摘要：We examine inequality persistence in a multi-country unbalanced panel frameworkusing a battery of stationarity and long-run memory tests. Inequality is measuredby the (gross and net) Gini indices of income inequality. Results suggests thatwe cannot reject a unit root in the inequality measures. This applies to both gross andnet indices: thus whilst redistributive measures have reduced the level of inequality,they have not sufficiently modified its apparent unit root. A more likely conclusionis that inequality measures are exceptionally persistent if not strictly speaking a unitroot. Thus shocks to inequality have very long-lasting effects. We also introduce anew panel stationarity test useful for series subject to unknown structural breaks
