“…However, whether property rights actually incentivize innovation is hotly debated. For instance, there is evidence from historical policy changes that property rights incentivize innovation (MacGarvie & Moser, 2015;Moser, 2005Moser, , 2013, but there is also evidence that these effects are somewhat more modest than the theoretical characterization of property rights (Lerner, 2009;Sakakibara & Branstetter, 2001).
