Abstract
Agro-environmental schemes (AES), which pay farmers to adopt greener practices,
are increasingly important components of environmental and agricultural policies
both in the US and the EU. Here we study the French implementation of the
EU AES program. We estimate additional and windfall effects of five AESs for
a representative sample of individual farmers using Difference-In-Difference (DID)
matching. We derive the statistical assumptions underlying DID-matching from a
structural household model and we argue that the economics of the program make
it likely that these assumptions hold in our data. We test the implications of the
identifying assumptions, provide a lower bound using triple-difference matching,
test for crossover effects and insert our estimates of both additionality and windfall
effects into a cost-benefit framework. We find that the AESs promoting crop
diversity have inserted one new crop into the rotation but on a small part of the
cropped area. We also find that the AES subsidizing the planting of cover crops has
increased cover crops by 10 hectares on the average recipient farm at the expense of
almost 7 hectares of windfall effect. This AES does not appear to be cost effective.
In contrast, we find that the AES subsidizing grass buffer strips could be socially
efficient despite large windfall effects. We finally estimate that the AES subsidizing
conversion to organic farming has low windfall effects and high additionality.
