It was to preserve and to extend the gains associated with low and declining inflation--and to avoid the instabilities and imbalances attendant to rising inflation--that we began the process of tightening one year ago.
The model is based on the observation that the instabilities occur with wavelengths much longer than the jet radius, so that the jet can be modeled as a long, slender object.
