Which Parts of Globalization Matter for Catch-up Growth?
Economists devote too much attention to international flows of goods and services and not enough to international flows of ideas. Traditional trade flows are an imperfect substitute for flows of the underlying ideas. The simplest textbook trade model shows that a welfare-enhancing move toward freer flows of ideas should be associated with a reduction in conventional trade. The large quantitative effect from the flow of ideas is evident in the second half of the 20th century as the life expectancies in poor and rich countries began to converge. Another example comes from China, where authorities dramatically reduced accident rates by adopting rules of civil aviation that were developed in the United States. All economists, including trade economists, would be better equipped to talk about international flows of technologies and rules if they adopted a consistent vocabulary based on the concepts of nonrivalry and excludability. An analysis of the interaction between rules and technologies may help explain important puzzles such as why private firms have successfully diffused some technologies (mobile telephony) but not others (safe municipal water.)
Jagdish Bhagwati on Development Aid
In reviewing Dambisa Moyo's Dead Aid in Foreign Affairs, Jagdish Bhagwati takes an interesting look at the history of development aid. He traces the changes in the way economists viewed aid as well as changes in the tactics used by aid advocates. He goes on to note that while many development debates are still aid-related, the most recent development success stories, such as those in India and China, have a very different relation to aid—almost none at all.
