Yet another economic treatise by an Austrian. This time Ludwig von Mises. A powerhouse of classical liberalism. In this book, Mises traces the origin of money to its roots in market exchanges, where its value emerges from its usefulness as a commodity in trade. Through this analysis, he builds a compelling case for “sound” money—money that maintains its value and resists inflationary pressures. Mises opposes the use of monetary policy to manipulate economic outcomes (e.g., growth and unemployment), arguing that money should function as a neutral medium of exchange (dictated by market participants), rather than a tool for economic engineering. To support this neutrality, he advocates for the use of the gold standard (whereby currency is defined by a stated quantity of gold), viewing it as essential for preserving the stability and integrity of money within the economy. In contrast, fiat money, which can be created at the discretion of the state, expands government power and undermines economic freedom.
One of the most groundbreaking aspects of this treatise is Mises’ application of marginal utility analysis to money demand. By doing so, Mises offers an explanation of the purchasing power of money and its fluctuations. This approach was revolutionary, as it expanded upon the mainstream Quantity Theory of Money (QTM), which hypothesizes that prices are directly proportional to money supply. Although Mises acknowledges this insight, he critiques QTM for being overly simplistic in the mechanistic way through which changes in money supply affect prices. According to Mises, these changes are deeply influenced by the subjective evaluation of market participants regarding the usefulness or value of money. This value, Mises argues, can be traced back through time, leading to his most intriguing contribution—the “regression theorem.” This theorem posits that the purchasing power of money today is linked to its value yesterday, thereby creating a continuous regression to the initial point when money was first introduced.
Cool stuff all around.
