Introduction

A new wave of polarization across American society raises an important question: does partisanship extend its influence beyond politics into our everyday economic lives? This research explores that very question through three distinct field experiments.

Field Experiments Findings

* Workers systematically request lower reservation wages when employers share their political stance in online labor markets, suggesting a preference for partisan alignment even in economic transactions.

* Consumers show a marked preference for dealing with co-partisans across two separate studies, regardless of the platform or product involved.

Mechanism and Scope

This partisanship-driven behavior appears robust across different research designs:

* Strongly felt by those with strong partisan attachments in online labor markets.

* Even extending to weaker partisans through incentivized survey experiments targeting broader populations.

Significance

These findings demonstrate that the social and economic consequences of political identity are not confined to formal politics. Partisanship spills over into non-political settings, influencing cooperation and decision-making in ways previously unexamined.
