The Return of the Prince of Denmark: A Survey on Recent Developments in the Economics of Innovation
综述了创新经济学中三个新兴领域：知识溢出对生产率的影响、研发合作的不同形式以及累积创新中专利的作用，总结了当前文献的进展和未来发展方向。
It is well known that innovation is the engine that drives the growth machine of modern capitalist economies. Therefore, not surprisingly, substantial attention has been devoted by economists to the process behind the production of innovations. Three areas have recently emerged as relevant in the field. These are: the impact of spillovers on productivity; the different forms of R&D cooperation and the role of patents in fostering innovations when these are cumulative. In this paper I summarise the relevant literature in these three areas by discussing where the current literature stands and what are its future developments.
