It is proved for two-player normal form games that if a totally mixed Nash equilibrium exists then the entire set of Nash equilibria is (trembling-hand) perfect. More generally, it is proved that if there is a (trembling-hand) perfect equilibrium, then all Nash equilibria whose supports are...

I present an example showing it is sometimes efficient for a bank to commit to a policy that keeps information about its risky assets private. Current practices in banking result in bankers having private information: demand deposits are non-contingent contracts, there are time lags before the...

We describe two-person simultaneous play games. First, we use a zero sum game to illustrate minimax, dominant and best response strategies. We illustrate Nash Equilbria in the Prisoner's Dilemma and the Battle of the Sexes Game, and distinguish three types of Nash Equilibria: a pure strategy, a...
