New Working Paper w/ Aristotelis Epanomeritakis

Applications often use experiments with other evidence to estimate counterfactuals hard to identify with a single experiment. Examples include GE effects or external validity. Which experiments to run (and how) in these contexts?

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.

Happy to share our latest pub on Ecological Econ. By means of a field exp at the @eaere.bsky.social 2022 Annual Conference, we show that increased visibility of one's food choices relatively affects their sustainability. Joint work with @atavoni.bsky.social, Astrid Dannenberg and Eva Weingärtner.

Food choices and in particular meat consumption have major impacts on the local and global environment, which is why the topic is gaining attention in…

An #AI chatbot designed for Nov 2024 California ballot initiatives reduced voters' perception of the effort needed to get more information, increased voter engagement, and improved voter understanding.

Graph showing that voters who used the Ballotbot AI to learn about California's ballot initiatives performed better on in-depth questions that tested their understanding.

Citizens need clear, accessible information to make informed decisions, but today’s digital landscape can be overwhelming. This column tests whether an AI chatbot can ease election information overload for 1,500 Californian voters. The chatbot reduces the voters’ perception of the effort needed to get more information, increases voter engagement, and improves the accuracy of their understanding – especially among those who initially know less about the issues. For policymakers, this suggests transparent AI tools can help reduce inequalities in representation, but only if users trust their performance.
