Financial Innovation, Banking and Monetary Aggregates reviews the impact of financial innovation on the measurement of money and presents the first collection of country studies appraising the usefulness of Divisia indices in deriving monetary aggregates. Monetary aggregates are traditionally formed by simply summing various monetary components such as cash and balances in savings and cheque accounts. The monetary usefulness, or 'moneyness', of these components differs and can change as a result of innovation in banking, monetary transmission and payment services. To gauge the importance of such distortions and the merits of alternative weighted monetary indices, particularly Divisia indices, this volume brings together authoritative empirical studies of countries including the US, the UK, Germany, France, Sweden, Italy and Japan. The authors conclude by showing how Divisia monetary indices act as a useful supplement to traditional monetary aggregates.
