2. Capital Flows and Risk-taking channel
Main contribution
Borio & Zhu (2012) on the risk-taking channel :
The analysis is very much of a speculative, exploratory nature. We do not develop any new specific model or present new econometric evidence, but simply highlight what appear to us as under-researched aspects of the issues.

4. Some issues – VAR estimation
Why using a real federal fund rate ?
Our empirical investigation consists of recursive vector autoregressions (VAR) examining the dynamic relationship between the CBOE VIX index of implied volatility on the S&P index options, the real Feds Funds target rate of the US Federal Reserve, and a proxy for the leverage of global banks. The real Fed Funds target rate is computed for the end of the quarter as the target Fed Funds rate minus the CPI inflation rate.”
