By 2050 the big economies will no longer be emerging, and the emerging economies will no longer be very big

It was an eventful and exciting week at the World Economic Forum’s Annual Meeting at Davos last month, which was started with the backdrop of the ongoing Eurozone crisis that the region was battling with.

It was eventful because the annual meeting, as every year, provided business leaders with the ideal platform to get together to discuss and debate on key issues that the world was facing with today. It was exciting because despite the vast diversity of events and business leaders that participated in them, what emerged was a common focus - the need for businesses and business leaders to adapt to the emerging future that we are faced with.

Proposals for a tax on financial transactions, which caused UK Prime Minister David Cameron to refuse to vote for proposed changes to the European Union treaty to create a closer fiscal compact for the euro zone, will become reality, Wolfgang Schaueble, Germany’s finance minister, told CNBC at the World Economic Forum in Davos Friday.

Once again, the World Economic Forum's lineup of keynote speakers was extremely impressive. Let's be frank, what other forum in the world—especially in such an inconvenient and remote location—actually manages to attract not just German Chancellor Angela Merkel and UK Prime Minister David Cameron, but also policy heavyweights Mario Draghi from the European Central Bank and Timothy Geithner from the US Treasury Department in the space of only three days? Well, very few.

But browsing through the session and attendees lists, I couldn't shake off the thought that some of the key people are actually missing this year. No, I'm not talking Bono and Angelina Jolie.

A deal with private investors to swap Greece's debt to a more manageable burden is close to being concluded and the next three days are crucial, Olli Rehn , the European Union's monetary affairs commissioner, said during a debate hosted by CNBC in Davos.
