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.

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.

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.

Interestingly, human irrationality is a hot topic in economics at the moment. Behavioural economics it's called, on the cusp of economics and psychology.

Once we are fed, heated, housed and healthy, our extra consumption inevitably has an element of luxury about it. And once luxury enters the scene, the practicalities are in trouble, as women who wear expensive stiletto heels can testify.

For me, the main principle for broadcasters has to be that if people stand to benefit from an interview, they should be prepared to face some downside as well.

It is no wonder that bank capital is regulated. When borrowing and lending is profitable, it is tempting for banks to scale up their operations and to borrow and lend too much in relation to their capital, in effect reducing the effectiveness of the potential capital cushion.
