Representation of forward performance criteria with random endowment via FBSDE and application to forward optimized certainty equivalent
We extend the notion of forward performance criteria to settings with random
endowment in incomplete markets. Building on these results, we introduce and
develop the novel concept of forward optimized certainty equivalent (forward
OCE), which offers a genuinely dynamic valuation mechanism that accommodates
progressively adaptive market model updates, stochastic risk preferences, and
incoming claims with arbitrary maturities. In parallel, we develop a new methodology to analyze the emerging stochastic
optimization problems by directly studying the candidate optimal control
processes for both the primal and dual problems. Specifically, we derive two
new systems of forward-backward stochastic differential equations (FBSDEs) and
establish necessary and sufficient conditions for optimality, and various
equivalences between the two problems. This new approach is general and
complements the existing one based on backward stochastic partial differential
equations (backward SPDEs) for the related value functions. We, also, consider
representative examples for both forward performance criteria with random
endowment and forward OCE, and for the case of exponential criteria, we
investigate the connection between forward OCE and forward entropic risk
measures.
