1. INTRODUCTION THIS paper considers some of the main developments in globalisation and growth during the 20th century in the context of conflicting claims in the economic literature. The objective is to provide a brief survey of historical experience relevant to the following questions: • Has globalisation promoted ‘divergence big time’? • Is globalisation conducive to faster economic growth? • Will international economic inequality decline in the globalised world of the future?
2. WHAT DRIVES GLOBALISATION? For present purposes globalisation can be thought of as a process of integration of goods and capital markets across the world in which barriers to international trade and foreign investment are reduced. Globalisation can be a result either of technological developments that reduce transport costs, improve information flows etc. or of policy changes that reduce protectionism, liberalise foreign investment rules and make migration easier. Although since the mid-19th century when the steamship, railroad and telegraph arrived, technological change has consistently been pro-globalisation, trends in economic policy have been much more variable. In particular, the interwar period saw a globalisation backlash characterised by trade wars and capital controls. The reversal of these interventions was quite long drawn out although eventually the GATT played a major role; after the demise of the Bretton Woods international monetary system macroeconomic policy favoured international capital mobility. In this respect, the role of the macroeconomic policy trilemma deserves to be noted, namely, that it is possible for a country to have at most two of a fixed exchange rate, independent monetary policy and free international movement of capital. Among the world’s leading economies the choice of what to give up varied over time; before 1914 typically monetary policy was sacrificed, in the 1950s capital mobility was forgone but since 1971 the fixed exchange rate has been abandoned. Globalisation is not easy to measure and these issues cannot be addressed here. Tables 1 and 2 do, however, give a useful sense of the historical experience. The interwar setback to globalisation and the lengthy period before this was reversed, show up in the decline of the ratio of foreign assets to world GDP from 17.4 per cent in 1914 to 4.9 per cent at the end of World War II and the fact that the 1914 ratio was not attained again until 1980. The decline in world trade between 1929 and 1950 from 9.0 to 5.5 per cent was somewhat less dramatic and was made good by the late 1960s. But the most striking feature of these tables is the extent to which globalisation in the modern world goes beyond previous peaks.
