2. Consider a society consisting only of Helen, who allocates her time between sewing dresses and baking bread.

Define the following terms (you may need to look them up in the book or use wikipedia): bank run, certificate of deposite, T-Bill, market risk, federal funds rate, security.
Describe how our current crisis is like a bank run (hint: think about risk perception).
Outline how you would explain the current crisis to a friend or family member.
|HW 6||Due Wednesday, October 8||Read and summarize one economists take on the current financial crisis. For this, print at least the first page of the editorial you use, and type or write your summary. You should write between 1 and 2 pages. Please type it, and save your work, we will extend this assignment next week. You do not have to summarize the whole thing, but rather, show how what we've learned in class applies to the economists' analysis. You should define any terms that the average college student does not know.|
You may choose any publication, but avoid blog posts. Authors of economics blogs often write elsewhere as well, so if you wish to use a blogger, use what they've published in a newspaper, magazine, or syndicated-type website (project syndicate, salon, etc). A good place to start is Greg Mankiw's roundup of commentaries here.

2) Also listen to this episode. Define money market mutual funds. Why are they important? How is what happened in the past month to these like a bank run? Define credit default swap. Why are they important? How is what happened in the past to these month like a bank run? If the commentary you reviewed discuss either of these, does it add anything to the NPR show? What? If not, does this reflect poorlly on the commentary? Why do banks fear the plan that passed?
