Under a fixed rent contract, however, the worker is the residual claimant and hence is not expected to shirk in his supply of labor effort. On the other hand, and especially if the fixed rent contract were only for a short period of time, Both the landowner and especially the worker have an incentive to shirk on maintenance activities and / or to over - or mis-use the land so as to get more output in the short run (at the cost of less future output). In addition, the owner of land may not have an incentive to share with the worker specific knowledge of the land he possesses.
