This exam may be completed collaboratively. If you choose to do so, the name of each person who participated must appear on the first page of your answer paper. Each person may participate in one and only one group. Note that collaborative exams will be judged according to a high standard, both in terms of content and presentation (in other words, no spelling errors, grammatically incorrect sentences, etc.)
Answers should be typed in an MS-Word document (IBM, not MAC) and emailed to me by midnight May 10th. Earlier responses are appreciated (the school needs to figure out who will graduate with what honors). Answer as fully as possible (given the page limits), in proportion to the number of points that each question is worth. For example, if your answer to the Goliath Effect question is 1/2 typed page, double-spaced, then your answer to the Granovetter question should be about 2 typed pages. Please observe the maximum page limits given for each question (which assume double-spaced, 12 point font, 1-inch margins). Given the maximum page limits, it is important to write in the most concise manner possible, so as to include everything that is important.
