The standard stream corresponding to Income No. 3 is constant in real terms... We ask... how much he would be receiving if he were getting a standard… - John Richard Hicks

The 'new theory of money and the cycle' which is spoken of in the opening paragraph is of course Hayek's. It was from Hayek that I began - where I got to will be seen. Even at the end, I was minimising my differences from Hayek. I could do so because, as I have elsewhere explained (Economic Perspectives, p. 141n), I still thought, like Pigou and Robertson, and Hayek, but by that time unlike Keynes, that 'we were talking about fluctuations, which, since they did not result in complete collapse or complete explosion, could not have engendered an expectation of going on forever. Booms could then be considered as times of high prices, slumps as times of low prices - with regard to some norm, which throughout the which throughout the fluctuations would not be changed, or not much changed'.

I can date my own personal 'revolution' rather exactly to May or June 1933. It was like this. It began... with Hayek. His "Prices and Production" is one of the influences that can be detected in The Theory of Wages; it could not have been otherwise, for 1931 was a Prices and Production year at the London School of Economics... I did not in fact find it all easy to fit in with my own ideas. What started me off in 1933 was an earlier work of Hayek's, his paper on 'Intertemporal Equilibrium', an idea which I found easier to reduce to my preferred (Paretian or Wicksellian) pattern.

While economic theory in general may be defined as the theory of how an economic condition or an economic development is determined within an institutional framework, the deals with how to judge whether one condition can be said to be better in some way than another and whether it is possible, by altering the institutional framework, to achieve a better condition than the present one.
