I show that it is always profitable for an incumbent subject to wholesale regulation to degrade wholesale quality in a non-recoverable fashion. The findings are robust to the number of competitors and the price cap level, unlike those predicted by...

Bandwidth allocation in peer-to-peer file sharing networks

We present a model of bandwidth allocation in a stylized peer-to-peer file sharing network. Given an arbitrary population of peers composed of sharers and freeriders, where all peers interconnect to maximize their allocated bandwidth, we derive the expected bandwidth obtained by sharers and freeriders. We show that sharers are always better off than freeriders and that the difference decreases ...

Only consumers who purchase the platform can access content from the prod...
