Book excerpt: This book elaborates upon the dynamic changes to Korean firms and the economy from the perspective of catch-up theory. The central premise of the book is that a latecomer’s sustained catch-up is not possible by simply following the path of the forerunners but by creating a new path or ‘leapfrogging’. In this sense, the idea of catch-up distinguishes itself from traditional views that focus on the role of the market or the state in development.
