There has been a lot of Fedspeak recently. Pointing to each one individually would take a long time. Here are some good ones:
1. Bernanke compares 1970′s with recent times
2. Bernanke’s controversial speech where he says USD shouldn’t depreciate more as it leads to imported inflation
3. Lacker (Richmond Fed) on financial stability and moral hazard
4. Charler Plosser (Philadelphia Fed) on financial innovation, financial models and moral hazard
All are quite good and worth a quick read.
