WTO Working Papers

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.

The unbundling of trade across regions offers unique opportunities for SMEs to integrate into global trade notably through their involvement into supply-chains. With supplychains shifting and expanding into new regions of the world, the challenge for SMEs to accessing financing remains an important one; in many developing and emerging market economies, the capacity of the local financial sector to support new traders is limited. Moreover, after the financial crisis, several global banks have "retrenched", for various reasons. In this context, supply-chain finance arrangements, and other alternative forms of financing such as through factoring, have proven increasingly popular among traders. This paper shows that factoring has a positive effect in allowing SMEs to access international trade, in countries in which it is available. Factoring also appears to be employed by firms involved in global supply chains. We employ for the first time data on factoring from Factor Chain International (FCI), the most extensive dataset on factoring available at the moment, for the period of 2008-2015. Using an instrumentation strategy we identify a strong, stable effect of factoring on SMEs access to capital for some of the main traders in the world.

The average international trade transaction is subject to numerous procedural and documentation requirements, which add to the costs of doing business as an importer or exporter and also use up scarce government resources. While these requirements can be necessary to fulfil policy objectives, questions are often raised about why and how they are implemented. The Trade Facilitation Agreement (TFA), adopted by WTO Members in 2014, seeks to expedite the movement, release and clearance of goods across borders and reduce these trade transaction costs - by an average of 14.3 per cent as estimated by the 2015 World Trade Report. At the same time, many WTO Agreements already contain provisions aimed at facilitating trade procedures and avoiding unnecessary costs. The Agreement on Technical Barriers to Trade (the TBT Agreement) is one of these: its provisions on transparency and conformity assessment procedures, some of which are applied at the border, are of particular relevance in this context. The TFA and TBT Agreements are in fact complementary, with the TFA introducing some new requirements/recommendations, which are likely to apply to certain TBT measures. This paper maps out the linkages between these two Agreements. It does so with a view to informing TBT officials of the requirements and best practices emerging in the trade facilitation area as well as raising awareness amongst trade/customs officials of existing rules and evolving practices in the TBT area. The 2015 World Trade Report refers to “border agency cooperation” as the main TFA implementation challenge identified by developing countries and also points to the importance of cooperation and coordination between ministries as one of the main success factors. Considering that a significant share of import/export procedures and controls arise from the implementation of TBT measures, a better understanding of the linkages between the TFA and the TBT Agreement (as well as other relevant WTO Agreements such as the SPS Agreement) will be crucial for effective implementation. It will also contribute to more streamlined technical assistance activities and raise awareness among TBT officials of the opportunities generated by trade facilitation projects. The procedures and practices of the WTO TBT Committee, especially with regards to transparency and specific trade concerns, could also be of interest to the future TFA Committee, as it embarks on its task of furthering the implementation of the TFA. All these in turn will help reap the expected benefits of the new Trade Facilitation Agreement.

The GATS does not offer a definition of "services", but services need to be identified and classified for the operation of the Agreement, especially for the scheduling of specific commitments on market access and national treatment. There is no obligation on WTO Members to use any particular classification system in undertaking commitments. Nevertheless, an informal document produced for the services negotiation during the Uruguay Round, the Services Sectoral Classification List (W/120), was used and continues to be used as the principal guiding classification system, not only in the WTO, but also in bilateral and plurilateral services trade negotiations outside of the WTO. WTO jurisprudence has also noted the role of W/120 in the determination of sectoral coverage of GATS commitments. However, services classification does not receive enough attention it deserves. This paper attempts to make contribution by providing an overview of services classification and highlighting its relevance to both trade negotiations and WTO dispute settlement. It consists of four sections. Section I reviews how a services classification system was introduced into the multilateral trading system and describes the main features of W120. Section II takes a closer look at some aspects of the classification system, drawing attention to challenges in its application, which arise from inter alia services with multiple end-uses, overlaps between sectors, and the issue of "new services". Section III considers the implications of classification on GATS commitments by examining a number of WTO dispute settlement cases. Section IV concludes. In conclusion, the paper underlines the importance of services classification in assisting governments in clearly and accurately undertaking commitments. It also notes that WTO Members have taken or suggested various pragmatic approaches to addressing challenges in the application of the current services classification system. The proposed approaches again highlight the role of classification in ensuring the clarity, certainty and predictability of specific commitments in services.

