which maximises their consumer surplus. A car will be purchased as
long as consumer surplus is non-negative. If the marginal cost of
each car is zero, which set of prices for the silver (pS) and gold
badged (pG ) cars will maximise profits if the retailer must engage in
menu pricing or second degree price discrimination?

Burgers?, are deciding whether to hire a security guard. The security
guard will provide deterrence to both stores. Each store will benefit
from the presence of a security guard by reducing theft. The payoff
matrix is given by and assume that Bill and Malcolm make their
decision simultaneously and that a higher number represents a
better outcome:

Malcolm doesn?t.
Bill doesn?t hire a guard but
Malcolm does.
Neither Bill nor Malcolm
hire a guard.
Both Bill and Malcolm hire a
guard.
