Gentzkow and Shapiro end their paper with a pair of policy recommendations based on their ideas about compe ion. Domestically, they say the best check on bias is a compe ive media market, by which they mean limits on media ownership. Overseas, they counsel the U.S. government to combat alleged anti-Americanism in the media by stimulating compe ion—not with demands, for example, that Al Jazeera's sponsor, the emir of Qatar, censor his network.
The authors' great achievement is that they write intelligently about press bias without descending into a conversation-killing discussion of "objective" and "subjective" journalism. That said, I wish they'd tested their theory a bit more rigorously by applying it to the British press, which is both compe ive and excessively partisan. Despite the existence of the trans-Atlantic-flavored Economist and Financial Times, the four leading papers on the British newsstand—the Times, the Independent, the Guardian, and the Telegraph—contradict the Gentzkow-Shapiro thesis. Over there, compe ion has spawned newspapers whose major occupation is to provide a daily reaffirmation of one's worldview.
