New technology such as air transport may have helped propel today's globalization, but the role of such change in leading to globalization should not be overstated. On the other hand, technology in the information age may make it more difficult for politicians to reverse the course of world capitalism. Although globalization is often said to create inequality and economic volatility, historical evidence points, in fact, to economic convergence in living standards among countries that open their economies. Studies have shown tendencies to converge among countries in the Organization of Economic Cooperation and Development, among U.S. states, and among Japanese prefectures. Significantly, economist Jeffrey Williamson found a decreasing gap in living standards among people living in countries participating in the international economy during both periods of global capitalism.
History offers an unambiguous positive correlation between globalization and convergence.
The incidence of financial crises in Asia, Russia, and elsewhere in recent years has also often been treated as novel and as a consequence of globalization. Despite that consensus, the crises are used by critics of globalization to advocate moving away from a more market-based system and toward more interventionism. Thus India is cited as having followed more prudent policies than its East Asian neighbors since its more closed system allowed it to avoid succumbing to the regional financial crisis. The price it has paid for stability, of course, has been enduring poverty. By contrast, Hong Kong has had a volatile economic history but has become one of the wealthiest places on earth.
