From the shopping mall to the corner bistro, knockoffs are everywhere in today's marketplace. Conventional wisdom holds that copying kills creativity, and that laws that protect against copies are essential to innovation--and economic success. But are copyrights and patents always necessary? In The Knockoff Economy, Kal Raustiala and I argue that creativity can not only survive in the face of copying, but can thrive. 

The Knockoff Economy approaches the question of incentives and innovation in a new way--by exploring creative fields where copying is generally legal, such as fashion, food, and even professional football. In our examination of creativity in these important but rarely studied industries, Kal and I find a nuanced and fascinating relationship between imitation and innovation. In some creative fields, copying is kept in check through informal industry norms enforced by private sanctions. In others, the freedom to copy actually promotes creativity. High fashion gave rise to the very term "knockoff," yet the freedom to imitate great designs only makes the fashion cycle run faster--and forces the fashion industry to be even more creative.
