The rules are as I explained yesterday. I'm looking for the clearest possible explanation of financial derivatives, how they work in our world, and their place in the financial crisis. Do not think of this as a school essay assignment. Think of it as a conversation. This thread is the best model. Those of you who are ignorant like me can, and should, still participate. Please ask questions. I'm not looking at a single post in isolation; I'm looking at the whole thread.
