使用来自欧洲共同体家庭小组的三波数据，本文估计了12个欧洲国家对医生服务方程的需求。我们专注于选择最合适的计量经济学规范访问全科医生和专家之间的两部分和潜在的阶级模型。从这两种类型的医生的服务需求之间的区别合金的我们区分的情况下，两部分表现更好比潜在类模型，证据不同于以往的发现在文献中。结果表明，潜在类别模型比两部分模型更适合估计全科医生的利用率，而对专家的访问则相反。版权所有:John Wiley Sons, Ltd。
Using three waves of data from the European Community Household Panel, this paper estimates demand for physician services equations for 12 European countries. We focus on the selection of the most appropriate econometric specification for visits to general practitioners and to specialists among two-part and latent class models. The distinction between the demand of services from these two types of physicians alloy's us to distinguish cases in which two-part perform better than latent class models, evidence which is different from previous findings in the literature. The results suggest that latent class models are more appropriate than two-part models to estimate general practicioners Utilisation while the opposite is found for visits to the specialists.
