How high were import tariffs when GATT participants began negotiations to reduce them in 1947? Establishing this starting point is key to determining how successful the GATT has been in bringing down trade barriers. If the average tariff level was about 40 percent, as commonly reported, the implied early tariff reductions were substantial, but this number has never been verified. This paper examines the evidence on tariff levels in the late 1940s and early 1950s and finds that the average tariff level going into the first Geneva Round of 1947 was about 22 percent. It also find that tariffs fell by relatively more in the late 1940s and early 1950s for a core group of GATT participants (the United States, United Kingdom, Canada and Australia) than they did for many other important countries, including the set of other (non-core) GATT participants.

The emergence of global value chains (GVCs) and their rapid expansion over the past two decades has transformed the global trade environment. GVCs involve task-based trade across multiple stages of the production process that take place across a number of different countries, in which multiple inputs and exports of intermediate goods and services are necessary to produce a final good, which may also be exported. GVC-oriented trade is seen to offer significant opportunities for developing countries, especially smaller ones, to benefit from global integration by changing the nature of competitiveness. With competition for GVC investment taking place in a truly global market, factor competitiveness relative to other countries matters a lot. In this context, the purpose of this note is to shed some light for policymakers, in this case specifically in the Southern African Customs Union (SACU) countries, on where to focus efforts to drive competitiveness for GVC participation. This is a data-intensive exercise that requires indicators to represent underlying capabilities, disaggregated international trade data, and finally, a classification of which products are likely to be trade within GVCs.

This report reviews the status of Maghreb countries' economic integration with the world, with the Arab world, and within the Maghreb itself. It focuses on trade in goods and services, labor and capital flows, financial integration and cross-border infrastructure integration. It discusses the potential benefits of and key constraints to greater integration. The focus on trade liberalization with the European Union (EU) provides an opportunity for individual Maghreb countries to lock in policies that would eventually help them harmonize policies within their own region. The same argument can be made regarding accession to the World Trade Organization (WTO). The Maghreb countries would reap significant additional benefits if, in parallel to reforms undertaken to improve trade liberalization with Europe, they improved conditions for streamlined trade among themselves. There is significant potential for trade in services in the financial sector, transportation and logistics, and communications and information, among other sectors. According to some studies, comprehensive services reforms that involve increased competition and regulatory streamlining would yield benefits that are at least twice the magnitude of those achieved through tariff removal alone.
