• All the alleged key causes of SOE [State-Owned Enterprise] inefficiency - the principal-agent problem, the free-rider problem and the soft budget constraint - are, while real, not unique to state-owned enterprises.

So, in these two areas, forms of ownership do matter, but the critical divide is not between state and private ownership - it is between concentrated and dispersed ownerships.
