On the optimality of a duty-to-rescue rule and the cost of wrongful intervention

► In civil (common) law countries, the principle of duty to rescue does (not) apply. ► We examine this difference by taking into account the cost of wrongful intervention. ► We compare three policy options: rule, no rule, and encouraging would-be rescuers. ► We explain the choices made in the USA and France as to whether to use rescue laws.
