How do Active managers argue they are still relevant and how are they strategically responding? 3) Why would haircuts' on collateral increase sharply during a financial crisis? 4) What are the arguments for and against the Federal Open Markets Committee (FOMC) releasing directives immediately after their 6-weekly meeting? 5) What are the advantages and disadvantages of quantitative easing as an alternative to conventional monetary policy when short-term interest rates are at the zero-lower-bound
