报告内容摘要

We propose and   study a threshold utility model (TUM) where consumers buy any product whose   net utility exceeds a non-negative, product-specific threshold. The   thresholds are selected to maximize the expected surplus of the   representative consumer subject to a bound on the expected number of selected   products. We show that at optimality the thresholds are product-invariant and   that the generalized extreme value (GEV) model is a special case of the TUM.   The TUM is shown to yield higher consumer surplus than observing all the   products' utilities and selecting the best when the bound is an integer. The   model can also be applied with proxy utilities as in on-line shopping and   portfolio management. Comparative statics are applied to the threshold, the   purchase probabilities and the expected surplus. Extensions to multi-unit   TUM, weighted TUM, multiplicative TUM, discontinuous utility and   bound-induced copulas are also considered. We also providesolutions to the pricing and assortment   optimization problems under the TUM. (This is a joint work with Guillermo   Gallego.)
