In the first of a two part series, Martin Wolf, the chief economics commentator of the Financial Times, examines how the world has changed since the beginning of the financial crisis four years ago and asks if the pre-2007 era might be the high point for free market capitalism.

Will the world face the combination of post-crisis austerity and disappointing global growth? Will fiscal pressure become a permanent feature of political, economic and social life in developed countries? Will there be a re balancing of East and West and will the on going crisis in the Euro zone lead to a greater or weaker currency union?

Martin Wolf talks to world leaders such as US Treasury Secretary Timothy Geithner, IMF Managing Director Christine Lagarde and Chairman of the UK Financial Services Authority Adair Turner to examine how the consequences of our economic choices have evolved since 2007 and what the future could look like in a world where there are no easy answers.
