From deep within the bowels of the way-back machine,
Krudman writes for Slate back in 1998:
A few weeks ago, a journalist devoted a substantial part of a profile of yours truly to my failure to pay due attention to the “Austrian theory” of the business cycle—a theory that I regard as being about as worthy of serious study as the phlogiston theory of fire. Oh well. But the incident set me thinking—not so much about that particular theory as about the general worldview behind it. Call it the overinvestment theory of recessions, or “liquidationism,” or just call it the “hangover theory.” It is the idea that slumps are the price we pay for booms, that the suffering the economy experiences during a recession is a necessary punishment for the excesses of the previous expansion.
The hangover theory is perversely seductive—not because it offers an easy way out, but because it doesn’t. It turns the wiggles on our charts into a morality play, a tale of hubris and downfall. And it offers adherents the special pleasure of dispensing painful advice with a clear conscience, secure in the belief that they are not heartless but merely practicing tough love.
Powerful as these seductions may be, they must be resisted—for the hangover theory is disastrously wrongheaded. Recessions are not necessary consequences of booms. They can and should be fought, not with austerity but with liberality—with policies that encourage people to spend more, not less. Nor is this merely an academic argument: The hangover theory can do real harm.
We must prevent people from saving their money at all costs. If people were to save, the economy would implode! This is just silly when we have printing presses. If we simply print the money, investors can have money to expand future production and people can spend money at the same time! It makes perfect sense.
