Economic research and trade policy analysis
The value of the Committee on Agriculture
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?
A Survey of Investment Provisions in Regional Trade Agreements
The liberalization and protection of investment flows has become an increasingly indispensable pillar of economic integration. The objective of this study is to contribute to a better understanding of the ways in which RTAs achieve such liberalization and protection. To this end, we have surveyed the investment provisions contained in 260 RTAs notified to the WTO by 31 December -2015- and in force on that date. More than half of these RTAs contain investment chapters, though they vary in terms of their substantive scope and coverage. The main categories of investment provisions in RTAs reviewed in the paper include the definitions of investment and investor, investment liberalization, investment protection and ISDS. Also included in our analysis are provisions supporting the investment framework, host state flexibilities, investment promotion, as well as provisions on sustainable and socially responsible investment.
Market Shares in the Post-Uruguay Round Era
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.
Has the Multilateral Hong Kong Ministerial Decision on Duty Free Quota Free Market Access Provided a Breakthrough in the Least-Developed Countries' Export Performance?
This paper assesses the impact of the 2005 multilateral Hong Kong Ministerial decision on duty free quota free (DFQF) market access for products originating in Least developed countries (LDCs) on the latter's export performance. The analysis is conducted over a sample of 41 LDCs, with data spanning the period 1998-2013. The empirical analysis examines both the average effect and the short term/medium term effect. Results indicate that on average, this multilateral decision has exerted a positive effect on LDCs' performance on merchandise exports, with this average positive effect being solely driven by a positive effect on LDCs' export performance on primary products; the average effect on manufacturing exports has been statistically nil. In the short and medium term, this decision has exerted a positive effect on LDCs' merchandise export performance, as well as on the components of the latter, namely both primary product exports and manufacturing exports. However, the positive effect on primary product exports appears to be far higher than that on manufacturing exports. These findings have important policy implications regarding reflections on the way LDCs could utilize their policy flexibilities in the WTO Agreements to diversify their exports away from the primary sector and toward manufacturing and/or services sector.
Services Domestic Regulation
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.
The TISA Initiative
The plurilateral negotiations on a Trade in Services Agreement (TISA) have attracted much attention in trade policy circles. Policy and economic implications are intensely debated given the number and economic importance of participants. This paper aims to provide insights into the market access issues arising in such negotiations. Should TISA negotiations result in participants exchanging the best commitments they have so far undertaken in their preferential trade agreements (PTAs) – a reasonable starting point —, TISA market access commitments would go well beyond GATS commitments and services offers tabled in the Doha Round. While this would be in itself a significant outcome (especially in terms of predictability and stability), we also highlight, however, that the real economic benefits would be reduced by the fact that a number of participants have already exchanged significant concessions amongst themselves through bilateral PTAs. Further, and more importantly, exchanging 'best PTA' commitments would not meet the participants' most important export interests. These have often remained unaddressed in many of the previous bilateral negotiations or involve countries not currently participating in TISA. Addressing better these export interests would require going beyond an exchange of 'best PTA' commitments among TISA participants — with the more difficult policy and negotiating decisions that this implies — and/or seeking to expand the group of participants. We also discuss the different forms that such a plurilateral agreement may take vis-à-vis the WTO framework.
Intellectual Property Rights Protection and Export Diversification
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.
Is Trade Liberalization a Window of Opportunity for Women?
This paper analyses how trade affects women's job opportunities and earnings through five case studies: Mauritius, Mexico, Peru, the Philippines and Sri Lanka. It is found that women's share of the labour force has increased over time and the wage gap between men and women has narrowed. It is also found that there is a positive and statistically significant relation between exports and women's share of employment while there is a statistically significant and negative correlation between women's share in employment and imports. The correlation between women's share of employment and trade stems from variation between sectors rather than within sectors over time, indicating that export-competing industries tend to employ women while import-competing industries tend to employ men. Trade liberalization is likely to create jobs for women and over time increase their relative wages.
Thoughts on How Trade, and WTO Rules, Can Contribute to the Post-2015 Development Agenda
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.
Trade Policies for a Circular Economy
From its initial focus on minimizing waste generation, the circular economy has evolved into a broad-based approach to make resource use more sustainable. A big part of the appeal of a circular economy is the opportunities it creates not only for resource savings and better human health and environmental outcomes, but also for trade and economic diversification.
Turning Hills into Mountains?
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.
