A link to this blog from a US legal advisory website the Practising Law Institute’s In Brief ( “DEFLATION IN THE REAL WORLD“) reminded me of Bernanke’s book Essays on the Great Depression, which I’ve been aware of for some time but have yet to read. I’ll make amends on that front early this year; fortunately, an extract from Chapter One is available as a preview on the Princeton site (I couldn’t locate the promised eBook anywhere!; in what follows, when I quote Bernanke it is from the original journal paper published in 1995, rather than this chapter).
To put it mildly, Bernanke’s analysis is not promising.
The most glaring problem on first glance is that, despite Bernanke’s claim in Chapter One “THE MACROECONOMICS OF THE GREAT DEPRESSION: A Comparative Approach” that he will survey “our current understanding of the Great Depression”, there is only a brief, twisted reference to Irving Fisher’s Debt Deflation Theory of Great Depressions, and no discussion at all of Hyman Minsky’s contemporary Financial Instability Hypothesis.
While he does discuss Fisher’s theory, he provides only a parody of it–in which he nonetheless notes that Fisher’s policy advice was influential:
“Fisher envisioned a dynamic process in which falling asset and commodity prices created pressure on nominal debtors, forcing them into distress sales of assets, which in turn led to further price declines and financial difficulties. His diagnosis led him to urge President Roosevelt to subordinate exchange-rate considerations to the need for reflation, advice that (ultimately) FDR followed.
He then readily dismisses Fisher’s theory, for reasons that are very instructive:
Fisher’s idea was less influential in academic circles, though, because of the counterargument that debt-deflation represented no more than a redistribution from one group (debtors) to another (creditors). Absent implausibly large differences in marginal spending propensities among the groups, it was suggested, pure redistributions should have no significant macroeconomic effects. ” (Bernanke 1995, p. 17)
This is a perfect example of the old (and very apt!) joke that an economist is someone who, having heard that something works in practice, then ripostes “Ah! But does it work in theory?”.
It is also–I’m sorry, there’s just no other word for it–mind-numbingly stupid. A debt-deflation transfers income from debtors to creditors? From, um, people who default on their mortgages to the people who own the mortgage-backed securities, or the banks?
Well then, put your hands up, all those creditors who now feel substantially better off courtesy of our contemporary debt-deflation…
What??? No-one? But surely you can see that in theory…
