This paper analyzes patent pools and their effects on innovation incentives. It is shown that the pro-competitive effects of patent pools for complementary patents naturally extend for dynamic innovation incentives. However, this simple conclusion may not hold if we entertain the possibility...

This paper develops a model of patent trolls to understand various litigation strategies employed by nonpracticing entities (NPE). We show that when a NPE faces multiple potential infringers who use related technologies, it can gain a credible threat to litigate even when it has no such...

We study the mapping between labor mobility and industrial innovative activity for thepopulation of R&D active Danish firms observed between 1999 and 2004. Our studydocuments a positive relationship between the number of workers who join a firm and thefirm’s innovative activity. This...

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces e.ort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a commitment...

We investigate the effect of mobility of R&D workers on the total patenting activity of their employers. Our study documents how mobile workers affect the patenting activity of the firm they join and the firm they leave. The effect of labor mobility is strongest if workers join from...
