The wildly-popular pop psychology book written by John Gray in the 90s claimed that Men are from Mars, Women are from Venus.

Princeton professors Markus K. Brunnermeier, Harold James and Jean-Pierre Landau claim that the heavyweights of Europe similarly have clashing views, backgrounds and ideas.

Their divergent viewpoints come from completely different histories, cultures and experiences with dealing with their economies.

So it is inevitable that this clash is rocking the eurozone - and could have and impact on Brexit too, according to the professors.

Some of these divergences have never been addressed or considered, even though they have an enormous impact on what each bring to the table in times of crisis or with dealings with other countries.

In this episode of the Big Money Questions Markus and Harold explain the key differences between the countries and what they could mean for the future of the euro - and for Britain's relationship with Europe.
