We consider in details the case where the lower obstacle is a deterministic function of $(Y,\\E[Y])$ and discuss the more general dependence on the distribution of $Y$. Under mild Lipschitz and integrability conditions on the coefficients, we obtain the well-posedness of such a class of equations. Under further monotonicity conditions, we show convergence of the standard penalization scheme to the solution of the equation, which hence satisfies a minimality property. This class of equations is motivated by applications in pricing life insurance contracts with surrender options.", "revisions": [ { "version": "v1", "updated": "2019-11-14T13:07:35.000Z" } ], "analyses": { "keywords": [ "reflected backward stochastic differential equations", "mean-field reflected backward stochastic differential", "lower obstacle", "standard penalization scheme", "pricing life insurance contracts" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
