The role of risk in contract choice

Structuring contracts to share risk in light of incentive problemsis the central premise of contract theory, yet the risk-sharingimplications have rarely been thoroughly tested using micro-levelcontract data. In this article we test the major implicationsof a principal-agent model of contracts using detailed dataon more than 4000 individual contracts from modern North Americanagriculture. On a case-by-case basis, our evidence fails tosupport the standard principal-agent model with risk aversionas an explanation of contract choice in modern North Americanfarming. At the same time, we find some support for models thatassume risk-neutral contracting parties and stress multiplemargins for moral hazard and enforcement costs.
