摘要：We propose a framework for studying sequential search with a finite deadline, where agents search both sequentially and simultaneously.  We show several important applications of this framework.  [1] Sequential Search Auction, where a seller searches for potential buyers by a finite deadline.  We show that the optimal search mechanism is characterized by decreasing reserve prices and increasing search intensities.  The results help explain the pervasiveness of negotiation as a dominant selling-process in many markets.  [2] Optimal Search Intensity, where an agent chooses search intensity adaptively in each period.  We characterize the fallback value and the deadline effect that jointly determine the dynamics of optimal search intensity.  [3] Time Preference.  In our search model, we provide a rational foundation for procrastination and impatience, for which researchers normally resort to behavioral explanations.  [4] R&D Tournament.  Using our framework, we investigate the sequential and adaptive choices of agents’ effort levels in dynamic contests, which greatly extends the current literature that focuses on binary decision rules.
