European reforms 

Is being in Europe going to improve GDP for UK? It's difficult to know, economists struggle to forecast next quarters GDP growth in slightly unforeseen territory let alone long term trends for such an unpredictable event.

Being in Europe working together can help us against certain game theory tactics that can be resolved on a European level. More unified policies for business across Europe can encourage more companies from around the world to enter one common market with simple rules across it and over 500 million middle class citizens, rather than many different markets to understand.

Working in numbers can also be easier for trade deals and comes with many other benefits. But this has to be met by less bureaucracy what many European leaders also want.

Some simple ways countries can try and improve Europe

• More unified qualification system across Europe so different qualifications are more widely know 
• Complete single market reforms on telecommunications, transport, energy
• Give OFT and similar bodies more money to do more analysis on how to improve different markets across Europe
• Unify business bureaucracy across Europe so company can expand and move easier

There are many more reforms individual countries can take and more complex policies Europe can take what I will leave for another post.
