Has the Welfare State Had Its Day?

We look at the future of the welfare state with one of the world's leading thinkers on welfare economics, Nobel prize winner Professor Amartya Sen. Also, we speak to the head of legal at Finland's benefits agency, Marjukka Turunenask, which is experimenting with a universal basic income. Could basic incomes for the unemployed replace traditional benefits payments? And the BBC's Joe Miller reports from the World Economic Forum in Davos, Switzerland, where climate change scientists are meeting with business and economic leaders.
