Supervising - Economics, Law and Ethics

(Following on from your Security I supervisions:) In order to communicate securely about supervisions we need a way of authenticating emails.

Supervision 1 - lectures 1-4: Game Theory and microeconomics

Sign up for a supervision.

Spend at most 6 hours working on this, stop when you run out of time (I expect you to run out of time).
Exercises: pick two essays from the 3 possible and write ~800 words/2 sides of A4, do this first before attempting any of the other exercises. Then from Intermediate Microeconomics: 1.7, 2.6, 3.8, 4.7, 5.3, 14.1, 15.4, 16.4, 24.4, 25.1, 28.2, 28.5, 32.5, 33.4, 34.1, 35.3, 36.3 (I have tried to pick the most interesting question on each topic, if you don't think it is worth doing, skip it).

Please write a cohesive paper / essay of approximately 800 words. It would be smart if you wrote by hand, because that is a helpful preparation for the actual exams. It is up to you, though. Do not simply produce bullet-pointed lists. Work your answers into the text. It does not particularly matter what citation style you use, as long as you are consistent. (This text and options 2 and 3 from David Modic)

  1. Why do monopolies form in information technology? What can regulators do to stop it? Should they?
  2. Give me an example of a zero-sum game in your life right now (regardless of direction). How would you turn this situation into a Nash-equilibrium type of payoff? And why would you want to? In a business setting, which is better in the long run: zero-sum or Nash-equilibrium? Why? Can you change a zero-sum game into a stag hunt type of game by introducing alternative payoffs? How and what kind of payoffs?
  3. What is utility? Give me a loose definition. Do different people expect different types of utility from a given transaction? Let's say you are offering a service. Describe it in a sentence or two. What kinds of incentives should you implement in order to improve the perceived expected utility of your service? Should the incentives be monetary or of some other kind? What else is a possible incentive? Why is it that Apple has more money than Microsoft, but Microsoft has a bigger user base? Have different incentives anything to do with it?

Supervision 2 - lectures 5-8: Rationality, Risk, Auction theory, Law, Ethics, Policy

Essays (as for supervision 1):

  1. How should an IT company behave?
  2. What strategies can you use to effectively pursue people and organisations which attack your systems? What makes this difficult?
