What analysis has been done to predict the next big financial crash? There has been a lot of talk about a big pending financial crash due to the slowing global economy, low interest rates, rising debt levels, etc.  Now I'm wondering:

Has anyone done any analysis to predict exactly when the next big crash / credit crunch will be?

Specifically, what indicators have analysts been tracking to predict when the next crash will happen?  Has anyone agreed or suggested what will be the critical thresholds, and/or likely trigger(s)?

Ideally I am looking for some measure of systemic risk which effectively gauges how unsustainable a system is, or rather, how long an economic system can be sustained before it is likely to collapse.

I have made my own analysis and prediction based on long-term trends in slowing growth vs rising debt, but has anyone done this kind of analysis before?

A useful principle to have in mind here is the so called 'volatility paradox´ oft-cited by Marcus Brunnermier (Princeton prof):

The idea is as follows: a) financial institutions are in the business of taking reasonable risks; b) when the financial system is deemed very stable, then it makes sense for financial institutions to engage in risky activities, because, if the system is stable those risky bets are manageable, reasonable bet; c) when all financial institutions jointly engage in risky activities, the system becomes unstable. In other words, safety engenders individual risk-taking, which creates aggregate risk. This works the other way too: riskiness engenders risk averse attitudes, which lead to a stable system.

If you believe this story then you get some insight into why its difficult to predict crises: they happen when risks build up during periods of safety and stability...
