Arnold Kling explores whether Keynes would have supported the stimulus bill. An excerpt:
Another group of skeptics is concerned about the timing of the fiscal stimulus. Even some economists on the left, including Alice Rivlin and Jeffrey Sachs, have made the point that the long-term spending in the stimulus bill is inappropriate and even counterproductive from a stimulus perspective. I share this concern. President Obama said that his goal is to have 75 percent of the stimulus take effect before the end of 2010. Instead, I would argue that we should have 100 percent take effect by then, and 75 percent take effect by the end of 2009.
