International supply chains require the coordination of numerous activities across multiple countries and firms. This paper develops a theoretical model of supply chains in which the measure of tasks completed within a firm is determined by parameters that define transaction costs and the cost of coordinating more activities within the firm. The structural parameters that govern these costs explain variation in supply chain length as well as cross-country variation in gross-output-to-value-added ratios. The structural parameters are linked to comparative advantage along and across supply chains. The paper provides an analytical treatment of trade and welfare responses to trade cost change in a simple two-country model. To explore the models implications in a richer setting, the model is calibrated to match key observables in East Asia, and the calibrated model is used to evaluate implications of changes in model parameters for trade, welfare, the length of supply chains, and countries relative position within them.

The main message of this report is that if Kazakhstan wants to take advantage of global integration and diversification opportunities, the government needs to improve its trade policy framework, its management, and its regulations. It is also finalizing accession to the World Trade Organization (WTO) while its trade strategy includes a number of free trade agreements to be negotiated. It is an active member of the Central Asia Region Economic Cooperation (CAREC). This report is composed of three policy notes that discuss how to improve the trade policy framework, management, and regulations: note one is on the trade policy framework and recommends joining the WTO on a tariff schedule that is more liberal than Russia’s; note two postulates that to benefit more fully from the WTO membership and future regional or bilateral agreements, the institutional framework for trade policy management will need a clearer strategic vision, better coordination within the government and with private sector, and enhanced human capacity; and note three suggests that for the private sector to benefit from global integration and diversification, the government should ease the burden of regulations that affect trade (non-tariff measures (NTMs)).

Trade is essential for Caribbean countries development and poverty reduction. Given their small market size, they are dependent on exports to produce manufactured products at efficient scale. And given their natural amenities, they rely on tourism as a major spur to economic activity. Trade in the Caribbean thus makes an essential contribution to increasing employment and reducing poverty by supporting growth. At the same time, the high dependence on trade also makes Caribbean economies vulnerable to external shocks. For example, the global financial crisis imposed substantial job losses in sectors such as tourism that the poor rely on for employment. This report employs several different, but complementary, empirical approaches to analyzing the impact of this emerging new trade environment on shared prosperity in the Caribbean. These include the following six topics, with each corresponding to an individual chapter: (i) assessment of the Caribbean s performance in reaping the opportunities offered by the new trade environment; (ii) identification of the main determinants of Caribbean countries trade performance; (iii) discussion of the role of innovation and access to keys services in improving the productivity of exporting firms; (iv) exploration of how regional integration and other trade agreements could boost Caribbean trade performance; (v) firm-level examination of the implications of trade for employment; and (vi) identification of which households are involved in international trade and the implications of trade for their socio-economic status.

There is a large body of research that explores international trade as a source of the dispersion in income levels and growth performances across countries. The trade liberalization policies undertaken between 1950 and 2006 led to an almost 30 fold growth in the volume of international trade. However this increase has not been homogeneous across countries. This study investigates a possible reason that prevents convergence of countries in export performance. It shows that regulatory quality, customs efficiency, quality of infrastructure, and access to finance among other factors increase export performance. Furthermore, it shows that countries that are relatively more constrained in accessing to foreign markets benefit more from improvements in investment climate than the countries with easier foreign market access. Hence attaining a favorable investment climate for private sector development should be an important policy objective for relatively closed economies to achieve convergence in export volumes with countries that have more liberal trade policies.

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.

This paper examines the link between government spending on a public good and pattern of trade in the presence of specialization-based external economies. The results presented in this paper are based on a simple model of an economy that produces one industrial, one agricultural, one public good and a large number of varieties of professional services. It is shown that, when the agricultural and the public goods are non-traded, the country where government spending is relatively large is a net-exporter of varieties of professional services; if varieties of professional services are equally (or more) capital intensive as compared to the industrial good. When the public good and varieties of professional services are non-traded, the country where government spending is relatively large may export the industrial good in exchange for the agricultural good; if the combined capital intensity of professional services and the industrial good is greater than the capital intensity of the agricultural good and the size of specialization-based external economies is sufficiently small.

This paper reports panel gravity estimates of aggregate bilateral trade for 130 countries over the period 1962-96 in which the coefficient of distance is allowed to change over time. In a standard specification in which transport costs are proxied by distance only, it is found paradoxically that the absolute value of the elasticity of bilateral trade to distance has been significantly increasing.The result is attributed to a relatively larger decline in costs independent of distance (such as handling) than in distance-related costs (e.g. oil price). An extended version of the model that controls for these two factors eliminates this positive trend without reversing it. However, when the sample is split into two groups ("rich-rich" and "poor-poor"), the paradox is maintained for the "poor-poor" group. While not conclusive, these results are consistent with the view that poor countries may have been marginalized by the current wave of globalization.

We study a world economy comprising two countries that may differ only in their prior experience in the research lab. Entrepreneurs in each country develop new technologies for varieties of a differentiated product whenever expected profits justify up-front research costs. Research productivity depends upon national stocks of knowledge capital, which accumulate in proportion to local research activity. The countries produce and trade their unique varieties of the differentiated good, as well as a homogeneous, "traditional" product. In this context, we ask whether a country can overcome a late start in research to develop a comparative advantage in the hightechnology sector. We also examine the welfare properties of the equilibrium trajectory and of policies that might be used to reverse a country's fate.
