Re: Reengineering the Fed



Per

Very well put. I agree wholeheartedly with everything you say. I was just
trying to put forward the expectations theory as a sort of tautology for
equating holding period yields. The key problem, which you highlight, is
that, like all neoclassical theorems, it assumes perfect information.

In your view consols become like gold: The expected return is primarily the
expected capital gain or loss. I agree. But, unlike gold, there is also a
pecuniary income stream at the root of their valuation. If the market
believes short term rates will be raised in the future, long term bond
prices will fall, today. I don't have an answer here. Does anyone one the net???
