We use surveys of households and health-care facilities conducted in the same area at the same time to determine which characteristics of providers attract users of contraceptives. By using the full-information maximum-likelihood technique to jointly estimate choice of contraceptive method and choice of provider, we avoid self-selection bias. Results support the need for modeling quality and for jointly estimating the choice of contraceptive method and the choice of provider to avoid biased estimates of coefficients. The results suggest that for the Cebu, Philippines region, small local clinics that focus on family planning tend to be most favored by clients.
我们通过同时对同一地区的家庭和医疗保健机构进行调查,来确定提供者的哪些特征吸引避孕药具使用者。通过使用全信息最大似然技术来联合估计避孕方法的选择和提供者的选择,我们避免了自我选择偏差。结果支持对质量进行建模以及联合估计避孕方法的选择和提供者的选择以避免系数估计出现偏差的必要性。结果表明,对于菲律宾宿务地区,专注于计划生育的小型当地诊所往往最受客户青睐。
