Inflation targeting and stock market development: matching in difference and difference analysis in developing economies

This study examines the effect of inflation targeting adoption on stock market capitalization in 39 developing countries from 1995 to 2023. Baseline propensity score matching with two-way fixed effects shows positive but sometimes insignificant effects. Robustness checks excluding the 2008–2009 Global Financial Crisis, hyperinflation episodes, and both combined often yield larger and more significant estimates. To address concerns about staggered policy adoption, we use the Staggered Difference-in-Differences estimator, finding that significance emerges five to ten years after adoption. Results suggest IT supports financial development by enhancing investor confidence and macroeconomic stability, especially in lower-volatility environments.
