What Parts of Globalization Matter for Catch-Up Growth?
指出经济学家过度关注商品和服务流动，而忽视了思想流动对追赶型增长的关键作用，并用中国采用美国民航规则降低事故率等案例说明思想流动的量化效应。
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.)
