My interest in economics has always been in the whole corpus of economic theory, the interrelationships between the various fields of theory and their relevance for the formulation of economic policy.

Good environmental policy is good economic policy.

My job was to teach the whole corpus of economic theory, but there were two subjects in which I was especially interested, namely, the economics of mass unemployment and international economics.

I have learned as much in the last three years as in any other comparable period of my life, but with an added realisation of how little over a half century of study one has in fact managed to learn of the whole range of economic policy issues.

Economists agree about economics - and that's a science - and they disagree about economic policy because that's a value judgment... I've had profound disagreements on policy with the famous Milton Friedman. But, on economics, we agree.

The successful conduct of economic policy is possible only if there is - and is seen to be - full agreement between the Prime Minister and the Chancellor of the Exchequer.
