We have a new paper out in Ecological Economics in which we examined the potential success of coordination for biological control among farmers from a real landscape (from the North of Brittany - with hedgerows and everything - for the ones who know). #NoPesticides (1/5)
I am personally a bit happier than usual for a publication because this is my first 100% interdisciplinary paper : Claudine is landscape agronomist, Hugues is from computer science and, well, economics here. (2/5)
This was also the first paper I started during my PhD thesis. And the last one I finished... (3/5)
Yep, interdisciplinary takes time (I can't remember the number of time I had to explain the principle of the Nash equilibrium) but the experience totally worths it. I have learned a lot with Hugues and Claudine. Thanks! (4/5)
#Spoiler: there is only a small probability that the grand coalition can be stable (cause: heterogeneity of the farmers). Coordination for biological control is unlikely in real world. (5/5)
(Or, at least, not in large groups of farmers #StayTuned)

It's finally out ! With Alex Gohin (@SmartLereco), we have a new paper in @AnnalsOf in which we measure the market and environmental impacts (noinpoint source pollutions, imported deforestation, carbon emissions) of French #pesticide policies: jstor.org/stable/10.1560…
👇
What did we do on this paper?
First, we conducted a structural econometric estimation of the impact of output and input prices on the farmers' production decisions, including land-use decisions and pesticide applications.
What's new there?
Well, we used a detailed database from @InseeFr where all farming types (including vineyards and fruit production, which use many pesticides, but also breeding farms) are included for the whole France from 1990 to 2015.
You can check our new paper in Environmental and Resource Economics with Pierre Dupraz (@SmartLereco, @INRAE_France) in which we measure the productivity of biodiversity and its interaction with fertilizers and pesticides link.springer.com/article/10.100…
We measure biodiversity using habitat indicators (crop diversity and permanent grassland proportion) and estimate several system of production functions (with +/- detailed specifications) in 1000 farms of northwest France #econometrics
Highlights: 1) crop diversity is an input for cereals & milk 2) permanent grassland is an input for cereals when crop diversity is low 3) crop diversity & permanent grassland can substitute each other 4) they can also substitute with pesticides & fertilizers
