This article characterizes the optimal corporate fire insurance contract wh
en the insured firm has private information about the economic value of the
damaged assets. It is shown that the indemnity should be lower when the fi
rm receives insurance money than in case of reinstatement, but there should
be partial coverage even when reinstatement is chosen. When a risk of arso
n exists, the insurer may only reimburse reinstatement costs.
Finally, the optimal contractual arrangement specifies that, in order to di
scriminate among firms, the insurer may use a (randomly exercised) reinstat
ement option as a screening device.
