Abstract

We show that Stiglitz's (1974) classic principal-agency theory of share tenancy does not imply, as alleged, that the optimal tenant share is less than one for risk-averse tenants nor that the share decreases monotonically with the tenant's inherent risk aversion. Tenants may self insure by working harder--increasingly so for higher levels of risk aversion--with the result that the more risk averse work for higher instead of lower shares. When the model is parameterized based on previous studies of Philippine agriculture, it predicts a U-shaped relationship between optimal tenant's share and inherent risk aversion. Landlords choose rent contracts for both high and low levels of risk aversion. For intermediate levels, the optimal sharing rates are 80% and above. In contrast, actual sharing rates in the study area ranged from 50-60%, with most farmers contracted on a 50:50 basis. We conclude that the risk-aversion versus moral hazard theory of tenure choice is incomplete. Rent contracts must have additional disadvantages and/or share tenancy additional benefits that are not accounted for in the static principal-agency theory.
