On the penalty function and on continuity properties of risk measures / M. Frittelli, E. Rosazza Gianin. - In: INTERNATIONAL JOURNAL OF THEORETICAL AND APPLIED FINANCE. - ISSN 0219-0249. - 14:1(2011), pp. 163-185. [10.1142/S0219024911006309]
Abstract:
We discuss two issues about risk measures: we first point out an alternative interpretation of the penalty function in the dual representation of a risk measure; then we analyze the continuity properties of comonotone convex risk measures. In particular, due to the loss of convexity, local and global continuity are no more equivalent and many implications true for convex risk measures do not hold any more.
