Productivity
A way at creating a more productive public and private sector is by analyzing other countries successful political frame work for different sectors.
More money to the OFT to investigate why different sectors in other countries are more productive than us (plugging a skills gap, allowing more competition) while understanding our unique circumstances (Drop in public spending, historical differences) Can give politicians a better understanding of what to combat to increase productivity. 
This is also true for the public sector looking at why countries maybe spending less and getting better results (tax heaven, live in more highly dense cities, public have healthier lives) and can either give us direct policies to copy and see their success or try our own policies to combat these issues.