This paper investigates whether TBT provisions included in RTAs differ from those under the WTO TBT Agreement, and, if they do, whether they entail broader commitments. Our analysis covers 238 RTAs, of which 171 include at least one provision, and focuses on the provisions on technical regulations, conformity assessment procedures, transparency, dispute settlement, marking and labelling and sector-specific commitments. We find that all RTAs signed since 2010 systematically include TBT provisions and that the most frequent provisions are those referring to the TBT Agreement and transparency. Moreover, even if there are RTAs that include new or broader commitments than the TBT Agreement, our study shows that their number remains very limited. For instance, relatively few RTAs have included provisions to better implement WTO provisions in the area of transparency or provisions requiring the equivalence or harmonization of technical regulations among the parties or even the recognition of conformity assessment results. RTAs with a dispute settlement provision that applies exclusively to TBT issues are also very few. These RTAs give in general exclusive jurisdiction to the WTO DSM over TBT related disputes. Finally, also only a minority of RTAs include provisions on new issues such as marking and labelling or sector-specific provisions, typically for electric and electronic products, pharmaceuticals or vehicles.

In 2003, the WTO General Council decided to provide an additional legal pathway for WTO Members with insufficient or no manufacturing capacities in the pharmaceutical sector to access medicines. Two years later, in 2005, WTO Members unanimously agreed to give this mechanism, often referred to as the "Paragraph 6 System", a permanent legal status when they adopted the Protocol Amending the TRIPS Agreement. The implementation and use of the additional pro-public health flexibilities provided by the System is optional, not mandatory. To take advantage of them, as of July 2015, 51 WTO Members have adopted specific implementing measures with a variable degree of detail and complexity which incorporate the Paragraph 6 System in their respective legal frameworks and provide the basis for them to act either as exporter or as importers, or as both. This represents almost a third of the WTO Membership, and the predominant bulk of existing pharmaceutical exporters. Given that, unlike other flexibilities in the TRIPS Agreement, the Paragraph 6 System was devised as a new mechanism without previous domestic experience to draw upon, there seems to be an exceptional need for an in-depth discussion of how it has been implemented at country level to which this paper attempts to respond. There is, indeed, often limited knowledge in the policy and procurement communities about the wide range of specific measures that have been introduced in many major exporters of medicines and the importance of this information both from a practical point of view, to facilitate exports of needed medicines, and from a policy point of view, to understand the implementation of this novel tool for access to medicines. To contribute to a better understanding of how the System has been implemented in practice, this paper surveys domestic measures that WTO Members have put in place. By doing so, it can inform the broader dialogue about access to medicines and provide practical information for procurement programmes. It can also put a valuable source of information and inspiration at the disposal of those Members who are yet in the process of considering whether and how best to implement the Paragraph 6 System in their domestic legal framework. While the survey illustrates that a robust framework supportive of the export of generic medicines to meet public health needs has been put in place by a significant number of WTO Members, there is an obvious need to move a step forward and engage in a substantive review of the System, including if and how better, more frequent use could be made of it. To conclude, the paper therefore offers some elements for reflection regarding the way forward in order to support the functioning of the Paragraph 6 System.

This paper studies the effects of trade policy uncertainty on the extensive and the intensive margins of trade for a sample of 149 exporters at the HS6 digit level. We measure trade policy uncertainty as the gap between binding tariff commitments under trade agreements (multilateral and regional agreements) and applied tariffs- what is also known as tariffs’ water. Our results show that trade policy uncertainty is an important barrier to export. On average the elimination of water increases the probability of exporting by 12 percent. A one percent decrease of water also increases export volumes by one percent. We also find that the negative impact of trade policy uncertainty is higher for countries with low quality of institutions and in the presence of global value chains. Finally, our findings show that on average trade policy uncertainty is equivalent to a level of tariffs between 1.7 and 8.7 percentage points.

