Allan Meltzer and John Taylor organized a Statement on Policy Rules Legislation signed by quite a few famous economists. John's blog explains in some detail.
Stating a rule or "strategy" about what things the Fed will react to also will help the Fed to pre-commit to things it will not react to. If the Fed says they react to inflation and unemployment, that means you should not expect it to react to stock prices, oil prices, exchange rates, and so forth.
Ms. Yellen's testimony and monetary policy report happen Feb 10 and 11. It will be interesting to hear the discussion of these issues. I hope that discussion includes not just legislation, but whether the Fed should follow something like this strategy communication on its own, in order to limit pressures for the Fed to do unwise things.
