People today don't become economists to make the world a better place.

Bill Phillips was this nervous, chain-smoking student. He had signed up to be an engineer, he had gone away to fight in the Second World War, he had come back. He had switched to sociology because he wanted to understand how people could do these terrible things to each other. And he did a little bit of economics on the side.

Funnily enough, the Federal Reserve produced comics about monetary policy, and there is a good comic book guide to microeconomics and macroeconomics out there. But it is not really appropriate for younger readers; it is really aimed at economics students.

It's difficult because we tend to overrate the pain of failure. We fear it too much. That's research that emerges from psychology. We think it's going to be worse than it really is. And, I think, as we get a bit older, really after we leave school or college, we quickly stop experimenting.

I think having a back-up plan is never a bad thing. I would hate to be a male footballer and look back on 15 years of my career and think, 'Oh well, I've got a lot a money but what now?'

Negative interest rates hurt banks' balance sheets, with the 'wealth effect' on banks overwhelming the small increase in incentives to lend.

When you are in the biggest clubs, and you are fighting for the best players with a lot of money, maybe the work of a sporting director is not so difficult.

I used to buy nice clothes and drive a nice car when I couldn't afford it. But I spent all my money doing it, and now I don't have to. I like nice things. I like to travel in a certain style. I like to live in a nice place.
