Context: <response>: Hayek main research for economics dey focus on capital, money, and the business cycle. Mises bin don apply di concept of marginal utility to di value of money for im Theory of Money and Credit (1912), where e also propose explanation for "industrial fluctuations" based on di ideas of di old British Currency School and Swedish economist Knut Wicksell. Hayek use dis work as starting point for im own interpretation of the business cycle, wey later become known as di "Austrian Theory of the Business Cycle". Hayek explain di Austrian approach for im book wey e publish for 1929, wey later translate to English for 1933 as Monetary Theory and the Trade Cycle.

Hayek talk say "the past instability of the market economy na because money, wey be di most important regulator of the market mechanism, no dey regulated by the market process".
