Policy reforms enacted in the early and mid 1990s reduced income gaps at the bottom to below their 1978 value (as measured by the p50/p10 ratio, not reported here). But no equalising effects of policies could be discerned for the upper part of the distribution (p90/p50 ratio). For the period as a whole, tax policy changes appear to have slightly exacerbated trends towards widening income gaps at the top. The interpretation is that the tax system in the mid-2000s would have been somewhat more redistributive if policy makers had implemented no reform at all and had, instead, simply adjusted all monetary tax parameters in line with inflation.
