Bubbles

Worthwhile Canadian Initiative: We know the economy needs a bubble; but how big?: "Mr Ponzi issues a financial asset. Assume that the demand to hold that asset grows at the same rate as GDP. If people are willing to hold that asset at a rate of return less than the growth rate of GDP, Mr Ponzi can run a sustainable Ponzi scheme. He can issue new assets to pay the interest on the existing assets, and still issue a few more to provide some income for himself. Another name for a sustainable Ponzi scheme is a rational bubble."
