The Relationship Between a Pure-Strategy Nash Equilibrium and a Dominant-Strategy

Multiple Choice

The relationship between a pure-strategy Nash equilibrium and a dominant-strategy equilibrium is that:

A) a dominant-strategy equilibrium is a special case of a pure-strategy Nash equilibrium.
B) a pure-strategy Nash equilibrium is a special case of a dominant-strategy equilibrium.
C) they are the same.
D) there may not be a dominant-strategy equilibrium, but there always is a pure-strategy Nash equilibrium.
E) they are mutually exclusive and exhaustive, in that a dominant-strategy equilibrium is the same thing as a mixed-strategy Nash equilibrium.
