La Crisi dei mutuisubprimee le sue implicazioni nella gestione e regolamentazione del rischio
Full text linkWe expose a historical and theoretical framework for the concepts of probability, risk and financial bubbles. Then, we focus on the subprime mortgage crisis in the United States and we provide: a comparison with similar past crises, an analysis of the causes and consequences, a review of the Basel Accords on banking capital regulations in the light of reform proposals. In appendix, a martingale model for bubbles in financial markets is finally provided
Gli atteggiamenti dei giovani marchigiani di fronte al tema della donazione. Un'analisi del progetto regionale Donaction
No full textDonaction is a project promoted by the Marche Region and by several voluntary associations which aims to inform and raise awareness among the young attending secondary schools about donation. The article presents the results of a questionnaire administered to more than 1000 students participating in the project and a series of semi-structured interviews in order to verify both student’s attitudes about donation practices and the effectiveness of the project itself. The research identifies a series of factors that can have a positive role on young generations’ perceptions about donation
The Ecology of defensive medicine and malpractice litigation
Full text linkWe analyse the relations between defensive medicine and medical malpractice litigation by an
evolutionary game between physicians and patients. When medical treatment fails, patients may
suit the physician and seek compensation. Conversely, physicians may prevent negligence charges
by practising defensive medicine. We study the population dynamics and find the Nash equilibria
and their Pareto-ranking. Furthermore, we show that, when the mixed-strategy equilibrium exists,
then the shares of defensive physicians and litigious patients exhibit time-evolution paths similar to
prey-predator relations in the Lotka-Volterra model, in which physicians can be seen as preys and
litigious patients as their predators. Then, defensive physicians can be seen as adapted preys who
improved their Darwinian fitness through mutation. The increase in adapted preys (i.e.defensive
physicians) decreases predators’ fitness leading to a decrease in predators (i.e.litigious patients).
In this context, we show that perfect cooperation with neither defensive physicians nor litigious
patients can be the social first best. Our results may explain heterogeneous findings in empirical
literature on these phenomena
