1) What types of games are especially suitable for calculating mixed strategy equilibria?

(Hint: Consider Matching Pennies as an example)

2) How is a limit pricing strategy used in an oligopoly to drive competitors from a market?

3) Is the Nash Equilibrium in The Prisoner's Dilemma Game - subgame perfect?

4) Why does rollback provide only Nash equilibria that are subgame perfect?

5) Why are refinements to Nash equilibria conceptually desirable in game theory?

6) How does marginal cost as a lower limit unite long-run perfect competition with Bertrand Oligopoly?
