内容简介：We observe nominal price rigidity in tobacco markets across China. The monopolistic seller responds by adjusting product assortments, which remain unobserved by the analyst. We develop and estimate a random coefficient demand model that incorporates assortment discrimination and nominal price rigidity. Our empirical findings indicate that consumers are much more responsive to price changes than predicted by a conventional model. Simulated tax increases reveal that neglecting the role of endogenous assortments results in underestimations of the decline in higher-tier product sales, incorrect directional predictions of lower-tier product sales, and overestimation of tax revenue by more than 50%.
