We document a series of new facts about the very first firms and patents that form new edges in the directed citation networks across patent categories. We call them pathfinder firms and patents. First, the typical pathfinder firms are very larger firms. Second, the average pathfinder patents...

This paper provides formal treatment to the idea of patenting as a form of market stealing between R&D firms. It extends the creative destruction literature by allowing innovations to build off each other forming a network of ideas. Patent citations keep track of this network. The theory maps...

The distribution of citations received by scientific publications can be approximated by a power law, a finding that has been explained by “cumulative advantage”. This paper argues that socially embedded learning is a plausible mechanism behind this cumulative advantage. A model assuming...
