Locus of Control and Investment in Risky Assets – Journal of Economic Behavior & Organization (2020), 177: 548-568

with Andries de Grip, Didier Fouarge, and Raymond Montizaan.

[Ungated version]

Internal locus of control is an important personality trait strongly related to many economic outcomes. We show that the probability to own equity and the share of equity in household portfolios increase with people's internal locus of control. We explore, and find no evidence for, the hypothesis that this relation is driven by a link between internal economic locus of control and subjective expectations about the return and risk of investment in equity. The relation between locus of control and investment in equity also remains after controlling for risk and time preferences, financial literacy, overconfidence, optimism, trust, and other personality traits. We also show that locus of control has a stronger relation with investment in equity for financially illiterate investors. Our results document a strong and robust relation between locus of control and investment behaviour that cannot be explained by leading behavioural investment theories.

Are Professors Worth It? The Value-added and Costs of Tutorial InstructorsJournal of Human Resources (2020), 55(2): 836-863

A substantial share of university instruction happens in tutorial sessions— small group instruction given parallel to lectures. In this paper, we study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial groups. We find this to be largely not the case. Academic rank is unrelated to students’ current and future performance and only weakly positively related to students’ course evaluations. Building on these results, we discuss different staffing scenarios that show that universities can substantially reduce costs by increasingly relying on lower-ranked instructors for tutorial teaching.

Students are Almost as Effective as Professors in University Teaching – Economics of Education Review (2019), 73(101912)

In a previous paper, we have shown that academic rank is largely unrelated to tutorial teaching effectiveness. In this paper, we further explore the effectiveness of the lowest-ranked instructors: students. We confirm that students are almost as effective as senior instructors, and we produce results informative on the effects of expanding the use of student instructors. We conclude that hiring moderately more student instructors would not harm students, but exclusively using them will likely negatively affect student outcomes. Given how inexpensive student instructors are, however, such a policy might still be worth it.

Parenting Style as an Investment in Child DevelopmentJournal of Population Economics (2019), 32: 1315-1352

with Deborah Cobb-Clark and Anna Zhu.

[Ungated version] [Online Appendix] [Erratum]

We propose a household production function approach to human development that explicitly considers the role of parenting style in child rearing. Specifically, parenting style is modeled as an investment that depends not only on inputs of time and market goods, but also on attention. Our model relates socioeconomic disadvantage to parenting style and human development through the constraints that disadvantage places on cognitive capacity. We find empirical support for key features of our model. Parenting style is a construct that is distinctive to standard parental investments and is important for young-adult outcomes. Effective parenting styles are negatively correlated with disadvantage.

A Short Note on Discrimination and Favoritism in the Labor MarketThe B.E. Journal of Theoretical Economics (2017), 17(1)

with Jan Feld.

[Ungated version]

We extend Becker’s model of discrimination by allowing firms to have discriminatory and favoring preferences simultaneously. We draw the two-preference parallel for the marginal firm, illustrate the implications for wage differentials, and consider the implied long-run equilibrium. In the short-run, wage differentials depend on relative preferences. However, in the long-run, market forces drive out discriminatory but not favoring firms.

Endophilia or Exophobia: Beyond DiscriminationEconomic Journal (2016), 126: 1503–1527

with Jan Feld and Daniel S. Hamermesh.

[Media coverage: The Telegraph, RES Media Briefings, WSJ]

The discrimination literature treats outcomes as relative. But does a differential arise because agents discriminate against others – exophobia – or because they favour their own kind – endophilia? Using a field experiment that assigned graders randomly to students’ examinations that did/did not contain names, we find favouritism but no discrimination by nationality nor by gender. We are able to identify these preferences under a wide range of behavioural scenarios regarding the graders. That endophilia dominates exophobia alters how we should measure discriminatory wage differentials and should inform the formulation of anti‐discrimination policy.
