a) Specification (I) uses self-assessed health as the only health need indicator, while (II) includes additional health information. t-values are given in italics below each index. Statistically significant indices at 5% level are shown in bold. Horizontal inequity indices (HI) are based on equations (1)-(3). To compute HI, we apply eq. (1) but replace y_i in (1) with from eq. (3).
