During the recent financial crises, dubbed the Great Recession, the Federal Reserve Bank and central banks throughout the world embarked on the use of extraordinary or non-traditional monetary policy tools to prevent the financial crises from worsening. Pick one of the major central banks (Federal Reserve, Bank of Japan, or the European Central Bank) and describe the tools they used to prevent the Great Recession from worsening. Do you agree or disagree with what they did? In other words, should they just have allowed the markets to correct without any interference to remove any excess that were built up prior to the crises?
