One-paragraph thesis:

A small group of hyper-persistent consumers, dubbed "nudniks," play a crucial role in market discipline by actively challenging seller misconduct, benefiting all consumers. However, sellers increasingly use big data to identify and neutralize these nudniks, undermining accountability. Arbel calls for legal strategies to protect this vital "nudnik-based activism" and preserve its positive spillovers, shifting focus from mythical contract-readers to these real-world enforcers of market norms.

What this paper is about:

A small group of hyper-persistent consumers, dubbed "nudniks," play a crucial role in market discipline by actively challenging seller misconduct, benefiting all consumers. However, sellers increasingly use big data to identify and neutralize these nudniks, undermining accountability.

Core claims:

1. A small group of hyper-persistent consumers, dubbed "nudniks," play a crucial role in market discipline by actively challenging seller misconduct, benefiting all consumers. However, sellers increasingly use big data to identify and neutralize these nudniks, undermining accountability. Arbel calls for legal strategies to protect this vital "nudnik-based activism" and preserve its positive spillovers, shifting focus from mythical contract-readers to these real-world enforcers of market norms.

2. "nudniks" are hyper-persistent consumers with idiosyncratic utility functions who challenge seller misconduct *ex post*, even when costs outweigh benefits, acting where most remain passive.

3. Distinct from passive consumers or pre-purchase focused "shoppers," nudniks are driven by fairness, spite, or ideology, often being derided despite their crucial role.

4. Nudniks act as engines of market discipline, generating positive spillovers by publicly airing grievances, litigating, and creating reviews, thus deterring unfair practices and enforcing market norms benefiting all.

5. Their actions solve collective action problems, provide monitoring for sellers, and can compel broad policy changes, enhancing both legal and reputational deterrence for the passive majority.

Firms leverage detailed consumer data to predict complaint likelihood and then disarm nudniks through tailored remedies, by muffling their voices, or by avoiding or "gagging" them.
