There is an emerging consensus that carbon emissions must be limited. An attractive approach to promoting carbon reductions is to encourage reductions in deforestation. But any such strategy must confront a basic problem: agents that might be induced to reduce their actions which would reduce forests have private information about their opportunity costs. This concern seems particularly likely to apply in situations where there are significant related risks, as agents seem highly likely to differ in their tolerance for risk. In this paper, I investigate a contracting scheme designed to mitigate the asymmetric information problem where agents are heterogeneous in their tolerance for risk. Mechanisms that recognize the potential insurance value associated with the acquisition of sequestration services, and that pay attention to landholders’ private information about risk tolerance, offer a sensible way to approach the problem. These contracts are generally a cheaper approach to maintenance of forests than a simple, constant per-unit subsidy.
