Global Economic Integration: What's New and What's Not?

Ben S. Bernanke at the Federal Reserve Bank of Kansas City's Thirtieth Annual Economic Symposium, Jackson Hole, Wyoming, August 25, 2006.

After a summary of the major trends in gobalization over several centuries, Bernanke said:

"Perhaps the clearest conclusion is that new technologies that reduce the costs of transportation and communication have been a major factor supporting global economic integration. Of course, technological advance is itself affected by the economic incentives for inventive activity; these incentives increase with the size of the market, creating something of a virtuous circle. For example, in the nineteenth century, the high potential return to improving communications between Europe and the United States prompted intensive work to better understand electricity and to improve telegraph technology--efforts that together helped make the trans-Atlantic cable possible.

"A second conclusion from history is that national policy choices may be critical determinants of the extent of international economic integration. Britain's embrace of free trade and free capital flows helped to catalyze international integration in the nineteenth century. Fifteenth-century China provides an opposing example. In the early decades of that century, the Chinese sailed great fleets to the ports of Asia and East Africa, including ships much larger than those that the Europeans were to use later in the voyages of discovery. These expeditions apparently had only limited economic impact, however. Ultimately, internal political struggles led to a curtailment of further Chinese exploration (Findlay, 1992). Evidently, in this case, different choices by political leaders might have led to very different historical outcomes.

"A third observation is that social dislocation, and consequently often social resistance, may result when economies become more open. An important source of dislocation is that--as the principle of comparative advantage suggests--the expansion of trade opportunities tends to change the mix of goods that each country produces and the relative returns to capital and labor. The resulting shifts in the structure of production impose costs on workers and business owners in some industries and thus create a constituency that opposes the process of economic integration. More broadly, increased economic interdependence may also engender opposition by stimulating social or cultural change, or by being perceived as benefiting some groups much more than others.

Barnanke went on to suggest that the same patterns persist today, emphasizing the role of information and communications technologies. He then examines:

What, then, is new about the current episode? Each observer will have his or her own perspective, but, to me, four differences between the current wave" of global economic integration and past episodes seem most important. First, the scale and pace of the current episode is unprecedented. For example, in recent years, global merchandise exports have been above 20 percent of world gross domestic product, compared with about 8 percent in 1913 and less than 15 percent as recently as 1990; and international financial flows have expanded even more quickly.......

"Second, the traditional distinction between the core and the periphery is becoming increasingly less relevant, as the mature industrial economies and the emerging-market economies become more integrated and interdependent. Notably, the nineteenth-century pattern, in which the core exported manufactures to the periphery in exchange for commodities, no longer holds, as an increasing share of world manufacturing capacity is now found in emerging markets......

"Third, production processes are becoming geographically fragmented to an unprecedented degree. Rather than producing goods in a single process in a single location, firms are increasingly breaking the production process into discrete steps and performing each step in whatever location allows them to minimize costs.......

"The final item on my list of what is new about the current episode is that international capital markets have become substantially more mature. Although the net capital flows of a century ago, measured relative to global output, are comparable to those of the present, gross flows today are much larger. Moreover, capital flows now take many more forms than in the past."

He concludes:

"By almost any economically relevant metric, distances have shrunk considerably in recent decades. As a consequence, economically speaking, Wausau and Wuhan are today closer and more interdependent than ever before. Economic and technological changes are likely to shrink effective distances still further in coming years, creating the potential for continued improvements in productivity and living standards and for a reduction in global poverty.

"Further progress in global economic integration should not be taken for granted, however. Geopolitical concerns, including international tensions and the risks of terrorism, already constrain the pace of worldwide economic integration and may do so even more in the future. And, as in the past, the social and political opposition to openness can be strong. Although this opposition has many sources, I have suggested that much of it arises because changes in the patterns of production are likely to threaten the livelihoods of some workers and the profits of some firms, even when these changes lead to greater productivity and output overall. The natural reaction of those so affected is to resist change, for example, by seeking the passage of protectionist measures. The challenge for policymakers is to ensure that the benefits of global economic integration are sufficiently widely shared--for example, by helping displaced workers get the necessary training to take advantage of new opportunities--that a consensus for welfare-enhancing change can be obtained. Building such a consensus may be far from easy, at both the national and the global levels. However, the effort is well worth making, as the potential benefits of increased global economic integration are large indeed."
