Answer:
0.95%
Explanation:
Taylor's rule formula is as follow:
Target rate = Neutral rate + 0.5 x (Expected GDP growth rate - Long-term GDP growth rate) + 0.5 x (Expected Inflation rate - Target inflation rate)
The neutral rate is not given in the question. So let's assume that neutral rate is = 3%
--> Target rate = 3% + 0.5 x (-4%) + 0.5 x (2% - 2.1%)
--> Target rate = 1% - 0.05% = 0.95%