This paper analyses the role of services in international trade through the lens of global value chains (GVCs). Services account for more than 70% of world GDP but only for around 20% of world trade in balance of payments terms. In value added terms, accounting for services embodied in exported goods, services account for 40% of world trade. Services industries increasingly produce in networked or "fragmented" arrangements. The paper lays out conceptual and measurement issues related to services networks and provides evidence based on trade in value added statistics and on a case study on the film industry. In contrast to goods value chains, services networks appear less fragmented internationally based on trade in value added statistics and survey evidence. However, to better capture the international services fragmentation, advances in statistics by enterprise characteristics and by mode of supply, i.e. taking into account the movement of labour and capital, are required.

The WTO’s plurilateral Information Technology Agreement (ITA) reduced tariffs to zero on many IT products. This paper presents a comprehensive study of its trade impacts by incorporating recent insights from both the global value chain (GVC) and time in trade literatures. Inserting tariffs directly into the gravity equation breaks the ITAs impact down into four layers. Import demand elasticities are found to be non-linear: Tariff reduction (layer 1) has relatively small impacts, while complete tariff elimination (layer 2) has high impacts, especially for intermediate goods. Beyond that, ITA accession has positive non-tariff effects on both imports (layer 3) and exports (layer 4). These commitment effects suggest that higher trade policy certainty affects investment and sourcing decisions in favour of signatories: Their ITA exports performed better relative to other ICT and machinery exports, unlike non-members. But “passive signatories” – which joined mainly as a by-product of a larger policy objective – reaped the most benefits. Featuring a smaller ITA sector upon accession, their final good exports increased also in absolute terms due to downstream GVC integration. However, such impacts are strongly heterogeneous with respect to countries’ geographical remoteness, education levels, business environment and institutions. China stands out with especially strong post-accession export increases, also extending to intermediate goods.

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.

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 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.

Bangladesh's international image is not as a popular tourism destination, and many people might be surprised to learn it has three World Heritage sites, including the Sundarbans tiger reserves. Moreover, it is part of important travel circuits for cultural and religious tourism, and has demonstrated potential for sports tourism. The objective of this working paper is to critically test the assertion that pro-poor "green" tourism is one of the best development options for the majority of least developed countries (LDCs) -- a challenging task in Bangladesh in the face of the country's success as an exporter of readymade garments -- by comparing tourism to the available alternatives with regard to the crucial government priorities of export diversification, employment generation and the "green economy". It is well-known that Bangladesh is under strong pressure to diversify its exports, to generate new employment (especially in rural areas), and to respond to critical environmental issues. The government has identified over 30 "thrust sectors" (including tourism) to help address these challenges, but otherwise tourism is rarely mentioned as a major trade and development option for Bangladesh. Within the limitations of data availability, this working paper reaches the conclusion that greater efforts to develop "green" tourism would be highly beneficial for facilitating rural development, environmental and cultural protection, gender equality, and export diversification in services. The most obvious current impediments are inadequate infrastructure, lack of investment and (typically election year) political conflict, but behind these factors appear to be a serious lack of stakeholder coordination, insufficient regulatory and administrative transparency and coherence, as well as some government reluctance to relinquish greater commercial autonomy in tourism to the private sector. This paper offers extensive analysis and some suggestions to help address the impediments, including the recommendation to create a Bangladesh Tourism Stakeholders Forum.