Measuring GATS Mode 4 Trade Flows
The paper discusses the research work which has taken place over recent years with respect to the measurement of GATS mode 4 – presence of natural persons, in the context of the revision of the Manual on Statistics of International Trade in Services. Realistic estimates of mode 4 trade are virtually non-existent. Based on the GATS legal definition, the paper introduces the statistical conceptualization of mode 4. While showing that balance of payments labour related flows indicators, such as worker's remittances and compensation of employees, cannot be used as substitutes, the paper discusses relevant balance of payments transactions in individual services sectors for estimating the value of this trade. Given the complexity of many services contracts (one service contract may involve the use of more than one mode to supply services to consumers), it provides simplifying assumptions that help build these measures of mode 4 trade in services. The paper recognizes that the proposed simplified statistical approach to modes of supply does not strictly adhere to GATS provisions and explains that it has been designed as a first guidance to provide relevant information for GATS while ensuring feasibility and consistency with statistical frameworks. Examples are given, showing the interest of some economies to estimate the size of mode 4 trade. The paper also presents how existing migration and tourism statistics could be used to assess the physical mode 4 movement (flows) and presence (stocks) in terms of number of persons. It introduces necessary extensions (separate identification of relevant mode 4 categories of persons, breakdowns by origin/destination, occupations, length of stay etc.) of these statistical frameworks in order to conduct a proper assessment of mode 4.
Africa’s Integration in the WTO Multilateral Trading System
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.
When Bad Trade Policy Costs Human Lives
Many developing countries still levy tariffs on mosquito nets, thereby discouraging their use and contributing to the spread of diseases such as malaria and dengue. Focusing on sub-Saharan Africa, the paper shows to which extent such tariffs are in place and, based on existing elasticity figures, calculates the cost of this policy.
Non-Tariff Measures and the WTO
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.
Services Commitments in Preferential Trade Agreements
Preferential trade agreements (PTAs) on services have proliferated since 2000. This working paper briefly presents the expansion of the dataset initially developed in Marchetti and Roy (2008). The data permits to assess the extent to which market access commitments undertaken by WTO Members in PTAs go beyond GATS commitments and offers made in the context of the Doha Development Agenda. The dataset, which covers PTA commitments of 53 WTO Members (counting EU Members States as one), is available at: http://www.wto.org/english/tratop_e/serv_e/dataset_e/dataset_e.htm
Forecasting Trade
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.
R&D in the Network of International Trade
Recent empirical evidence has shown that trade liberalization promotes innovation and productivity growth in individual firms. This paper argues that different types of trade liberalization – multilateral versus regional – may lead to different R&D and productivity levels of firms. Trade agreements between countries are modelled with a network: nodes represent countries and a link between the nodes indicates the existence of a trade agreement. In this framework, the multilateral trade agreement is represented by the complete network while the overlap of regional trade agreements is represented by the hub-and-spoke trade system. Trade liberalization, which increases the network of trade agreements, reinforces the incentives for firms to invest in R&D through the creation of new markets (scale effect) but it may also dampen these incentives through the emergence of new competitors (competition effect). The joint action of these two effects within the multilateral and the regional trade systems gives rise to the result that, for the same number of direct trade partners, the R&D effort of a country in the multilateral agreement is lower than the R&D effort of a hub but higher than the R&D effort of a spoke. This suggests that a ”core” country within the regional trade system has higher R&D and productivity level than a country with the same number of trade agreements within the multilateral system whereas the opposite is true for a ”periphery” country. Additionally, the paper finds that while multilateral trade liberalization boosts productivity of all countries, regional trade liberalization increases productivity of core economies but may decrease productivity of periphery economies if the level of competition in the new trade partner countries of the periphery economy is ”too high”. Furthermore, the aggregate level of R&D activities within the multilateral trade agreement exceeds that in the star – the simplest representative of the hub-and-spoke trade system.
Estimating Trade Policy Effects with Structural Gravity
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.
Are Stricter Investment Rules Contagious?
We argue that the trend toward international investment agreements (IIAs) with stricter investment rules is driven by competitive diffusion, namely defensive moves of developing countries concerned about foreign direct investment (FDI) diversion in favor of competing host countries. Accounting for spatial dependence in the formation of bilateral investment treaties (BITs) and preferential trade agreements (PTAs) that contain investment provisions, we find that the increase in agreements with stricter provisions on investor-state dispute settlement and pre-establishment national treatment is a contagious process. Specifically, a developing country is more likely to sign an agreement with weak investment provisions if other developing countries that compete for FDI from the same developed country have previously signed agreements with similarly weak provisions. Conversely, contagion in agreements with strong provisions exclusively derives from agreements with strong provisions that other FDI-competing developing countries have previously signed with a specific developed source country of FDI.
