Preliminary Reports

Field Before After
Preliminary Report Completion Date November 23, 2018
Preliminary Report Abstract We find that sending 10000 letters informing farmers about the program increases contacts taken by farmers to ask information by 323±40, the subscription of contracts by 63±40 (a 30% increase) without degrading the environmental quality of the contracts signed, at a costs of 100 Euros per additional contract. Overall our results suggest thatsending a simple reminder letter can be a cost-effective way to increase the take up rate of PES. Nudges beyond the information letter fail to provide similar effects, but, in view of their small cost, larger experiments might be warranted to investigate whether they might have very small positive effects.
