| Exam #1 -Monday Sept 27
A few possible problems that might be on the exam--depends on whether I can work out the numbers. Does anyone have suggestions?: 1) Decision Tree--Putting shields on gas tanks in cars ($8.59 per car) would prevent some number of deaths by burning in rear-end collisions. How much would punitive damages in lawsuits have to be to give auto manufacturers enough incentive to install these shields? Here is a problem recently presented to MBA students in MSIS483. You need Acrobat Reader to see this file, but you can download it free. A simplified version, with the tree already drawn, may be on this exam. 2) Break Even Analysis--A merchant credit card account can be set up with all kinds of different cost structures. I recently set up credit card acceptance at a website and made the decision on which deal to use based on projected volumes and breakeven analysis. 3) Game Theory--Spam (electronic junk mail) differs from junk paper mail in that the recipient, rather than the sender bears the cost. Bulk paper mail costs a minimum of 30-50 cents a piece (postage, materials and supplies, design, and labor). Sending 50 million would cost upwards of $15 million. But e-mail is cheap. Spam only has a small fixed cost as you use other people's bandwidth to send send them all those get-rich-quick and improve-your-sex-life messages. If only a few people send spam, they get rich because they only need a very small response rate when sending 50 million solicitations. The cost of this is distributed over the millions of recipients, who have to pay for the connect time and spend time sorting and disposing. If a lot of people send spam, then the cost becomes outrageous and even the spammers get swamped in the cost of receiving and handling it. The Internet collapses. The prisoner's dilemma model predicts that--- ....? I might come up with some numbers for this and put the problem on this exam. |
