1/n 2/N

Great research analyzing the dissimination of misinformation & what to do about it has been produced by @DG_Rand @Sander_vdLinden @GordPennycook @jayvanbavel... et al. (& their teams)

They show how pervasive misinfo spread is & how people reason at the individual level.

☢️New @CESifoGroup WP☢️
⦿I quantify impact of political polarization on social preferences via 15(!) incentive-compatible experiments
⦿I also test if #nudging can reduce polarization (it can't)


Short🧵on what's new in this version 1/7

1st of all, the paper contains many experiments and interventions. After the initial submission of this paper, reviewers asked to not only quantify the detrimental impact of polarization but also test behavioral interventions to alleviate it.

So now I have ~9,000 obs.

💥New WP: Hate Trumps Love💥
RQ: study behavioral-, belief- & norm-based mechanisms through which perceptions of closeness, altruism & cooperativeness are affected by political polarization under @realDonaldTrump

Findings: it’s grim

🚨New WP (theory + experiment): lying & belief distortion under norm-uncertainty🚨
w/ @cbicchieri (@Penn) & Sonderegger (@CeDEx)

A: self-serving belief distortion

Thread ⬇ 1/

#Lies are ubiquitous & people often lie for their own benefit or for others (@UriGneezy et al., 2018 AER, Abeler et al., 2019 Ecta)
◈ Reasons (not) to lie: ethical dissonance, image concerns...

--> we take a complementary approach: norm-following considerations

🚨WP on deterrence & optimal design of institutions🚨
(w/ colleagues @econ_uzh @UniCologne @kielinstitute)

RQ: How to design institutions effective at deterring deviant behavior & recidivism?
A: Proper use of swiftness & uncertainty


Thread 1/n Governments use substantial resources to keep society safe and punish people for criminal acts. Mass incarceration is both costly and ineffective.

Understanding how to design proper institutions is important from both the social and economic perspective.
