Hedging Large Risks Reduces the Transaction Costs
As soon as one accepts to abandon the zero-risk paradigm of Black-Scholes, very interesting issues concerning risk control arise because diierent deenitions of the risk become unequivalent. Optimal hedges then depend on the quantity one wishes to minimize. We show that a deenition of the risk more sensitive to the extreme events generically leads to a decrease both of the probability of extreme...

Risk-benefit assessment is a routine requirement for research ethics committees that review and oversee biomedical research with human subjects.

In this article, we address the question of whether there are any reasonable criteria f...
متن کاملTaking risks with translational research.
The recent bankruptcy filing by deCODE, a company with an exceptional pedigree in associating genetic variance with disease onset, highlights the commercial risks of translational research. Indeed, deCODE's approach was similar to that adapted by academic researchers who seek to connect genetics and disease. We argue here that neither a purely corporate nor purely academic model is entirely app...
متن کامل0 Hedging large risks reduces the transaction costs
As soon as one accepts to abandon the zero-risk paradigm of BlackScholes, very interesting issues concerning risk control arise because different definitions of the risk become unequivalent. Optimal hedges then depend on the quantity one wishes to minimize. We show that a definition of the risk more sensitive to the extreme events generically leads to a decrease both of the probability of extre...
متن کاملPeriodontal disease with treatment reduces subsequent cancer risks.
