Economics spreads happiness.

If the whole process of learning from failure means discarding stuff that's not working, but in fact, our natural reaction is to keep going, to throw more money behind it, to throw more emotional energy behind it... that's a real problem.

Norway has a relationship with the EU which is very close. It has to accept most EU rules. It has to pay EU membership fees. It has free movement of people just like other EU countries, but it's not actually in the EU.

Pluralism matters because life is not worth living without new experiences - new people, new places, new challenges. But discipline matters too; we cannot simply treat life as a psychedelic trip through a series of novel sensations.

We now have political chaos. We've got parties in Ireland saying they want to merge with Northern Ireland. You've got parties in Scotland saying you want to leave the U.K. You've got the Spanish government saying it would like to take ownership of Gibraltar, which is a British overseas territory... So just the politics of this is a mess.

Economics spreads happiness.

I see the God complex around me all the time in my fellow economists. I see it in our business leaders. I see it in the politicians we vote for - people who, in the face of an incredibly complicated world, are nevertheless absolutely convinced that they understand the way that the world works.
