This paper studies the causal effect of providing information about climate changeon individuals’ willingness to pay to offset carbon emissions in a randomizedcontrol trial. Receiving truthful information about ways to reduce CO2 emis-sions increases individuals’ willingness to pay for CO2...

In Spence's (1973) signaling by education model and in many of its extensions, firms can only infer workers' productivities from their education choices. In reality, firms also use sophisticated pre-employment auditing to learn workers' productivities. We characterize the trade-offs between...
