"There can, of course, be little doubt that, at the present time, a deflationary process is going on and that an indefinite continuation of that deflation would do inestimable harm. But this does not, by any means, necessarily mean that the deflation is the original cause of our difficulties or that we could overcome these difficulties by compensating for the deflationary tendencies, at present operative in our economic system, by forcing more money into circulation. There is no reason to assume that the crisis was started by a deliberate deflationary action on the part of the monetary authorities, or that the deflation itself is anything but a secondary phenomenon, a process induced by the maladjustments of industry left over from the boom. If, however, the deflation is not a cause but an effect of the unprofitableness of industry, then it is surely vain to hope that, by reversing the deflationary process, we can regain lasting prosperity."
Friedrich Hayek, Monetary Theory and the Trade Cycle (1933)
