Abstract

Sell-side analysts frequently collaborate with their peers in producing research reports. We examine whether such co-authorship influences analyst career outcomes. Our findings suggest that co-authorship in analyst reports is an important determinant of analyst ranking. Specifically, analysts issuing more co-authored reports and collaborating with more peers are more likely to be ranked than their counterparts. Moreover, the effects of co-authorship are stronger: a) for analysts co-authoring with previously ranked peers than for those collaborating with unranked peers and b) for previously unranked analysts than ranked analysts. Further analysis reveals that co-authorship may also affect the ranking level of repeatedly ranked analysts. Overall, co-authorship has positive implications for analyst career progress.
