"As no rational agent would be willing to take part in the last round in a finite economy, it is difficult to design Ponzi schemes that are certain to explode. This paper argues that if agents correctly believe in the possibility of a partial bailout when a gigantic Ponzi scheme collapses, and they recognize that a bailout is tantamount to a redistribution of wealth from non-participants to participants, it may be rational for agents to participate, even if they know that it is the last round. We model a political economy where an unscrupulous profit-maximizing promoter can design gigantic Ponzi schemes to cynically exploit this "too big to fail" doctrine."

What market has grown from $900 billion in 2000 to more than $45.5 trillion and is completely unregulated? Welcome to the world of Credit Default Swaps. Speculative derivatives have been described as "financial weapons of mass destruction" by some guy named Warren Buffet. Some people wonder how you can have "$1 trillion in swaps bet on the success or failure of GM when the entire market cap of GM is a mere $15 billion." Credit Default Swaps are being triggered from Northern Rock in the UK to ANZ Bank down under as the "subprime" crisis unravels. AIG's CDS loss portfolio has already climbed to $5 billion from a previsouly estimated $1 billion.

A primer on the global derivatives market, the City of London, and the credit crunch:

"In 2003 the total size of the world economy was $49,000,000,000,000. The total size of the derivatives being traded was $85,000,000,000,000. In other words, derivatives today are worth far, far more than the total economic activity of the planet. More than $1,000,000,000,000 of derivatives are bought and sold every day. Every single thing that can be traded through derivatives, is."
