“…Empirical papers studying self-selection have highlighted the effects of different incentive schemes both in the lab (Niederle and Vesterlund 2007;Eriksson, Teyssier, and Villeval 2009;Dohmen and Falk 2011) and in the field (Dohmen and Falk 2010;Buser, Niederle, and Oosterbeek 2014;Dal Bó, Finan, and Rossi 2013;Ashraf, Bandiera, and Lee 2018). Carpenter and Myers (2010) and Hanna and Wang (2017) as well as Barfort et al (2016) analyze the role of altruism and (dis-) honesty in selection into public service, using samples of US volunteer firefighters and university students in India and Denmark, respectively. While these studies use experimental games like we do to measure motivation, the results are based on active volunteers or hypothetical job preferences only, thus making it difficult, for reasons explained above, to pin down actual self-selection.…”
