Identifying demand for health resources using waiting times information
利用平均等待时间差异识别健康服务需求的决定因素，通过半参数选择模型处理等待时间的内生性，为英国卫生服务分配提供更准确的依据。
In this paper the differences in average waiting times are utilized to identify the determinants of demand for health services. The equilibrium waiting time framework is used, but the full equilibrium assumption is relaxed by selecting areas with low waiting times and by estimating a (semi-)parametric selection model. Determinants of supply are used as instruments for the endogeneity of waiting times. A model for the demand for acute services at the ward level in the UK is estimated. The model estimates, and their implications for health service allocations in the UK, are contrasted against more standard allocation models. The present results show that it is critically important to account for rationing by waiting times when identifying needs from care utilization data. Copyright © 2000 John Wiley & Sons, Ltd.
