The geometry of heterogeneous extremes : optimal transport and entropic design

Buhai, Sebastian - 2026

Extreme outcomes depend not only on shock tails but also on heterogeneity in how many opportunities agents get to sample. In the mixed-Poisson search framework, a randomly drawn agent's normalized maximum converges to Hγ,F (x) = P0 (vγ (x)) , a Laplace-transform mixture of a classical...

Extremal expected shortfall regressions : inference and an application to health care spending

Hoga, Yannick; Karlsson, Martin - 2025

This paper proposes feasible inference methods for extremal expected shortfall (ES) regressions. While standard ES regressions consider a fixed probability level, in extremal ES regressions the probability level becomes more extreme as a function of the sample size. We show that in extremal ES...
