Bill Easterly supported the fiscal conservative call of Jeffrey Sachs, saying that in the time of crisis economists go back to basics.
I have to think it through. But, it seems to me that in the current situation two of the most sacred principles of economists depend on international economic coordination. Free trade, which is one of the principles, could diminish the impact of massive fiscal stimulus. So, government might call for "Buy National", otherwise, the stimulus should be bigger impairing fiscal sustainability, another sacred principle. What is required is simultaneous and coordinated international fiscal expansion, which ensures both free trade and long-term fiscal sustainability. This should be the G20 agenda, and that is what should be discussed both in Davos and Belem right now.