Most international commerce is carried out by multinational firms, which use their foreign affiliates for the majority of their foreign sales. In this paper, I examine the determinants of multinational firms’ location and production decisions and the welfare implications of multinational production. The few existing quantitative general equilibrium models that incorporate multinational firms achieve tractability by assuming away export platforms – i.e. they do not allow foreign affiliates of multinationals to export – or by ignoring fixed costs associated with foreign investment. I develop a quantifiable multi-country general equilibrium model, which tractably handles multinational firms that engage in export platform sales and that face fixed costs of foreign investment. I first estimate the model using German firm-level data to uncover the size and nature of costs of multinational enterprise and show that fixed costs of foreign investment are large. Second, I calibrate the model to data on trade and multinational production for twelve European and North American countries. Counterfactual results reveal that multinationals play an important role in transmitting technological improvements to foreign countries as they can jump the barriers to international trade; I find that a twenty percent increase in the productivity of US firms leads to welfare gains in foreign countries an order of magnitude larger than in a world in which multinational production is disallowed. I demonstrate the usefulness of the model for current policy analysis by studying the pending Canada-EU trade and investment agreement; I find that a twenty percent drop in the barriers to foreign production between the signatories would divert about seven percent of the production of EU multinationals from the US to Canada.

How do information frictions distort international trade? This paper exploits a unique historical experiment to estimate the magnitude of these distortions: the establishment of the transatlantic telegraph connection in 1866. I use a newly collected data set based on historical newspaper records that provides daily data on information flows across the Atlantic together with detailed, daily information on prices and trade flows of cotton. Information frictions result in large and volatile deviations from the Law of One Price. What is more, the elimination of information frictions has real effects: Exports respond to information about foreign demand shocks. Average trade flows increase after the telegraph and become more volatile, providing a more efficient response to demand shocks. I build a model of international trade that can explain the empirical evidence. In the model, exporters use the latest news about a foreign market to forecast expected selling prices when their exports arrive at the destination Their forecast error is smaller and less volatile the more recent the available information. I estimate the welfare gains from information transmission through the telegraph to be roughly equivalent to those from abolishing a 6% ad valorem tariff.

The United Nations' post--2015- development agenda is taking shape. Like its predecessor the Millennium Development Goals, the post--2015- agenda will reshape development policy priorities for governments and non-governmental actors alike, in many cases galvanising new attention, thinking, and financing to tackle the priorities it identifies. This essay reviews the historical and ongoing role played by trade in sustained high growth and human development progress, and makes the case that the post--2015- development agenda should include considerations related to trade rules and supply-side capacity. Given the strong links between trade-led growth, economic upgrading, and poverty reduction, the paper argues that trade led economic growth must be prioritised in the post--2015- development agenda.

The paper builds a typology of value-added traders according to their economic and trade policy characteristics. In the process, it defines clusters of countries according to the multidimensional criteria defined by value-added, economic and trade policy indicators. A second approach focuses on the relationships existing between the variables themselves, using multicriteria and graph analysis. Natural resources endowments, on the one hand, and services orientation, on the other one, are among the most determinant variables for defining Trade in Value Added (TiVA) clusters. The level of economic development remains a crucial determinant of the TiVA profile as is the size of the economy, even if not as important as initially expected. Proactive GVC up-grading strategies, such as investments in ICT and R&D tend to foster a higher foreign content in exports, compensating the lower domestic margin by higher volumes. Inwardoriented protectionist policies are not particularly successful in exporting higher share of domestic content, except in services exports; but in this case, export volumes remain marginal.

The paper chronicles the negotiating history of the recently concluded Trade Facilitation Accord. Analysing the various stages of the decade-long effort to get the Agreement off the ground, it examines what was at stake in the negotiations, how they evolved and why they finally succeeded - despite many obstacles and detours along the way. The study also suggests ways in which the exercise has broken new ground – for Trade Facilitation rule-making at the global level, for how WTO Members negotiate agreements, and for the world trading system as a whole.

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.

