I think that since Krugman believes that destruction stimulates the economy, he decided to blow up some cars for the good of America.
Aujourd'hui, ce qu'on ne voit pas est ce qu'on n'est pas. Capiche? Bastiat's parable about the broken window is only applicable if Say's Law isn't being tortured. The problem is that Say's Law frequently breaks down. An excess demand for money will cause a general glut of all other things, a recession. Even Say realized this years after he originally formulated his famous theory, recognizing that the Panic of 1825 had proven him wrong. He admitted as much to Malthus.
Bastiat makes the case that the shopowner "had [he] not had a window to replace... [would] have replaced his old shoes or added another book to his library. In short, he would have employed his six francs in some way..." but this fails to be true when Say's Law is being tortured such that there is an excess demand for money and a general glut throughout the rest of the economy. If the shopowner would have hoarded his six francs, the broken window does in fact create real and valuable economic activity that would not have otherwise existed. The glazier's work perhaps not for reasons that Bastiat illustrated (that which is unseen), but the six francs are put into circulation and the Keynesian multiplier can provide a net benefit.
Broken windows are the worst possible way to create that Keynesian effect, but many economists have utilized them as examples to highlight the Keynesian multiplier. Both Krugman and Keynes himself have made this sort of argument. When we talk about serious Keynesian proposals (say building a bridge or sending a child to school) that point often gets lost. People see the value of the investment and they often don't notice the multiplier right next to it, even though creating the multiplier is the primary objective of the proposal. When Keynes jokes about something as useless as burying money at the bottom of mine shafts and then leasing the land to savvy entrepreneurs, he does so to eliminate any perceived investment which makes the multiplier more noticeable. Neither Keynes nor Krugman want to break windows, but it's an effective example they use to highlight the Keynesian effect. Krugman is able to torture Bastiat's parable because Say's Law is being tortured in the real world.
However, I actually believe Krugman is a really nice person. I just think he's wrong on everything about the economy. And it's not that it is he specifically that's wrong, but it is the economic school of thought that he believes in (Keynesianism). He didn't predict the economic collapse, he didn't see the housing bubble, during the midst of it, as a bad thing. Again, it's not really him, but its Keynesian Economics that is wrong. However, I digress...
Umm, that's so wrong I don't know how exactly to respond.
Ton80 quoted a blog post written by econ professor Mark Perry (University of Michigan) in early 2008. Perry concluded that "
In other words, to paraphrase Megan McArdle, Paul Krugman has predicted nine out of the last none recessions". Perry made fun of Paul Krugman's worries abotu the housing bubble and the impact it's crash could have on the economy. Perry and McArdle both ate crow after subsequent events in 2008 made them look like fools. The NBER eventually dated the start of the recession back to late 2007.
Though Ton80 doesn't make this point, it's a great example of just how wrong you are. We have a reasonably well-known conservative economist (got a spot at the AEI) who is making fun of Krugman for his concerns about the housing bubble. Very few economists called the housing bubble and Krugman was probably the most prominent of the handful that did. Before the crash of 2008 proved him right, Krugman took a tremendous amount of flack for staking out that position. But he was right.
