Here are two resources worth your attention, particularly if you do the Fed Challenge. (HT to Greg Mankiw on both of these, by the way.)
The first is a post on Dr. Mankiw's blog showing charts from the St. Louis Fed. I expect (and fervently hope) that these spikes disappear in the not too distant future. But they are representative of what the Fed does in a financial crisis. You might want to have students also look at reserve positions at banks and fed funds lending activity.
The second is for when you and the team have been working hard and need a break and a laugh. (This should be particularly meaningful to those who were in the Seventh District Fed Challenge when I was still in Chicago.)
Are there negatives to using the video? I look forward to your thoughts.
