Financial innovation and demand for money: some empirical evidence

Recent criticism of money growth targets has been based on the implications of spreading financial innovation, since the latter has been considered to undermine monetary policy effectiveness both by bringing about an increase in the interest elasticity of money demand and by producing instability of the money demand function. The empirical results presented in this paper - focusing on a single and specific case of financial innovation particularly suited to study the isssue at stake - falsify both hypotheses.
