Firm's Static Behavior under Dynamic Demand
This study investigates in what cases a firm's dynamic price-setting behavior can be approximated as static under dynamic demand, by developing a dynamic discrete choice model. Under dynamic demand with random utility shock following Gumbel distribution, this study shows that an oligopolistic firm's optimal price-setting behavior is well approximated by the static one with no strategic consideration, when consumers' conditional choice probabilities (CCPs) of choosing the firm's product are small for all consumer types and state variables. If the condition does not hold, the firm's behavior might be far from static.
