Dani Rodrik counters the popular idea that national boundaries are becoming increasingly irrelevant:
Geographical distance is as strong a determinant of economic exchange as it was a half-century ago. Even the Internet, it turns out, is not as borderless as it seems: one study found that Americans are much more likely to visit Web sites from countries that are physically close than from countries that are far away, even after controlling for language, income, and many other factors.
The trouble is that we are still in the grasp of the myth of the nation-state’s decline. Political leaders plead impotence, intellectuals dream up implausible global-governance schemes, and the losers increasingly blame immigrants or imports. Talk about re-empowering the nation-state and respectable people run for cover, as if one has proposed reviving the plague.
