WTO Working Papers

Trade finance has received special attention during the financial crisis as one of the potential culprits for the great trade collapse. Several researchers have used micro level data to establish the link between trade finance and trade, especially so during the financial crisis, and have found diverting results. This paper analyses the effect of trade credit on trade on a macro level through a whole cycle. We employ Berne Union data on export credit insurance, the most extensive dataset on trade credits available at the moment, for the period of 2005--2011-. Using an instrumentation strategy we can identify a significantly positive effect of insured trade credit, as a proxy for trade credits, on trade. The effect of insured trade credit on trade is very strong and remains stable over the cycle, not varying between crisis and non-crisis periods.

In a rapidly changing trade environment, marked by economic slowdown and impasse in the Doha Round, the success of the WTO in promoting and legitimizing the rules-based multilateral trading system rests, to a large extent, on maintaining effective relations with civil society, including non-governmental organisations. This paper provides an overview of the WTO's rules and practices for transparency and engagement with NGOs. First, it looks at both internal and external transparency. Second, it deals with how the WTO engages with civil society and illustrates how this has evolved over time. Third, it looks at how NGOs and civil society contribute to the dispute settlement process. In concluding, it explores whether there is scope for enhancing the WTO's current practices for engagement with NGOs, and if so how. It also offers some suggestions on how NGOs can render the WTO more accountable to the public. One area in which the WTO's practices for transparency and channels of engagement with civil society actors has evolved considerably is dispute settlement. Although only WTO members can bring a dispute to the WTO, the practice of opening hearings to the public, upon the parties' request, and inviting contributions from non-members, including NGOs, shows to what extent WTO transparency and engagement with civil society have improved in recent times. In particular, NGOs have assisted parties to a dispute prepare their briefs. This has included annexing studies to the parties's submissions, submitting amicus curiae briefs, and supporting the panel as experts under Article 13 of the WTO's Dispute Settlement Understanding (DSU). Forging links with civil society is a formidable task for any intergovernmental organization; at issue are the rights of governments to set WTO policy and the need to respect the voices of those without a vote. Although the WTO's rules for engagement with civil society based on Article V:2 of the Marrakesh Agreement and further elaborated in the 1996 Guidelines have not been updated, the actual practices for engagement have evolved considerably over time and it is likely that they will continue to be improved upon in the future.

We analyse the degree of preference utilization in four major importing countries (Australia, Canada, EU and US) and provide evidence that preferences are more widely used than previously thought. For Australia and Canada, we have obtained a new dataset on imports by preferential regime that has so far not been publicly available. For the EU and US, we make use of more disaggregated data than previously used in the literature. We empirically test what determines utilization rates. In line with previous studies, we find that utilization increases with both the preferential margin and the volume of exports, suggesting that using preferences can be costly. However, we also find that utilization rates are often very high, even for very small preferential margins and/or very small trade flows, which contradicts numerous estimates that average compliance costs are as high as 2-6%. We extend the existing literature in relation to both data and methodological issues. In particular, we construct "pseudo transaction-level" data that allows us to assess more precisely when available preferences are utilized. Using this methodology, we obtain a more realistic estimate of what determines utilization. Rather than constituting a percentage share of the trade value, our findings indicate that utilization costs involve an important fixed cost element. We provide estimates for such fixed costs, which appear to be in the range of USD 14 to USD 1,500.

The paper reviews a number of issues related to the use of currencies in international trade, more than one decade after the introduction of the euro and shortly after steps taken by the Chinese authorities to liberalize the use of the RMB in off-shore markets. Trade is an important factor in establishing a currency as an international currency, notably by fulfilling the transaction/medium of exchange and unit of account motives of currency demand. A well prepared liberalization of currency use for international trade and foreign direct investment transactions can even be helpful in achieving the international investment and reserve currency status. While in the distant past the later was also linked to preponderance of a country in trade markets, it is now linked to the prevalence of the currency in international financial transactions, which supposes that the country in question engages at least partly in some liberalization of capital account transactions. This paper shows theoretical and practical reasons explaining the current dominance of the US dollar and the euro in the invoicing of international trade. There is little doubt, though, that in the medium-to-long term the RMB will become a major currency of settlement in international trade. This is not only the current direction of government policy but also that of markets, as evidenced by the rapid expansion of off-shore trade payments in that currency. In the meantime, though, the US dollar and the euro are enjoying a nearduopoly as settlement and invoicing currencies in international trade. The stability of this duopoly is enhanced by a number of factors recently highlighted by economic analysis: coalescing, "thick externalities" and scarcity of international currencies are useful to explain that, until such time that RMB payments match at least the share of China in global trade, the US dollar and of the euro will remain the main currencies in the invoicing and payment of international trade. Section 1 looks at the factors that determine the use of currencies in the invoicing and settlement of international trade. Section 2 looks at the actual reality of currency use for international trade flows, and short-term prospects for the development of a possible alternative to the use of the US dollar and the euro (in particular in Asia), the RMB.

