Inflation targeting, Monetary policy, and Inequality

This paper explores whether the transmission from monetary policy to income inequality may depend on the adoption of Inflation Targeting (IT) regimes. Using an interacted panel VAR, we find that expansionary monetary policy shocks reduce income inequality in countries that have switched to IT regimes. In contrast, in non-IT regimes the same shock is associated with a short-lived increase in income inequality. A decomposition of transmission channels indicates that the employment channel is the primary equalizing mechanism under IT, as expansionary shocks generate stronger improvements in labor market conditions. The financial channel operates in the opposite direction but is quantitatively smaller. We further show that the inequality-reducing effects of monetary policy are not replicated by other institutional features often associated with credibility, such as central bank transparency or central bank independence. Our findings are robust to alternative identification schemes, broader classifications of IT regimes, controls for self-selection into IT adoption, and to conditioning on different inflation environments.
