What are anchored inflationary expectations and how do they reduce the cost of an adverse inflation shock?
Well-anchored inflation expectations imply a muted response of inflation to a highly-negative output gap. However, a long-lasting negative gap episode gradually induces a moderate but persistent decline in long-runinflation expectations. As a result, inflationpersistently undershoots the Fed's target inflation
A drop in inflationary expectations results in a rightward shift in AS, thus lowering inflation for any given unemployment level and shifting the Phillips curve to the left.
