Money Growth Volatility and the Demand for Money in Germany
Friedman’s Volatility Hypothesis Revisited
Recently, the Bundesbank claimed that monetary targeting has become considerably more diffcult by the increased volatility of short-term money growth. The present paper investigates the impact of German money growth volatility on income velocity and money demand in view of Friedman’s money growth volatility hypothesis. Granger-causality tests provide some evidence for a velocity-volatility linkage. However the estimation of volatility-augmented money demand functions reveals that - in contrast to Friedman’s hypothesis - increased money growth volatility lowered the demand for money.
