The case for more stimulus

MBA 505 students are just starting the module on macroeconomics.  In the interest of balancing the link to Jeff Miron's article criticizing the stimulus packages, I am linking to a recent Paul Krugman column where he argues that the stimulus packages did not go far enough and much more stimulus is needed.  My students might want to start thinking about why two top notch economists can come down so differently on this issue.
