An experiment on protecting intellectual property
通过实验室实验，研究知识产权保护是否激励人们创造非竞争性知识产品，发现知识产权保护本身并非创造财富的必要或充分条件，个人创业才是关键。
Abstract We conduct a laboratory experiment to explore whether the protection of intellectual property (IP) incentivizes people to create non-rivalrous knowledge goods, foregoing the production of other rivalrous goods. In the contrasting treatment with no IP protection, participants are free to resell and remake non-rivalrous knowledge goods originally created by others. We find that creators reap substantial profits when IP is protected and that rampant pirating is common when there is no IP protection, but IP protection in and of itself is neither necessary nor sufficient for generating wealth from the discovery of knowledge goods. Rather, individual entrepreneurship is the key.
