Jointly with the Council on Economic Policies and the Swiss National Bank, the Study Center Gerzensee organized a conference on Aggregate and Distributive Effects of Unconventional Monetary Policies. The program can be viewed here.
On his blog, John Cochrane reports about a Hoover panel including him, Charles Plosser, and John Taylor.
Cochrane focuses on the liability side. He favors a large quantity of (possibly interest bearing) reserves for financial stability reasons. Plosser focuses on the asset side and is worried about credit allocation by the Fed, for political economy reasons. Taylor favors a small balance sheet. Cochrane also talks about reserves for everyone, but issued by the Treasury.
