Returns to Inventors
通过将美国专利数据与芬兰雇主-雇员数据匹配，估计了专利发明对个人收入的影响，发现发明家因专利授权获得3%的临时收入奖励，而高被引专利则带来三年后30%的长期溢价。
A key input to inventive activity is human capital. Hence it is important to understand the monetary incentives of inventors. We estimate the effect of patented inventions on individual earnings by linking data on U.S. patents and their inventors to Finnish employer-employee data. Returns are heterogeneous: Inventors get a temporary reward of 3% of annual earnings for a patent grant and for highly-cited patents a longer-lasting premium of 30% in earnings three years later. Similar medium-term premia accrue to inventors who initially hold the patent rights, although they forego earnings at the time of the grant.
