In his book published in 2010, Joseph Stiglitz, a Nobel Prize-winning economist, arguesthat 'I believe that markets lie at the heart of every successful economy but that markets do not work well on their own...Government needs to play a role, and not just rescuing theeconomy when markets fail and in regulating markets to prevent the kinds offailures...Economies need a balance between the role of markets and the role of government...'
