It extends the previous results to investigate the case when the actual additive demand may attain negative values due to high prices or considerable, negative demand shocks. The results indicate that the general optimal solution may differ to the solution corresponding exclusively to the non-negative realizations of demand.}, title={The Pandemic-Type Demand Shocks in the Mean-Variance Newsvendor Problem}, URL={http://www.czasopisma.pan.pl/Content/122783/PDF/656_corr.pdf}, doi={10.24425/mper.2022.140876}, keywords={Production planning and control; Inventory;, Newsvendor, pricing, Stochastic additive demand}, }
