Abstract

Waiting time is a rationing mechanism that is used in publicly funded healthcare systems as a mean to ensure equal access for equal need. However, several studies suggest that individuals with higher socioeconomic status wait less. These studies typically measure patients' socioeconomic status as an aggregate measure from patients' residential area and the results are hence vulnerable for aggregation biases. We shed light on the magnitude of the aggregation bias by analyzing socioeconomic gradients in waiting times when education and income are measured on three different levels: the individual level, the population cell level, and the municipal level. Our individual level socioeconomic gradient is modest compared with the literature. When socioeconomic status is measured on an aggregate level, we observe stronger associations with socioeconomic variables and less accurate estimates. A researcher who only has access to the aggregate data runs the risk of overstating the magnitude of the socioeconomic gradients.

期刊介绍: This Journal publishes articles on all aspects of health economics: theoretical contributions, empirical studies and analyses of health policy from the economic perspective. Its scope includes the determinants of health and its definition and valuation, as well as the demand for and supply of health care; planning and market mechanisms; micro-economic evaluation of individual procedures and treatments; and evaluation of the performance of health care systems. Contributions should typically be original and innovative. As a rule, the Journal does not include routine applications of cost-effectiveness analysis, discrete choice experiments and costing analyses. Editorials are regular features, these should be concise and topical. Occasionally commissioned reviews are published and special issues bring together contributions on a single topic. Health Economics Letters facilitate rapid exchange of views on topical issues. Contributions related to problems in both developed and developing countries are welcome.
