Perhaps Bob’s sushi example could have started even before the ‘boom’ in the sectors closer to sushi eating. Say, a boom in motorboat making that would have brought about ‘forced saving,’ that is, a depletion of sushi. Bob might have realized that the analogy kind of dies when trying to come up with a parallel for the initial expansion of credit which bids the prices of investment goods and lengthens the structure of production.
Either way, his main focus is in trashing Krugman, whose proposal is to boost consumption, so it is more fitting that Bob’s story begins during a later phase of the boom, where it is already goods closer to consumption that are thriving, and pressure is already building to sustain such consumption even without the requisite higher-order stages.
For purposes of making his point, Bob speaks of sushis increasing in comparison to before Krugman’s intervention. But as far as I know, the Austrian theory does not suppose an increase of goods, whether first-order, higher-order, or aggregate. What Hayek focuses on is the ratio between resources for investment and those for consumption.
So if the original pre-Krugman I:C ratio was 4:2, the Krugman intervention would shift this to 2:4. Even if sushis don’t increase in number, the resources devoted immediately to them are more than that for motorboats and stuff. Obviously, the investment resources are not enough to sustain sushi, and eventually consumption would be reduced to 25% of the ‘consumption boom’ period, that is, the ratio will go back to 2:1 (which is equal to 4:2).
I don’t know if this helps your contemplation of the matter, but I do realize now that Bob’s article is definitely wanting if you’re looking for a complete explanation, particularly due to the absence of a central bank parallel. But thank goodness we have Hayek and De Soto to provide their expositions.
Jonathan, hi I’m Francis B.'s friend from the Philippines. I read your article, and it’s always enjoyable to read about ‘modern’ ways of understanding ABCT. It goes to show that reading theory from the greats is not enough; the ability to interpret situation to situation is just as important to gain understanding of phenomena.
I myself am inclined to see the housing bubble as an investment boom. But the beauty of ABCT is that you can derive understanding of the crisis whether you consider houses as capital goods or as consumer goods. They were capital goods in the sense that the mortgages financed the large financial institutions and thus stimulated investment; also because the houses were often held on to in the hopes of greater returns in the future.
They were consumer goods in the sense that people borrowed on their houses in order to finance their consumer goods’ expenses, and also because people actually lived in the places they bought.
Goes to show how a good analysis may be flexible with regards to treatment of the variables considered (e.g. whether houses are consumer or capital goods), but nonetheless logical in the exposition (e.g. the boom depletes resources nonetheless).
