Rogoff vs Stiglitz en el debate griego

Si alguien no leyó la carta que en el 2002 Rogoff (Director of Research, IMF) le envío a Stiglitz, leala porque no tiene desperdicio. Aparte del chimenterío, tiene algunos puntos que siempre es bueno traer al debate actual (i.e., la crisis griega):

Let's look at Stiglitzian prescriptions for helping a distressed emerging market debtor, the ideas you put forth as superior to existing practice. Governments typically come to the IMF for financial assistance when they are having trouble finding buyers for their debt and when the value of their money is falling. The Stiglitzian prescription is to raise the profile of fiscal deficits, that is, to issue more debt and to print more money. You seem to believe that if a distressed government issues more currency, its citizens will suddenly think it more valuable. You seem to believe that when investors are no longer willing to hold a government's debt, all that needs to be done is to increase the supply and it will sell like hot cakes. We at the IMF—no, make that we on the Planet Earth—have considerable experience suggesting otherwise. We earthlings have found that when a country in fiscal distress tries to escape by printing more money, inflation rises, often uncontrollably. Uncontrolled inflation strangles growth, hurting the entire populace but, especially the indigent. The laws of economics may be different in your part of the gamma quadrant, but around here we find that when an almost bankrupt government fails to credibly constrain the time profile of its fiscal deficits, things generally get worse instead of better.

Y más adelante remata con un párrafo que me resulta brillante:

We certainly believe in the lessons of Keynes, but in a modern, nuanced way. For example, the post-1975 macroeconomics literature—which you say we are tone deaf to—emphasizes the importance of budget constraints across time. It does no good to pile on IMF debt as a very short-run fix if it makes the not-so-distant future drastically worse. By the way, in blatant contradiction to your assertion, IMF programs frequently allow for deficits, indeed they did so in the Asia crisis. If its initial battlefield medicine was wrong, the IMF reacted, learning from its mistakes, quickly reversing course.

No, instead of Keynes, I would cloak your theories in the mantle of Arthur Laffer and other extreme expositors of 1980s Reagan-style supply-side economics. Laffer believed that if the government would only cut tax rates, people would work harder, and total government revenues would rise. The Stiglitz-Laffer theory of crisis management holds that countries need not worry about expanding deficits, as in so doing, they will increase their debt service capacity more than proportionately. George Bush, Sr. once labeled these ideas "voodoo economics." He was right. I will concede, Joe, that real-world policy economics is complicated, and just maybe further research will prove you have a point. But what really puzzles me is how you could be so sure that you are 100 percent right, so sure that you were willing to "blow the whistle" in the middle of the crisis, sniping at the paramedics as they tended the wounded.

El subrayado es mío. Como soy un tibio no voy a contar mi opinión al respecto. Simplemente me parece brillante la analogía con la curva de Laffer. Igual queda todo entre amigos...
