24.5 Three types of contracts are used to specify the way in which tenants on a plot of agricultural land may pay rent to the landlord. Rent may be paid (1) in money (or a fixed amount of agricultural produce), (2) as a fixed proportionate share of the crop, or (3) in "labor dues" by agreeing to work on other plots owned by the landlord. How might these alternative contract specifications affect tenants' production decisions? What sorts of transactions costs might occur in the enforcement of each type of contract? What economic factors might affect the type of contract specified in different places or during different historical periods?
