This work studies a Robust Multi-product Newsvendor Model with Substitution (R-MNMS), where the demand and the substitution rates are stochastic and are subject to cardinality-constrained uncertainty sets. The goal of this work is to determine the optimal order quantities of multiple products to...

This paper studies a multi-product newsvendor problem with customer-driven demand substitution, where each product, once run out of stock, can be proportionally substituted by the others. This problem has been widely studied in the literature, however, due to nonconvexity and intractability,...

Prior studies have linked long-term reversals to the magnitude of locked-in capital gains, suggesting that reversals are driven by tax effects and not overreaction. We show that locked-in capital gains do not explain the reversals in winners when winner returns are based intangible information...
