Estimating the Demand for Service Bundles under Three‐Part Tariffs
构建了一个两阶段离散/连续选择模型来估计三部定价下消费者对服务捆绑的需求，并用中国无线服务提供商的数据进行实证分析，发现可互换单位的三部定价不会显著损失收入。
Consumers may face demand uncertainty when choosing a service plan under three‐part tariffs, and preferences for multiple services may be inter‐dependent. To examine such a demand system, we construct a two‐stage discrete/continuous choice model for service bundles, allowing for interactive utility and preference correlations. Implementing a piecewise maximization approach to consumers’ non‐differentiable utility maximization problem, we estimate the model via simulated method of moments. We empirically illustrate the model using data from a Chinese wireless service provider. Our counterfactual analysis shows that the three‐part tariffs with interchangeable units show no significant loss of revenue, compared to existing tariffs.
