Similar Theories
For more details on this topic, see Austrian business cycle theory#Similar theories.Debt deflation is not the only economic theory that cites credit bubbles as a key factor in economic crises; the most noted other theory is Austrian business cycle theory, which posits that economic crises are caused by excess credit growth and the malinvestment (misallocation of resources) that results, with these being caused by central bank monetary policy and the fractional-reserve banking system.
The first difference between these may be stated as debt-deflation being a demand-side theory, which emphasizes the period after the peak – the end of a credit bubble and contraction of debt causing a fall in aggregate demand – while the Austrian theory is a supply-side theory, which emphasizes the period before the peak – the growth of debt during the growth phase causing malinvestment. The theories may thus be seen as complementary, addressing different aspects of the issue, and are so-considered by some economists.
In normative respects the theories are sharply different, with proponents of debt deflation generally arguing in the Keynesian, more precisely Post-Keynesian, tradition that government action can be beneficial, notably via debt forgiveness or engineering inflation (to reduce debt burden), or facilitating change in industries and investments, while Austrian economists generally argue that there is nothing to be done, the "malinvestments" needing to be "worked out of the system".
There have been other theories of economic crisis citing credit, discussed at the relevant section of Austrian business cycle theory.

Famous quotes containing the words similar and/or theories:
“Mistakes, scandals, and failures no longer signal catastrophe. The crucial thing is that they be made credible, and that the public be made aware of the efforts being expended in that direction. The “marketing” immunity of governments is similar to that of the major brands of washing powder.”
—Jean Baudrillard (b. 1929)
“The wise man regulates his conduct by the theories both of religion and science. But he regards these theories not as statements of ultimate fact but as art-forms.”
