Perhaps America's first celebrated economist, Irving Fisher-for whom the Fisher equation, the Fisher hypothesis, and the Fisher separation theorem are named-staked an early claim to fame with his revival, in this 1912 book, of the "quantity theory of money." An important work of 20th-century economics, this work explores: · the circulation of money against goods · the various circulating media · the mystery of circulating credit · how a rise in prices generates a further rise · influence of foreign trade on the quantity of money · the problem of monetary reform · and much more. American economist IRVING FISHER (1867-1947) was professor of political economy at Yale University. Among his many books are Mathematical Investigations in the Theory of Value and Prices (1892), The Rate of Interest (1907), Why Is the Dollar Shrinking? A Study in the High Cost of Living (1914), and Booms and Depressions (1932).
