Transmission Mechanisms of QEP
New Monetary Policy Framework
(1) Interest Rate Effect (2) Expectation Effect - Commitment Effect - Time-lag Effect - Signaling Effect (3) Portfolio Rebalancing Effect - Induced by Increase in CAB Target - Induced by Increase in BOJ’s JGB purchase
Attainable by Zero Interest Rate Policy as well

Summary of Examination on QEP
I. Macroeconomic Effect……………….……………. Effective
II. Transmission Mechanisms (1) Interest Rate Effect……………………………. Not Unique to QEP (2) Expectation Effect - Commitment Effect…………………………… Effective, but not Unique to QEP - Time-lag/Signaling Effect…………………….. No Effect Found (3) Portfolio Rebalancing Effect - Induced by Increase in CAB Target…………... No Effect Found - Induced by Increase in BOJ’s JGB purchase…. No Certain Results
