TL;DR
This paper examines how interventions affecting media misreporting costs influence information accuracy and voter welfare, revealing complex effects that challenge common intuitions and depend on strategic interactions.
Contribution
It provides a strategic model showing that increasing misreporting costs can sometimes lead to more persuasion, challenging traditional views on media regulation effects.
Findings
Higher costs may increase misreporting and persuasion.
Low costs lead to full information revelation.
Interventions increasing misreporting costs are generally welfare-improving.
Abstract
It is believed that interventions that change the media's costs of misreporting can increase the information provided by media outlets. This paper analyzes the validity of this claim and the welfare implications of those types of interventions that affect misreporting costs. I study a model of communication between an uninformed voter and a media outlet that knows the quality of two competing candidates. The alternatives available to the voter are endogenously championed by the two candidates. I show that higher costs may lead to more misreporting and persuasion, whereas low costs result in full revelation; interventions that increase misreporting costs never harm the voter, but those that do so slightly may be wasteful of public resources. I conclude that intuitions derived from the interaction between the media and voters, without incorporating the candidates' strategic responses to…
