Does distrust in politically affiliated media induce a bias in investor beliefs? We study the acquisition of Dow Jones & Co. by News Corporation in 2007 as a shock to the political affiliation of Dow Jones outlets. Following the acquisition, the prices of Republican- (Democrat-) aligned stocks become less sensitive to favorable (unfavorable) Dow Jones Newswires (DJNW) sentiment, consistent with the market attaching less credibility to a politically affiliated source. There is, however, no evidence of change in DJNW sentiment, coverage, or language about Republican/Democrat stocks, suggesting a loss of stock price informativeness. Consistent with this view, a portfolio exploiting the attenuated reaction to DJNW news earns abnormal returns following 2007.

ABSTRACT We study plaintiff law firms in corporate litigation, focusing on “star” firms that dominate settlement outcomes. Stars are associated with larger settlements; however, much of this effect is predicted by the defendant's litigation insurance coverage, suggesting assortative matching of stars with lawsuits that have ex ante larger expected payoffs. Moreover, stars charge higher fees for a given settlement size. Additional tests suggest that visibility and information asymmetry vis‐à‐vis less sophisticated plaintiffs help sustain the stars’ market share. These findings advance our understanding of corporate litigation and the agency relationship between plaintiff law firms and their clients.
