Nobel Lecture: The Process and Progress of Economics
探讨新思想在经济学中被接受或拒绝的原因，区分学科的前科学和科学阶段，并用信息经济学和规制理论等历史案例说明不同思想的命运。
The lecture focuses on the reasons that new ideas are accepted or rejected by a science. A distinction is drawn between prescientific and scientific stages of a discipline. The diverse fates of new ideas are illustrated by a variety of episodes in the history of economics, including the economics of information and the theory of economic regulation.
