counter-cyclical capital buffer
Counter-cyclical capital buffers are increasingly popular new "macroprudential" tools. However, there is limited empirical evidence on both the intended and unintended consequences of using these buffers. During the pre-crisis period (2002--2007), South Africa increased capital adequacy ratios to curb rapid credit extension, and so provides a useful test case. Using a new data set from that period, this paper extends a standard large-scale macroeconomic model to include capital adequacy ratios as a policy lever.
