I wonder if economics has less basic core material than is necessary for fields such as mathematics, physics, or chemistry, say.

A teacher told my mother that I would never become successful, which illustrates the difficulty of long-run forecasting on inadequate data.

Rob Engle and I are concerned with extracting useful implications from economic data, and so the properties of the data are of particular importance.

A potentially useful property of forecasts based on cointegration is that when extended some way ahead, the forecasts of the two series will form a constant ratio, as is expected by some asymptotic economic theory.

Inside of me, it was like my soul and what I had to do to feed my family was always split. I was writing lyrics while I was supposed to be working. I'd look up, and there's my supervisor.

I put on 'Starstruck' for my kids, and they started getting bored. I was so upset, I took it off. They preferred 'Home Alone.'

The fans sing my name around the world. When I meet fans, they ask, 'How are you? All good with your family?'

Music was your real passion, this thing you held dear even above family. It was this relationship that never betrayed you. Once it became your job - this thing that was highly visible, this thing that became about commerce - that's when you were holding onto music like it was a palm tree in a hurricane.
