Stability of money demand in Switzerland: A comparison of the M2 and M3 cases

Long-run parameters of money demand functions for Switzerland's M2 and M3 aggregate are estimated and their stability investigated. For both aggregates a single stable cointegrating vector is found. Around these long-run relationships a single-equation model for m2 and a single-equation model for cpi is built respectively for M2 and M3, and both estimated models are found to be stable. Testing forecast performance, the cpi model seems to be superior to the m2 model, providing some positive signs that the M3 model is stable in the sense that it does not suffer from a structural break during the period of estimation.
