Agent's optimization in unique-contract principal-agent problem with adverse selection is recast as stochastic target problem, enabling principal's objective as stochastic optimal control with partial information and state constraints.
In continuous-time Kyle with privacy noise, cumulative expected transfer |Π_M| equals σ_v σ_ε² / √(σ_u² + σ_ε²) under Markovian linear equilibrium, analogous to LVR.

The Privacy Subsidy in Continuous-Time Kyle: Cumulative Welfare under Noise-Perturbed Order-Flow Observation
In continuous-time Kyle with privacy noise, cumulative expected transfer |Π_M| equals σ_v σ_ε² / √(σ_u² + σ_ε²) under Markovian linear equilibrium, analogous to LVR.
