Measuring horizontal inequity in health care using Belgian panel data

We estimate the determinants of utilisation of physician and hospital services in Belgium using four different regression techniques. We apply a one- and two-part panel count data model, and a one- and two part cross-section count data model. We conclude that the two-part panel count data model is most appropriate as it controls for unobserved heterogeneity and allows for a two-part decision making process. The estimates of the determinants of utilisation of health care are then used to calculate indices of horizontal inequity. We find that there is little difference between the indices based... Mehr ...
