For the last three years, there has been no breakfast for journalists on the opening day of Jackson Hole, while we write up a dramatic, market-moving speech by Ben Bernanke. It’s a more sedate start this year with a thoroughly wonkish paper by Stanford’s Robert Hall.
There is not much new in it on policy. It starts with a fairly straightforward rundown on why the economy got into such a mess when interest rates hit zero after the financial crisis, and it ends by agreeing with last year’s paper by Michael Woodford on what to do with monetary policy (QE doesn’t work, you need commitments about future policy, not just guidance).
The meat of Mr Hall’s paper is about why inflation did not fall much after the crisis despite high levels of unemployment. This has been a surprise during the last few years: unemployment has not driven down wages in a way that led to deflation.
