Media as watchdogs: The role of news media in electoral competition

We develop an equilibrium model to analyze the role of the media in electoral competition. When policy payoffs are state-dependent, party policies do not converge to the median voter's ideal policy if the media report only party policies. News analysis about the state, though possibly biased, can discipline off-equilibrium deviations and make the parties adopt more centrist policies. Since voters are rational, the party favored by the media need not win with a higher probability. Instead, media bias may reduce the effectiveness of electoral competition and lead to more polarized policies.
