Currency crises, capital-account liberalization, and selection bias

Are countries with unregulated capital flows more vulnerable to currency crises? Efforts to answer this question properly must control for self-selection bias, because countries with liberalized capital accounts may also have sounder economic policies and institutions that make them less likely to experience crises. We employ a matching and propensity-score methodology to address this issue in a panel analysis of developing countries. Our results suggest that, after controlling for sample selection bias, countries with liberalized capital accounts experience a lower likelihood of currency crises.
