More on Negative Interest Rates

From Glenn Rudebusch of the San Francisco Fed:

The recommended future policy setting of the funds rate based on the estimated historical policy rule and these economic forecasts is given as the dashed line in Figure 2. This dashed line shows that, in order to deliver a degree of future monetary stimulus that is consistent with its past behavior, the FOMC would have to reduce the funds rate to -5% by the end of this year—well below its lower bound of zero.
