Keynes – Animal Spirits

Decisions often made out of a spontaneous urge to react

Cornerstone of economic theory is consumer confidence

The key, therefore, is to revive confidence in markets.

This should not tip over to arrogance!

Confidence

Bubbles

Economic Froth driven by human behaviour acting irrationally

Bubbles are created – don’t match the law of demand!

Story of 2008...

Conclusions

Greed ? Is it an animal spirit? Was it rational to start selling sub-

prime? Was it a good idea invest in a bubble

based on other people’s investment?