This paper studies the relationship between export policy and food prices. We show that, when individuals are loss averse, food exporters may use trade policy to shield the domestic economy from large price shocks. This creates a complementarity between the price of food in international markets and export policy. Specifically, unilateral actions by exporting countries give rise to a "multiplier effect": when a shock in the international food market drives up (down) its price, governments respond by imposing export restrictions (subsidies), thus exacerbating the initial shock and soliciting further export activism. We test this theory with a new dataset that comprises monthly information on trade measures across 125 countries and 29 food products for the period 2008-10, finding evidence of a multiplier effect. Global restrictions in a product (i.e. the share of international trade covered by export restrictions) are positively correlated with the probability of imposing a new export restriction on that product, especially for staple foods. Large exporters are found to be more reactive to restrictive measures, suggesting that the multiplier effect is mostly driven by this group. Finally, we estimate that a 1 per cent surge in global restrictions increased international food prices by 1.1 per cent on average during 2008-10. These findings contribute to inform the broader debate on the proper regulation of export policy within the multilateral trading system.

We study immigration policy in a small receiving economy under self-selection of migrants. We show that a non-discriminatory immigration policy choice affects and is affected by the migratory decisions of skilled and unskilled foreign workers. From this interaction multiple equilibria may arise, which are driven by the natives' expectations on the welfare effects of immigration. In particular, pessimistic (optimistic) beliefs induce a country to impose higher (lower) barriers to immigration, which crowd out (crowd in) skilled migrants and thus confirm initial beliefs. This self-fulfilling mechanism sustains the endogenous formation of an anti or pro-immigration prejudice. We discuss how the adoption of a skill-selective policy affects this result.

It has become increasingly common to produce goods in a number of geographically dispersed stages linked by international trade. This tendency, known by names such as “production fragmentation”, “processing trade”, and “vertical specialization”, has important implications for the analysis of non-tariff measures (NTMs) and trade facilitation. First, different types of NTMs or trade facilitation issues are naturally associated with different stages in the movement of goods. Different price gaps can be assigned to these stages, making it possible to decompose the overall amount of distortion and to prioritize the policies with the largest potential efficiency gains. Second, NTMs may accumulate in long supply chains, implying that their trade-distorting effects are greater for goods produced in a fragmented manner than for goods with simple production processes. There is evidence that trade costs are more important for high technology goods or goods undergoing several stages of processing. Issues with product standards may be particularly important for goods with long supply chains. The link between NTMs and supply chains also has implications for economic development and for the relationship between liberalization in services and goods.

The WTO's Dispute Settlement Mechanism (DSM) has been hailed as a fundamental aspect of the Multilateral Trading System for developing countries. At the same time developing countries face many challenges to ensure their effective participation in the mechanism. This paper presents statistical evidence of how Latin-American countries have been very active in their use of the DSM, especially when their use of the mechanism is compared to their participation in world trade. This paper also analyses why, to a large extent, Latin American countries have overcome the challenges of participating in the DSM; and have done so by coming up with innovative and creative solutions, without deviating from the guidelines established by WTO rules.

Policy uncertainty can delay investment and reduce the response to policy change. I provide theoretical and novel quantitative evidence for these effects by focusing on trade policy, a ubiquitous but often overlooked source of uncertainty, when a firm's cost of export market entry is sunk. While an explicit purpose of the World Trade Organization (WTO) is to secure long term market access, little theoretical and empirical work analyzes the value of WTO institutions for reducing uncertainty for prospective exporters. Within a dynamic model of heterogeneous firms, I show that trade policy uncertainty will delay the entry of exporters into new markets and make them less responsive to applied tariff reductions. Policy instruments that reduce or eliminate uncertainty such as binding trade policy commitments at the WTO can increase entry even when applied protection is unchanged. I test the model using a disaggregated and detailed dataset of product level Australian imports in 2004 and 2006. I use the variation in tariffs and binding commitments across countries, products and time, to construct model-consistent measures of uncertainty. The estimates indicate that lower WTO commitments increase entry. Reducing trade policy uncertainty is at least as effective quantitatively as unilateral applied tariff reductions for Australia. These results illuminate and quantify an important new channel for trade creation in the world trade system.

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
