Prices and industrial transformation

Abstract

One of the contradictions of neo-classical economic theory concerns its view of relative prices. On the one hand it is relative prices that determine the market's equilibrium position and decide what transactions will take place. On the other hand, the pattern of relative prices, or expressed differently the price structure, has been regarded as more or less immutable. Variations in relative prices have been considered short-term phenomena, after which, in time, an adaptation has taken place which has restored the initial situation. The same line of thought was also held by Wesley Mitchell, who in the dispersion of relative prices found a reflection of business cycles, but he maintained that the price system is “yet stable in the essential balance of its interrelations”.¹ F.C. Mills cited Mitchell as his authority in his comprehensive work The Behavior of Prices, and although he felt compelled to raise objections to the inference that relative prices varied rhythmically with the business cycle, he still considered that there was a limit to change in relative prices, i.e. the price structure had a fundamental stability.²
