چکیده
How much influence can the media exert on the political process and how can regulation reduce such influence? We define media power as the ability of subsets of jointly owned media outlets to affect electoral outcomes by providing biased information to voters. We characterize the worst-case scenario media power index over a range of assumptions on the beliefs and attention patterns of voters. We identify circumstances where the power of a media organization can be expressed in terms of attention share. Within our model, the power index can be used to assess the maximal damage produced by media mergers.
