Résumé
A seller sells an object over time but is uncertain how the buyer learns their willingness-to-pay. We consider informational robustness under \textit{limited commitment}, where the seller offers a price \textit{each period} to maximize continuation profit against worst-case information arrival. Our formulation maintains dynamic consistency by considering the worst case \textit{sequentially}. Under general conditions, we characterize an essentially unique equilibrium where the buyer does not delay to learn more later. Furthermore, we identify a condition that ensures the equilibrium price path is ``reinforcing,'' so even dynamically inconsistent information arrival would not lower the seller's payoff below the equilibrium level.
