In this article, we reflect on "farmer surveys" in three European countries. Exciting to be part of this meta-science exercise. We learned a lot about our surveys. Hopefully, others find this useful. Would not have been possible without the excellent lead of Thomas Slijper.

Just finished Annika Norlin’s “Colony.” It’s a captivating story about a journalist with burn-out who goes into the woods and encounters a strange commune of outsiders. Very fun to learn about all of their backstories and figure out what happened 🧩

New paper in the #JARE 📄 🥳

To celebrate 50 years of the Journal of #Agricultural and #Resource #Economics, we contributed our paper "Advancing Agri-Environmental Policy with Behavioral and Experimental Economics: Insights, Innovations, and Future Directions" to the latest special issue. 1/4
Advancing Agri-Environmental Policy with Behavioral and Experimental Economics: Insights, Innovations, and Future Directions In recent years, behavioral and experimental economics have increasingly shaped agrienvironmental research by revealing how farmers navigate complex decisions. This article reviews key developments in three areas: behavioral insights into farmers’ social, temporal, and risk preferences and identities, norms, and motivations; experimental methods for assessing behavior and policy impacts; and methodological advances enhancing scientific rigor. We highlight contributions to more behaviorally informed agri-environmental policies, including nudges, participatory approaches, and innovative schemes. Looking forward, priorities include large-scale collaborative studies, stronger stakeholder involvement, and integrating behavioral evidence into policymaking, addressing challenges such as farmer fatigue, to design adaptive, effective, and legitimate policies.

Gambetta & Origgi on the LL Game, in which agents prefer to deliver and receive (!) low quality.

This paper is absolutely savage but also feels uncomfortably relevant to parts of academia outside of Italy 👀

diegogambetta.org/wp-content/u...
Abstract We investigate a phenomenon which we have experienced as common when dealing with an assortment of Italian public and private institutions: people promise to exchange high-quality goods and services, but then something goes wrong and the quality delivered is lower than had been promised. While this is perceived as ‘cheating’ by outsiders, insiders seem not only to adapt to, but to rely on this outcome. They do not resent low-quality exchanges; in fact, they seem to resent high-quality ones, and are inclined to put pressure on or avoid dealing with agents who deliver high quality. The equilibrium among low-quality producers relies on an unusual preference ranking which differs from that associated with the Prisoners’ Dilemma and similar games, whereby self-interested rational agents prefer to dish out low quality in exchange for high quality. While equally ‘lazy’, agents in our low-quality worlds are oddly ‘pro-social’: for the advantage of maximizing their raw self-interest, they prefer to receive low-quality goods and services, provided that they too can in exchange deliver low quality without embarrassment. They develop a set of oblique social norms to sustain their preferred equilibrium when threatened by the intrusion of high quality. We argue that high-quality collective outcomes are endangered not only by self-interested individual defectors, but by ‘cartels’ of mutually satisfied mediocrities.
