Viscosity Solutions and Mean Field Equilibria for Nonlocal Stochastic Control Under Catastrophe and Replacement-Cost Risk
We develop a stochastic-control and mean field game framework for catastrophe insurance under stochastic replacement-cost risk. Insurer surplus follows a controlled jump diffusion in which catastrophe losses are scaled by an exogenous mean-reverting replacement-cost factor and attenuated through physical hedging. We es...
