Proxy Variables
The following equation relates a binary indicator for
having health insurance coverage to price and a binary
indicator for being averse to risk:
insured =
Bo + Bıprice + Bariskaverse + u
Suppose that data on riskaverse is not available but
data on bungee is available. The variable bungee is one if
the person has done bungee jumping at least once in the
past 6 months and zero otherwise.
