Sept 5: Becker defends Chicago school

The "Chicago school" of free market-centric economics, highly influential in forming laisser faire policies, has faced fierce criticism in the wake of the financial crisis. Gary Becker, University of Chicago professor and Nobel laureate for economics, tells Martin Wolf why the crisis has done little to change his view that markets work well - and governments "usually mess things up".
