I spent some time with an OLG model, and after a while I understood the model. At the very least, I could clearly see how wealth was being transferred from the young to the old.

And sometimes it takes me hours to get what Nick is saying in a model that probably took him minutes to knock off. In other words, in general, I am in awe of Nick's depth of understanding of the macro-economy. But...

The fact that I can create a model in which 1) occurs no more proves that whistling causes mass sho...
