Contracts in cattle production in Ghana: their nature, and effects on input use and technical efficiency

Samenvatting (Engelstalig)

This thesis studies cattle production contracts in Ghana, mostly through primary data, including survey and experimental data. We observe two main contracts, one between kraal owner and herdsman and another between kraal owner and cattle owner. Contract type variations are explained by the cost involved in maintaining these contracts and by the need to provide those concerned with incentives to give their best. Also, some contract types serve as mutual insurance for both parties. For the relation between kraal owner and cattle owner, it is shown that, compared with calves-sharing contracts, fixed-wage contracts promote more use of inputs that enhance short-term productivity. Contract type does not matter, however, for the use of inputs that enhance long-term productivity. Similarly, contracts do not influence the number of calves born in a kraal. Moreover, higher educated kraal owners are associated with lower number of calves born possibly because they have less time for supervision.
