How flat is the world?

By | June 9, 2011

The Economist reviews a book, World 3.0, by Pankaj Ghemawat of IESE Business School in Spain:

Mr Ghemawat points out that many indicators of global integration are surprisingly low. Only 2% of students are at universities outside their home countries; and only 3% of people live outside their country of birth. Only 7% of rice is traded across borders. Only 7% of directors of S&P 500 companies are foreigners—and, according to a study a few years ago, less than 1% of all American companies have any foreign operations. Exports are equivalent to only 20% of global GDP. Some of the most vital arteries of globalisation are badly clogged: air travel is restricted by bilateral treaties and ocean shipping is dominated by cartels.

Far from “ripping through people’s lives”, as Arundhati Roy, an Indian writer, claims, globalisation is shaped by familiar things, such as distance and cultural ties. Mr Ghemawat argues that two otherwise identical countries will engage in 42% more trade if they share a common language than if they do not, 47% more if both belong to a trading block, 114% more if they have a common currency and 188% more if they have a common colonial past.

What about the “new economy” of free-flowing capital and borderless information? Here Mr Ghemawat’s figures are even more striking. Foreign direct investment (FDI) accounts for only 9% of all fixed investment. Less than 20% of venture capital is deployed outside the fund’s home country. Only 20% of shares traded on stockmarkets are owned by foreign investors. Less than 20% of internet traffic crosses national borders.

You really should read the whole thing here.
