Abstract: The aim is to study the properties of a family of risk measures recently introduced in the financial literature under the name of $\Lambda$-Value at Risk, that provides an interesting generalization of the usual quantiles. We provide an axiomatic foundation for $\Lambda$-quantiles, similar in spirit to analogous axiomatizations of the usual quantiles. Under mild technical conditions, we characterize the class of scoring functions that are strictly consistent with the $\Lambda$-quantile interval, generalizing the corresponding class of GPL functions that elicits the usual quantiles. Finally, we discuss financial applications of $\Lambda$-quantiles forecasting by means of regression techniques.
