THEORIES OF ENTREPRENEURSHIP, INNOVATION AND THE BUSINESS CYCLE
梳理了将企业家及其创新与商业周期产生和规模联系起来的几种主要经济理论，包括创造性破坏模型、创新与实施周期模型以及信息不对称下的生产模型，并提炼了关键见解、政策含义和未来研究方向。
Abstract This paper discusses several prominent economic theories which link entrepreneurs and their innovations to the creation and magnitude of business cycles. I distinguish three broad classes of theories: models of creative destruction; models of innovation and implementation cycles; and models of production under asymmetric information. Key insights of the theories are identified, policy implications are drawn, and suggestions for future research are proposed.
