This paper proceeds as follows. We first identify the essential services provided by a financial system and then derive the characteristics of the system that would exist in a technologically advanced society unfettered by nonneutral taxes and regulations. Next we consider how taxes and...

Recent evidence suggests an increasing risk of natural disasters of the magnitude of hurricane Katrina and Sandy.
