Interest and Prices

Wicksell's Interest and Prices is a landmark work in the history of economic thought. It is the first systematic exposition of the relationship between the money rate of interest and the natural rate, and it sets out the famous "cumulative process theory," laying a cornerstone for modern monetary policy theory. The book's value far exceeds the era of its publication: although its discussions date from the late nineteenth century, its core insights have endured across the centuries and still offer a key to understanding contemporary economic fluctuations. Wicksell observed acutely that when the money rate deviates from the natural rate, the price level undergoes cumulative movements, and this mechanism reveals the fundamental driving force of inflation and deflation. Unlike works that merely describe the quantity theory of money, this book brings capital, saving, and investment into a unified analytical framework and portrays the inner workings of the economic system dynamically. Readers should note that Wicksell's mode of argument still bears the deductive coloring of classical economics, but its theoretical core has been absorbed and developed by such major figures as Keynes and Lindahl, forming an important source of modern macroeconomics. The Commercial Press edition is meticulously translated and rigorously edited, with a detailed introduction; although some mathematical formulations seem slightly archaic, the sharpness of the thought is in no way diminished. For readers who wish to see through monetary phenomena to the nature of the economy, this is an irreplaceable intellectual ascent.
