At the BBC we've had plenty of women in good management jobs. It comes and goes but there's been plenty. On air, I think there's quite a bit more we can do.

Even though disciplined sleeping habits and the adrenalin of live radio ensures that we are very awake while on duty, there is evidence of a phenomenon called circadian desynchronosis which causes one's brain to function slowly at those times of day when it thinks it should be asleep, regardless how wide awake the body is.

It doesn't annoy me but I think of myself as a presenter who is gay, rather than a gay presenter. It's a subtle distinction, but that's how I view it.

The new industries are brainy industries and so-called knowledge workers tend to like to be near other people who are the same. Think of the City of Hollywood. People cluster. This means you have winning regions, such as London and Cambridge, and losing regions. The people who want to be top lawyers in Sunderland are hoovered up by London.

Crossrail is a prime example of infrastructure. It is a rather deadly word, but I think it is exciting stuff, the civil engineering which makes Britain tick - the bridges, tunnels, power and water networks, which bind us together.

I actually profoundly think the world's a better place when economics is fairly boring... The more boring the better.

I don't particularly like going on about being gay or making a big thing about it, but I think it's a bit of a pain to be secretive about it.

Personally, I don't see old economics and behavioural economics as opposed. It is useful to assume people are rational as a good approximation to their long term behaviour, but it would be unwise not to think how in practice their behaviour may deviate from that simplifying assumption.
