Sa. Dunne et Ma. Loewenstein, COSTLY VERIFICATION OF COST PERFORMANCE AND THE COMPETITION FOR INCENTIVE CONTRACTS, The Rand journal of economics, 26(4), 1995, pp. 690-703
This article analyzes the optimal linear incentive contract to offer t
o would-be agents competing for a principal's project when the princip
al finds it costly to observe an agent's cost performance ex post and
cannot commit to a monitoring policy ex ante. Cost sharing reduces the
winning bidder's informational rents but creates an incentive for the
agent to pad costs ex post and to slacken his effort. The optimal cos
t-sharing parameter generally differs from that when monitoring is cos
tless, and it is higher the fewer the number of bidders and the larger
the variance of their idiosyncratic cost.
