    Abstract: The previously documented trend toward more co- and multi-authored research in economics is partly (perhaps 20 percent) due to different research styles of scholars in different birth cohorts (of different ages). Most of the trend reflects profession-wide changes in research style. Older scholars show greater variation in their research styles than younger ones, who use similar numbers of co-authors in each published paper; but there are no differences across cohorts in scholars' willingness to work with different coauthors. There are only small gender differences in the impacts of age on numbers of coauthors, but substantial differences on choice of coauthors.

    Abstract: Many prior studies suggest that alphabetic ordering confers professional advantages on authors with earlier surname initials. However, these studies assume that authors select into coauthorships without regard to the incentives identified. We consider the alternative and develop a model of endogenous selection into single and coauthorships for economics, which uses alphabetical ordering. We then tested it with authorship data from economics, with management (which does not use alphabetical ordering) as a benchmark. We predicted that lower “quality” authors with earlier surnames would be less desirable as coauthors, while higher quality authors with later surnames would have a lower desire to coauthor. Both types of authors are therefore more likely to single- author. Furthermore, higher quality authors with earlier surnames should have more and better coauthoring options. Consistent with our predictions, we found citation ranks were increasing on surnames for single-authored works and decreasing for coauthored in economics, both absolutely and compared to management. Also as predicted, this effect is driven by lower-tier journals in which there is likely a thinner market for coauthors. Furthermore, comparing citation ranks of first-authors of alphabetical and nonalphabetical papers shows that the “larger share” effect of being first is dominated by the “smaller pie” effect of selection from second authors who will accept a smaller share.

    Abstract: We exploit a natural experiment based on the Italian promotion system for associate and full professor positions to investigate gender differences in the willingness to enter competition. Using data on about 42,000 professors and controlling for productivity and a number of individual and field characteristics, we find that females have a lower probability of applying for competition of about 4 percentage points. The determinants of this gap seem to be gender differences in risk-aversion and self-confidence and women’s fear of discrimination: the lower tendency to enter competition is especially relevant for women in the lower tail of the distribution of scientific productivity and in fields in which productivity is not easily measurable; furthermore, women are less likely to apply for promotion in fields in which promotions of females in the past were rare.
    Keywords: Attitudes towards competition; Gender gaps; Risk-aversion; Self-confidence; Discrimination; Academic Promotions; Natural Experiment.