Trade finance, particularly in the form of short-term, self-liquidating letters of credit and the like, has received relatively favourable treatment regarding capital adequacy and liquidity under Basel III, the new international prudential framework. However, concerns have been expressed over the potential” unintended consequences” of applying the newly created leverage ratio to these instruments, notably for developing countries’ trade. This paper offers a relatively simple model approach showing the conditions under which the initially proposed 100% leverage tax on non-leveraged activities such as letters of credit would reduce their natural attractiveness relative to higher-risk, less collateralized assets, which may stand in the balance sheet of banks. Under these conditions, the model shows that leverage ratio may nullify in part the effect of the low capital ratio that is commensurate to the low risk of such instruments. The decision by the Basel committee on 12 January 2014 to reduce the leverage ratio seems to be justified by the analytical framework developed in this paper.

LDCs' trade patterns changed in the past decade, thanks to the rebalancing of global demand towards large emerging countries and the resulting cycle of high international commodity prices. This process led to a wider geographical diversification of LDCs' exports but contributed also to a greater reliance on those highly priced commodities. Notwithstanding some progress in market and product diversification — including services — LDCs remain particularly vulnerable to external shocks. With the exception of 2006-2008, the LDCs as a group have systematically recorded a trade deficit. The 2008-2009 global crisis and the bumpy recovery which followed illustrate the volatility of the recent trends. In such a perspective, renewed efforts towards extensive product diversification are called for. Fostering diversification has been supported for many years by preferential market access to developed countries; more recently, emerging countries have also been granting such preferences to LDCs products. Preferential market access remains relevant, but is not sufficient to improve the supply-side capabilities. The new business model related to global value chains (GVC) offers new opportunities to LDCs for export diversification. But GVC participation cannot materialize without a proper trade environment. Some of the main obstacles for joining GVCs are the high transaction costs in importing the necessary inputs and exporting the processed goods. Active trade facilitation programmes, such as those identified during the Fourth Global Review of Aid for Trade in July 2013 offer new options to LDCs for joining GVCs. For those LDCs that have already been able to join these global production network, up-grading towards higher "value-added" activities requires more encompassing horizontal policies.

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.

This paper deals with claims, recently raised in various circles, that structural faults in the General Agreement on Trade in Services (GATS) have prevented WTO Members from advancing services liberalization under the Agreement. The GATS is generally associated in this context with a bottom-up (positive-list) scheduling approach where the sectors on which trade commitments are undertaken are selected individually. This is claimed to be less efficient, in terms of liberalization effects, than alternative approaches under which everything is considered to be fully committed unless specifically excluded (top-down or negative listing). However, a closer look at services negotiations conducted in various settings, including the Doha-Round process, WTO accession cases and different types of regional trade agreements, suggests that such structural issues have limited, if any, impact on the results achieved. What ultimately matters are not negotiating or scheduling techniques, but the political impetus that the governments concerned are ready to generate.

The WTO TBT Agreement obliges governments to use international standards as a basis for regulation, yet leaves a degree of flexibility with respect to the choice of standard, and the manner of its use. This interplay between obligation and flexibility has given rise to tension in various fora of the WTO. This paper brings together these three distinct strands of WTO work to illustrate core aspects of the international standards debate at the WTO. In our analysis we first briefly outline the nature of the discipline in the TBT Agreement itself; next, we describe where and how the discussion arises in the WTO; and, finally, explore some implications of governance of international standard setting. We propose that greater regulatory alignment could be achieved through a renewed focus on the procedures of setting international standards (the how), and greater emphasis on robust technical/scientific underpinnings of such standards (the what).

This paper analyses the trade effects of restrictive product standards on the margins of trade for a large panel of French firms. To focus on restrictive product standards only, we use a new database compiling the list of measures that have been raised as concerns in dedicated committees of the WTO. We restrict our analysis to the subset of Sanitary and Phyto-Sanitary (SPS) regulatory measures and analyse the effects of product standards on three variables: (i) probability to export and to exit the export market (firm-product extensive margins), (ii) value exported (firm-product intensive margin) and (iii) export prices. In particular we study whether firms size, market shares and export orientation modify the effect of SPS measures. We find that SPS measures discourage exports. We also find a negative effect of SPS imposition on the intensive margins of trade.
