报告摘要和内容:

Under discrete choice models (DCMs), a decision maker is tasked with selecting a single alternative, which is appropriate for situations such as lodging, transportation, and other contexts where only one option can be chosen. However, DCMs have a limitation - they do not directly apply to multiple purchases. In practice, consumers often buy multiple products. Therefore, we propose a threshold choice model, which assumes that the representative consumer has additive utilities and aims to maximize her expected surplus while ensuring that the expected number of purchased products is bounded above by an exogenously specified number (the model can be extended to a budget constraint or to multiple constraints). We demonstrate that the basic model reduces to another where the consumer selects all products whose net utility exceeds a product-specific threshold. We also show that a common threshold is, in fact, optimal.
