forest sector (Hao et al. 1990). Regarding global warming, the balance between forest conservation and deforestation can change forest sector activities from a solution to a problem and vice versa.

The COVID-19 pandemic has brought considerable attention to trade in medical products, and specifically trade in products for prevention, testing and treatment. This study provides a comprehensive overview of trade and tariffs imposed on medical goods in general, many of which appear to be in severe shortage as a result of the current crisis. The purpose of this note is to provide factual information on how these goods are traded globally.

This paper reviews a number of initiatives taken by public and private institutions aimed at minimizing the impact of the on-going crisis of the financial sector on its ability to supply trade finance to support trade at affordable rates. In doing so, it draws a few policy lessons. One of them is that a relatively stable segment of the financial industry is now regularly hit by the contagion of financial crises, with potentially very harmful spill-overs on global trade through a dry up of its financing. Specific policy measures to restore confidence in this otherwise safe market required a good level of coherence and dialogue between national governments and international and regional development organizations. Lessons from the Asian and Latin American financial crises of the late 1990's have been learned and academia provided input by developing understanding on a previously under-rated topic in the literature. Learning-by-doing and leadership have also been features of the policy response, which altogether had some successes. Still, longer-term challenges remain, such as addressing the structural gaps in the availability of trade finance in low-income countries - ad hoc programs have been designed to fill the gap between the perceived and actual risk of extending trade credit to traders in these countries. Moreover, regulation of the trade finance market needs to continue to take into account its low-risk character, the absence of leverage and its impact on development.
