WTO Working Papers

The interplay between patents and standards in the information and communication technology (ICT) sector has been intensively debated at international, regional and national levels over the past decades. In essence, the debate is firstly about the extent and impact of patent holdup and holdout in the ICT sector, and then about how to eliminate or reduce these practices.

Trade has been recognized in the 2030 development Agenda as well as in the Addis Ababa Agenda for Action as an important means for the implementation of the Sustainable Development Goals (SDGs).

The WTO's plurilateral Agreement on Government Procurement ("the GPA" or "the Agreement") is an important ongoing success story for the Organization. In March 2012, the GPA Parties completed a comprehensive revision of the Agreement, encompassing both its text and coverage (market access commitments). The revised GPA, the negotiating processes that led to its adoption and coming into force, and the continuing gradual broadening of its membership are of therefore interest for the evolution of the international trading system. The GPA's successful renegotiation, the continuing growth of its membership and its vitality as an instrument of public policy were not achieved through happenstance. The paper discusses a number of specific design features of the GPA that clearly facilitated the successful conclusion of the renegotiation and that, as such, may in the future be relevant to other areas of global trade liberalization. In addition to the Agreement's plurilateral nature, of particular interest are the approach taken with respect to application of the most-favored-nation (MFN) principle in the Agreement; the GPA's continuing strong emphasis on principles of reciprocity in market access concessions; and its approach to special and differential treatment for developing countries, in all of which it differs from approaches that are widely used in other WTO Agreements. Apart from the above, the GPA revision is important for the merging of trade and good governance concerns that it exemplifies. As discussed in the paper, the themes of governance and the sound management of public resources that are treated in the revised Agreement were not afterthoughts to the renegotiation; rather, they permeated the revised text and received focused attention from the Parties in their own right. As well, the GPA has direct implications for investment policy and for domestic economic reforms, and is an important tool of e-commerce. And, the revision has made possible very significant synergies between the GPA and other international instruments and activities in reducing barriers to participation and strengthening governance in public procurement markets. For all these reasons, the revised Agreement is likely to have a wider impact than meets the eye, and well merits the support and attention that it has received from the participating WTO Member governments.

Trade costs such as applied tariffs, transportation and insurance costs are amplified as they pass through the multiple production steps associated with modern supply chains. This socalled "cascade effect" arises since trade costs accumulate as intermediate goods are imported and then re-exported further downstream, going through different processing nodes before reaching the final consumer. Moreover, the financial impact of these trade costs is magnified in the "trade in tasks" rationale which governs global value chains (GVCs). Specialised processing firms need to recoup the associated trade cost applying to the full value of the good from the smaller fraction of value-added created at each consecutive productive stage. This large relative weight of transaction expenses on the profitability of individual business operations explains why trade along GVCs is particularly exposed to trade costs. The paper reviews the implications of trade costs on competitiveness at industry, national and global levels. The financial implications of trade costs at firm and sectoral level are based on trade in value-added data for 2011. The multilateral welfare effects of reducing discrete trade costs are identified using a network analysis approach, which goes beyond the traditional bilateral dimension of international trade and identifies where trade facilitation investment would have the highest social returns from a GVC perspective. The authors conclude that while the direct benefits of trade facilitation will be proportionally higher for those countries that are not well integrated into international trade because of their high trade costs, the global benefits of trade facilitation investments will also be high if they are undertaken by key traders that lie at the core of global value chains.

After a decade of negotiations and additional preparatory work, the WTO Trade Facilitation Agreement (TFA) is poised to enter into force. It promises to streamline and substantially prune the red tape that all too often slows and impedes international commerce - thereby significantly reducing both cost and time needed to do business across borders. The paper chronicles the path from the conclusion of the talks at the 2013 Bali Ministerial Conference to the present day as we prepare for the Agreement to take effect. It reviews the state of the ratification process, analyses implementation schedules and outlines work still to be done. The study shows that the emerging application of the TFA, like its negotiation, has once again confounded the sceptics – who first doubted that a TF Agreement would see the light of day and then questioned if it would ever be put into practice. While plenty remains to be done to implement the TFA across the full WTO membership, its entry into force is set to happen – a valedictory moment.

This paper reviews the different types of provisions explicitly addressing small and medium enterprises (SMEs), including micro firms (MSMEs), in regional trade agreements (RTAs). The analysis covers the 270 RTAs currently in force and notified to the WTO as of April 2016. The analysis shows that half of all the notified RTAs, namely 136 agreements, incorporate at least one provision mentioning explicitly SMEs. These SMEs-related provisions are highly heterogeneous and differ in terms of location in the RTA, language, scope and commitments. Many of the SMEs related provisions are only found in a single or couple of RTAs. A limited but increasing number of RTAs incorporate specific provisions in dedicated articles or even chapters on SMEs. Although the number of detailed SMEs-related provisions included in a given RTA has tended to increase in recent years, most SMEs-related provisions remain couched in best endeavour language. The two most common categories of SMEs-related provisions found in RTAs are provisions (1) promoting cooperation on SMEs and (2) specifying that SMEs and/or programs supporting SMEs are not covered by the RTAs' obligations provisions. Other types of SMEs-related provisions, incorporated in a limited number of RTAs, refer, inter alia, to government procurement, trade facilitation, electronic commerce, intellectual property, or transparency.

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.

The objective of this manuscript is to serve as a practical guide for evaluation of the general equilibrium (GE) effects of trade policy using the structural gravity model. We try to achieve this objective in four steps. First, we focus on the original Armington-CES gravity model to offer a deep analysis of the structural relationships underlying the general equilibrium gravity system, and how they can be exploited to make trade policy inferences. Second, we present and discuss a series of indexes that can be used to summarize the GE effects of trade policy. Third, we summarize the standard procedures to perform counterfactual analysis with the gravity model, and we outline recent methods to obtain theory-consistent GE effects of trade policy. Finally, we demonstrate how gravity can be integrated with a broader class of general equilibrium models by nesting the Armington-CES model within a dynamic production superstructure with capital accumulation.

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.
