Hi Bjørn,
I am currently writing my master thesis in competition law on network effects and computer software.
This looks like an interesting theme. I have a plan to work on a similar theme - market failure in the case of information goods, software and network effects.
I'm not a postgraduate student (yet) and I'm thinking on doing this on my on - just something to work on for the summer.
Anyway I'm at the beginning, so maybe we can share some ideas and information?
Cheers, Novica
