I love this time of year. Here is a video I show that the same economists that made the Keynes vs. Hayek videos, so there is an Austrian bent. After I show the video, we discuss the difference in macroeconomic policies. The students all think I am an economics nerd, which I am, and they like the songs used.
At the end, there is a photo of "Macro Santa." The joke is typically lost on the students. The voiceover says, "And remember, the one person to create presents out of nothing is Santa himself." The joke here is that they used someone who looked like then Chairman of the Federal Reserve Ben Bernanke. This is a shot at the Federal Reserve, as they can create money from nothing due to the fact that our money is fiat. Something else to discuss with your classes.
