Negative volatility and the Survival of Western Financial Markets
AbstractThe paper discusses situations where certain parameters are given values that are outside their natural ranges. One case is obtained when plugging in a negative value for the volatility parameter in the Black and Scholes formula. This leads to seemingly "new" results. A different setting is considered related to the developments in time of biological populations. Here deterministic models lead to chaotically fluctuating population sizes, which came as a surprise to workers with population data. It is argued that the origins for the seemingly new and original results may be related.
