"Last updated: March 21, 2025." Includes bibliographical references (pages 38-41). "We propose a new approach to estimating the random coefficient logit demand model for differentiated products when the vector of market-product-level shocks is sparse. Assuming sparsity, we establish nonparametric identification of the distribution of random coefficients and demand shocks under mild conditions. Then we develop a Bayesian estimation procedure, which exploits the sparsity structure using shrinkage priors, to conduct inference about the model parameters and counterfactual quantities"--Abstract, page ii.
