Two of my friends have been debating the merits of the broken window theory, and I'm wondering what you guys would provide as a response to the Keynesian's last response. Please see their message exchange below. Thanks for your help!
- Austrian Nicely written article. But is economics really a lesson? If it was, then why have we made the same mistakes that past decades, past centuries, and even past civilizations made? Krugman's philosophy is wrong because it tries to patch a scab with a razor. You can't stop a fire by pouring more kerosene, just as you can't stop a depression by further increasing the money supply
Austrian Actually even simpler - Krugman's philosophy is wrong because it just doesn't make sense. How can someone say that breaking windows leads to economic growth? Sure, it might put an extra $100 into a glass repair man's pocket, but it also takes $100 out of a homeowner's. He/she would then have less money to buy clothes or movie tickets, so other retailers would be out of a sale. Broken windows is like a ponzi scheme...it helps some at the expense of others
Keynesian That's basic economic theory. That hundred goes into the pockets of many others and will help the economy with each transaction even with its diminishing amount with each transfer.- Keynesian 100 turns to 90 in the pocket of another, which then may turn to 70 in the pocket of another, which then in turn may turn to 30 in the pocket of another. Savings then add to AD.
- Austrian It's definitely mainstream economic theory today, but it wasn't 150 years ago. I don't like the money multiplier, because I don't think it takes into account what would have happened if the incident didn't occur. If that guy's window didn't break, he'd have $100 to spend on something else (say a hat). And that money would then circulate to Hat Salesman Bob, who would then have money to pay Movie Ticket Man, who would then have money to pay Lipstick Sam. The money continues to circulate just as it would have if the window broke, but to different people. You can't just assume that $100 would stay in a bank account unspent. But even if it did, it'd help to lower interest rates (at least that's how it would be in a free-market economy), which would then encourage it to be spent instead of saved.
Keynesian You're not taking into account the possiblity that the money will have conditions on it. If he has that extra 100 he could save it and it would be a long run effect instead of a mandatory spending on fixing the window which would produce a short run effect.
Keynesian If he has to spend the money, it will be a positive effect to the economy in the short run, nearly guarenteed. Otherwise that money could be a long run efect on the economy through saving
