Why Japan’s Forward Guidance Failed: The Shocking Truth About Central Bank Promises

Rethinking the Power of Forward Guidance: Lessons from Japan

Mark Gertler

In 2013, Japan’s central bank promised to keep rates low forever. The result? Almost no inflation. This video dives into the 'Forward Guidance Puzzle'—why traditional economic models predicted massive effects, but reality delivered almost nothing. We explore a groundbreaking study by economist Mark Gertler, which reveals that public expectations aren't rational; they're adaptive. People need to see inflation to believe it. This explains why Japan’s policies fell flat, and what it means for other economies like the US and Europe. Watch to understand why promises alone can't fix a deflationary trap, and what central banks must do instead. Key insights from the paper 'Rethinking the Power of Forward Guidance: Lessons from Japan' (2017).
