Whereas studies on regional inequality tend to focus on income disparities,
we investigate regional inequality in Spain with respect to health facilit
ies. In this study we examine trends in regional inequality over the period
1964 to 1991 during which fundamental changes in health policies were impl
emented. We follow a multidimensional approach in the sense that several in
dicators of health facilities are considered. Regional inequality is measur
ed by means of Theil's second measure of multidimensional inequality. The p
artial common principal components (PCPC) model is used to construct the we
ights for this measure whenever appropriate, and principal component analys
is (PCA) is used when otherwise. The PCPC model is a generalisation of the
classical method of PCA for several samples (years). Component coefficients
are estimated by assuming that the first component is common for all years
. Spatial inequality between regions as well as within regions is analysed
to highlight the role of policy and other regional characteristics. Spatial
spillovers are analysed by including the effects of health facilities in n
eighbouring regions. The analysis shows that the health policies of the Spa
nish government in the 1980s and decentralisation of power may have helped
to reduce regional inequality, although no firm conclusions can be drawn ye
t.
