Capital controls in the 21st century, by Barry Eichengreen, Andrew K Rose, Vox EU: Summary Since the global financial crisis of 2008–2009, opposition to the use of capital controls has weakened, and some economists have advocated their use as a macroprudential policy instrument. This column shows that capital controls have rarely been used in this way in the past. Rather than moving with short-term macroeconomic variables, capital controls have tended to vary with financial, political, and institutional development. This may be because governments have other macroeconomic policy instruments at their disposal, or because suddenly imposing capital controls would send a bad signal.
