Why the public sector?

A new report on the market for public services, commissioned from Oxford Economics by the CBI, demonstrates the growth of the public services industry in the UK. Government procurement of services in seven key sectors is now worth £44bn. Providers in this market generate £25bn in added value and employ over 700,000 people, making the industry bigger than the pharmaceutical and automotive industries combined. Surely such a big market is of interest for researchers. Surely, since it's public money that provides these services, media and stakeholders and politicians must demand transparency and accountability for the expenditure, so any research into how that money is spent on services must help improve transparency.
