where c is the ultimate cost of the procurement (unknown at the time the
contract is signed). The remaining three variables are specified in the con-
tract: Tis the firm’s target profit, cTis its target cost, and b is its sharing
rate. If the actual cost matches the target cost (c cT), then the firm earns
its target profit: T. For positive sharing rates, the supplier and the
buyer share in cost overruns and underruns. For instance, if b .4, then
each extra dollar of cost is paid 40 percent by the firm and 60 percent by the
buyer. For b 1, the buyer writes a fixed-price contract; the supplier is
responsible dollar for dollar for cost overruns. At b 0, the buyer writes a
cost-plus contract; here the buyer pays for all overruns and the firm is guar-
anteed a fixed profit of T. For sharing rates between 0 and 1, the buyer
writes an incentive contract.
The trade-off between risk sharing and efficient firm selection is at the
heart of determining the “degree of incentive” (i.e., the value of b) in the con-
tract terms. Under a fixed-price contract, the winning supplier bears all costs
and, therefore, has an obvious efficiency incentive (i.e., will strive to keep costs
to a minimum). Since it bears full-cost responsibility, a firm’s price bid will nec-
essarily reflect its likely production cost (plus a provision for profit).
Consequently, by choosing the lowest competitive bid, the buyer also will be
selecting the lowest-cost firm. However, the disadvantage of the fixed-price con-
tract is that it allows no risk sharing. Being risk averse, the winning supplier
will require a much higher profit margin for bearing procurement risk and
will pass this premium on to the buyer via a higher price bid.
At the opposite extreme, a cost-plus contract insures the supplier com-
pletely against uncertainty about program cost. Accordingly, a risk-averse sup-
plier requires a much lower guaranteed profit fee (than with a fixed-price
contract). However, under a cost-plus contract, the firm has no incentive to
minimize cost (since the buyer picks up the tab). Furthermore, if cost-plus
contracts are set, the bidding competition is much less likely to select the most
efficient supplier.
In general, the buyer minimizes its expected procurement cost by fash-
ioning an incentive contract. (That is, neither the fixed-price nor cost-plus
extremes are optimal.) Determining an optimal incentive contract (the “right”
value of b) depends on a basic trade-off among the goals of risk sharing, effi-
cient firm selection, and incentives for cost reductions.

Bidding to Televise
the Olympics
Revisited
In light of our analysis of competitive bidding, what conclusions can we draw about the
networks’ fight for the Olympics television rights? First, consider the positions of the bid-
ders themselves. Bidding for the Olympics four or more years before the fact is fraught
with uncertainty. Much of this uncertainty is common to all bidders. A network’s adver-
tising revenues from televising the Olympics depend on the number of viewers advertis-
ers expect. Of course, viewer interest (in particular, American viewer interest) depends
