We propose a new parametrization of Quantum Decision Theory (QDT), based on Rank Dependent Utility Theory (RDU). Using experimental data made of choices between pairs of lotteries, we compare QDT with "classical" decision theories, RDU and Cumulative Prospect Theory (CPT). At the aggregate...

If prevention expenditures may … increased dependence increases aggregate prevention expenditures, but not necessarily prevention expenditures for each risk due …
