Risk measures based on weak optimal transport

The paper explores convex risk measures with weak optimal transport penalties, demonstrating explicit representations via nonlinear transformations of loss functions. It delves into computational aspects, discussing approximations using neural networks and applies these concepts to diverse examples. Finally, it demonstrates practical applications in insurance and finance for worst-case losses and no-arbitrage pricing beyond quoted maturities.
