Leverhulme Centre for Market and Public Organisation
This organization is based at the University of Bristol. Its major
focus is on the "interface" between private and public organizations;
for example, how can public entities be organized to confront the
correct set of incentives. They have a large literature review on this
area, as well as their own research. They also provide information on
pensions.
