Globalization and International Trade
“Globalization” refers to the growing interdependence of countries resulting from the increasing integration of trade, finance, people, and ideas in one global marketplace. International trade and cross-border investment flows are the main elements of this integration. Globalization started after World War II but has accelerated considerably since the mid-1980s, driven by two main factors. One involves technological advances that have lowered the costs of transportation, communication, and computation to the extent that it is often economically feasible for a firm to locate different phases of production in different countries. The other factor has to do with the increasing liberalization of trade and capital markets: more and more governments are refusing to protect their economies from foreign competition or influence through import tariffs and nontariff barriers such as import quotas, export restraints, and legal prohibitions. A number of international institutions established in the wake of World War II—including the World Bank, International Monetary Fund (IMF), and General Agreement on Tariffs and Trade (GATT), succeeded in 1995 by the World Trade Organization (WTO)—have played an 66
important role in promoting free trade in place of protectionism. Empirical evidence suggests that globalization has significantly boosted economic growth in East Asian economies such as Hong Kong (China), the Republic of Korea, and Singapore. But not all developing countries are equally engaged in globalization or in a position to benefit from it. In fact, except for most countries in East Asia and some in Latin America, developing countries have been rather slow to integrate with the world economy. The share of SubSaharan Africa in world trade has declined continuously since the late 1960s, and the share of major oil exporters fell sharply with the drop in oil prices in the early 1980s. Moreover, for countries that are actively engaged in globalization, the benefits come with new risks and challenges. The balance of globalization's costs and benefits for different groups of countries and the world economy is one of the hottest topics in development debates.

12 GLOBALIZATION AND INTERNATIONAL TRADE
stem from the increased access of their producers to larger, international markets. For a national economy that access means an opportunity to benefit from the international division of labor, on the one hand, and the need to face stronger competition in world markets, on the other. Domestic producers produce more efficiently due to their international specialization and the pressure that comes from foreign competition, and consumers enjoy a wider variety of domestic and imported goods at lower prices. In addition, an actively trading country benefits from the new technologies that “spill over” to it from its trading partners, such as through the knowledge embedded in imported production equipment. These technological spillovers are particularly important for developing countries because they give them a chance to catch up more quickly with the developed countries in terms of productivity. Former centrally planned economies, which missed out on many of the benefits of global trade because of their politically imposed isolation from market economies, today aspire to tap into these benefits by reintegrating with the global trading system. But active participation in international trade also entails risks, particularly those associated with the strong competition in international markets. For example, a country runs the risk that some of its
industries—those that are less competitive and adaptable—will be forced out of business. Meanwhile, reliance on foreign suppliers may be considered unacceptable when it comes to industries with a significant role in national security. For...
