This paper examines the effect of inflation targeting (IT) on income distribution in a panel of 70 countries. Employing panel regressions and a variety of propensity score matching methods, we find strong evidence that incomes became more unequal in IT‐adopting countries relative to countries that did not adopt IT. Panel regressions suggest that Gini coefficients increased by 0.25%–0.57% and the share of income of the top 1% and 10% of households increased by 0.7% in IT adopter countries. Using propensity score matching methods, IT has been associated with a relative rise in Gini coefficients of about 1–2 percentage points, and a relative increase in the share of national income going to the top 1% and 10% of households by about 11–13 percentage points and 13–17 percentage points, respectively. The results are robust to changes in country sample and alternative estimation methodologies.
