Negatively correlated author seniority and the number of acknowledged people: Name-recognition as a signal of scientific merit?

Evidence from five general-interest journals in economics reveals an inverse relationship between author seniority and the number of colleagues whom authors choose to thank and acknowledge. The large seniority effect is insensitive to the inclusion of controls for the number of co-authors, number of pages, number of words in the title, and journal fixed effects. The data are consistent with the hypothesis that name-recognition is an important signal used by economists in evaluating scientific merit.
