RT Monograph SR 00 A1 Hopfensitz, Astrid A1 Mantilla, Cesar A1 Miquel-Florensa, Josepa T1 Conditional rewards for sustainable behavior: targeting lessons from an open access fishery YR 2016 FD 2016-03 VO 16-633 SP 55 K1 Artifactual field experiment K1 dynamic resource K1 artisanal fishery K1 stochastic production function AB We design and conduct a lab-in-the-field experiment to test the effect of a conditional contract on the sustainability of an open access fishery, where unit prices are conditional on aggregate catch. The contract provides collective incentives to decrease extraction but maintain the individual incentives of extraction maximization. We conduct the experiment with two communities of artisanal fishermen differing in their market and technological restrictions. We find that the conditional contract, compared to a fixed price scheme, increases efficiency, the duration of the resource and the total yield. The contract has a greater effect upon groups from the less restricted community.
