Over the past decades the number of news outlets has increased dramatically, but the quality of news products has declined. We propose a model to reconcile these facts where consumers’ attention allocation decisions not only depend on but also affect news outlets’ quality choices. When competition is intensified by new entries, the informativeness of the news industry rises. Thus, attention is diverted from existing outlets, reducing their incentives to improve news quality, which begets a downward spiral. Furthermore, when attention becomes cheaper, a larger number of news outlets can be accommodated in equilibrium, but news quality still falls. (JEL D83, L15, L82)
