There is a large economic literature on intellectual property rights. However, the issue seems far from settled on what even the optimal duration for patents are. Note that open source is even a step further than a 0 day patent duration. A strong case for your view would probably be found in Boldrin/Levine: http://levine.sscnet.ucla.edu/general/intellectual/...

The cuisine and fashion industries both largely exist without intellectual property protection other than trademarks (n.b., they can use copyright on certain aspects of their work but this is generally thought to give little protection) yet they seem to flourish. How is this possible? In fashion, it is thought that copying the work of other designers can be ...

Here are Aghion et al (2005) on their approach: "There is a large literature on measuring innovation intensity, with the ...

Apparently not. A 2015 article by the author uses his index to evaluate economic growth across country and time, stopping in 2005, same as the index in the original paper. And yet, many of the other variables are in principle available for more recent years. The first best here would be for you to contact the author. He might be in the process of updating ...

So suppose there is new technology $A$ that only 1 person has access to. If there are multiple firms with production technology $y=k^\alpha$ then obviously if that new technology was available to them at low/no cost, the overall productivity of society would increase (each firm has $y=Ak^\alpha$) The problem is that it is likely the case that $A$ requires ...

Background Since the marginal cost of distribution for a creative work such as a song is now essentially zero, the efficient thing to do would be to provide all songs to listeners at a price of zero (i.e. to allow piracy). However, this neglects the fact that producing creative works involves a fixed up-front cost (e.g. studio recording time, or simply the ...
