Abstract:​ Modern digital platforms increasingly record not only the final choice made by a decision maker but also traces of the decision process itself, such as search depth, browsing histories and response times. We study how such process-level data can be used to recover the underlying sequential search strategy. We model the observable as a joint distribution over choices and search depth generated by repeated search-and-choice decisions. Under weak observational assumptions, we provide a nonparametric characterization of optimal sequential search. Our results identify the underlying reservation-value ordering, derive testable implications for observed choice-process data. The framework provides a revealed-preference foundation for learning latent search policies from process data and has applications to the analysis of digital platforms, recommender systems and interventions in sequential decision making.

​About the Speaker: Prof. Saptarshi Mukherjee is a Professor of Economics at Indian Institute of Technology Delhi. He graduated from the Indian Statistical Institute (Delhi). He works on mechanism design, social choice, game theory, bounded rationality and teaches microeconomics, game theory and mathematical economics.

​We look forward to your active participation.
