In this paper we aim at theoretically grounding the Reducing Emissions from De- 1 ically different information rent / efficiency trade-off. If the contract is performancebased (resp. conditionality-based), information rents are awarded to countries with the ex ante lowest (resp. highest) deforestation. In a simple quadratic setting, there is a reference level threshold in terms of efficiency towards less deforestation. In terms of expected welfare, conditional avoided deforestation-based schemes are preferred.JEL classification: D82, O13, Q23, Q54.
