內(nèi)容摘要

In this talk, we discuss the threshold effects on the consideration set formation for consumers and the associated operations decisions for firms. Under the threshold effects, consumers first form their (heterogeneous) consideration set: If an alternative with significantly low utility is dominated by another one, it will not be included in the consideration set. We develop a maximum likelihood based estimation to calibrate the proposed threshold model and further establish its statistical properties such as consistency and asymptotic normality under mild conditions. An efficient EM algorithm is also developed to handle the scenario with incomplete sales data. For the pricing problem, we show the quasi-same-markup/same-utility policy is optimal; for the price competition, there may exist zero, one, two, or infinite Nash equilibria, depending on the magnitude of the threshold effects. In addition, we characterize the optimal strategies and provide efficient solutions for the associated assortment optimization problems under the threshold effects.
