expected cost is $180,000 and Firm B’s net profit is $380,000. There is plenty
of room for a mutually beneficial price in between. Consider each of the
contracts in turn.
Under specific performance, delivery is mandatory. If the negotiated price
were (say) $280,000, then Firm B’s profit would be 380,000 – 280,000 =
$100,000, and Firm S’s expected profit would be $280,000 – $180,000 =
$100,000. The combined profit is $200,000.
Under reliance, Firm S would choose to default if there is a partial stoppage
or a strike. By defaulting, it must pay back $280,000 + $100,000 = $380,000
which is cheaper than delivering at a cost of $400,000 or $600,000. Firm B’s
expected profit is (.8)(100,000) = $80,000. (Firm S defaults 20% of the time,
forcing Firm B to forfeit the building contract and leaving it with zero profit.)
Firm S’s expected profit is:
(.8)(280,000 – 100,000) + (.2)(-100,000) = $124,000.
Thus, the combined profit is $204,000.
Under expectation, Firm S would choose to default only if there is a strike.
By defaulting, it must pay back $480,000 (it keeps the $280,000 contract
price) which is cheaper than delivering at a cost of $600,000. Firm B receives
a guaranteed profit of $100,000. If Firm S defaults (when there is a strike), it
must forfeit the construction contract but it is indemnified $480,000 by Firm
S. Its profit is: 480,000 – 280,000 – 100,000 = $100,000. Firm S’s expected
profit is: 280,000 – [(.8)(100,000) + (.1)(400,000) + (.1)(480,000)] =
$112,000. Thus, the combined profit is $212,000.
Of the three options, the expectation contract is most efficient; it generates
the greatest total profits to the parties together. It ensures that delivery is
made in the “right” circumstances: under normal work conditions or partial
stoppage. The buyer’s benefit from delivery is always $480,000 (the
$100,000 setup cost is already sunk). Thus, it is efficient to deliver when the
supply cost is $100,000 or $400,000. But, delivery is inefficient when the
supply cost is $600,000 (i.e. exceeds the buyer’s $480,000 gain). By
penalizing the supplier an amount that reflects the buyer’s gain, the
