Monetary equilibrium requires i = r. Knut Wicksell 1851 – 1926
Wicksell’s interest rate rule for monetary equilibrium • So long as prices remain unaltered the (central) bank’s rate of interest is to remain unaltered. If prices rise, the rate of interest is to be raised; and if prices fall, the rate of interest is to be lowered; and the rate interest is henceforth to be maintained at its new level until a further movement of prices calls for a further change in one direction or another. Wicksell, Interest and Prices, p. 189 quoted in Michael Woodford, Interest and Prices: Foundations of a Theory of Monetary Policy, p. 38
The Stockholm School Gustav Cassel 1866 – 1945 Purchasing Power Parity General equilibrium … extension of Walras A writer less generous than Cassel would be hard to find. Marx at least paid tribute to Quesnay and Ricardo. Cassel paid tribute to nobody. Walras had written the first system of simultaneous equations of general equilibrium. Pareto had purged it of any measure ofsensations. Cassel followed both but mentioned neither… Eli Heckscher 1879 – 1952 Economic historian at University of Stockholm “Classical” theory of interest: rate that equates saving & investment Foil for Keynes in General Theory Ohlin-Hecksher Trade Theory (Factor Endowments) Teacher of Myrdal, Ohlin
