RT Monograph SR 00 A1 Panova, Elena T1 Media market structure and confirmatory news YR 2025 FD 2025-03 VO 24-1597 SP 16 K1 quality of news K1 competition K1 reputational cheap-talk AB This paper extends the reputational cheap-talk model to study the effect of media market structure on the quality of news, depending on news coverage characterized by: (i) the precision of common priors and (ii) the likelihood of follow-up quality assessment. We find that competition (weakly) increases the quality of news, except when the news covers controversial issues, the quality of which is likely to remain uncertain, such as politics. Competition adversely affects the quality of such news by increasing the elasticity of demand, thereby creating incentives to confirm common priors.
