“…In the literature of risk measures, many results on the characterization of elicitable risk measures are obtained via characterizing the CxLS property in dimension one; see Weber (2006), Bellini and Bignozzi (2015), and Delbaen, Bellini, Bignozzi, and Ziegel (2016) for convex risk measures, Ziegel (2016) for coherent risk measures, Kou and Peng (2016) and Wang and Ziegel (2015) for distortion risk measures, Liu and Wang (2020) for tail risk measures, and Fissler, Hlavinová, and Rudloff (2019a, b) for set‐valued risk functionals. As far as we are aware of, studies dedicated to CxLS in the multidimensional setting are not found in the literature, although multidimensional elicitability has been a popular topic; see Lambert, Pennock, and Shoham (2008), Fissler and Ziegel (2016), Nolde and Ziegel (2017), and Acerbi and Szekely (2017) for multidimensional elicitability and their statistical implications.…”
