A Krugman Puzzler

A Krugman Puzzler

I oftentimes disagree alongside Paul Krugman, precisely I commonly empathize him.  Lately, however, I receive got been puzzled close his regard of the bond market.  In a recent post, he takes President Obama to chore for believing that the failure to bargain alongside our long-term financial imbalance mightiness drive a spike inwards involvement rates:
America can’t run out of cash (except politically, if Congress refuses to heighten the debt ceiling); it basically can’t sense an involvement charge per unit of measurement spike unless people encounter an increased jeopardy of economical recovery as well as so a ascent inwards short-term rates. And the people who receive got been predicting an involvement charge per unit of measurement spike whatever solar daytime straightaway for iv years shouldn’t receive got whatever credibility at this point.

But dorsum inwards 2003, when the financial imbalance was much smaller, he wrote:
With nation of war looming, it's fourth dimension to endure prepared. So final calendar week I switched to a fixed-rate mortgage. It agency higher monthly payments, precisely I'm terrified close what volition tumble out to involvement rates in 1 lawsuit financial markets wake upward to the implications of skyrocketing budget deficits.... 
How volition the develop wreck play itself out? Maybe a hereafter management volition run butterfly ballots to disenfranchise retirees, making it possible to slash Social Security as well as Medicare. Or perchance a repentant Rush Limbaugh volition Pb the drive to heighten taxes on the rich. But my prediction is that politicians volition eventually endure tempted to resolve the crisis the way irresponsible governments commonly do: yesteryear printing money, both to pay electrical flow bills as well as to inflate away debt. 
And equally that temptation becomes obvious, involvement rates volition soar. It won't tumble out correct away. With the economic scheme stalling as well as the stock marketplace plunging, short-term rates are in all likelihood headed down, non up, inwards the side yesteryear side few months, as well as mortgage rates may non receive got striking bottom yet. But unless nosotros slide into Japanese-style deflation, at that spot are much higher involvement rates inwards our future. 
I recollect that the principal matter keeping long-term involvement rates depression correct straightaway is cognitive dissonance. Even though the delineate of piece of job concern community is starting to larn scared -- the ultra-establishment Committee for Economic Development straightaway warns that ''a financial crisis threatens our hereafter measure of living'' -- investors soundless can't believe that the leaders of the U.S.A. are acting similar the rulers of a banana republic. But I've done the math, as well as reached my ain conclusions -- as well as I've locked inwards my rate.
I am having problem reconciling these points of views.  Has Paul changed his mind since 2003 close how the bond marketplace works?  Or are circumstances unlike now?  If anything, I would receive got idea that the financial province of affairs is to a greater extent than dire straightaway as well as and so the logic from 2003 would apply alongside to a greater extent than force.  I am puzzled.

Update: Several people receive got emailed me possible resolutions of the puzzle, precisely none is actually satisfying.

One grouping of emailers says that things are unlike straightaway because nosotros are inwards a liquidity trap.  But dorsum inwards 2003 the federal funds charge per unit of measurement was at close 1 percent, as well as so nosotros were very to a greater extent than or less the zero lower bound.

Another grouping of emailers says that Paul has admitted that his 2003 forecast was mistaken.  But that is non the issue.  Of course, nosotros tin await dorsum and say it was mistaken.  No large deal.  Any economist who has always made a forecast has made some false forecasts.  The puzzle to me is how Paul tin human activity as well as so certainly that the outcome he viewed equally probable inwards 2003 is straightaway beyond the realm of the plausible, fifty-fifty though the financial imbalances are much larger.

By the way, my column coming out in Sunday's NY Times touches on these issues, which is why the puzzle came to mind.
